| 摘 要： | 田间药效试验结果表明,剂量为80,100,120和150mL667m2的16%苏·三唑磷悬浮剂对水稻二化螟Chilosappressalis药后20d的防效分别为64.3,74.1,78.3和88.7%,对水稻的保苗效果为96.8%～99.1%。16%苏·三唑磷悬浮剂150mL667m2对二化螟的防效和保苗效果最佳,分别为88.7%和299.1%,与20%三唑磷乳油150mL667m2的防效88.8%和保苗效果99.1%差异不显著。

| Abstract: | The results of field trials showed the control efficacy of QianSui (16% Bacillus thuringiensis-triazophos SC) at dosages of 80, 100, 120 and 150?mL/667m~2 to Chilo suppressalis were 64.3, 74.1, 78.3 and 88.7% at 20 days after treatment respectively, and 96.8%～99.1% of the seedlings were protected. QianSui at dosage of 150?mL/667m~2 could control C. sappressalis effectively as 20% triazophos EC did. |
