PROTECTING POTATO YIELDS
Combating pest infestations with innovative solutions
Approximately 37% of all crops are lost to agricultural pests
with 13% of these losses due to insects. In potato production,
some of the most damaging insects include aphids, the
Colorado potato beetle and the potato tuber moth, which
collectively lead to widespread yield losses.
The Colorado potato beetle (CPB), in particular, poses a
severe threat. This foliar-feeding insect can defoliate potato
plants, resulting in yield loss from 40-80%. Compounding the
issue is the beetle's ability to quickly develop resistance to
insecticides. As a result, crop advisers have long advocated for
growers to expand their mode-of-action selection to maintain
the effectiveness of existing chemistries.
One solution continuing to provide robust control over a broad
spectrum of key pests affecting potato yields and grower
profitability is Delegate®
WG insecticide with Jemvelva™
active
from Corteva Agriscience. This fast-acting insecticide utilizes a
unique mode of action to target and control damaging pests,
making it an indispensable tool for growers of pome fruits, stone
fruits, cranberries, bushberries, caneberries and potatoes.
With 15 years of agricultural production experience in
potatoes and other crops, Kevin Cochrane, territory manager
for Corteva Agriscience, assists growers in cultivating quality
crops by working with the growers to determine the best
solutions from the Corteva lineup of fungicides, insecticides,
herbicides and biological products.
" The Colorado potato beetle (CPB) has always been a
destructive pest that causes widespread economic damage in
potato production across the country, " Cochrane said.
" Particularly, in the Pacific Northwest over the last five to seven
years, we have seen an increase in CPB populations, and that
is very concerning to our growers. "
CPB is a significant pest known throughout North America.
Adults often become active in the spring - around the same
time as potato plants begin to emerge. Larvae and adults feed
on leaves and can defoliate plants completely.
Potato growers can combat CPB by using Delegate®
insecticide. Cochrane says, there isn't another Group 5 on the

Quick Facts
Delegate® WG insecticide:
Is a distinct mode of action (spinetoram) that fights insect
resistance
Is the only Insecticide Resistance Action Committee
(IRAC) Group 5 insecticide
Protects potatoes against costly crop losses
from insects
Has minimal impact on beneficial insects
Delivers fast knockdown
Controls CPB, armyworms, leafminers, leafrollers, thrips
and more
Offers, for flexible harvesting, a four-hour reentry interval
and preharvest intervals as short as seven days in
potatoes
Delegate WG is a significant advancement in pest
management, offering a reliable solution to protect potato yields
and marketability potential against losses from key pests while
protecting against the development of insecticide resistance.
Delegate WG also minimizes impact on beneficial insect
populations and prevents secondary pest outbreaks. Unlike
other product classes, such as neonicotinoids, and pyrethroids,
Delegate WG uses a unique mode of action to target the
insect's nervous system.
" We all have to work together to control pests like the
Colorado potato beetle, " Cochrane said. " If we don't, we may
find a day when it becomes even more difficult to control and
then growers will be left with fewer options. We have to work
with our growers to rotate modes of action, which will help
preserve efficacy of our products for the long term. "
