Abstract

The invention relates to a profenofos microcapsule suspension concentrate which comprises the following components by weight percent: 5-15% of profenofos, 1-2% of solvent, 1.5-2.5% of capsule wall material, 3-5% of wetting dispersant, 2-3% of anti-freezing agent, 0.3-1% of thickening agent, 0.1-0.5% of organic silicon defoaming agent, 1-3% of curing agent and the balance of water, wherein the total weight percent is 100%. The water is used for replacing a large quantity of organic solvents, the aromatic organic solvent is not used or the usage amount of the aromatic organic solvent can be reduced as far as possible, on the one hand, the environmental pollution is reduced, and the profenofos microcapsule suspension concentrate is safe to operation staff, on the other hand, the valid period is prolonged, the medication frequency and the medication quantity can be reduced, and the using efficiency of agricultural chemicals can be improved.

Description

technical field [0001] The invention relates to an insecticide, in particular to a profenofos microcapsule aqueous suspension and a preparation method thereof. Background technique [0002] Profenofos is a three-component asymmetric high-permeability broad-spectrum organophosphorus insecticide. It has contact and stomach poisoning, fumigation, and direct penetration effects. It can directly penetrate into leaves and insects, and completely kill lurking in leaves (back) , in paddy fields, in fruits and pests that drill into stalks. Profenofos is a phosphorothioate insecticide containing n-propylthio group in its molecule. It has a broad insecticidal spectrum, is easy to biodegrade, and exhibits high biological activity against resistant pests. It can be used to control pests such as cotton bollworm, stem borer (borer), meadow borer, rice weevil, leafminer, gray planthopper, negative mudworm, borer, aphid and other pests on rice, cotton, fruit trees, vegetables and other crop...
