伟大领袖毛主席指出:“病虫害是农业生产的最大障碍,彻底消灭其危害是保证农业增产的关键”。在林木生产中,防治害虫也是保证林木稳产高产的主要措施之一,近年来在大力发展药剂防治的同时,由于利用生物防治害虫具有不污染环境,不会使害虫产生抗药性和保护有益的天敌等特点,因而越来越被人们重视,我所几年来在生物防治方面,在参加全省生物防治会战后,继续开展榆紫金花虫的防治试验,利用茶色广喙蝽防治榆紫金花虫、黄刺蛾幼虫进一步观察效果。
Chairman Mao, the great leader, pointed out: “Pest and disease are the biggest obstacle to agricultural production and the complete elimination of their harm is the key to ensuring that agricultural production increases.” In tree production, pest control is also one of the main measures to ensure stable and high yield of trees. In recent years, while vigorously developing pesticide control, pest control has not been polluted by biological control and will not cause pest resistance and protection. Therefore, it has been paid more and more attention to by people. In the past few years, in biological prevention and control, I participated in the prevention and treatment of Ulmus violaceum after participating in the biological prevention and treatment of the province, Trichoplusia larvae to further observe the effect.
