Abstract

The invention discloses indoxacarb water suspension concentrate and a method for preparing the same. The indoxacarb water suspension concentrate comprises, by weight, 10-25% of indoxacarb active compounds, 2-7% of dispersing agents, 1-7% of wetting agents, 1-5% of additional suspension concentrate, 1-8% of emulsifiers, 1-5% of thickeners, 0.5-5% of defoaming agents, 1-8% of antifreezing agents, 0.5-5% of preservatives, 0.5-5% of pH (potential of hydrogen) regulators and the balance water. The indoxacarb water suspension concentrate and the method have the advantages that the water suspension concentrate prepared by the aid of the method is free of dust, low in toxicity and safe for operators and users, optional organic solvents are omitted, and accordingly problems of flammability, explosiveness and intoxication during production can be solved; the water is used as a medium, so that environmental pollution can be reduced, and the indoxacarb water suspension concentrate is low in cost; the indoxacarb water suspension concentrate which is a pesticide preparation conforms to the high-content and environment-friendly preparation processing trend, is a pollution-free pesticide and accordingly has a broad application prospect.

Description

Technical field [0001] The invention belongs to the field of pesticide preparations and relates to a preparation method of agricultural pesticides, specifically a pesticide aqueous suspension (SC) containing indoxacarb and a preparation method thereof. Background technique [0002] The spraying of agricultural chemicals is a necessary measure to control increasingly serious pests and diseases, and plays an extremely important role in ensuring normal agricultural production. In recent years, the unscientific use of pesticides by growers has caused many pathogenic bacteria to become highly resistant to widely used pesticides, inevitably reducing the level of chemical pesticides in the control of diseases, insect pests and weeds. In order to control diseases, insect pests and weeds, growers have to increase the amount of pesticide application, increase the frequency of pesticide application, and use a large amount of highly toxic pesticides, which not only increases the cost of...
