00:00:03,080 --> 00:00:06,030
Welcome to the University of Minnesota as

2
00:00:06,030 --> 00:00:08,250
strategic farming field notes Program.

3
00:00:08,250 --> 00:00:10,440
I'm Anthony Hansen, Regional Extension Educator

4
00:00:10,440 --> 00:00:11,895
in integrated pest management.

5
00:00:11,895 --> 00:00:14,220
Support for this program is also provided by

6
00:00:14,220 --> 00:00:16,710
the Minnesota Corn Research and Promotion Council,

7
00:00:16,710 --> 00:00:18,120
as well as the Minnesota Soybean

8
00:00:18,120 --> 00:00:19,965
Research and Promotion Council.

9
00:00:19,965 --> 00:00:22,470
Unfortunately, recording for July 30th,

10
00:00:22,470 --> 00:00:24,120
2022 isn't available due

11
00:00:24,120 --> 00:00:25,995
to some technical issues that we had.

12
00:00:25,995 --> 00:00:27,720
So here's just a quick summary of what

13
00:00:27,720 --> 00:00:29,460
was covered at the webinar for that day.

14
00:00:29,460 --> 00:00:31,470
And we will have online postings

15
00:00:31,470 --> 00:00:33,600
on some of the text
and what we covered.

16
00:00:33,600 --> 00:00:36,600
To start off, we had Dr.
Jeff Coulter on to talk

17
00:00:36,600 --> 00:00:39,235
about what's going on
with corn pollination.

18
00:00:39,235 --> 00:00:41,195
A bit of a current
status update,

19
00:00:41,195 --> 00:00:42,380
and then also what might be

20
00:00:42,380 --> 00:00:43,520
happening in the coming weeks,

21
00:00:43,520 --> 00:00:45,800
especially junit overall been

22
00:00:45,800 --> 00:00:48,770
a pretty dry month
and fairly warm to

23
00:00:48,770 --> 00:00:51,470
to the point that we are
actually coming ahead

24
00:00:51,470 --> 00:00:54,425
of average on growing degree
days for corn so far.

25
00:00:54,425 --> 00:00:57,125
So some fields that
were planted on time,

26
00:00:57,125 --> 00:00:59,570
we're seeing pollination
occurring already or

27
00:00:59,570 --> 00:01:02,225
just starting to in about
the next week or so.

28
00:01:02,225 --> 00:01:03,860
But because of variability,

29
00:01:03,860 --> 00:01:05,090
we had to planting date.

30
00:01:05,090 --> 00:01:06,710
There are definitely some
fields that are going

31
00:01:06,710 --> 00:01:08,540
to be further
behind than others.

32
00:01:08,540 --> 00:01:10,580
But overall with
the temperatures

33
00:01:10,580 --> 00:01:12,425
were expected to see coming up,

34
00:01:12,425 --> 00:01:14,930
pollination should be rolling
along pretty well without

35
00:01:14,930 --> 00:01:17,870
any significant issues with
too much heat occurring,

36
00:01:17,870 --> 00:01:18,980
since we're going to be in about

37
00:01:18,980 --> 00:01:21,470
the lower nineties or
so, we are, however,

38
00:01:21,470 --> 00:01:23,270
starting to see some
drought conditions

39
00:01:23,270 --> 00:01:25,205
start to merge in some
areas of the state.

40
00:01:25,205 --> 00:01:27,530
And this could delay or affect

41
00:01:27,530 --> 00:01:29,015
pollination in terms of

42
00:01:29,015 --> 00:01:31,100
final yield that we
will see in the crop.

43
00:01:31,100 --> 00:01:32,360
So very much depends

44
00:01:32,360 --> 00:01:33,710
on what part of the
safe people are in

45
00:01:33,710 --> 00:01:34,850
and what their
fields are looking

46
00:01:34,850 --> 00:01:36,680
like for drought conditions.

47
00:01:36,680 --> 00:01:38,450
We also had Seth Ghibli with

48
00:01:38,450 --> 00:01:39,920
the Environmental
Protection Agency

49
00:01:39,920 --> 00:01:41,434
on to talk about atrazine.

50
00:01:41,434 --> 00:01:43,280
This is a broad
spectrum herbicide

51
00:01:43,280 --> 00:01:44,840
that is beginning
a look again in

52
00:01:44,840 --> 00:01:47,150
terms of water quality issues

53
00:01:47,150 --> 00:01:49,445
and potentially being
able to mitigate those.

54
00:01:49,445 --> 00:01:50,930
So currently the EPA is

55
00:01:50,930 --> 00:01:54,244
proposing some restrictions
to the use of atrazine,

56
00:01:54,244 --> 00:01:55,970
mostly to prevent run-off.

57
00:01:55,970 --> 00:01:59,120
So there is a 60 day
comment period open to

58
00:01:59,120 --> 00:02:02,915
the public that closes on
September 6th at 2022.

59
00:02:02,915 --> 00:02:04,790
So he suggested that if

60
00:02:04,790 --> 00:02:07,505
atrazine restrictions are
going to affect anyone,

61
00:02:07,505 --> 00:02:08,930
that they should check out

62
00:02:08,930 --> 00:02:11,240
the public comment period
and submit their comments so

63
00:02:11,240 --> 00:02:13,010
they can work them into

64
00:02:13,010 --> 00:02:15,755
any recommendations
that are coming out.

65
00:02:15,755 --> 00:02:18,425
And just as a quick final note,

66
00:02:18,425 --> 00:02:21,860
we are starting to see
some insect issues either

67
00:02:21,860 --> 00:02:24,170
continue across the state or

68
00:02:24,170 --> 00:02:26,630
starting to see some just
emerging a little bit.

69
00:02:26,630 --> 00:02:29,300
So first off, the big question
that comes up quite a

70
00:02:29,300 --> 00:02:32,270
bit around this time of
year is soybean aphid.

71
00:02:32,270 --> 00:02:33,980
And we are seeing some across

72
00:02:33,980 --> 00:02:35,780
the state infested and soybeans,

73
00:02:35,780 --> 00:02:38,495
but generally not
at high numbers.

74
00:02:38,495 --> 00:02:40,460
There are however,
a few pockets of

75
00:02:40,460 --> 00:02:42,980
the state where populations
are increasing.

76
00:02:42,980 --> 00:02:44,810
Now it's going to
be pretty early

77
00:02:44,810 --> 00:02:46,655
to be treating for
soybean aphid,

78
00:02:46,655 --> 00:02:49,040
but keep an eye on those
populations as they start

79
00:02:49,040 --> 00:02:51,995
to grow more in later July.

80
00:02:51,995 --> 00:02:54,230
Alfalfa weevil has also been

81
00:02:54,230 --> 00:02:56,615
a concern for some
growers across the state,

82
00:02:56,615 --> 00:02:58,790
especially around
Central Minnesota.

83
00:02:58,790 --> 00:03:00,620
Now some growers
have seen damage,

84
00:03:00,620 --> 00:03:02,210
especially in their
first and sometimes

85
00:03:02,210 --> 00:03:04,100
second cutting alfalfa weevil.

86
00:03:04,100 --> 00:03:07,010
But if you are considering
an application now,

87
00:03:07,010 --> 00:03:08,930
be sure to actually go
out and check the field

88
00:03:08,930 --> 00:03:10,940
that the alfalfa weevil
is still present.

89
00:03:10,940 --> 00:03:13,205
Larvae can cause
damage in the field,

90
00:03:13,205 --> 00:03:16,070
but adults are going
to be dormant this

91
00:03:16,070 --> 00:03:17,450
time of year and
they're not feeding

92
00:03:17,450 --> 00:03:19,310
are causing significant
damage either.

93
00:03:19,310 --> 00:03:20,915
Now normally this
time of year you're

94
00:03:20,915 --> 00:03:22,685
only going to find adults.

95
00:03:22,685 --> 00:03:24,560
You're usually not going
to be concerned about

96
00:03:24,560 --> 00:03:27,410
alfalfa weevil or treating
for it any further.

97
00:03:27,410 --> 00:03:29,945
However, there have
been some reports

98
00:03:29,945 --> 00:03:32,090
and parts of the state
that growers are

99
00:03:32,090 --> 00:03:34,685
finding very early instar larvae

100
00:03:34,685 --> 00:03:36,890
are very young ones that
have been laid recently.

101
00:03:36,890 --> 00:03:40,355
Well, that's not typical for
what we see with that past.

102
00:03:40,355 --> 00:03:42,440
But there may be some issues

103
00:03:42,440 --> 00:03:43,820
with either new strains coming

104
00:03:43,820 --> 00:03:45,950
in or some other
environmental conditions

105
00:03:45,950 --> 00:03:48,320
that a delayed
emergence of this one.

106
00:03:48,320 --> 00:03:50,600
So just be sure to go
out there and Sculpt.

107
00:03:50,600 --> 00:03:52,130
If you do find larvae,

108
00:03:52,130 --> 00:03:53,510
check that they're actually at

109
00:03:53,510 --> 00:03:55,970
threshold levels because you
don't want to be spraying

110
00:03:55,970 --> 00:03:58,220
when that species is

111
00:03:58,220 --> 00:04:00,050
on its way out for
the season instead,

112
00:04:00,050 --> 00:04:01,280
and you're not
getting a return on

113
00:04:01,280 --> 00:04:03,005
investment of the insecticide.

114
00:04:03,005 --> 00:04:06,500
And also just a general
reminder that court purify us.

115
00:04:06,500 --> 00:04:08,555
We've had questions
about that as well.

116
00:04:08,555 --> 00:04:11,195
It is not allowed for
any agricultural use,

117
00:04:11,195 --> 00:04:13,895
even if you did have it on
hand for a previous year.

118
00:04:13,895 --> 00:04:15,080
This is definitely come up a few

119
00:04:15,080 --> 00:04:16,760
times and questions
that I've gotten.

120
00:04:16,760 --> 00:04:18,725
So whether it's
alfalfa weevil or

121
00:04:18,725 --> 00:04:21,620
upcoming applications
potentially for soybean aphid.

122
00:04:21,620 --> 00:04:23,180
Be sure that you're following

123
00:04:23,180 --> 00:04:25,130
current Pesticide Regulations.

124
00:04:25,130 --> 00:04:26,660
Avoid ones that are no longer

125
00:04:26,660 --> 00:04:28,355
allowed such as core pure PFOS,

126
00:04:28,355 --> 00:04:29,900
but then also double-check
and the label

127
00:04:29,900 --> 00:04:31,760
that it's actually approved

128
00:04:31,760 --> 00:04:34,025
for application on that crop

129
00:04:34,025 --> 00:04:37,205
because of field school on the
St. Paul campus next week,

130
00:04:37,205 --> 00:04:38,450
our next episode of

131
00:04:38,450 --> 00:04:41,600
field notes will be
on the 27th of July.

132
00:04:41,600 --> 00:04:43,430
So stay tuned for that episode

133
00:04:43,430 --> 00:04:46,230
and we'll see you
in about two weeks.
