水稻纵卷叶螟是水稻中后期的主要害虫。近年来,一直大发生,对水稻的增产增收构成极大威胁,常年都是选用高毒内吸性强的有机磷农药进行防治,但随着高毒农药的禁用和螟虫抗药性的产生,亟需开发筛选适用于无公害农产品生产的高效低毒、经济安全的替代药剂。毒丝本作为目前中等毒性新型农药,为取得毒丝本的应用效果,蕉岭县植保站于2006年5月在蕉城镇龙安村、叟乐村等进行了采用毒丝本防治水稻纵卷叶螟的试验,取得了较为理想的效果。
Rice leaf roller is the main pest in the late rice. In recent years, it has been a great threat to the increase of rice yield constitutes a tremendous threat to perennial selection of highly toxic organic phosphorus pesticide for prevention and control, but with the prohibition of highly toxic pesticides and stem borers resistance, the urgent need It is necessary to develop and screen suitable high-efficiency and low-toxicity, economical and safe substitute agents suitable for the production of pollution-free agricultural products. Toxic filaments present as a new type of moderate toxicity of pesticides, in order to obtain the application effect of Toxin, Plant Protection Station in Jiaoling County in May 2006 in Longan Village Jiaocheng, such as music village carried out the use of poisonous silk to prevent rice longitudinal leaf curling Borer test, and achieved a more satisfactory results.
