The present invention relates to the preparation of novel solid pesticide formulations which, after application, provide a dry, coherent deposit of the pesticidal agent on the target, resulting in increased residual activity and greater efficacy when applied to various agricultural products, especially food crops. This enhanced residual activity results from formulation of the pesticidal agent with 10-75% by weight of a polyvinylpyrrolidone polymer or copolymer and application of the formulation to the target.
本发明涉及新型固体农药制剂的制备,施用该制剂后,杀虫剂会在目标物上形成干燥、连贯的沉积物,从而在施用到各种农产品,特别是粮食作物上时,可提高残留活性和药效。将杀虫剂与 10-75% (按重量计)的聚乙烯吡咯烷酮聚合物或共聚物配制成制剂并施用到目标物上,可提高残留活性。
