采用0.3%印楝素乳油以90 mL/667m2对水45 kg喷雾,对高粱条螟和水稻二化螟进行田间防治的药效试验。结果表明:施药后3 d对高粱条螟和水稻二化螟的防治效果分别达83.3%和80.95%;施药后7 d对高粱条螟和水稻二化螟的防治效果达92.69%和95.65%,均达到化学农药的防治效果,且不残留、不污染环境、不产生药害。
The 90 mL/667m^2 of 0.3% azadirachtin EC with 45 kg water was sprayed in the sorghum field to investigate the control effect on Proceras venosatus walker and Chilo suppressalis Walker. The results showed that the effects of controlling Proceras venosatus walker and Chilo suppressalis Walker after 3d were 83.3% and 80. 95%, and the effects of controlling Proceras venosatus walker and Chilo suppressalis Walker after 7 d were 92. 69% and 95. 65% respectively.
