一、呋喃丹农药
carbofuran

氨基甲酸酯类杀虫剂和杀线虫剂。1963年由美国创制，1967年推广。纯品为白色结晶，25℃时水中溶解度为700ppm，在中性和酸性条件下较稳定，在碱性介质中不稳定，水解速度随pH值和温度的升高而加快，在水田中半衰期为1～2天，土壤中为30～60天。是内吸剂，兼有触杀作用，能被植物根、茎、叶吸收，并在体内传导。杀虫谱广，对稻、棉、甜菜、烟草、大豆等多种作物及林木、花卉上的多种害虫和线虫有效。持效期长，一般可达30～40天。剂型主要是颗粒剂。防治地上害虫亩用有效成分35～60克，防治地下害虫和线虫用200～250克。防治稻虫采用土壤或水面施药法，防治旱田作物害虫和地下害虫、线虫时随种子播入土中，作物生长期可将药条施或沟施入土中，不能将颗粒剂浸水后喷雾。
