Abstract

A provided sterilization composition with synergic effect comprises an active component A and an active component B with the mass ratio of 1:50 to 50:1; the active component A is polyhexamethylene biguanidine or its agriculturally-acceptable salt compounds; and the active component B is one selected from cyprodinil, epoxiconazole, benthiavalicarb-isopropyl, zoxamide, azoxystrobin, prothioconazole, difenoconazole, fenamidone, polyoxin, iprodione, acibenzolar, dithianon, pyraclostrobine, trifloxystrobin, picoxystrobin, fluazinam, thifluzamide and dimethomorph. Test results show that the provided above sterilization composition is obvious in synergic effect, and more importantly, the usage amount is less and the usage cost is reduced. By compounding sterilization agents with different action mechanisms and action manners, the usage amount of a single sterilization agent is effectively reduced, and extremely good effect is provided for expanding sterilization spectrum, delaying fungi resistance, improving controlling effect and other aspects.

Description

Technical field [0001] The invention belongs to the field of agricultural plant protection, and particularly relates to a bactericidal composition with improved performance, and specifically to a bactericidal composition contained therein. Background technique [0002] Polyhexamethylene biguanide is a broad-spectrum antibacterial agent developed by the British company Aveciago and recognized as the safest and most effective in the 21st century. It is colorless and odorless, low in dosage, broad-spectrum and low toxicity, fast in action, low in foam, and After being able to form a layer of cations on the surface of the article for long-term bacteriostasis, and will not cause the formation of antibacterial bacteria, its safety is recognized by the US FDA and EPA, and its semi-lethal dose for mice is LD50> 5000mg / kg, which is actually non-toxic. Because polyhexamethylene biguanide is used as a cationic fungicide in the agricultural field, it can quickly adsorb on the surface of b...
