Multifunctional nets: anti-hail, anti-cracking, anti-insect
The multifunctional net is a new model of rain and hail cover designed to protect the cherry tree against the D. Suzukii fruit fly.
Anti-insect nets
The practice consists of covering the fruit-farm with a mesh that is more tightly weaved than the classic hail-proof net in order to isolate it from external insect attacks (especially frugivores)
Anti-hail nets
Anti-hail nets are currently the only method of active protection effective against hail.
