Problems solved by technology

[0003] At present, trimorpholine fungicides are mainly wettable powders and emulsifiable concentrates. During the preparation and use of wettable powders and emulsifiable concentrates, human health and environmental pollution are relatively large. Low yield, short effective period, and difficult to mix, it is a dosage form that is on the verge of being eliminated in the development of pesticides, and the packaging is inconvenient, and storage and transportation are complicated

Abstract

The invention provides a bactericidal agent with tridemorph, which is aqueous emulsion which is prepared by tridemorph, and proper auxiliary agent and water, wherein the auxiliary agent comprises emulsifying agent, dispersed agent, dissolvent, defoaming agent, deicing fluid and co-emulsifier and the like. The bactericidal agent of the invention can be extensively applied to preventing and curing resistant diseases such as powdery mildew on vegetables, wheets, and cucumbers, and leaf spot on bananas.

Description

technical field [0001] The invention relates to a fungicide, in particular to an agricultural fungicide containing tridemorph. Background technique [0002] Tridemorph is a broad-spectrum systemic fungicide with dual functions of protection and treatment. It can be absorbed into the plant through the roots, stems and leaves of the plant, and move upward in the xylem, but only in the wound. Slight degree of transfer, so trimorpholine is only slightly affected by climatic factors after application, and maintains a long residual effect period. It is mainly used to prevent and control cereal powdery mildew and banana leaf spot, and other fungal diseases, such as rubber trees. White, red, brown root disease, powdery mildew, coffee eye spot disease; cake disease of tea leaves; powdery mildew of melons; powdery mildew of flowers and trees and so on also have good control effect. Therefore, it has a good control effect on the control of powdery mildew on vegetables, wheat, cucumber...
