【摘要】 选用78%溴腈.莠灭净WP,95%草甘膦原药+草甘膦伴侣WP,20%噻吩磺隆WP,95%草甘膦铵盐SG,20%氯氟吡氧乙酸EC,20%百草枯AS,25%百草枯AS共7种除草剂,于2010年在柳州市柳南区太阳村镇董家屯的农民鱼塘进行防除凤眼莲[Eichhornia crassipes(Mart.)Soims]的小区药效试验。试验结果表明,78%溴腈.莠灭净WP,20%百草枯AS和25%百草枯AS的防效均为100%;95%草甘膦原药+草甘膦伴侣WP的防效为93.2%~93.6%;95%草甘膦铵盐SG的防效为90.8%~91.4%。在900~4500g(ml)/hm2剂量范围内7种除草剂对水生生物安全,对周边环境无不良影响和危害。更多还原

【Abstract】 The effects of 7 herbicides on controlling Eichhornia crassipes were observed in fish ponds.The results showed that the control effect of 78% Bromo nitrile·Ametryn WP and 20%Paraquat AS was 100%;the control effect of 95% mixture WP by the Glyphosate and the Glyphosate companion was 93.2% to 93.6%;the control effect of 95% Glyphosate ammonium SG was 90.8% to 91.4%.All 7 herbicides were safe to the aquatic in the fish ponds and the environment when they were in the dose range from 900ml to 4500ml per hm2.更多还原
