Organic berry field farming is short on solutions that ensure good productivity and fruit quality. High tunnels are widely used around the world (over 1.6 million hectares) because extended growing seasons provide farmers with significant potential economic benefits. However, the main limiting factor is the effective control of insects such as thrips, mites, spotted wing drosophila, strawberry bud weevil, raspberry borer, tarnished plant bug, and tarsonemus. An improved design for high tunnels would lead to better control of climatic conditions and extended harvest periods. Lightweight structures that combine rain shelters and insect netting could provide a sustainable solution for small organic growers.

IRDA drew up a list of insects and mites in Québec known to be or likely to become resistant to pesticides.
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.
The hypothesis was that it should be possible to measure sap flow in apple trees and correlate it with soil water conditions and the weather.
