毒力测定结果表明 :40 %杀·井WP(两单剂的混配 )既无增效亦无拮抗作用。田间试验结果表明 :该混配药剂对水稻螟虫、纹枯病具有较好的防治效果 ,在江苏用量 15 0 0~ 180 0g/hm2 对水稻螟虫的防效为 86 .2 6 %~ 90 .88% (保苗 )、89.6 3 %~93 .90 % (杀虫 ) ,对水稻纹枯病的防效为 85 .6 0 %~ 84.93% ;在江西同等剂量用药对螟虫防效为 89.11%~ 94.49% ,对纹枯病药后 7d防效为 42 .6 2 %~ 42 .93 %、药后 14d的防效为 44.2 5 %~ 5 5 .18% ,均与对照药剂效果相近。
Toxicity test results show that: 40% kill well WP (two single-dose mix) neither synergistic nor antagonistic effect. The results of the field experiment showed that the compounding agent had good control effects on rice stem borer and sheath blight, and the control effect on rice stem borer at the rate of 1500 ~ 180 g / hm2 in Jiangsu Province was 86.26% -90.88 % (Seedlings) 89.6 3% ~ 93 .90% (insecticide), the control effect on rice sheath blight was 85.60% ~ 84.93%; the same dose of Jiangxi province for the control of stem borers 89.11% ~ 94.49 %, The control effect of sheath blight on the 7th day was 42.62% -42.93%, and the control effect on the 14th day after treatment was 44.2% -5.518%, all of which were similar to the control.
