摘要
用 8种农药设 8个处理对防治梨木虱若虫和卵进行田间药效试验 ,试验结果表明 :药后 3d ,虱螨净 2 0 0 0×、特杀 15 0 0×、蚍虫啉 15 0 0× +氧化乐果 80 0× ,莫比朗 15 0 0×以及巨力杀 10 0 0×对若虫的防效均达 10 0 %。其中以虱螨净 2 0 0 0×和特杀 15 0 0×的残效最佳 ,用药后 14d对若虫的防效仍达 10 0 %。除果蔬利 35 0 0×外其它参试药物的各个处理 ,对梨木虱的卵防效均好 ,药后 14d防效达 90
The efficacies of 8 pesticides against nymph and egg of pear psylla (Psylla chinensis) were tested in the field experiment in which 8 treatments were included. The result indicates that efficacies against nymph with buprofezin 2000×, Tesha 1500×, 10% imidacloprid wp 1500×+omephoate 800×, Mospilan Ec 1500× and julisha 1000× are all 100% 3days after spraying. The residual effects of buprofezin 2000× and Tesha 1500× Were still as high as 100% 14 days after spraying. Excepting Guoshuli, all other treatments of the tested pesticides to control egg possessed excellent efficiencies which are over 90% 14days after spraying.
