摘要: 为筛选防治刺萼龙葵的安全、高效的土壤处理除草剂,采用温室盆栽法对5种土壤处理除草剂进行了室内生物测定。结果表明,乙草胺对刺萼龙葵活性最高,ED90为41.43 g a.i./hm2;二甲戊灵最低,ED90为748.56 g a.i./hm2。5种除草剂ED90由高到低的顺序为乙草胺>;异噁草松>;甲草胺>;精异丙甲草胺>;二甲戊灵。综合考虑药剂活性及其推荐剂量,乙草胺、异噁草松、甲草胺、精异丙甲草胺和二甲戊灵均可在低于推荐剂量下用于防除刺萼龙葵。

Abstract: To screen for safe and effective soil-applied herbicides to prevent and control of buffalobur, pot experiments were conducted to evaluate the control effect of 5 preemergent herbicides against buffalobur, and greenhouse bioassay were further conducted for the herbicides with better control effects. The results showed that the toxicity of acetochlor was the highest, while that of pendimethalin was the lowest, the ED90 were 41 . 43 and 748. 56g a. i. /hm2, respectively. The order of toxicity was acetochlor > clomazone > alachlor > s-metolachlor > pendimethalin. Based on consideration of herbicidal activity and recommended rate, the 5 herbicides could be used to controlbuffalobur at lower dose than recommended.
