Abstract

The invention relates to a benziothiazolinone water suspension and a preparation method thereof. The benziothiazolinone water suspension is prepared from the following components by weight percentage: 1.6-50% of benziothiazolinone, 0.3-5% of defoamer, 10-20% of wetting and dispersing agent, 0-5% of penetrating agent, 0.3-5% of thickener, 10-80% of water, 1-10% of anti-freezing agent and pH regulator which adjusts the pH value to 6.0-9.0.

Description

technical field [0001] The invention belongs to the technical field of fungicides, and more specifically relates to a novel thiamethondone aqueous suspension and a preparation method thereof. Background technique [0002] Benziothiazolinone (benziothiazolinone), other names are: bacteria kill, chlorterimazole, belongs to organic heterocyclic compounds, is a high-efficiency, low toxicity, broad-spectrum, systemic anti-corrosion, anti-mold fungicide, with a bactericidal spectrum Wide range, low recurrence rate, rain-resistant, non-toxic and side effects to humans and animals, etc., it has a significant control effect on plant rot, root rot, anthracnose, downy mildew and other fungal diseases. Common preparations are 0.8%, 1.5% water emulsion. This is the earliest new pesticide variety with independent intellectual property rights in my country. It was exclusively developed by Shaanxi Xidahuate Technology Industry Co., Ltd. and officially registered in the Drug Control Institu...
