Abstract

本发明公开的含有霜霉威盐酸盐和苯醚甲环唑的水悬浮杀菌剂,由以下组分按照重量百分比组成:5%-80%的霜霉威盐酸盐和苯醚甲环唑混合物;1%-10%的分散剂、0.5%-5%的润湿剂、0.1%-1%的增稠稳定剂、1%-5%的防冻剂、0.1%-1%的消泡剂,余量为水;在霜霉威盐酸盐和苯醚甲环唑混合物中,霜霉威盐酸盐和苯醚甲环唑二者之间的配比为0.5-20:1。本发明还公开了该水悬浮杀菌剂的制备方法,将称量好的霜霉威盐酸盐、苯醚甲环唑、分散剂、润湿剂、防冻剂和水投入反应釜中剪切;将剪切好的物料研磨,边研磨边加入称量好的消泡剂;在上步研磨好的物料中加入称量好的增稠剂,继续剪切,即成。本发明的水悬浮杀菌剂,扩大抗菌谱、提高药效、降低用药量、节约经济成本。
The invention discloses a water suspension fungicide containing propamocarb hydrochloride and difenoconazole, prepared from the following components in percentage by weight: 5-80 percent of mixture of the propamocarb hydrochloride and the difenoconazole, 1-10 percent of dispersant, 0.5-5 percent of wetting agent, 0.1-1 percent of thickening stabilizer, 1-5 percent of antifreeze and 0.1-1 percent of foam suppressor and the balance of water. The invention also discloses a preparation method of the water suspension fungicide, comprising the following steps of: putting and shearing the propamocarb hydrochloride, the difenoconazole, the dispersant, the wetting agent, the antifreeze and the water which are weighted in a reaction kettle; grinding the sheared materials while adding the well-weighted foam suppressor; and adding the well-weighted thickening stabilizer to the well-ground materials to continuously shear. The water suspension fungicide of the invention expands an antibacterial spectrum, improves the drug effect, reduces the dosage and saves the economic cost.
