How Delegate ® WG insecticide is
an essential tool for potato growers
It is estimated that of the 37% of all crops lost to
pests, 13% are lost to insects. When it comes to potato
production, aphids, the Colorado beetle and the potato
tuber moth are the most damaging insects causing
widespread yield loss.
The foliar-feeding Colorado potato beetle can defoliate
potato plants leading to yield reductions of around 30-50
percent. It is also recognized to develop resistance over
short periods of time. Crop advisors have, for some time
now, been encouraging growers to diversify their mode-ofaction
selection of insecticides to prolong the efficacy of
existing chemistries.
One novel insecticide continuing to deliver control over
a broad spectrum of key pests limiting potato yields and
grower profitability is Delegate® WG insecticide with
Jemvelva™ active from Corteva Agriscience.
Using an innovative mode of action to control damaging
pests, Delegate® WG insecticide is an essential tool for
growers producing pome fruits, stone fruits, cranberries,
bushberries, caneberries and, of course, potatoes.
Kevin Cochrane, territory manager for Corteva
Agriscience, has worked with potatoes and other crops for 15
years. Cochrane's main focus is working with growers to help
grow quality crops by using Corteva Agriscience fungicides,
insecticides, herbicides, nematicides, and biologicals.
" Scouting for pests, both internally and externally, is the
best way to stop pests early before their counts escalate
into large infestations. Early control can lead to healthier
and more resilient potato crops. I advise the growers I work
with to review our complete portfolio of potato product
solutions, " Cochrane said. " Tracking soil temperatures and
giving growers bi-weekly advice is also helpful. "
According to Corteva Agriscience, Delegate WG
insecticide delivers a unique mode of action to control
a variety of pests including, Colorado potato beetle,
armyworms, leafrollers, leafminers, thrips and more, all
while minimizing the impact on beneficial insects. It also
offers growers harvest flexibility - a convenient, four-hour
re-entry interval and pre-harvest intervals as short as seven
days in potatoes.
Key benefits and features of Delegate WG
insecticide include:
* Control of a broad-spectrum of numerous pests.
* Maintains populations of most beneficial insects.
* A four-hour re-entry interval.
* Acceptance for registration under the U.S.
Environmental Protection Agency's Reduced Risk
Pesticide Initiative.
* A featured main ingredient, spinetoram, which is
classified as a Group 5 insecticide, making it an ideal
choice for Insecticide Resistance Management (IRM).
" First and foremost, Delegate WG insecticide delivers
efficacy over many insect pests. You can combat worm
species, chewing pests, the Colorado potato beetle, thrips
and more, " Cochrane said. " It's also very soft on pollinators
when not directly contacted. Delegate WG insecticide fits
well into Integrated Pest Management (IPM) systems and
supports resistance management stewardship. "
According to Cochrane, Delegate WG insecticide can be
applied by ground, air or chemigation - adding increased
flexibility to a potato grower's busy production schedule.
" Delegate WG insecticide has quick knockdown
and delivers extended residual control to mitigate reinfestations, "
Cochrane said.
