研究不同药剂水稻稻纵卷叶螟的防效,结果表明:25%·辛乳油在施用剂量为2250、2025g/hm2时,对水稻稻纵卷叶螟防效分别为84.46%、78.51%,有良好的防治效果。两者与对照药剂防效差异均达显著水平,而施用剂量为1800g/hm2时,较对照差异不显著。
The results showed that the control efficiency of rice leaf roller was 84.46% and 78.51% for the 25% Xinaxie oil at the dosage of 2250 and 2025g / hm2, respectively Good control effect. There was significant difference between the two and the control drug control effect, while the application dose of 1800g / hm2, compared with the control difference was not significant.
