Abstract

The invention provides a compound bactericide which has better prevention and treatment roles on various scab, rust, leaf spot, powdery mildew and the like. The active ingredients are ethirimol and 2-cyano-3-amino-3-phenylancryic acetate, the preferential content of the ethirimol is 5-40 percent, and the preferential content of the 2-cyano-3-amino-3-phenylancryic acetate is 10-40 percent. The compound bactericide overcomes the defects of the original monotonous ingredient, and the prevention effect is significant and obviously higher than a single preparation. The compound bactericide is characterized by quick acting, broad spectrum, longer lasting period and the like, the preparation process is simple, the cost is low, and the compound bactericide can be prepared into emulsion concentrate, micro-emulsion, emulsion in water, suspension, wettable powder, water dispersible granules and other conventional preparations.

Description

Technical field [0001] The invention relates to the field of pesticides, in particular to a compound fungicide. Background technique [0002] Fungal diseases are one of the main reasons for crop yield loss, and 80% of crop diseases are caused by pathogenic fungi. Several or even dozens of fungal diseases can be found on one crop. So far, the control of crop fungal diseases has mainly been the use of chemical fungicides. However, the cost of chemical fungicides is relatively high, and most of the agents eventually lead to the resistance of pathogenic bacteria, and their residual toxicity also causes environmental pollution and other problems. Therefore, the solution to drug resistance is to use different modes of action of the drug compound, by changing the site of action, to better overcome the problem of drug resistance, under the premise of increasing efficiency and increasing production, while reducing the amount of use and environmental impact Many problems such as polluti...
