Sterilization composition containing fluopyram and fenhexamid

Abstract

The invention discloses a sterilization composition containing fluopyram and fenhexamid. Effective active ingredients consist of a first active ingredient fluopyram and a second active ingredient fenhexamid; a weight ratio of the first active ingredient to the second active ingredient is (1:80) to (60:1), preferably is (1:60) to (40:1) and the most preferably is (1:30) to (20:1). The composition can be prepared into preparations of wettable powder, water dispersible granules, a suspension agent, suspoemulsion, emulsion in water, microemulsion, aqueous capsule suspension, an aqueous capsule suspension-suspension agent, a dispersible oil suspension agent and dry flowable, which are allowed agriculturally. The sterilization composition is reasonable in component and good in sterilization effect; the activity and the sterilization effect of the composition are not simple overlapping of the activity of each component; compared with an existing single preparation, the sterilization composition not only has the obvious sterilization effect, but also has an obvious synergistic effect and has high safety for crops. The sterilization composition has obvious prevention and treatment effects on botrytis cinerea, brown rot, powdery mildew, early blight and venturia inaequalis of the crops.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of a first active ingredient fluopyram, a second active ingredient fenhexamid and an auxiliary agent, and belongs to the technical field of compound pesticides. Background technique [0002] Fluopyram, the English name is fluopyram, the chemical name is N-{2-[3-chloro-5-(trifluoromethyl)-2-pyridyl]ethyl]-α,α,α-trifluoro- O-toluamide is a new type of benzamide fungicide, which acts on the complex II of the mitochondrial respiratory electron transport chain [that is, succinate dehydrogenase (succinate dehydrogenase, SDH) or succinate coenzyme Q reductase (succinate- coenzymeQreductase, SQR)], which inhibits mitochondrial respiration by hindering the electron transfer of succinate dehydrogenase in the respiratory chain. It is mainly used to control diseases caused by cyst fungi on broad-leaved crops. It has a good control effect on various diseases such as powdery mildew and target s...

Problems solved by technology

[0004] After searching, the applicant found that there is currently no literature report on the mixture of fluopyram and fenhexamid for the prevention and treatment of plant fungal diseases. Further tests found that the compounding of fluopyram and fenhexamid with different mechanisms of action , has unexpected effects, and has a good control effect on gray mold, brown rot, powdery mildew, early blight, and scab.
