助剂对啶虫脒静电喷雾液剂的物理性能及沉积量的影响

Effect of Adjuvants on Physical Properties and Target Deposition of Acetamiprid 10ED

摘要: 研究了1%啶虫脒静电喷雾液剂配方中助溶剂N-甲基吡咯烷酮和导电剂农乳500#含量的变化对该制剂电导率、粘度、挥发率的影响，同时利用农药残留检测方法测定静电喷雾的沉积量，研究了该制剂中助溶剂和导电剂含量的变化对1%啶虫脒静电喷雾液剂静电喷雾时在玉米叶片正面和反面上沉积量的影响规律。研究结果表明，该制剂中助溶剂和导电剂含量的变化，对制剂粘度和挥发率几乎无影响，而制剂的电导率随着两种助剂含量的增大而增大。两种助剂含量的变化对1%啶虫脒静电喷雾液剂在玉米叶片的正面和反面上的沉积量影响无显著性差异。同时发现使用静电喷雾喷洒1%啶虫脒静电喷雾液剂具有良好的包抄效应。

Abstract: The effect of content variations of cosolvent 1-methyl-2-pyrrolidinone and conductive agent ABS-Ca used in acetamiprid 10ED on conductivity, viscosity and volatilization rate of this formulation has been studied. At the same time, the deposition of the electrostatic spraying was determined utilizing the method of pesticide residue detection. Furthermore, it pointed out influence law of deposition on both sides of corn leaves affected by content variations of cosolvent and conductive agent. The results show that the content variations of cosolvent and conductive agent have no effect on the viscosity and volatilization rate. But there are positive relation between the conductivity of formulation and the content change of two adjuvants. No significant differences were found between the content variations of the two additives and the deposition amount of acetamiprid 10ED on both sides of the maize leaves. It was also found that using electrostatic spraying method has excellent encircling effect.
