除草剂谷友对谷田杂草的除草效果及对谷子安全性的影响

Effects of Monosulfuron Plus Propazine on Weed Control in Millet Field and Its Security

以冀谷19为试材,研究了44%谷友(单嘧.扑灭)WP对谷田杂草的田间防效及对谷子安全性的影响。结果表明:44%谷友最佳使用剂量为1 800 g/hm2。在该剂量下,除草效果较好,且对谷子生产安全,谷子产量与人工锄草基本相同,但较50%扑灭津WP(药剂对照)增产显著。

Using Jigu 19 as the material,the effects of 44% monosulfuron plus propazine WP on the weed control in millet field and its security were studied.The results showed that the optimum quantity was 1 800 g/hm2,which was safe to millet.With the quantity,the yield was basically same to that of artificial weeding,which increased significantly than that of 50%propazine WP.
