The model’s predictions will be used to calibrate the dose of a thinning agent (ANA) to be applied in two plots, one treated with carbaryl and the other without, over a two-year period. The agent will be tested under Québec’s climatic conditions to ensure that the technology can be transferred to growers.

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.
