地蚜灵简化高效防治技术试验研究

Study on Efficient Control Technology of Diyaling

为探索油菜蚜虫高效防治技术,在油菜播种时,采用环保型地蚜灵药剂进行不同施药方式和不同施药量的试验。2年试验结果表明,地蚜灵防治效果突出,平均防效达75.73%~91.04%,其中,施药600~1 200g/hm^2,施药后覆土防效显著。

To explore the effective control techniques of aphids in rape,we applied different dosage of environment-friendly Diyaling with different methods. From two years experiments,we found out that Diyaling is high efficient.The average prevention effect can reach 75.73%～91.04%. Especially when we applied 600～1 200g/hm2 and coveredseeds with soil, the effect was the highest.
