生产优质无公害食品,是国内外农业发展的总趋势。今后植保工作的突出方向和特点如下。 1.防治虫害 不再使用老牌有机磷农药,如 1605、氧化乐果、3911、久效磷等。这类药剂均具有高毒、高残毒或致癌、致畸、致突变等特点,加之连续多年使用药效也大为减低,其中1605对蚜虫、红蜘蛛已基本无效,氧化乐果对蚜虫、红蜘蛛也达不到防治目的。象三氯杀螨醇、敌百虫、甲胺磷等已成为国家明令禁止使用的农药。为防果锈,在果树的幼果期,不但不能使用有机磷农药,连有机磷和菊酯类的复配药,如氯马乳油、速马乳油、菊马乳油、辛硫灭扫利、桃小灵等也尽量
Production of high-quality pollution-free food is the general trend of agricultural development both at home and abroad. The direction and characteristics of future plant protection work are as follows. 1. Pest control no longer use veteran organophosphorus pesticides, such as 1605, omethoate, 3911, monocrotophos. Such agents are highly toxic, highly toxic or carcinogenic, teratogenic, mutagenic and other characteristics, combined with the efficacy of continuous use for many years also greatly reduced, of which 1605 pairs of aphids, spider mites have been basically ineffective, omethoate on aphids, red Spiders also fail to control the purpose. Like dicofol, trichlorfon, methamidophos has become a national banned the use of pesticides. For the prevention of rust, not only can not use organophosphorus pesticides, even compound drugs of organophosphorus and pyrethroids, such as chlorpromazine, saimax, chrysanthemum EC, thiocarbanide, peach Healer also try as much as possible
