高分子复合型缓释剂农药的研究

STUDY ON HIGH POLYMER COMPOSITE CONTROLLED RELEASE PESTICIDE

在对进口系列商品剖析的基础上，使用ＰＥ－ＶＡｃ、甲拌磷、毒死蜱及添加剂设计了几组不同的配比、不同粒径的缓释制剂，用自行设计的实验室加速释放试验及活性成份的释放速率测定方法，对两组配方进行了测定．对其中一种进行了田间释放时间试验，结果表明该配方制得的制剂。

On the basis of analysis of a series of pesticide products,we designed seveal groups of the composition, that have different components and granule size,by using PE VAc ,Phorat,Dusban and additives.We accelerated releasing experiment and the method of releasing rate measurement of the active components using the lab which was designed by us,and conduct experiments on both of these two compositions.Meanwhile,we applied one of them to carrying out the relleasing time test in the field.The results showed that the formulations from these two composition have a good controlled releasing property.
