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.

IRDA is able to assess the effectiveness of a variety of biopesticides for many types of crops.

Exclusion nets have proven to be effective against nearly all of these insect pests, which means that it’s possible to develop apple growing practices in Québec that are not only neonicotinoid free, but also devoid of all pesticides (including acaricides, given that mite problems are a consequence of broad-spectrum insecticide use). Although the net exclusion microsystem studied in Québec since 2012 has demonstrated its effectiveness in controlling insect pests, some issues remain to be studied before it can be unreservedly recommended. Among these are the handling times for the nets, i.e., installation/removal and opening/closing, and the system’s profitability and durability over the long haul for various cultivars.

This project looks to incorporate the data for the recommended IFP berry products into the SAgE Pesticides database. The goal is to encourage farmers to adopt IFP and make it easier for them to access IFP data.

This project seeks to reduce the use of chemical insecticides in orchards by controlling apple maggot populations using mass trapping.
