Problems solved by technology

[0004] Although my country's pesticide microcapsule suspension has been greatly developed, there are still many problems to be solved urgently, such as: some capsule wall material monomers have high toxicity, are difficult to degrade, and the decomposition products may be harmful to the environment (resin decomposition for in situ reaction will produce formaldehyde); it will make some refractory pesticides last longer and cause harm to the environment; the thickness of the capsule wall is not easy to control during the preparation process, which affects the release of pesticides, etc. These problems restrict the suspension of pesticide microcapsules agent development

Abstract

The invention belongs to the field of pesticide preparations, and particularly relates to an acetamiprid microcapsule suspending agent which comprises the following components in parts by weight: 0.1to 10 part of acetamiprid, 1 to 10 parts of polylactic acid, 0.5 to 2 part of polyvinyl alcohol, 5 to 30 parts of an organic solvent, 1 to 10 parts of an emulsifier, 1 to 15 parts of a dispersing agent, 0 to 10 parts of an auxiliary agent and the balance of water, totaling 100 parts. The microcapsule suspending agent prepared by the invention is environment-friendly, and the action time of acetamiprid can be prolonged.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to an acetamiprid microcapsule suspension. Background technique [0002] Conventional pesticide formulations such as emulsifiable concentrates, powders, wettable powders, etc. have gradually shown disadvantages such as high toxicity, high residues, and poor environmental compatibility, which are inconsistent with people's pursuit of green environmental protection. These traditional dosage forms will be eliminated by new green environmental protection dosage forms. At present, the research and development of dosage forms is developing towards the direction of low toxicity and non-toxicity of highly toxic pesticides. The main new dosage forms include water emulsion, suspension concentrate, microemulsion, water dispersible granule, sustained release agent, etc. [0003] Microcapsule suspension is to wrap the pesticide (capsule core) in a tiny container formed by the capsule wall ...
