Problems solved by technology

Bacterial diseases have the characteristics of various infection routes, fast transmission speed, and difficult control, which seriously restrict the healthy and orderly development of the crop industry
[0007] At present, for the prevention and control of bacterial diseases of crops, the main commercial agents are antibiotics, copper preparations, and a small amount of chemical agents such as thiacumazole, but these drugs usually have poor antibacterial effects and low antibacterial rates against bacterial blight of melons. Sexual angular spot disease also has the problem that the control effect is not high, and the disease index after drug treatment is still high. In addition, long-term use has certain problems such as drug resistance risk and drug damage risk. The degradation products remain in the environment for a long time, and are toxic to the environment and animals. Residues, compared to vegetables with higher food safety requirements, a new type of broad-spectrum and environmentally friendly bactericide is more urgently needed

Abstract

The invention provides a compound bactericide containing bronopol and amino-oligosaccharin and a preparation method thereof, the mass ratio of bronopol to amino-oligosaccharin is 25-60: 0.4-0.8. The bromonol and the aminooligosaccharide have synergistic effect within a certain compound proportion range, have chemical protection effect on crops in the actual use process, and obviously improve the prevention and control effect of the crops on bacterial diseases compared with single dose alone, the compound bactericide has wide sterilization range, is used for prevention and control of melon bacterial gummy stem blight, field melon bacterial angular leaf spot and most bacteria and fungi on vegetables, and has obvious prevention and treatment effects on pseudomonas, acidovorax, xanthomonas, erwinia and coryneform bacteria.

Description

technical field [0001] The invention relates to the field of biopesticide sterilization and its preparation, in particular to a compound bactericide containing bronopol and amino oligosaccharin and a preparation method thereof, which is applied to bacterial blight of melon and bacterial horn of field melon Spot disease and the prevention and control of most bacteria and fungi on vegetables. Background technique [0002] Bronopol, chemical name 2-bromo-2-nitro-1,3-propanediol (2-Bromo-2-nitro-1,3-propanediol), chemical structural formula is: [0003] [0004] Also known as Bropol, it was used in cosmetic preservatives, milk preservation and antisepsis and medical trauma treatment agents in the early days. In recent years, it has been widely used in water treatment, medicine, detergent, pesticide and other industries. It is a high-efficiency broad-spectrum bactericide with high bactericidal activity and low concentration. It has no irritation and no allergic reaction to hu...
