| 杀螨剂 acaricide 防治植食性螨类的农药。一般只能杀螨不能杀灭昆虫。理想的杀螨剂应对防治多种有害螨类的成螨、幼螨和卵均有效，且有速效性和持效性，理化性质稳定，能与多种农药混用。同时对天敌表现较小或无害的选择毒性，对作物无药害，对人畜毒性低，不易使叶螨产生抗药性等，但完全符合上述要求的杀螨剂尚少。杀螨剂按化学结构可分为17类：硫黄类、二硝基酚类、二苯基醇类、二苯氧基甲烷类、二苯基砜类、二苯基磺酸酯类、亚磺酸脂类、二苯基醚类、二苯基硫醚类、喹噁啉类、磺酰胺类、苯羟肟酸酯类、脒类、苯并咪唑类、苯腙类、有机锡类和抗生素类等。将二三种杀螨剂制成混合制剂可以延缓叶螨出现抗药性的期限，也可转换用药或一年内某种杀螨剂只用一次或采用综合防治等方法防止螨类产生抗药性。 |
