Integrated fruit production under nets: low drift and low impact sprays used for thinning and other phytosanitary interventions in organic or pesticide-free orchards

Description

This project aims to validate the general hypothesis that the effectiveness of spraying through nets can be optimized by selecting appropriate spraying and exclusion parameters so as to achieve an adequate deposition rate of inputs, in terms of

• effectiveness against scab,
• effectiveness against aphids, and
• correction of fruit loads.

Objective(s)

Using a complete exclusion system for orchards as well as optimized air flow spray, measure:

• the deposition rate of the spray mixture applied according to various parameters (application volume, droplet size, tree girth, size of the net mesh), and
• the efficacy of the applied phytosanitary inputs as per the parameters offering the best deposition rate.
