So again, these sessions are brat you by extension and generous support from the Minnesota, Soybean Research and Promotion Council and the Minnesota Corn Research and 00:00:22.000 --> 00:00:25.000 Promotion Council. I'm. Liz Stahl, Extension Educator. 00:00:25.000 --> 00:00:30.000 I work out of the Worthington Regional Office focusing on crop and moderating with me. 00:00:30.000 --> 00:00:41.000 Today we have Claire LaCanne. She is an Extension Educator and Rice and Steel counties, 00:01:16.000 --> 00:01:23.000 But a different spin on things we're gonna have a couple of polls today, too. 00:01:23.000 --> 00:01:38.000 So those of you that are participating live can answer those questions and those that are you that are listing on the podcast will kind of at least be able to explain what what people here i'm joining us live today. had their thoughts on But anyway, So with that I 00:01:38.000 --> 00:01:47.000 just wanted to turn it over to our first topic today again when honor test fight back, we're gonna look on the on the weed front, and so we have Dr. 00:01:47.000 --> 00:01:51.000 Tom Peters either extension weed scientists and sugar meat specialists. 00:01:51.000 --> 00:01:53.000 He works with *su and University of Minnesota. 00:01:53.000 --> 00:02:01.000 But first of all, if you want to put up that first poll and i'll see if our readers are well, people can see see that. 00:02:01.000 --> 00:02:10.000 Okay, So the first question is, we have 2 questions of this poll first one is, do you think it weed resistance to any of the following on land you farm or the land that you work with? 00:02:10.000 --> 00:02:19.000 And here you can select all that applied so we've got like like the seat ppo inhibitors, so like luxury, cobra als inhibitors like pursuit. 00:02:19.000 --> 00:02:24.000 First straight Hpd inhibitors like Callistol and lattice. 00:02:24.000 --> 00:02:32.000 I was fascinated. for example, liberty or at chazine or other, and the last option is No, I don't think so. 00:02:32.000 --> 00:02:37.000 And then there's a second question onto this too, so just scroll down in your screen. 00:02:37.000 --> 00:02:42.000 This one's asking what is the most common glyphosate resistant weed in Minnesota. 00:02:42.000 --> 00:02:55.000 We've got koso water have common ragweed, or glucose that resistant volume tier corn, so we'll give you just a couple more seconds to do this, and then we'll close that 00:02:55.000 --> 00:03:02.000 out. 00:03:02.000 --> 00:03:09.000 We would go about 60. Okay, 2 more seconds. Your choices here and you wanna close that out. 00:03:09.000 --> 00:03:19.000 Diane can share the results here. Okay, all right. And, Tom, you can take a look at this. 00:03:19.000 --> 00:03:25.000 I will let you review the answers to how that fits in with what you want to talk about today. 00:03:25.000 --> 00:03:29.000 But well, i'll i'll help you out a little bit yeah, we see glipacy. 00:03:29.000 --> 00:03:33.000 It's the number one for resistance to the following at 68% of the people. 00:03:33.000 --> 00:03:40.000 And then 20. Some percent of the als 27% say no, I don't think so. 00:03:40.000 --> 00:03:43.000 We have some people 18% with Ppo inhibitors. 00:03:43.000 --> 00:03:47.000 9% of the fascinate and 5% with atrazine. 00:03:47.000 --> 00:03:59.000 So, and the most common weed going to services. we in Minnesota was water. Hemp people are reporting was 77% to volunteer corn phone and 27%. 00:03:59.000 --> 00:04:05.000 So. Tom, i'll turn it over to you I know you have some things to share, or started with liberty. 00:04:05.000 --> 00:04:10.000 Liz i'd like to start with the first question. 00:04:10.000 --> 00:04:19.000 So i'll make comments regarding this when I go through my pictures for those that are listening. 00:04:19.000 --> 00:04:26.000 Participating this morning. I would like to make a comment about liberty, though. 00:04:26.000 --> 00:04:32.000 So 2 people mentioned liberty and possible liberty, resistance. 00:04:32.000 --> 00:04:42.000 I would encourage both of you to reach out to your regional educator, and first tell us where you where you live. 00:04:42.000 --> 00:04:58.000 And second, if possible. I would like to get a whole of a a sample a seed sample possibly to test that i'm not aware of any liberty resistance in Minnesota but that doesn't mean 00:04:58.000 --> 00:05:18.000 anything. So your observations are very important. and and If you're seeing some things that are unusual, we certainly need to to hear about him and and and see that so i'm gonna put up a a a a brief 00:05:18.000 --> 00:05:27.000 Powerpoint presentation, and i'm gonna talk a little bit about water hemp resistance. 00:05:27.000 --> 00:05:42.000 So. if if I query my colleagues in different parts of the country, and ask them what herbicide families have you observed resistance in? 00:05:42.000 --> 00:05:56.000 We get usually 6 families. so can you put that in presenter mode. we're just kind of seeing a small picture of that. 00:05:56.000 --> 00:06:02.000 I thought I did sometimes it's kind of funky on. 00:06:02.000 --> 00:06:08.000 Let's see that's not in presenter mall just a second. 00:06:08.000 --> 00:06:31.000 I'll try it again. Did that help at all that helps I know what i'm I I know what I forgot to do 00:06:31.000 --> 00:06:42.000 Is that better? There you go. Yeah, that looks good. So 6 families and I mentioned that that some of these are in Minnesota. 00:06:42.000 --> 00:07:00.000 Some of these are not in minnesota but but the scary thing that weed science to concern theirselves with is sometimes we'll have the same planned with multiple herbicide resistance. 00:07:00.000 --> 00:07:10.000 So in Minnesota I think it's very possible that our water help may have resistance to als Inhibitors Group. 00:07:10.000 --> 00:07:22.000 2 group 9, and the ppo inhibitors all in the same plant. So that's that's pretty scary. 00:07:22.000 --> 00:07:39.000 Now what I don't see a lot of is liberty resistance, and as I started with i'm not aware of any liberty resistance in in Minnesota and Eastern North Dakota but I wanna I 00:07:39.000 --> 00:07:56.000 wanna challenge everybody. I think liberty has to be our special it's the herbicide that we very carefully use in crop production to ensure that we don't have widespread resistance. 00:07:56.000 --> 00:08:01.000 So what that means is is, save it for one crop in the rotation. 00:08:01.000 --> 00:08:07.000 The one crop that you need or value liberty the most in. 00:08:07.000 --> 00:08:13.000 And then second, use liberty in a program, use it in conjunction with soil. 00:08:13.000 --> 00:08:25.000 Residual herbicides use a layering technique, and then save liberty for weeds that are less than 4 inches tall. 00:08:25.000 --> 00:08:30.000 If you're using it post emergence I call that application in June. 00:08:30.000 --> 00:08:40.000 Maybe early July liberty the closer because it's right at the end of the use label. 00:08:40.000 --> 00:08:54.000 No, I I do a lot of driving during the summer my my territory sugarbeat growers in Minnesota and North Dakota, and that's quite a few miles between these guys. 00:08:54.000 --> 00:08:56.000 So I get a chance to drive by a lot of fields. 00:08:56.000 --> 00:09:12.000 So I was observing a Soybean field, and in mid-july, towards the end of July Water, Hamp started to poke. God of this field and Liz, If we get a chance, we can talk. 00:09:12.000 --> 00:09:19.000 About Why, that might be occurring, and I I just you know I just made a note, boy. 00:09:19.000 --> 00:09:24.000 There's there's water hemp in that field well guess what. 00:09:24.000 --> 00:09:34.000 2 weeks 2 weeks later, in the last 2 weeks those water hamper, brown, and or at least the leaves are brown. 00:09:34.000 --> 00:09:41.000 So what I think is happening here is. The producer went out and sprayed the field. 00:09:41.000 --> 00:09:57.000 Probably because they were worried about seeds. that so waterhap is a prolific producer of seed and i'm guessing, the producers said, I don't want any of that going to see but 2 things all we're doing here 00:09:57.000 --> 00:10:01.000 is burning off the leaves we're not going to kill this plan. it's too big. 00:10:01.000 --> 00:10:10.000 The plant in the picture is at least 2 feet tall so we're gonna see regrowth here. 00:10:10.000 --> 00:10:16.000 But this is exactly the recipe that weeds take for developing resistance. 00:10:16.000 --> 00:10:30.000 They take advantage of maybe an awkward application, and we identify, maybe a very rare plant or population of plants, and those are the ones that proliferate. 00:10:30.000 --> 00:10:37.000 They're the ones that are able to survive and that's how resistance develops. 00:10:37.000 --> 00:10:50.000 So. so, Liz, I would encourage our our producers that are on the phone or l listening to this podcast, later to resist the urge to use liberty when you're copied the value. 00:10:50.000 --> 00:10:57.000 The chemistry, and for hand weeding, or excuse me for late escapes. 00:10:57.000 --> 00:11:04.000 I would consider other ideas for for eliminating those escapes, such as hand weeding. 00:11:04.000 --> 00:11:08.000 I know it's hard work I know it's still hot out. 00:11:08.000 --> 00:11:12.000 But that's the kind of activity we have to do to preserve our chemistry. 00:11:12.000 --> 00:11:18.000 Yeah, really good point time. And you know on your hand weeding, what do you think I mean? 00:11:18.000 --> 00:11:23.000 Cause we get questions sometimes. Do we need to remove the weeds out of the field? 00:11:23.000 --> 00:11:27.000 Or you know, a little key to just pull him and leave him lay. 00:11:27.000 --> 00:11:34.000 But you know at what point do you think we're getting viable seed, and I mean, do we need to worry about hauling them out of the field. 00:11:34.000 --> 00:11:45.000 Very important, very important question. So so here's the deal with water him water, hemp, seed is viable in 14 days. 00:11:45.000 --> 00:11:51.000 2 weeks after it. flowers, so I don't think we know for sure when it flowered. 00:11:51.000 --> 00:12:08.000 But if we're, going out there now this week the the week of the eighth of August would encourage everybody to carry him out of the field, bring a bag, carry him out of the field throw them in a burn barrel or something 00:12:08.000 --> 00:12:14.000 but don't just drop them because there's going to be a fair amount of viable seed there already. 00:12:14.000 --> 00:12:20.000 So. yeah, you probably you probably helped yourself. but you've gone through all the work to pull them. 00:12:20.000 --> 00:12:35.000 Carry them out of the field Now, if you're pulling out common ragweed or lamps quarters those those plants make viable seed much later in the season. so I wouldn't have any problem at all just pulling 00:12:35.000 --> 00:12:41.000 the common ragweed and letting it go. Good reason why we have a lot of water. 00:12:41.000 --> 00:12:53.000 Humphrey well and you know in tackle a bit about water in, but I don't know if you're ready to switch gears a little bit. but I i'm just intrigued by this 00:12:53.000 --> 00:12:57.000 question, too. We asked what's the most common glory for this, and we of Minnesota. 00:12:57.000 --> 00:13:03.000 77% of people said, water him. but volunteer corn came in the second at 27%. 00:13:03.000 --> 00:13:16.000 What's your take on this time Well, first of all there's a tremendous amount of volunteer corn out there, and and it makes sense, because I I think much of the the seed. Co. 00:13:16.000 --> 00:13:21.000 Much of the corn we plant has the glyphosate trade in there. 00:13:21.000 --> 00:13:29.000 So. I think a lot of our programs combined life isate with other things, and we're not getting it with glyphosate. 00:13:29.000 --> 00:13:37.000 But but here's the thing I think was we're using the the group one herbicides. 00:13:37.000 --> 00:13:52.000 But in many cases they're in combination with the group 4 herbicides, the oxen herbicides, and I don't care if you're using a dicampa program in soybeans or 2 ford colonel 00:13:52.000 --> 00:13:56.000 you you're gonna get antagonism mixing together Dwight. 00:13:56.000 --> 00:14:07.000 Mixing together. select Max, for example, and one of those oxen herbicides is not the most effective way to get volunteers. 00:14:07.000 --> 00:14:23.000 So the guys that are going through the work and and and and putting a herbicide out there are probably not realizing the the results that they're expecting no good good points, and you know to again when we're looking at 00:14:23.000 --> 00:14:27.000 this point, as i've seen these weeds poking through the fields. 00:14:27.000 --> 00:14:33.000 Really what what can we do? I mean? what what would you recommend what's what's kind of the process at this point we talked about hand weedy. 00:14:33.000 --> 00:14:38.000 I mean, is there anything to do? or should we just pretty much take notes and plan for next year? 00:14:38.000 --> 00:14:44.000 So so. so 3 things lives so first of all we're done spring 00:14:44.000 --> 00:14:52.000 I know we like to spray things it's fun to move our sprayers through fields. 00:14:52.000 --> 00:15:00.000 But is not the solution anymore. So let's put the sprayer away, especially for our roll crops. 00:15:00.000 --> 00:15:08.000 Number 2 I mentioned hand. weeding and i'll say it again. Go out there, and especially in those heavy pockets in the field. 00:15:08.000 --> 00:15:15.000 Go out and get those number 3 there's a few people that are using the weed. 00:15:15.000 --> 00:15:31.000 Zapper. We just saw some published information from missouri where they're telling us that the weed Zapper not only fries the plant, but it is also reducing the vability of the seed that's in the process of being 00:15:31.000 --> 00:15:38.000 made by the plant, and and then you mentioned a good one and I'm not gonna let that one go away. 00:15:38.000 --> 00:15:49.000 Getting good maps, especially at harvest as to where the most severe weed infestations are in fields makes a lot of sense to me. 00:15:49.000 --> 00:16:02.000 Yeah, that's. one thing that we've asked about it like our private has a site applicator recertification workshops in the in the past, and it's it's kind of surprising how few people actually report using 00:16:02.000 --> 00:16:05.000 weed maps, but I mean I think that's a could be very useful. 00:16:05.000 --> 00:16:09.000 Don't you think just to help target what products you should be using in areas. 00:16:09.000 --> 00:16:15.000 Maybe you need to find between rates for example or where you're gonna really try to hit it hard. 00:16:15.000 --> 00:16:20.000 I just seems like a kind of underutilized tool. 00:16:20.000 --> 00:16:28.000 Always like to say that we know exactly where the weeds are until we harvest, and then we do tillage and our. 00:16:28.000 --> 00:16:36.000 You know we have this big empty field again and we're not exactly sure where those weed areas were 00:16:36.000 --> 00:16:43.000 Our software products now are so good at at giving us location. 00:16:43.000 --> 00:16:50.000 Specific information. Take advantage of that, and draw some maps, and those those are records just as valuables. 00:16:50.000 --> 00:16:57.000 The yield maps, in my opinion. Well, and and one last question before we switched over on the insect end. 00:16:57.000 --> 00:17:10.000 But so if i'm a far away, you know and we're getting close to harvest, and I see this kind of water have forest coming up, Should I just run my combine right through there, or come come back later and and I think 00:17:10.000 --> 00:17:17.000 we know the answer to this, but yeah I i'd prefer that First of all, i'd say wait as long as you can with that field. 00:17:17.000 --> 00:17:28.000 Do the the fields that have less pressure first, and then if you can go around those areas with with heavy weeds 00:17:28.000 --> 00:17:35.000 In many cases you're compromising yield there anyway, especially in the most severe areas. 00:17:35.000 --> 00:17:48.000 But our combines do a tremendous job of spreading that seat out, and I would. I would prefer that we don't allow that to happen, or if we do, do, that, let's do it at the end. 00:17:48.000 --> 00:17:52.000 And make sure we're cleaning our equipment when we're done. 00:17:52.000 --> 00:17:57.000 Excellent points. Thank you, Tom. claire i'm gonna turn it over to you. 00:17:57.000 --> 00:18:03.000 Yeah. And I wonder if we do wanna address the question in the Q. A. 00:18:03.000 --> 00:18:07.000 Quickly, just because other people may be curious to Tim. 00:18:07.000 --> 00:18:15.000 Can people submit waterhead or gray weed samples that they believe have ppo and glyphosate resistance? 00:18:15.000 --> 00:18:18.000 And if so, can you kind of tell them how to do that? 00:18:18.000 --> 00:18:37.000 Yes, you can. So what I would encourage you to do is to reach out to your regional educator or county agent, and we'll be sure either our educators or agents are in contact with myself. 00:18:37.000 --> 00:18:42.000 Or Dr. Dublin syringe, my colleague at the University of Minnesota. 00:18:42.000 --> 00:18:59.000 So Dublin especially is taking a lead at trying to map out where weed infestations are especially resistant weeds, and he'd love to hit Devlin and his team would love to get those samples. 00:18:59.000 --> 00:19:05.000 Thank you. Thanks. Yeah. So now we will transition over to our insect topic. 00:19:05.000 --> 00:19:14.000 So we're going to hear from Bruce Potter our Integrated Test management specialist at the Southwest Research and Outreach Center in Lambertton. 00:19:14.000 --> 00:19:17.000 Thanks for joining us, Bruce and Diana. 00:19:17.000 --> 00:19:24.000 If we could launch our poll we'll start off with our insect Poll here. So we're asking about Soybean aid. 00:19:24.000 --> 00:19:27.000 So how do you decide when to spray for Soy being aphids? 00:19:27.000 --> 00:19:31.000 And you can select all that apply and our options are. 00:19:31.000 --> 00:19:40.000 You use the economic threshold? you believe 258 fence per plant threshold is too high. 00:19:40.000 --> 00:19:53.000 You spray When custom applicators are in the area you don't scout us spray when your neighbors do he spray a fence as a tank, mix and herbicide or fung aside you spray once the 00:19:53.000 --> 00:20:15.000 soybeans reach a particular growth stage or around a particular calendar date, or you spray when you're agronomist or crop consultant tells you, too. There's 2 more options Yeah, so to the scroll everybody and you 00:20:15.000 --> 00:20:20.000 do not spray and thensect aside for so I mean if it control at all, or you don't plant. 00:20:20.000 --> 00:20:29.000 So I being class you don't farm 00:20:29.000 --> 00:20:43.000 I'll just give a couple more seconds here 00:20:43.000 --> 00:20:47.000 Alright, Diane, I think you can. Yep. Thank you. 00:20:47.000 --> 00:21:00.000 Share the results. So we see that the largest number here, 52% of our participants today use the economic threshold, and then kind of our second largest number. 00:21:00.000 --> 00:21:09.000 We see 14% believe that the threshold of 250, if it's per plant, is too high, so they spray earlier. 00:21:09.000 --> 00:21:20.000 So first of this, there's anything else you want to point out and the results or comment on that 00:21:20.000 --> 00:21:23.000 I'd like to talk about a little bit of spring 00:21:23.000 --> 00:21:26.000 If is a take mix with an herbicide or funds aside. 00:21:26.000 --> 00:21:32.000 And then people, I think that 250, if it per plant threshold is too high. 00:21:32.000 --> 00:21:41.000 You know it. Car crop prices are high this year, and people haven't had there's pretty many aphasis for the past couple of years. 00:21:41.000 --> 00:21:51.000 Populations are a little bit up this year. and and you know, I suppose people have been waiting for a couple of years wanting to kill Aids, and now is their chance. 00:21:51.000 --> 00:21:56.000 And I think this cai crop rice. Why, 00:21:56.000 --> 00:22:09.000 Falls into things, too, in that you know they're worried they're gonna lose yield these aphids have no idea what how much you're gonna get from bushel It's not that they eat more when 00:22:09.000 --> 00:22:13.000 prices are high and they eat less when the prices are low. 00:22:13.000 --> 00:22:20.000 That that 258, and per plant threshold is pretty darn and conservative, has been for a long time. 00:22:20.000 --> 00:22:28.000 It gives you some some opportunity to like the time in there to get things. 00:22:28.000 --> 00:22:38.000 Those populations controlled so I know there's a lot of fear, and and angst about not getting things sprayed in time. 00:22:38.000 --> 00:22:45.000 But you know I don't I don't think it's. I don't know the threshold is not is not too too high. 00:22:45.000 --> 00:22:49.000 It's maybe people's perception of how much time they have to get things done. 00:22:49.000 --> 00:22:58.000 Those sorts of things i've heard people this year worried about without Lars van wanting to use a ground rig, and they want to spray away. 00:22:58.000 --> 00:23:06.000 That canopies open. guys want to mix it with a fungus side and and save a a trip. 00:23:06.000 --> 00:23:14.000 The problem with that is and you know most fungi size for sprayed a week 2 weeks ago. 00:23:14.000 --> 00:23:25.000 Right Now we're right in the middle of a of If it's moving between fields we're getting if it's as these big plants quit growing vegetatively, we got a lot of those events that 00:23:25.000 --> 00:23:40.000 were up on the top of the plan those producing wing nimps. Those are winged wing defense. Those acids are dispersing within the field throughout fields, and you know that insecticide's gone by now or a 00:23:40.000 --> 00:23:50.000 lot of it's gone. so your timing timing issue might be a little bit of a a problem. if you're doing a tank tank mix just like spring corn worm beetles with corn 00:23:50.000 --> 00:24:03.000 fungicides. So the other thing that happens if you're spring and insecticide and the fungi side without regard for how many insects you've got out there is you are knocking 00:24:03.000 --> 00:24:14.000 out both, possibly some beneficial fungi and some insect predators, and as as if it's moved into the field, flaring Athens or flaring spider mice. 00:24:14.000 --> 00:24:21.000 If if you've got some hot dry weather 00:24:21.000 --> 00:24:27.000 So don't do it Well, that kind of leads into a question from a participant. 00:24:27.000 --> 00:24:33.000 Here is I've been waiting on I started being fun just side application. as long as it felt I could with the goal. 00:24:33.000 --> 00:24:38.000 If needed, I would tink, mix, and set aside with that application. 00:24:38.000 --> 00:24:48.000 Is there a problem with that? Well, I mean if if if you're waiting in and waiting till you have aence. 00:24:48.000 --> 00:25:00.000 There's not a problem. and if you're but if you're gonna throw the ins if you don't have a I I think you could save a little money and and some potential risk by keeping the 00:25:00.000 --> 00:25:06.000 insecticide out of it. so you've got some time on the fungi side. 00:25:06.000 --> 00:25:14.000 Especially if you're in one of these drier areas there's not much there hasn't been much phone to leaf disease out there. 00:25:14.000 --> 00:25:19.000 So there's no reason to be real proactive if you've got a weight weight mold in the field. 00:25:19.000 --> 00:25:26.000 You're trying to manage those sorts of things and Then You'd want to have that bunch of site on a lot earlier. 00:25:26.000 --> 00:25:41.000 Thanks. Yeah. And and back to this sorry being a vid application or with the threshold of 250 aprons per plant on 80% of the plans and a typical year that gives you about a a week. 00:25:41.000 --> 00:25:48.000 To react. right, Bruce. And so with high prices this year, maybe that windows a little bit shorter. 00:25:48.000 --> 00:26:00.000 No, it's not the th the the timing still about the same. because it's not that that 250 acids per plant causes yield loss immediately. 00:26:00.000 --> 00:26:08.000 The those if it have to feed on the plant for a while it's a concept of 8 for days, or how many if it's you have for how long? 00:26:08.000 --> 00:26:16.000 So There's there's there's a there's a leg in there, and we don't have real good data on this further along. 00:26:16.000 --> 00:26:22.000 Those plants get into as far as Further along. 00:26:22.000 --> 00:26:27.000 Those plants are in development, probably the more aphid they can tolerate. 00:26:27.000 --> 00:26:33.000 So bigger more mature plans can probably take little North Pacific. 00:26:33.000 --> 00:26:38.000 It, feeding them to a small early reproduction like this stage plan. 00:26:38.000 --> 00:26:42.000 One thing I want to mention on these if it's in 250. 00:26:42.000 --> 00:26:49.000 Some guys may think they've gotten burned by waiting till 250, and the problem might not be the threshold. 00:26:49.000 --> 00:26:55.000 It might be Scott scouting. I mentioned a lot of aphids have left the field right now. 00:26:55.000 --> 00:27:09.000 But they've left some if it's below in the lower canopy, and over the last week some of those small white aviation they leave behind have been reproducing real well one day I was looking at stuff 00:27:09.000 --> 00:27:16.000 we'd skeleton last week and some of these adult is, if it's in the lower canopy head up to 12. 00:27:16.000 --> 00:27:21.000 Well, Nms to him, so those populations can can really explode lower in the canopy. 00:27:21.000 --> 00:27:30.000 Those acids are smaller down there and they're hard at the spot. so make sure if you're scouting you're not just looking at the top of the plant anymore. 00:27:30.000 --> 00:27:38.000 You've got to look at. Look further down yeah good suggestion We have a question about spider mites. 00:27:38.000 --> 00:27:52.000 How are the population so far this year we're just starting to see some some injury levels in the The past week in these more droughty areas or past couple of weeks in the drought the areas pretty 00:27:52.000 --> 00:27:59.000 isolated even in some of the draw stressed areas of spider mice have been pretty low. 00:27:59.000 --> 00:28:06.000 And now we've had some rain and some dues some cooler weather that should tamp the spider might down. 00:28:06.000 --> 00:28:15.000 But there's plenty of time if you have things heat up, and and you run short of moisture again for those populations to to pop back up. 00:28:15.000 --> 00:28:21.000 But the rain really, and the weather is probably helping us out right now. 00:28:21.000 --> 00:28:25.000 Kind of going back to Evans, because I just saw this question pop up. 00:28:25.000 --> 00:28:28.000 But could you make some generalizations about the aid? 00:28:28.000 --> 00:28:34.000 Populations like kind of across the States over all this year. 00:28:34.000 --> 00:28:40.000 There. Athens are like a lot of insect problems or insects. 00:28:40.000 --> 00:28:43.000 We have this year whether it was army worms, cutworms. 00:28:43.000 --> 00:28:52.000 Grasshoppers. spider mites they're there, but they're spotty they're not real uniform. 00:28:52.000 --> 00:28:57.000 And so initially, it was a lot of these small fields, the block surrounded by trees. 00:28:57.000 --> 00:29:07.000 Some of those got treated. Minnesota River valley, and and you know, is in and and into the south central part of the State. 00:29:07.000 --> 00:29:14.000 We've got some higher populations but again. it's still mostly smaller fields. at Lambertton. 00:29:14.000 --> 00:29:18.000 Here we're pretty close to threshold but then you go a little bit. 00:29:18.000 --> 00:29:25.000 A few fields away some of the larger fields, and you know, or either pretty rare, or still out low population. 00:29:25.000 --> 00:29:38.000 So they're there. but I've heard of issues up into West Central Minnesota as well, but it seems like they're still It's not like the early days of Aphans. 00:29:38.000 --> 00:29:42.000 Were we'd have these big waves of aid infestations moving through the State. 00:29:42.000 --> 00:29:57.000 They're still they're still pretty scattered do you have any information, Bruce and if any of these populations kind of that, you're seeing across the State are looking like they might have some resistance to pi rays and you know that's been 00:29:57.000 --> 00:30:02.000 kind of on our minds. the last couple of years is seeing some resistant populations. 00:30:02.000 --> 00:30:08.000 So i'm assuming they are they have they haven't it hasn't gotten any less. 00:30:08.000 --> 00:30:19.000 We still they'll pick them. up in a research boss or or when people people try a breath rate, there's still some fields that have issues it's not every field by any means. 00:30:19.000 --> 00:30:27.000 But it's a large enough percentage of them that spring a straight breathe rights. pretty risky 00:30:27.000 --> 00:30:35.000 We'll see what happens this year but my guess is it's it's it's stick it's fixed in the population. 00:30:35.000 --> 00:30:45.000 What do you recommend for people If they suspect that they might have a resistant population or a past of that 00:30:45.000 --> 00:30:52.000 And now that clerk or peer passes out of the picture, apparently, what what do you think people should do? 00:30:52.000 --> 00:30:58.000 We've got we've got some alternatives. It's a lot better situation than with spider mice. 00:30:58.000 --> 00:31:06.000 We've got some alternatives we've got some group for insecticide savanto and transform. 00:31:06.000 --> 00:31:11.000 We've got Sophia. those 3 are all pretty specific to sucking insects. 00:31:11.000 --> 00:31:14.000 They do a good job on efforts. You need good coverage just like you do. 00:31:14.000 --> 00:31:20.000 The perthoids they're translocated to a to a certain extent, so it so. 00:31:20.000 --> 00:31:28.000 But we've had pretty good results in in field and fields, and especially in our insecticide studies. 00:31:28.000 --> 00:31:40.000 So those are an option if you use a breath right You're probably gonna have to mix it with a neo-naick at next annoyed or you're gonna have to mix it with one of these other 00:31:40.000 --> 00:31:56.000 products. There's some repackage things like rich back which has got transformed in it in a freezroid or or Renaissance, which is Sophia, with with the breath right the reason for the truth right 00:31:56.000 --> 00:32:00.000 is to broaden the spectrum out. you know. 00:32:00.000 --> 00:32:03.000 For some reason people are all confused when they spray if it's. 00:32:03.000 --> 00:32:09.000 If the efforts are dead, they don't want to see grass stoppers, or anything else out there. 00:32:09.000 --> 00:32:15.000 You know I guess I guess i'd i'd be more focused on trying to take care of the pop problem at hand. 00:32:15.000 --> 00:32:18.000 You've got a few grasshoppers but if it's so. 00:32:18.000 --> 00:32:24.000 Your problem worried about the Athens. you don't have to worry about killing a few with grasshoppers out there. 00:32:24.000 --> 00:32:32.000 Business need to eat, too. Thanks for saying I know we're running cool, Since is there anything you wanna add quick here? 00:32:32.000 --> 00:32:50.000 Clear they're running near the end I know we But just that we did put in the chat a link to some information on insecticide options, for so I didn't do especially with hybrid ride resistance on the horizon, so that is in 00:32:50.000 --> 00:32:57.000 the links, and I guess I just say any last part in thoughts from you, Bruce. 00:32:57.000 --> 00:33:03.000 No, I think, scouting is important here we're gonna be looking at some defoliation fully eating insects. 00:33:03.000 --> 00:33:07.000 Later on corn wrote rooms if you're in on the corn side. 00:33:07.000 --> 00:33:20.000 Corn room. rooms are are still the issue skeleton was, feels, and and know what you're what you're dealing with, as far as resistance and populations for next year. 00:33:20.000 --> 00:33:24.000 Alright. Well, thank you, Bruce and Tom. Thank you as well. 00:33:24.000 --> 00:33:29.000 Appreciate both of you participating in everybody who joined us today. 00:33:29.000 --> 00:33:40.000 And again, just a reminder we do have a short very short 4 question survey that we'll have again as you leave this session, and part of that is just seeing what you'd like to talk about next week we have just 00:33:40.000 --> 00:33:43.000 2 weeks left of the strategic farming field notes. program. 00:33:43.000 --> 00:33:47.000 So on the seventeenth I believe we'll be looking at Palmer. 00:33:47.000 --> 00:33:57.000 Amaranth is one of the topics, and then the last session on the 20 fourth, likely hitting on corn, Silas and forge topics and other issues as well. 00:33:57.000 --> 00:34:00.000 But do you wanna put in a quick. We have a couple of field days coming up. 00:34:00.000 --> 00:34:05.000 We got the cover prop field date, August the eighteenth of the Southwest Research and Outreach Center, by Lambertton. 00:34:05.000 --> 00:34:12.000 Checking starts at 8 30. The program will go from 9 to one, and then the Pest management Field day that's August 30. 00:34:12.000 --> 00:34:17.000 First at the Southwest research and outreach center in London. that's 8, 30 to 1230 versus, I think, at the time. 00:34:17.000 --> 00:34:25.000 Right on that. No good to see all kinds of death and destruction. There you go. So yeah, Thanks for sponsors. today. 00:34:25.000 --> 00:34:36.000 The Minnesota, slaving Research and Promotion Council and the Minnesota.
