螨类是农作物顽强的大敌,由於它的大量发生和迅速蔓延,常常造成农作物严重的减产,给国家带来很大的损失。所以无论果树、蔬菜和粮棉作物,螨类都是防治上重要的对象。石灰硫黄合剂及其他硫制剂、二硝基化合物等药剂早已被广泛的用作杀螨剂,并且有着攸久的使用历史。但是这些药剂的效果及其他各方面还远远不能令人满意。为了更好地防治螨类,各国科学家曾不断地在努力寻求新的杀螨剂。
Mites are tenacious enemies of crops and, as a result of their massive occurrence and rapid spread, often result in serious crop losses and great losses to the country. So regardless of fruit trees, vegetables and grain crops, mites are important targets for prevention and treatment. Lime sulfur compounds and other sulfur preparations, dinitro compounds and other agents have long been widely used as acaricides, and has a long history of use. However, the effectiveness and other aspects of these agents are far from satisfactory. In order to better control mites, scientists in various countries have been constantly trying to find new acaricides.
