Spotlight on the Cyazypyr® Mode of Action

Changing calcium use makes insects stop feeding quickly when exposed to products with Cyazypyr® insect control.

Calcium is a key component of muscle function. Disrupting how insects use calcium, allows products containing Cyazypyr® insect control to stop insect feeding almost immediately. Learn more about this mode of action and how crops are protected by Cyazypyr® activity.

Exirel® and Verimark® insect control are powered by Cyazypyr®. Rapid feeding cessation means vegetable and fruit crops are protected from insect damage, including physical damage and viruses spread by insects. The proven mode of action in these products help growers achieve abundant, beautiful harvests.


The PMRA registered labels for Exirel® and Verimark® contain the statement, “This product is highly toxic to bees exposed to direct treatment on blooming crops or weeds. Do not apply this product or allow to drift to blooming crops or weeds if bees are foraging in the treatment area.”
