Abstract

The invention provides a compound fungicide for preventing and treating fungal diseases of wheat, which is composed of active ingredients, fillers and auxiliary agents, wherein the active ingredients are composed of triazole fungicides and protective agents. The compound preparation for preventing and treating fungal diseases of wheat according to the present invention has remarkable synergistic effect, and the control effect is as high as 90.5%, which is obviously higher than that of a single preparation, and better than conventional medicines 50% carbendazim wettable powder and 50% thiram wettable powder , 6% Likexiu suspension seed coating agent, 5% hexaconazole microemulsion and 6% pentafloxacin wettable powder. The compound preparation has good quick-acting effect and long-lasting effect, has many action mechanisms and sites, and can effectively delay the occurrence and development of drug resistance of pathogenic bacteria; Wide, high biological safety.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a compound fungicide for preventing and treating fungal diseases of wheat and its application. Background technique [0002] Wheat is an important food crop in my country. Sheath blight, powdery mildew, rust, root rot and take-all are the main fungal diseases that affect my country's wheat production. In recent years, they have become more serious and have caused heavy losses of wheat. In production, there is a lack of high-resistant wheat varieties or the loss of disease resistance of wheat varieties. Chemical control is still the main means of preventing and controlling these types of diseases and an important guarantee for high wheat yield. [0003] Wheat sheath blight is a soil-borne disease that can infect wheat before grain filling, and its infection parts are mainly in leaf sheaths and stems. The usual control method is to use chemical seed dressing in the autumn sowing period. ...
