几种除草剂药液表面张力、叶面接触角与药效的相关性研究

Study on Relationships between Surface Tension, Contact Angle and Efficacy on Weeds of Several Herbicide Solutions

摘要: 在除草剂氟磺胺草醚、灭草松和精喹禾灵药液中添加不同浓度的喷雾助剂ABS(十二烷基苯磺酸钠)和JFC ,以温室盆栽法测得各处理抑制杂草的效果,结果表明,在多数情况下添加喷雾助剂可使3种供试除草剂的药效显著提高。

Abstract: Fomesafen, bentazon and quizalofop-p-ethyl were applied respectively with or without spray adjuvant ABS(Sodium dodecyl benzene sulfonat) or JFC(Penetrating agent JFC) in greenhouse. The results showed that the efficacies of the tested herbicides were apparently enhanced after addition of spray adjuvants in most cases.
