Abstract

The invention relates to a pyriproxyfen microcapsule suspending agent and a preparation method and application thereof.The pyriproxyfen microcapsule suspending agent comprises a microcapsule core, the microcapsule core is pyriproxyfen, the content of pyriproxyfen in the pyriproxyfen microcapsule suspending agent is 1%-10% by mass, the microcapsule suspending agent further comprises a microcapsule wall, and the microcapsule wall is made of water. The capsule wall of the microcapsule is made of polyurea or polyurethane, and the polyurea is generated by carrying out polymerization reaction on a polymeric monomer isocyanate and a polymeric monomer polyamine; the polyurethane is generated by polymerization reaction of a polymeric monomer isocyanate and a polymeric monomer polyol. The pyriproxyfen microcapsule suspending agent further comprises a solvent, an emulsifying agent, a dispersing agent, an anti-freezing agent, a thickening agent, a preservative, a defoaming agent and water. The pyriproxyfen microcapsule suspending agent provided by the invention is good in performance, has a longer lasting period compared with a conventional dosage form, can reduce the prevention and control cost of agricultural pests, and has a good popularization value.

Description

technical field [0001] The invention relates to the field of pesticide formulations, and in particular, the application relates to a microcapsule suspension of fenfluroprop and its preparation method and application of pest control in agriculture. Background technique [0002] In agricultural production, the prevention and control of pests and diseases is very important, but in the actual application of pesticides, there are often unscientific applications such as excessive spraying and liquid drift, resulting in the development of pest resistance, increased drug costs, and harmful target crops, etc. Therefore, the development of efficient, low-toxic and low-cost pest control methods has always been an important research and development direction. [0003] Linfenafen is a new type of insecticidal compound disclosed in patent CN1860874A, which was developed from triflufenac (acetamiprid) as the leading compound, and exhibits good insecticidal activity. The structural formul...
