保护地蔬菜害虫种类多,常年发生的主要有粉虱、害螨、蚜虫、蓟马等4类害虫,一般造成损失30%以上,严重时甚至绝产。由于保护地特殊的栽培环境,化学农药降解难度大、污染严重。生物防治技术是农业生产中替代化学农药使用、提升农产品质量安全的有效途径。为做好防控工作,特制定本方案。一、防控目标保护地蔬菜重要害虫防治处置率90%以上,害虫总体防治效果80%以上,危害损失率控制在15%以下,
Protected vegetable pests and more perennial occurred mainly whitefly, pest mites, aphids, thrips and other 4 kinds of pests, generally cause more than 30% loss, even when absolutely absent. Due to the special cultivation environment of the protected area, the chemical pesticides are difficult to degrade and have serious pollution. Biological control technology is an effective way to replace the use of chemical pesticides in agricultural production and improve the quality and safety of agricultural products. In order to do a good job in prevention and control work, we formulated this plan. First, the prevention and control targets Protected vegetable pests control and disposal rate of 90% or more, the overall pest control effect of more than 80%, the hazard loss rate controlled at 15% or less,
