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 present invention is the field of pesticide preparations, involving a method of preparation of agricultural pesticides, which specifically involves a pesticide suspension (SC) and its preparation methods containing tapeworm. Background technique [0002] The spraying of agricultural chemical agents is an essential measure to govern the increasingly serious pests and pests, which has played an extremely important role in ensuring normal agricultural production.In recent years, as the unscientific medications of the growers have caused many pathogenic bacteria to highly resist the extensive application of pesticides, which will inevitably reduce the level of prevention and treatment of chemicals to diseases and insect pests.In order to treat diseases and grass pests, growers have to increase the amount of pesticides, increase the number of medications, and use a large amount of toxic pesticides, which not only increases the cost of planting agricultural p...
