Supporters of isocycloseram said it could help with a pest that’s long shown resistance to insecticides. Russ Groves, an entomology professor and Extension specialist at the University of Wisconsin-Madison, said the insecticide has been evaluated in Wisconsin to gauge its effectiveness at controlling the Colorado potato beetle. The pest eats the leaves off potato plants, resulting in serious yield losses.
“We’ve evaluated this tool alongside others, and we see that it’s a very good fit,” Groves said. “It performs well in controlling the insect.”
