Fluopyram and fenpyrazamine-containing sterilization composition

Abstract

The invention discloses a fluopyram and fenpyrazamine-containing sterilization composition and application thereof. Effective active components comprise a first active component fluopyram and a secondactive component fenpyrazamine; a weight ratio of the first active component to the second active component is (1: 80) to (60: 1), preferably (1: 60) to (40: 1), and most preferably (1: 30) to (20: 1). The composition can be prepared into agriculturally permissible wettable powder, water dispersible granules, suspension, suspoemulsion, emulsion in water, microemulsion, capsule suspension, capsulesuspension-suspension agent, dispersible oil suspension agent and a dry suspension agent. The composition is reasonable in constitution and good in sterilization effect; furthermore, the activity andthe sterilization effect of the composition are not simply superposed by the activities of all the components. Compared with an existing single preparation, the fluopyram and fenpyrazamine-containingsterilization composition has an outstanding synergistic effect in addition to the outstanding sterilization effect, and is high in safety to crops. The fluopyram and fenpyrazamine-containing sterilization composition has obvious prevention and treatment effects on gray mold, brown rot, sclerotinia sclerotiorum, venturia inaequalis and powdery mildew of the crops.

Description

technical field [0001] The invention relates to a bactericidal composition, which is composed of the first active ingredient fluopyram, the second active ingredient fenpyrafen and auxiliary agents, 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...

AI Technical Summary

Problems solved by technology

[0004] After searching, the applicant found that there is no bibliographical report on the mixing of fluopyram and fenpyrafen to prevent and control plant fungal diseases, and it was further found through experiments that fluopyram and fenfluram, which have different mechanisms of action, Compound, with unexpected effect, has a good control effect on fungal diseases such as gray mold, brown rot, sclerotinia, scab and powdery mildew, with obvious synergistic effect, less dosage and lower control cost , safe for crops
