Effect of Sulfentrazone 75% WG on Control of Bindweed(Convolvulus arvensis L.) in Soybean Field
【摘要】 为验证75%氟磺唑草胺WG对多年生杂草田旋花的防除效果和持效期,采用大豆播种后苗前土壤喷雾,定期调查的方法进行田间药效试验。结果表明,75%氟磺唑草胺320~440 g a.i./hm2,兑水750 L/hm2喷雾,药后40 d对田旋花的株防效为68.4%~98.3%,第二年对田旋花株防效依然能达到45.3%~90.1%。
【Abstract】 In order to test the control efficiency and effective period of sulfentrazone 75%WG on the perennial weed bindweed(Convolvulus arvensis L.),field trial was conducted by soil spraying with the herbicide after soybean seeds sowing but before seedling emergence,and by regular investigation.The results showed that when sulfentrazone 75%WG was applied at the dose of 320~440 g a.i/hm2,adding 750 L/hm2 of water to spray,the individual plant control efficiency of bindweed was 68.4%~98.3% after spray herbicide for 40 days,and was still reach to 45.3%~90.1% in the second year.
