Technical Field

The invention relates to an agricultural bactericide, in particular to a bactericide composition which is prepared by compounding flumorph and fluopicolide and is used for preventing and treating potato late blight and cucumber downy mildew.

Background

Fluopyram is a pyridine amide bactericide developed by Bayer crop science company in Germany, is widely registered for crops such as vegetables, fruit trees and the like at present, and is used for preventing and controlling important diseases such as downy mildew, epidemic disease, late blight, damping-off and the like caused by oomycete fungi. Is safe to crops and environment, and is particularly suitable for the production of high-quality and green vegetables.

Flumorph belongs to morpholine agricultural bactericide, and is especially effective on peronospora and phytophthora. Has bactericidal effect on Oomycetes, especially those of Peronosporaceae and Phytophthora on grape, potato and tomato, and can be mixed with contact bactericide.

When the fluopicolide single agent or the flumorph is used for a long time, the diseases are easy to generate drug resistance, the problems of increased dosage, reduced prevention effect and shortened lasting period are caused, and the environmental sustainable development is not facilitated.

In most cases, the compounding effect of the pesticide is additive effect, the compounding with real synergistic effect is less, and especially the compounding with very obvious synergistic effect and very high synergistic ratio is less.

Disclosure of Invention

In order to solve the technical problems, the invention provides a bactericide composition of flumorph and fluopicolide. Has obvious synergistic effect through compounding.

The invention provides the following technical scheme:

the bactericide composition takes flumorph and fluopicolide as effective components, and the balance is auxiliary components, the weight ratio of the active components is 3:1, and the active components in the composition account for 5-85% of the mass of the whole preparation.

Further, the auxiliary components comprise a surfactant, a preservative, an antifreezing agent and a suspending aid.

Further, the surfactant may be an emulsifier, a dispersant or a wetting agent; surfactants which may be nonionic or ionic.

The anionic surfactant comprises one or more of sulfonate, sulfate, carboxylate, phosphate, succinate, lignosulfonate and acrylamide acrylic acid copolymer.

The nonionic surfactant comprises one or more of fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene ether, fatty amine polyoxyethylene ether, fatty acid polyoxyethylene ether, acid alcohol ester and polyoxyethylene ether thereof, fatty amide and polyoxyethylene ether thereof, alkanolamide and polyoxyethylene ether thereof, polyoxyethylene polyoxypropylene ether block copolymer, alkyl sodium naphthalene sulfonate fatty alcohol-polyoxyethylene ether and sorbitan fatty acid ester polyoxyethylene ether.
