摘要
试验结果表明,根施30%度锐SC、70%锐胜WG和40%福戈WG三种杀虫剂防治甘蔗螟虫、蓟马、绵蚜虫都有良好防治效果。施药后60d,螟害枯心防效达70%以上;10株蓟马虫量防治效果在65%以上,有虫株防效下降,但明显优于对照;除40%福戈WG 450g/hm2有绵蚜虫危害外,其它各药剂处理防治效果均达100%,明显优于对照。生产上应用以30%度锐SC 600mL/hm2、70%锐胜WG 225g/hm2、40%福戈WG 600g/hm2为宜,结合甘蔗下种和施肥培土,与化肥混合均匀,施用后及时覆土。
The test results show that there were control effects of root applied Chlorantraniliprole 30% thiamethoxam SC, 70% thiamethoxam WG and 40% Virtako WG three pesticides on sugarcane borer, thrips and mealy bug. After applying pesticide 60 days, control effect of borer dead heart was more than 70%; control effect for thrip numbers of 10 plants was more than 65%, control effect of pests on plants decreased, but obviously was superior to that of the control; there was mealy bug harm on 40% Virtako WG 450 g/ha, but the control effects of the other agents were 100% superior to that of the control. Application dosage was suggested to 30% thiamethoxam Chlorantraniliprole SC 600 mL/ha, 70% thiamethoxam WG 225 g/ha and 40% Virtako WG 600 g/ha used combing with sugarcane seeding, fertilization and ridging.
