雨季合理使用农药,应把握以下几点:选用速效性农药:如杀虫剂中的甲胺、久效磷,速灭杀丁等农药,具有很强的触杀作用,使用1~2小时后便可杀死害虫。可避免“慢性农药”因雨天药效流失的弊端。选用内吸性农药:如氧化乐果,呋喃丹、久效磷、杀虫双等杀虫剂及多菌灵、托布津、三环唑等杀菌剂。这些农药使用后4~6小时便有60%以上的有效成分被吸收到组织器官内部,6小时即使下大雨,仍可把害虫或病菌杀死。
Reasonable use of pesticides in the rainy season, should grasp the following: Quick-acting pesticides used: such as pesticides methylamine, monocrotophos, speed kill Ding and other pesticides, with a strong contact action, the use of 1 to 2 hours later Can kill pests. Can avoid “chronic pesticide ” due to the shortcomings of the loss of the efficacy of the rainy day. Adopt the absorption of pesticides: such as omethoate, carbofuran, monocrotophos, insecticide double pesticides and carbendazim, Topaz, tricyclazole and other fungicides. More than 60% of the active ingredients are absorbed into tissues and organs within 4 to 6 hours after use of these pesticides. Pests or germs can be killed even after heavy rain in 6 hours.
