To maintain and enhance environmental and health gains, this project will develop a strategy for biological control of the obliquebanded leafroller in orchards where mating disruption is being used against the codling moth.
The initial phase of the project will involve fine-tuning applications of the parasitoid Trichogramma minutum so that releases to control OBLR are uniform and cost effective.
In the second phase we will assess the obliquebanded leafroller populations in a number of Québec orchards.
In the third phase we will compare three strategies for controlling the obliquebanded leafroller that combine crop practices, a Bacillus thuringiensis var. kustaki (Bt) insecticide, and the inundative release of Trichogramma minutum into commercial orchards already using mating disruption against the codling moth.

Compared with insecticide applications, this method reduces the risks to human health and the environment.

This project aims to promote a biocontrol solution by testing a complex of natural enemies that attack the spotted wing drosophilia at different development stages.

The aim of this project was to field-test sound irrigation practices and band application of various types of fertilizers at ridging time to eliminate fertigation and increase the efficiency of fertilizer and water use under plastic mulch.
