Description

The cranberry weevil (Anthonomus musculus) feeds on cranberry plants, and overwintering females lay their eggs on the flower buds, causing the flowers to abort. There are few or no pesticides registered for this pest. The aim of this two-year project was to determine the efficacy of various pesticides in the field.

Objective(s)

  • Field test six organic and conventional insecticides against the cranberry weevil on two cranberry farms compared to an untreated control:
    • BIOCERES® WP
    • GRANDEVO (MBI-203)
    • VENERATE (MBI-206)
    • CALYPSO® 480SC
    • CORAGEN®
    • ACTARA® 25WG

From 2015 to 2017
