复合型助剂对不同除草剂的增效作用

本文利用田间试验及仪器分析的方法系统研究了不同类型助剂对除草剂的增效作用.结果表明,供试的几种助剂对草甘膦都具有明显的增效作用,其增效顺序为:复合型助剂＞甲酯化植物油＞有机硅助剂＞非离子表面活性剂＞葡萄糖助剂＞氮盐类助剂.复合型助剂能够明显降低草甘膦药液的表面张力及干燥时间,降低幅度可达30％以上,并且明显增加药液的扩...

Synergistic effect of compound adjuvant on different herbicides

Synergistic effect of different types of adjuvants on herbicides was systematically investigated by field experiment and instrumental analysis. The results showed that different adjuvants had obvious synergistic effects on glyphosate, and the order of synergistic effect was: compound adjuvant>methylated vegetable oil>organosilicone adjuvant>nonionic surfactant>glucose adjuvant>nitrogen salts adjuvant. Compound adjuvant could significantly reduce the surface tension and drying time of glyphosate with the reduction rate of more than 30%, and significantly increase the spreading diameter, viscosity and maximum retention of the herbicide on the leaves with an increase rate of more than 40%. Therefore, the results showed that the compound adjuvant had a significant synergistic effect on glyphosate. In addition, the compound adjuvant had synergistic effect on clethodim EC and atrazine SC, and the plant control efficacy was increased by at least 9.34% and 10.41%, respectively.The higher the adjuvant amount, the more obvious the synergistic effect.
