CROP PROTECTION GUIDE
SAID THE COLORADO POTATO BEETLE TO THE WIREWORM.
Control the two toughest pests in potatoes.
Already renowned for providing true wireworm control in-furrow, Cimegra® insecticide is now registered for foliar use on Colorado potato beetles. Powered by the unique IRAC Group 30 mode of action, it provides rapid knockdown and control you can count on. And Cimegra works through both contact and ingestion. In other words, the only thing chewing pests end up biting is the dust. Visit agsolutions.ca/Cimegra to learn more.
