本研究旨在明确农药增效剂(主要成分为复合型改性植物油,复合型糖醇类,非离子表面活性剂等)对精异丙甲草胺、异丙甲草胺、乙草胺、氟磺胺草醚、灭草松、异噁草松、精喹禾灵、莠去津、硝磺草酮、环磺酮、苯唑草酮和敌草快12种除草剂物理性质的作用效果,本研究测定了农药增效剂对12种除草剂一系列物理指标的影响.结果表明,在12种除草剂中分别添加助剂农药增效剂后,其物理性质均有不同程度的改善.混用农药增效剂后,11种除草剂的接触角显著性降低,9种除草剂的扩展直径显著性增加,3种除草剂的表面张力显著性降低,7种除草剂在阔叶类杂草(葎草)上的最大持留量显著性增加,9种除草剂的渗透时间显著降低.由此可见,农药增效剂对12种除草剂的物理性质作用效果明显具有增强药效的基本条件,对其除草效果的增效作用需进行进一步的生物测定来验证.
Effects of Pesticide Synergists on Physical Properties of 12 Herbicides
This study aims to clarify the effect of pesticide synergists(mainly composed of compound modified vegetable oil,complex sugar alcohols,and non-ionic surfactant)on the physical properties of s-metolachlor,metolachlor,acetochlor,fomesafen,bentazone,clomazone,quizalofop-p-ethyl,atrazine,mesotrione,tembotrione,topramezone and diquat.The effects of pesticide synergists on a series of physical indexes of 12 herbicides were measured.The results showed that the physical properties of 12 herbicides were improved by different pesticide synergists.After each herbicide is mixed with pesticide synergist,11 herbicides had a significant decrease in contact angle,9 herbicides had a significant increase in expansion diameter,3 herbicides had a significant decrease in surface tension,7 herbicides had a significant increase in maximum retention on broadleaf weeds[Humulus scandens(Lour.)Merr.],and 9 herbicides had a significant decrease in penetration time.The results show that pesticide synergists have a basic condition for enhancing the physical properties of the 12 herbicides,and the synergistic effect of their weeding effect needs to be further verified through bioassay.
