Abstract

The invention belongs to the field of plant protection, and relates to a composition containing polyhexamethylene biguanide or its salt. The composition contains two active ingredients, A and B, wherein A is polyhexamethylene biguanide or its salt, and B is Acetoallin or prochloraz or prochloraz salt, the mass-number ratio of the two components A and B is 1:20-20:1, and the polyhexamethylene biguanide salt is polyhexamethylene biguanide hydrochloride, polyhexamethylene biguanide hydrochloride, polyhexamethylene biguanide One of hexamethylene biguanide phosphate etc. The composition can be made into suspension concentrate, water dispersible granule, wettable powder, water emulsion, microemulsion, water formulation, used for preventing and treating various diseases caused by fungi, bacteria and viruses, especially for preventing and treating watermelon wilt and citrus canker Anthracnose, rice bakanae disease, pepper virus disease, etc.

Description

technical field [0001] The invention belongs to the field of plant protection, and in particular relates to a bactericidal composition containing polyhexamethylene biguanide or a salt thereof. The composition is mainly used for preventing and controlling diseases of various plants such as melons, fruits, vegetables, and grain and cotton. Background technique [0002] Polyhexamethylene biguanide, molecular formula (C 7 h 16 N 3 Cl)n is a highly efficient broad-spectrum antibacterial agent, colorless, odorless, low dosage, broad-spectrum and low toxicity, fast action speed, low foam volume, after application, a layer of cations is formed on the surface of the article to inhibit bacteria for a long time, non-toxic. As a cationic fungicide, polyhexamethylene biguanide can quickly adsorb on the surface of bacterial cells in the agricultural field, quickly attack and destroy the cell membrane, inhibit the synthesis of liposomes in the membrane, and cause the apoptosis of the ba...
