Radiant® SC Insecticide: IPM Rotation Cornerstone for Vegetable GrowersUnique Group 5 chemistry effectively controls costly pests

INDIANAPOLIS — Vegetable growers who understand the importance of rotating insecticides as part of their Integrated Pest Management (IPM) program to effectively control damaging pests continue to rely on Radiant® SC insecticide. The unique chemistry of Radiant makes it the ideal foundation for grower IPM programs.
Classified as a Group 5 insecticide by the Insecticide Resistance Action Committee (IRAC), Radiant is frequently used to reduce initial populations of many tough-to-control insects — including thrips, loopers, armyworms, leafminers and spotted wing drosophila — and then rotated with another class of chemistry for additional follow-up applications if necessary.
“It doesn’t take long for resistance to develop, especially if growers don’t rotate chemistries,” says Christy Hoepting, Extension vegetable specialist with Cornell University, Albion, New York. “Radiant remains an important cornerstone of an effective IPM program and is an insecticide we rely on. It is highly effective at controlling a variety of pests, especially onion thrips in onions. The role it plays as an IPM rotation partner cannot be overemphasized.”
Hoepting encourages growers to rotate Radiant with other classes of chemistry to help ensure all products retain their effectiveness.
“Growers should rotate between groups of products, not within,” she says. “Unlike other insecticides, Radiant is effective during the latter half of the growing season when onion thrips pressure is at its highest and it effectively controls both larvae and adults. The short PHI of Radiant allows growers to use it closer to harvest when other products can no longer be used. The translaminar activity of Radiant is also advantageous because it controls targeted insects outside of the direct line of spray.”
Preserves natural enemies, too
Preserving natural enemies (beneficials) also is an important component of an effective grower IPM program. The selective nature of Radiant® SC insecticide as a unique Group 5 chemistry helps preserve key natural enemies while providing effective control of unwanted pests.
“The importance of maintaining beneficial insects can sometimes take a back seat for the more obvious priority of controlling the costly and damaging ones,” says Kevin Sheaffer, insecticide product manager with Dow AgroSciences. “Radiant helps preserve populations of natural enemies that are so important to a total IPM program. Growers also like the quick knockdown and long residual.”
The four-hour field re-entry and short preharvest interval (PHI) of Radiant is another advantage.
“Late-season infestations can be particularly impactful on yield and profitability,” Hoepting says. We put tremendous emphasis on preserving the useful life of this most effective product.”
