Controlling Unwanted Pests
How Delegate® WG insecticide is an essential tool for potato growers
(Sponsored) It is estimated that of the 37 percent of all crops lost to pests, 13 percent 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-of-action 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.
- Little if any impact on 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 herbicide has quick knockdown and delivers extended residual control to mitigate re-infestations,” Cochrane said.
