Microcapsule suspension-suspending agent composition and preparation method thereof

Abstract

The invention relates to the technical field of pesticides, and discloses a microcapsule suspension-suspending agent composition and a preparation method thereof. The microcapsule suspension-suspending agent composition is prepared from the following raw materials in percentage by weight: 2.5%-25% of flonicamid, 2.5%-25% of lambda-cyhalothrin, 1%-10% of a synergist, 10%-70% of a pesticide acceptable auxiliary material and the balance of water, and the weight ratio of flonicamid to lambda-cyhalothrin is (3: 1)-(1: 2). The microcapsule suspension-suspending agent composition disclosed by the invention can be used for effectively preventing and treating celery aphids, effectively solving the technical problems of good quick-acting property and short lasting period of the lambda-cyhalothrin, and further solving the problems that the lambda-cyhalothrin is high in toxicity and strong in irritation and easily causes skin pain and itching in the pharmaceutical and using processes; the chemical stability of the effective components of the pesticide can be improved, the usability is improved, pesticide poisoning accidents are reduced, the slow release effect is achieved, and the lasting period is long.
