Abstract

The invention relates to a compound bactericide of chitosan oligosaccharide and dioctyl divinyltriamino glycine acetate. The compound bactericide is characterized by being prepared from 1 to 45 mass percent of chitosan oligosaccharide and 1 to 50 mass percent of dioctyl divinyltriamino glycine acetate which serve as active ingredients of a preparation and the balance of a pesticide aid, a solvent or a carrier, wherein the bactericide composition can be water aqua, a suspending agent, wettable powder and aqueous dispersion granules. The compound bactericide is used for preventing and controlling rice blast. By the compound bactericide, the pesticide resistance of pathogene is overcome and delayed, and the disease resistance of crops is improved; and the compound bactericide has a synergistic effect, and is safe in application and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a compound bactericide of chitosan oligosaccharide and octocalid acetate. Background technique [0002] Rice blast is one of the important diseases of rice. Together with rice sheath blight, rice false smut, and rice virus disease, it is called the four major diseases of rice. The disease is widely distributed and occurs in more than 80 countries and regions around the world. It also occurs in the north and south rice regions of my country. In areas where the disease is endemic, the yield is generally reduced by 10% to 20%, and in severe cases it can reach 40% to 50%. Especially heavy fields may even fail to harvest. [0003] At present, the prevention and control of rice blast mainly takes measures such as breeding resistant varieties, chemical control and strengthening cultivation management. Most of the disease-resistant varieties are vertically resistant varieties based ...
