Abstract

The invention discloses a sterilization composition containing propamidine and chitosan oligosaccharides, wherein the mass ratio of the propamidine to the chitosan oligosaccharides is 4:1-8:1. The composition can be missible oil, a microemulsion, a soluble liquid or an aqua, can be used for controlling fruit or vegetable crop diseases, and can effectively control cucumber fusarium wilt, cucumber downy mildew, tomato gray mold and the like. The composition has the advantages of environmental protection, wide application range, low cost and good effect.

Description

technical field [0001] The invention relates to a pesticide preparation and preparation thereof, in particular to a fungicidal composition containing propaneamidine and chitosan oligosaccharide, which is suitable for preventing and controlling plant fungal diseases such as cucumber wilt, cucumber downy mildew, tomato gray mold and the like. Background technique [0002] 1. Propanamidine [0003] Propamidine, whose chemical name is 1,3-bis(4-amidinophenoxy)propane, is a systemic fungicide that can be absorbed, distributed and metabolized in plants, and has dual effects of protection and treatment. The drug is mainly used to prevent and control various plant diseases of vegetables, fruit trees and commercial crops in the field and in the greenhouse. According to my country's pesticide toxicity classification standards, propaneamidine fungicide is a low-toxic fungicide, which is safe for environmental biology. [0004] According to the data search done by the applicant, the c...
