5种杀虫剂防治甘蔗绵蚜田间药效试验

The Effect Test of 5 Insecticides to Control Ceralovauna lanigera Zehnther

本文报道了５种农药、１１个处理防治甘蔗绵蚜的田间药效试验结果。丁硫克百威、甲基硫环磷２０００、３０００、５０００倍的田间防效３～１４天均在９９％以上，可做为甘蔗绵蚜防治中的轮换用药。

The tests of control Ceralovauna lanigera Zehnther with 5 insecticides were performed in 1995.The results showed that the control effect of each of tests was over 99% after 3～14 days by using 2000,3000 and 5000 times diluent of 35% cyolane-methyl EC and 20% carbosulfan EC.These effects were similar to 2000 times diluent of 40% omethoate EC and 3000 times diluent of 50% pirimicarb DG.Therefore,35% cyolane-methyl EC and 20% carbosulfan EC are effective pesticide to control Ceralovauna lanigera Zehnther.It is suitable to use 3000～5000 times diluent in the field.
