Bactericidal composition containing fenamidone and prochloraz and application

Abstract

The invention relates to a bactericidal composition containing fenamidone and prochloraz and application, belonging to the technical field of pesticides. An effective component is a compound in which the weight ratio of fenamidone to prochloraz is (1:40)-(40:1); the total mass of fenamidone and prochloraz which serve as the effective components in the preparation accounts for 1-80 percent of the mass of the whole preparation. The composition can be prepared into agriculturally allowable suspension, a water dispersible granule, wettable powder, emulsifiable concentrate, emulsion in water, a micro emulsion and the like. The components are reasonable, the sterilization effect is good, and the medicine use cost is low; the activity and the sterilization effect of the bactericidal composition are not simply stacked by the activities of all the components; compared with the conventional single drug, the bactericidal composition has an outstanding sterilization effect and an outstanding synergism effect; generation of resistance can be relieved, and the quantity of preparation residues is small; pollution to crops is avoided, the safety is high, and a requirement on the safety of a pesticide preparation is met.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a fungicidal composition whose main active ingredients are imidaclofen and prochloraz, and a use method and application thereof. Background technique [0002] Fenamidone, molecular formula: C17H17N3OS, chemical name: (S)-1-anilino-4-methyl-2-methylthio-4-phenylimidazolin-5-one (IUPAC); (S )-3,5-dihydro-5-methyl-2-methylthio-5-phenyl-3-anilino-4H-imidazol-4-one (CA). Its structural chemical formula is [0003] [0004] Imidazolone is a novel imidazolone fungicide discovered by Aventis (now Bayer). It is optically active, and all its bactericidal effects are derived from the S-enantiomer. The mechanism of action of imidazolidone and oxafluconone and methoxyacrylate fungicides is similar. It inhibits the respiration of line bold by preventing the electron transfer between coenzyme Q-H2 and cytochrome C oxidoreductase. Ketone has protective and therapeutic effects, and has ant...
