Description

The goal of the project is to select a strain of the mullein bug to control two spotted and red spider mites from July to August (period when populations tend to explode).

Objective(s)

  • Select a voracious strain of spider mite predator through isogroup selection
  • Field test minimum mullein bug introduction rates required to keep spider mite populations below the economic threshold
  • Determine how long the predators stay on apple trees and how effective they are
  • Improve mass rearing techniques by testing two food sources and two host plants

From 2016 to 2019

Exclusion nets for organic apple production in Eastern Canada

The aim of this project was to test the general hypothesis that exclusion nets, when properly used, can prevent attacks by most apple pests and reduce disease incidence with no major adverse effects on fruit quality.
