摘要
助剂对除草剂有增效作用,但不同类型助剂对除草剂增效作用差别很大。温室试验可知:无机盐助剂单独使用时增效效果不明显,剂量与药效之间没有明显关系;但与植物油混用时可以在降低除草剂剂量和植物油剂量的同时,达到较好除草效果,从而降低成本。
Adjuvants increase postemergence herbicide efficacy, but adjuvant type greatly affects herbicide efficacy enhancement by the adjuvant. In greenhouse experiments, inorganic salts used alone did not significantly enhance nicosulfuron efficacy, and no nicosulfuron rate response was evident. However, when applied with a methylated vegetable oil adjuvant plus ammonium sulfate, nicosulfuron provided relatively good control of green foxtail and large crabgrass, even with low rates of both herbicide and methylated oil adjuvant, thereby resulting in reduced treatment costs.
