Abstract

The control of insect pests on Japanese radish, cauliflower, Chinese cabbage and Iceberg lettuce using polyethylene netting (with mesh sizes of 0.6, 0.8 and 1.35 mm) was investigated in field trials in The Netherlands in 1988-1991. Insect nets (1.35 mm) protected cauliflower, against damage from Delia radicun, Brevicoryne brassicae and Lepidoptera spp., and Japanese radish against D.radicum. Similar results were obtained with nets against D.radicum, Liriomyza huidobrensis and Contarinia nasturtii on Chinese cabbage. Lettuce was fully protected against L.huidobrensis and aphids with a mesh size of 0.6 and 0.8mm, however summer covering adversely affected yield and quality. Evaluation of spraying techniques, for application of pesticides through the net, was carried out in 1992-1993. With air assistance and/or coarse droplet size, in excess of 80% of the spray volume penetrated the net.
