Abstract

The invention belongs to the field of plant protection and relates to a composition containing polyhexamethylene biguanide or salt of polyhexamethylene biguanide. The composition containing polyhexamethylene biguanide or salt thereof comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is polyhexamethylene biguanide or salt thereof, the active ingredient B is ethylicin or prochloraz or prochloraz salt, ratio of the active ingredient A to the active ingredient B in parts by weight ranges from 1:20 to 20:1, and polyhexamethylene biguanide salt is one of polyhexamethylene biguanide hydrochloride, polyhexamethylene biguanide phosphate and the like. The composition containing polyhexamethylene biguanide or salt thereof can be prepared into a suspending agent, water dispersible granules, wettable powder, emulsion in water, microemulsion and an aqueous solution, can be used for preventing and treating multiple diseases caused by fungi, bacteria and viruses and can be especially used for preventing and treating watermelon fusarium wilt, citrus bacterial canker and anthracnose, rice bakanae disease, pepper virus disease and the like.

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...
