Verdepryn is a new insecticide registered for use in Wisconsin on several crops including pome fruit, grape, berries, and small fruit, including cranberry. It was registered in late 2019 and available for use starting this summer 2020. It is marketed by SummitAgroUSA™ under the formulation 100SL (100 grams of active ingredient per liter as a Soluble Liquid concentrate). Vedepryn, similar to Altacor and Exirel, is in the class of the anthranilic diamides (IRAC group 28), with a mode of action targeting the insect ryanodine receptors in the muscles, causing an uncontrolled release of calcium in the cells. Verdepryn contains the active ingredient cyclaniliprole. Verdepryn is an insecticide with foliar activity that is fast acting on contact or by ingestion of treated plant surfaces. Affected insects will rapidly stop feeding, become paralyzed, and eventually die. Verdepryn will kill both larvae and adults and has broad spectrum activity on many insect species. Verdepryn, Exirel and Altacor have the same mode of action and should NOT be used together in rotation to delay insecticide resistance, but rather insecticides from other IRAC groups (not IRAC group 28) should be used in rotation with these products.

In pome fruit, Verdepryn is registered for control of a variety of insects, including lepidopterans (codling moth, leafrollers, leafminers, etc), leafhoppers, plum curculio, and for suppression of thrips, apple maggot, and stink bugs. In grape, it controls grape berry moth, leafrollers, cutworms, Japanese beetle, spotted-wing drosophila, and can suppress populations of thrips and stink bugs. In berries and small fruits, it is registered to control leafrollers, cutworms, armyworms, Japanese beetle, and spotted-wing drosophila. More information on other insects and recommended use for certain species can be found on the label.

Verdepryn may be applied by ground equipment, chemigation, sprinkler irrigation and air. Spray volumes ranging from 20 to 100 gallons per acre for dilute sprays and 5 to 10 gallons for concentrate ground foliar applications are recommended. For more information on mixing and spraying, and all other considerations, please see the product label.

Verdepryn is highly toxic to bees exposed to direct treatment or residues on blooming plants. Do not apply Verdepryn when bees are foraging and until flowering is complete. Verdepryn is toxic to aquatic invertebrates and oysters and must not be applied directly to water.

As always, please make sure to read the label before using any pesticide. You can find the label of Verdepryn at the following link: http://www.cdms.net/ldat/ldEDF000.pdf
