摘要
[目的]筛选出对入侵性杂草假臭草高效的除草剂品种。[方法]采用茎叶喷雾法,连续2年用4种除草剂,1种复配制剂防除柑橘园中假臭草。[结果]41%草甘膦异丙胺盐水剂1 950 g a.i./hm2,200 g/L百草枯水剂750、900 g a.i./hm2、18%草铵膦水剂900、1350、1800 g a.i./hm2和41%草甘膦异丙胺盐+13%2甲4氯钠水剂复配液(1050+450)、(1500+450)、(1950+450)g a.i./hm2防除假臭草药后15、30 d的防效均在70%以上。[结论]18%草铵膦和41%草甘膦异丙胺盐+13%2甲4氯钠复配剂对假臭草最敏感,在农业生产中建议除草剂组合或交替使用,防治果园中入侵性杂草蔓延。
[Aims] In order to screen out herbicides with highly control effect to control invasive weeds Eupatorium catarium Veldkamp. [Methods] Four herbicides and one combined preparation were evaluated by foliar spraying in citrus field for 2 years. [Results] On 15th day and 30th day after treatment, the control effect of glyphosateisopropylammonium 41% AS 1 950 g a.i./ha, paraquat 200 g/L AS 750, 900 g a.i./ha, glufosinate-ammonium 18% AS 900, 1 350, 1 800 g a.i./ha, 41% glyphosate-isopropylammonium conbined 13% MCPA-Na (1 050+450), (1 500+450), (1 950+450) g a.i./ha were all above 70%. [Conclusions] E. catarium were the most sensitive to glufosinate-ammonium 18% and glyphosate-isopropylammonium 41% conbined MCPA-Na 13%, herbicide should be combined or alternately used to control resistance weeds spread in agricultural production.
