Abstract

The invention relates to a phenazine-1-carboxylic acid (PCA) water suspension which consists of the following raw materials in percentage by weight: 1%-8% of PCA, 1%-5% of an auxiliary suspending agent, 1%-5% of a dispersing agent, 0-5% of a wetting agent, 1%-5% of emulsifier, 0.1%-2% of a thickening agent, 0.5%-3% of a defoaming agent, 2%-10% of an anti-freezing agent, 0-3% of a preservative and the balance of water. The PCA water suspension can be stored for 1-2 years and is easy to flow and free of bleeding, layering and caking, so that the problem of bleeding after storage is solved and the storage, package and transportation costs are reduced; and the PCA water suspension can be diluted with water in any ratio to form uniform suspension liquid, so that the use is convenient and the effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a Shenzimycin aqueous suspension and a preparation method thereof. Background technique [0002] Agricultural chemicals are necessary measures to control the increasingly serious pests and diseases, and play an important role in ensuring the normal production of agriculture. However, unscientific drug use by growers has caused many pathogenic bacteria to develop high drug resistance, which has reduced the level of chemical agents to control diseases, insect pests and weeds. Under such circumstances, in order to control diseases, insect pests and weeds, growers will increase the amount of pesticides, increase the frequency of application, and use a large amount of highly toxic pesticides. This increases the cost of planting agricultural products and aggravates the pollution of pesticides to food and the environment. Therefore, high-efficiency, low-toxic, safe, and environmental...
