【摘要】 采用茎叶定量喷雾法测定了18种除草剂对温室盆栽木薯的安全性。结果表明,5%精喹禾灵EC900~1800 ml/hm~2、6.9%精噁唑禾草灵EC 750~1500 ml/hm~2、24%烯草酮EC 225~450 ml/hm~2和10.8%和高效氟吡甲禾灵EC 450~900 ml/hm~2对木薯无药害症状,对木薯安全;48%灭草松AS 2250~4500ml/hm~2、25%氟磺胺草醚AS 1200~2400 ml/hm~2、10%硝磺草酮SC 1500 ml/hm~2、10%乙羧氟草醚EC 750 ml/hm~2和21.4%三氟羧草醚EC 900 ml/hm~2会造成轻微药害症状,但木薯恢复快,药后30天对木薯的株高抑制作用不明显;20%氯氟吡氧乙酸EC 750~1500 ml/hm~2、24%甲咪唑烟酸AS 300600ml/hm~2、5%咪唑乙烟酸AS 1,500~3000 ml/hm~2、15%乙氧嘧磺隆WP 75~150 g/hm~2、95%2.4-D钠盐TF 750~1,500g/hm~2和10%双草醚SC 225~450ml/hm~2对木薯安全性差,不能施用。更多还原

【Abstract】 Safety research of eighteen herbicides to Cassava(Manihot esculenta Crantz) was tested in greenhouse by using spray method.Results showed that quizalofop-p-ethyl 5%EC at 900~1800 ml/hm~2,fenoxaprop-P-ethyl 6.9%EC at 750~1500 ml/hm~2,clethodim 24%EC at 225~450 ml/hm~2 and haloxyfop-Rmethyl 10.8%EC at 450~900 ml/hm~2 were safe to cassava at 8 to 10 leaf stages.Bentazone 48%AS at 2250~4500 ml/hm~2,fomesafen 25%AS at 1200~2400 ml/hm~2,mesotrione 10%SC at 1500 ml/hm~2,fluoroglycofen10%EC at 750 ml/hm~2 and acifluorfen sodium 21.4%EC at 900 ml/hm~2 could cause light injury to cassava,but the injury can recover in short time and cassava had insignificant inhibitory on plant height 30 days after treatment.Fluroxypyr 20%EC at 750~1500 ml/hm~2,imazameth 24%AS at 300~600 ml/hm~2,imazet 5%AS at1500~3000ml/hm~2,ethoxysulfuron 15%WP at 75~150g/hm~2,2,4-D-sodium 95%TF at 750~1500g/hm~2 and bispyribac-sodium 10%SC at 225~450 ml/hm~2 were not safe to cassava in this study.更多还原
