柑桔红蜘蛛是柑桔上的一种重要螨类,为害严重时,可以造成叶落梢枯,严重的影响树势。随着我国工业化的迅速发展,杀虫、杀螨剂的新品种,均在日益增多,用来防治果树螨类害虫已日见广泛。为了探索新农药对柑桔红蜘蛛的杀虫、杀卵性能,为大面积提供防治措施,减少喷药次数,提高防治效果,特将1964—1973年在室内、外进行新农药防治柑桔红蜘蛛的试验结果,整理于下,以供参考。
Citrus red spider is an important citrus on the mites, serious damage, can cause leaves fall dry, a serious impact on the tree potential. With the rapid development of industrialization in our country, new varieties of insecticides and acaricides are increasing day by day. It has been widely used to control pests of fruit trees and mites. In order to explore the new pesticides on citrus red spider insecticidal and oviposition performance, to provide prevention and control measures for a large area, reduce the number of spraying and improve the control effect, especially 1964-1973 in the new pesticides indoors and outside prevention and treatment of citrus red Spider test results, sorted out for reference.
