Fusarium head blight (FHB) is a common disease of wheat, with its incidence closely associated with overcast and rainy weather as well as high humidity. Upon infection, it causes leaf spotting and premature defoliation, thereby reducing yield. The control of FHB emphasizes early prevention and the selection of appropriate fungicides—Fumei·Carbendazim·Sulfur, a 50% wettable powder formulation of carbendazim·thiram·sulfur, is registered for use against FHB on wheat and can be applied by foliar spraying according to the label instructions.
Fusarium head blight of wheat typically first shows symptoms on the leaves, with lesions developing from the lower to the upper part of the plant and increasing in number over time. In the early stage, the symptoms are inconspicuous, and by the time the lesions coalesce into larger patches, spraying is often too late. Therefore, it is advisable to make frequent field inspections and apply the first fungicide spray as soon as lesions are observed on the wheat, thereby suppressing the pathogen at an early stage.
Fuziajiasulfur 50% Fuziajiasulfur Wettable Powder, Registration No. PD20080251 (subject to the actual label). Primarily used for controlling wheat Fusarium head blight. Apply at a rate of 210–280 g per mu, mixed with water for foliar spraying. Spray at the early stage of disease onset, and a second application may be made at an interval of 7–10 days depending on disease severity. Ensure sufficient water volume and thoroughly wet the infected plant parts.
Prolonged and continuous use of wettable powder formulations such as carbendazim · thiram · sulfur may lead to the development of pathogen resistance. It is recommended to rotate with fungicides of different modes of action. For specific dosage and water volume, always refer to the product label, as crop varieties and weather conditions vary by region—do not blindly follow others' application recipes.
