摘要
用灭扫利与马拉硫磷 2种农药以 1∶1 ,1∶1 5,1∶2和 1∶3等 4种混配比例以及 2种农药单剂对马尾松毛虫进行室内毒力测定。结果表明 :灭扫利与马拉硫磷以 1∶1混配的共毒系数最高 ,增效作用明显 ,其次是 1∶3,1∶2 ,而以 1∶1 5最差。图 1表 1参
Toxicity test was conducted with four mixtures of fenpropthrin and malathion in proportion as 1∶1,1∶1 5,1∶2,1∶3 and two pesticide units to Dendrolimus punctatus (Walker) indoors.Tests result shows the blend formula in proportion as 1∶1 have the best toxicity affect and obvious reinforcement affect as well.It provides scientific basis for control harm of Dendrolimus punctatus(Walker).Next are 1∶3,1∶2,and the worst is 1∶1 5.
