Poster presentation at the “Güttingertagung” about exclusive netting in apple growing.
To investigate the influence of exclusive netting on pest insects and the microclimate, Agroscope started in 2012 a long-term research project with the varieties Opal and Milwa-Diwa. Out of 16, eight tree rows are only covered with a hail net, whereas the other half is additionally enclosed with a fine-meshed side net from full bloom until harvest. Since 2016, the effects of the side net on pest and beneficial insects, fruit growth, the photosynthetic activity, the amount of fruits harvested, the fruit quality and the microclimate are measured.
First results indicate that side nets successfully protect apple orchards from pest insects without influencing temperature or fruit quality at harvest.
