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 leaf senescence, thereby reducing yield. The control of Fusarium head blight emphasizes early prevention and the selection of targeted fungicides—Lanfeng Baihu 17% pyraclostrobin + epoxiconazole suspension concentrate is registered for the management of Fusarium head blight 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 spreading from the lower to the upper parts 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 first observed on the wheat, so as to suppress the pathogen at its source.
Lanfeng Baihu 17% Pyraclostrobin + Epoxiconazole Suspension Concentrate (SC), Registration No. PD20200736 (subject to the actual label). Primarily controls wheat Fusarium head blight (scab), and also provides secondary control of wheat rust and northern corn leaf blight. Apply at 45–65 mL per mu (667 m²) diluted with water as a foliar spray. 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 consecutive use of pyraclostrobin and similar fungicides can readily induce 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. Since crop varieties and weather conditions vary by region, do not blindly copy application regimens used elsewhere.
