Description

In highbush blueberry fields where stunt disease has been detected, plants that have never received nitrogen fertilizer are more vigorous and homogeneous than plants that have received nitrogen fertilizer. The purpose of the exercise was to learn more about the productivity (fruit yield) of these plants, which do not appear to be affected by this pathogen.

Objective(s)

  • Improve knowledge about the role of nitrogen fertilizer in the expression of stunt disease symptoms and the productivity of blueberry fields
  • Improve knowledge on the impacts of blueberry stunt disease on fruit yield and eating quality
  • Educate industry stakeholders about this pathogen and its impacts on blueberry fields

From 2015 to 2016

Using multitask nets and mechanization to eliminate pesticide use in apple orchards

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.
