4种除草剂土壤封闭处理对稻茬紫云英的安全性及对阔叶杂草的防除效果
Study on the Safety of Soil Closure Treatment with Four Herbicides on Astragalus sinicus after Rice and Its Control Effect on Broad-leaved Weeds
摘要
Abstract
In order to screen the herbicides used in soil treatment to control broad-leaved weeds in the breeding field of Astragalus sinicus after rice,4 herbicides including 80％flumetsulam water dispersion granules,960 g/L S-metolachlor emulsifiable concentrate,33％S-metolachlor·flumioxazin microcapsule suspension and 330 g/L pendimethalin emulsifiable concentrate were selected and soil spray treatments were applied before seedling emergence of Astragalus sinicus,and their safety and control effect on broad-leaved weeds were evaluated.Results showed that soil spray on the second day after sowing Astragalus sinicus,80％flumetsulam water dispersing granules and 330 g/L pendimethalin emulsifiable concentrate were safe for Astragalus sinicus and had the best control effect on broad-leaved weeds in the field,plant control efficiency were 75.26％,82.74％,respectively,whereas fresh weight control efficiency were 46.09％,61.09％,respectively.关键词
