摘要
为探讨除草剂对浙西南柑橘园优势杂草的防除效果,选用10%双草醚悬浮剂、10%草甘膦水剂、10%草甘膦水剂+250g/L百草枯水剂的复配液处理浙西南柑橘园杂草。结果表明:相同条件下,以上3种除草剂或复配液对杂草铁苋菜和牛筋草的防效最低,但复配液对铁苋菜和牛筋草的防效高于单一除草剂,并呈显著性相关(P<0.05);铁苋菜和牛筋草在药后15d防效逐渐降低,而在其他优势杂草中没有出现此现象,说明该地区果园的铁苋菜和牛筋草对除草剂具有一定的抗药性。
The control effects of herbicides were explored on dominant weeds in citrus orcnaras in soumwest of Zhejiang province. The herbicides tested are bispyribac-sodium 10% SC, glyphosate 10% AS, and the composite liquid of glyphosate 10% AS and paraquat 250 g/L AS. The experiment discovers that the three kinds of herbicides cause the least control effect upon Eleusine indica and Herba acalyphae, but the control effect of the composite liquid is significantly better than bispyribac-sodium and glyphosate aqueous solution （P〈0.05）. Eleusine indica and Herba acalyphae are herbicide resistant to some extent because the control effect of the herbicides on the two kinds of weeds decreases gradually 15 days after the herbicides are used, whereas the effect keeps strong on other dominant weeds.
