摘要
棉花播后苗前喷施30%乙草胺.扑草净悬浮剂,研究其除草效果及对棉花的安全性。结果表明:该药剂对棉田禾本科杂草及大部分阔叶杂草防除效果理想,药后遇雨(土壤湿度太大)对棉花幼苗有一定药害,但长出真叶后逐渐恢复正常生长,对子棉产量基本无影响。
30% Acetochlor · prometryne SC was sprayed on soil with pre-emerge cotton to study its control effect on weed and safety to cotton. The results showed that excellent weed control effect was obtained. Injuries of cotton seedling were observed in the condition of higher soil humidity. After the true leaf appeared, cotton plant could recover regular growth from damage caused by the herbicide. The seed cotton yield wasn＇t significantly influenced by the herbicide.
