摘要: 为明确新型土壤封闭除草剂砜吡草唑对花生和向日葵田主要杂草的防除效果及对2种作物的安全性,设置该药剂4个用量及对照药剂、人工除草、空白对照处理,采用随机区组的试验方法进行田间药效试验。结果表明,砜吡草唑有效成分在120~180 g/hm2时对花生和向日葵田1年生杂草具有良好的防除效果,在花生和向日葵播后苗前进行土壤均匀喷雾,药后45 d总草株防效和总草鲜质量防效均能达到90%以上,能够有效控制杂草的危害,并且对2种作物较为安全,相比空白对照增产效果明显,可以作为花生和向日葵田的备选除草剂。

Abstract: To clarify the control effect of new soil blocking herbicide pyroxasulfone on main weeds in peanut and sunflower fields,and the safety to the two crops,four dosage treatments of pyroxasulfone,contrast herbicide,manual weeding and blank control treatments were set,and field efficacy test was carried out by randomized block. The results showed that pyroxasulfone had a good control effect on annual weeds in peanut and sunflower fields in the dosage range of 120—180 g/ha.When soil spray was applied evenly to peanut and sunflower after sowing and before seedling emergence,the total plant control efficiency and total fresh weight control efficiency could reach more than 90% at 45 days after treatment.It could effectively control the damage of weeds,and was safer to two kinds of crops,so the effect of increasing production was obvious compared with blank control.It could be used as a candidate herbicide
for peanut and sunflower fields.
