New & Old InsecticidesNew & Old Insecticides Several “Reduced Risk” insecticides are under
development or were recently registered for vegetable insect pest control. But, do they work?
Are “Older Insecticides” still efficacious?
Are new insecticides better?

Pros: Cheaper than “In-the-Tank” mixtures Convenient for mixing and loading of the sprayer “New” product for the company with “old” a.i. Broad spectrum insect control
Cons: Confounds insecticide resistance management (IRM) Environmental exposure of a.i. when a pest is not present May not be more efficacious than one a.i. Takes tank mix decision away from PCA or grower
Older Worm Control InsecticidesOlder Worm Control Insecticides
“Newer is not always better”y Many older chemicals are still used safely,
effectively and some are “Reduced Risk” Several pyrethroid insecticides and Avaunt
insecticide are still efficacious Success and Proclaim are still an efficacious “Soft”
insecticides Intrepid 2 SC, Coragen, Synapse are some “newer”
vegetable worm control insecticides that are “Soft” “R d d Ri k”or “Reduced Risk”
Suggested Use Patterns for Older and New i id i blWorm Insecticides on Winter Vegetables
Stand Establishment is a critical time for worm control. Older insecticides (Avaunt, Lannate, OPs & Pyrethroids) New insecticides (Belt, Coragen, Durivo & Radiant)
Post thinning to head development is a time when more worm damage can be tolerated. Older insecticides (Intrepid Lannate Proclaim OPs & B t ) Older insecticides (Intrepid, Lannate, Proclaim, OPs & B.t.) New insecticides (Belt, Coragen, Voliam Flexi & Rimon)
Head development to harvest is a time when worm Head development to harvest is a time when worm control is critical. Older insecticides (Avaunt, Intrepid & Proclaim) New insecticides (Belt, Coragen, Voliam Xpress &
Radiant)
New & Old together for IPM and IRMNew & Old together for IPM and IRM
With older and newer insecticides together we have With older and newer insecticides together we have an arsenal of products that can be efficacious for vegetable pest management many years to come.
Vegetable IPM: Cultural control practices, along with proper sampling and timing of reduced risk insecticides, can be provide both efficacious and environmentally sound crop protection from insects.
Insecticide resistance management (IRM): With several chemical classes and MoA’s, insecticide resistance can be managed for years to comeresistance can be managed for years to come.
