摘要
在室内采用水葫芦象甲与除草剂控制水葫芦的试验中发现象甲2头/株+200 mg·L^(-1)草甘膦对水葫芦的控制效果较显著,药后15 d死亡率达到100%;而象甲4头/株+46 mg·L^(-1)2,4-D二甲胺盐对水葫芦的防治效果显著,药后10 d死亡率达到90%以上,对照无死亡且有开花现象。
Two weevils per plant combined with 200 mg·L^-1 of glyphosate effectively controlled water hyacinth, and 15 days after the glyphosate was sprayed, the death rate was 100%. Four weevils per plant and 46 mg · L^-1 of butyl 2,4-dichlorophenoxy acetate also effectively controlled water hyacinth, and 10 days after spraying, the death rate was 90%.
