Corteva Agriscience
Delegate WG Insecticide
Corteva Agriscience has received U.S. EPA and state approvals for Delegate WG insecticide in potatoes and sugarbeets. Labeled insects include Colorado potato beetle, potato psyllid, worms, thrips and leafminer.
Delegate contains the active ingredient spinetoram, a member of IRAC Group 5 (spinosyns). No other class of products — organophosphates, neonicotinoids or pyrethroids — affects the insect nervous system with the same mode of action. Delegate WG is similar in mode of action to Blackhawk insect control, a Corteva Agriscience product and also a member of IRAC Group 5. However, Delegate provides sharper control of insects.
Field trials with Delegate have been conducted on pests such as Colorado potato beetle and potato psyllid.
Delegate can be included in IPM programs that take advantage of beneficial insects. In fact, wide-scale use in other crops has shown Delegate to have low impact on populations of key beneficial insects. Delegate was originally registered under EPA’s Reduced Risk Pesticide Program.

PREV-AM
PREV-AM is a three-in-one insecticide, fungicide and miticide. It is a contact pesticide that can be applied throughout the season without danger of resistance buildup and is perfect for controlling pre-harvest insect and disease infestations. With a short REI and PHI, PREV-AM is a versatile alternative to conventional pesticides and is ideal for IPM and sustainable farming practices.
The desiccating properties of PREV-AM result in quick knockdown of insects and mites, typically within two to 24 hours. The water-repellent layer protecting most insects loses its effectiveness when contacted by a PREV-AM application. This allows the active ingredient to penetrate and destroy the soft, living tissues underneath. Insects and mites are then exposed to the loss of body fluids, causing death.
As a fungicide, the PREV-AM spray solution breaks down the protective membranes of the superficial fungal mycelia (hyphae) and spores, allowing the active ingredient to penetrate and destroy the living tissues underneath. This exposes the organism to the drying effect of the atmosphere and causes collapse within two to 24 hours. Plant tissue damaged by the fungus may also dry out and prevent further spread of infection, but healthy tissue is not affected at the recommended application rate.

Embrece-EA Surfactant
Embrece-EA is a unique blend of surfactants designed to elevate the performance of fungicides, insecticides and miticides by increasing wetting and spreading of spray materials.
Embrece-EA’s proprietary blend of nonionic surfactants (NIS) gives growers superior coverage and excellent wetting of their chosen spray material, meaning more product stays on the leaf surface, providing quicker absorption and improved control of the targeted pest. In addition to increased performance, Embrece-EA offers growers more safety and peace of mind while allowing for more application flexibility dependent on the crop grown. A lower use rate (1 pint per 100 gallons) is ideal for cover sprays, while higher use rates (1 quart 100 gallons) provides more penetration. The product also works well with difficult formulations, like soluble concentrates, and gives growers a safer alternative to similar adjuvants.
Embrece-EA is part of Wilbur-Ellis’s Eco Advantage line of products. Every Eco Advantage adjuvant is labeled for aquatic use, is made with ingredients for improved safety and handling, and is nonylphenol ethoxylates-free. Embrece-EA boasts lower phytotoxicity concerns than traditional adjuvants, as well as lower toxicity concerns for humans and the environment.
