The Pest Management Regulatory Agency (PMRA) recently announced the approval of a minor use label expansion registration for Delegate Insecticide (spinetoram) for suppression of chestnut weevils and hazelnut weevils on tree nuts, crop group 14-11 in Canada. Delegate Insecticide was already labeled for use on tree nuts for certain other pests, however prior to this label expansion there were no registered products available to control hazelnut and chestnut weevils in Canada.

These minor use projects were submitted by Ontario as a result of minor use priorities established by growers and extension personnel.

The following is provided as an abbreviated, general outline only. Users should be making pest management decisions within a robust integrated pest management program and should consult the complete label before using Delegate Insecticide.

For suppression of hazelnut weevil, large chestnut weevil and small chestnut weevil on tree nuts, Crop Group 14-11 (almond, beech nut, butternut, chestnut, chinquapin, hazelnut, hickory nut, pecan and walnut), apply 420 g Delegate/ha. Monitor trees and apply at the first sign of adult feeding damage. Repeat in 14 days if populations warrant. Apply a maximum of 3 applications per year, and do not apply within 14 days of harvest.

Delegate Insecticide is toxic to bees exposed to direct treatment, drift or residues on blooming plants. Do not apply this product or allow it to drift to blooming plants if bees are visiting the treatment area. Delegate Insecticide is also toxic to small wild mammals
and certain beneficial insects. Do not apply this product or allow drift to other crops or non-target areas. Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers. Follow all other precautions, restrictions and directions for use on the Delegate Insecticide label carefully.
