Description

The principle behind thermal imaging is based on the fact that plants under water stress have a lower transpiration rate and a higher canopy temperature than plants well supplied with water. Canopy temperatures captured by drone can be used to quickly evaluate water stress in crops like lowbush blueberries and guide decisions as to whether irrigation is required.

  • Explore the potential of detecting water stress in lowbush blueberries using a thermal infrared imaging sensor installed on a drone

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.
