Description

Improving the RIMpro software to better predict the risk of infection during rainfall.

Objective(s)

  • Determine how infection speed varies with temperature and to better understand the impact of drying periods on spore survival.
  • Update RIMpro, a free software application already used by producers, based on the results of the project.
  • Improve treatment decisions, with no additional complications or increases in risk, by better defining the period during which germination (stop) treatments are recommended.

From 2015 to 2018

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.
