摘要
[目的]测定无机盐助剂、油类助剂和有机硅助剂分别与480 g/L灭草松水剂混用对防除野慈姑的增效作用。[方法]通过室内生物活性测定,将3种喷雾助剂按不同剂量和配比与480 g/L灭草松水剂混用,测定对野慈姑的毒力。[结果]1.5 L/hm^2油类助剂英伏腾分别与30、80、160 mmol/L硫酸铵混用时,对野慈姑的鲜重防效分别为74.9%、75.8%和76.8%,增效幅度均达到43.0%以上。[结论]初步确定480 g/L灭草松水剂与硫酸铵和英伏腾混用对野慈姑有明显的增效作用。
[Aims] This paper aims to determine the control effects of bentazonemixed with inorganic, oil and surfactant respectively agaisnt S. trifolia. [Methods] Three kinds of spray adjuvants at different doses were respectively mixed with bentazone to determine the toxicity to S. trifolia in the greenhouse. [Results] The mixture ofbentazone with infil tractor(1.5 L/ha), ammonium sulphate(30, 80 and 160 retool/L, respectively)showed good control effects on S. trifolia, the fresh weigh control effect reached 74.9, 75.8 and 76.8%, respectively. The synergism increased by more than 43.0%. [Conclusions] Preliminary determination indicated that bentazone mixed with infil tractor and ammonium sulphate has obvious synergistic effect.
