INSECT CONTROL
TABLE 2-18. INSECT CONTROL FOR POTATO, IRISH (CONT'D)
Insecticide, Mode of Action Code,
and Formulation
COLORADO POTATO BEETLE (cont'd)
cyantraniliprole, MOA 28
(Verimark) 1.67 SC
Amount of
Formulation
Per Acre
Restricted
Entry Interval
(REI)
4 hr
6.75 to 13.5 fl oz
Pre harvest
Interval (PHI)
(Days)
NA
Precautions and Remarks
Apply in-furrow at planting. Do not apply any other MOA Group 28 insecticide
for Colorado potato beetle control following an at-plant application for
cyantraniliprole. When applied at 10 to 13.5 fluid ounces per acre will provide
control of European corn borer in most years, except possibly in very early
planted potatoes.
dinotefuran, MOA 4A
(Venom) 70 SG
12 hrs
1 to 1.5 oz (foliar)
6.5 to 7.5 oz (soil)
imidacloprid, MOA 4A
Seed Piece treatment
(Genesis) 240 g/L
7
Soil treatment for preplant, preemergence, or ground crack application only.
To minimize selection for resistance, do not use foliar applications of any
IRAC MOA class 4A insecticides if any IRAC MOA class 4A insecticides
were applied to the crop as soil or seed piece treatments. See comments on
insecticide rotation under Colorado potato beetle.
0.4 to 0.6 fl oz/
100 lb of seed
tubers
Resistance has been reported and may reduce efficacy or duration of
control. To minimize selection for resistance, do not use foliar applications
of any IRAC MOA class 4A insecticides if any of these compounds were
applied to the crop as soil or seed piece treatments. See label for specific
instructions. For early-planted potatoes, control may be marginal because of
the prolonged time between application and Colorado potato beetle emergence.
Limit use to locations where Colorado potato beetles were a problem
in the same or adjacent fields during the previous year. Do not apply other
IRAC MOA class 4A insecticides to a field if seed pieces were treated with
Genesis. See product label for restrictions on rotational crops.
imidacloprid, MOA 4A
Soil treatment
(Admire Pro) 4.6F
(various) 2.0 F
12 hrs
0.74 fl oz/
1,000 ft row
-
Resistance has been reported and may reduce efficacy or duration of
control. See comments on insecticide rotation under Colorado potato beetle.
Admire Pro applied in-furrow at planting time may provide season-long control.
However, for early planted potatoes control may be marginal due to the
prolonged time between application and Colorado potato beetle emergence.
Use only in potato fields that have a history of potato beetle infestations. If
potatoes are rotated to a field adjacent to one planted in potato last year,
a barrier treatment may be effective. Admire Pro may also be applied as a
seed treatment. Check label for instructions regarding this use. Check label
for restrictions on planting crops following Admire Pro treated potatoes.
There have been reports of low levels of resistance to imidacloprid. To minimize
selection for resistance, do not use foliar applications of any IRAC MOA
class 4A insecticides if any of these compounds were applied to the crop as
soil or seed piece treatments. See comments on insecticide rotation under
Colorado potato beetle.
Foliar treatment
(Admire Pro) 4.6
(various) 1.6 F
12 hrs
1.3 fl oz
3.75 fl oz
7
Resistance has been reported and may reduce efficacy or duration of control.
To minimize selection for resistance, do not use foliar applications of any
IRAC MOA class 4A insecticides if any of these compounds were applied to
the crop as soil or seed piece treatments. See comments on insecticide rotation
under Colorado potato beetle. Apply when most of the egg masses have
hatched and most larvae are small (1/8 to 3/16 in.). An additional application
should be made only if defoliation increases. Allow at least 7 days between
foliar applications. Do not exceed 5.6 fluid ounces of Admire Proper field per
acre per season. Regardless of formulation, do NOT apply more than a total
of 0.31 lb imidacloprid per season. Foliar applications of imidacloprid should
not be applied If soil application was used.
imidacloprid, MOA 4A
+ cyfluthrin, MOA 3A premix
(Leverage) 2.7 SE
7
3 to 3.75 fl oz
There have been reports of low levels of resistance to imidacloprid. To minimize
selection for resistance, do not use foliar applications of any IRAC MOA
class 4A insecticides if any of these compounds were applied to the crop as
soil or seed piece treatments. See comments on insecticide rotation under
Colorado potato beetle, apply when most of the egg masses have hatched
and most larvae are small (1/8 to 3/16 inch). An additional application should
be made only if defoliation increases. Leverage will control European corn
borer if application coincides with egg hatch and presence of small corn
borer larvae. Leverage should not be used in fields treated with Admire Pro.
novaluron, MOA 15
(Rimon) 0.83 EC
12 hrs
9 to 12 fl oz
14
Novaluron is an insect growth regulator with activity against eggs and larvae.
Larvae are killed as they molt to the next stage. Eggs present at the time
of application are killed. Adults exposed produce few eggs. Novaluron is
most effective if directed against overwintered adults when egg numbers are
increasing, and small larvae are just beginning to appear. Do not apply to
successive generations of Colorado potato beetle. Do not apply more than
24 fl oz per season.
