Apples
2019-2020 • Fruit production

Using carbohydrate-balance bioclimatic modelling to develop carbaryl-free apple fruit thinning strategies

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.

2019-2022 • Market gardening

Developing mass trapping strategies to control the striped cucumber beetle in organic cucurbit farming

This project aims to develop mass trapping strategies to keep damage caused by the striped cucumber beetle populations below the economic threshold, while minimizing the capture of pollinators and natural enemies.

Apples
2019-2020 • Fruit production

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.
