4%啶虫脒·高氯微乳剂配方的研究与室内毒力测定

Study of 4% Acetamiprid·Beta-cypermethrin Micro-emulsion

啶虫脒和高效氯氰菊酯都是生物活性很高的杀虫剂。为了在提高其杀虫活性的同时降低有效成分的含量和减少制剂中有机溶剂的用量,介绍了一种新剂型4%啶虫脒·高氯微乳剂。简要叙述了该剂型的特点、配方选择、贮存稳定性、确立了较佳的配方组成及质量控制指标。采用桃蚜作试虫进行杀虫活性测定。4%啶虫脒·高氯微乳剂与4%啶虫脒·高氯乳油、啶虫脒乳油、高氯乳油药效作了对比。结果表明,该微乳剂具有明显的增效作用,同时该微乳剂品种成本低、药效好、质量稳定,使用安全、社会效益显著。

Acetamiprid and beta-cypermethrin both are high active pesticide. In order to improve insecticidal activity and reduce the dosage of organic solvent, it introduced the 4% acetamiprid beta-cypermethrin ME which is the new insecticidal formulation. The characteristic of this formulation, storage stability and insecticidal activites were summarized in this paper. 4% acetamiprid beta-cypermethrin EC had high insecticidal activity compared with acetamiprid EC and beta-cypermethrin EC. The new formulation also had the advantage of low cost, good effect, stable quality, safe and sociological benefits.
