Wheat powdery mildew is a common disease on wheat, closely associated with overcast and rainy weather as well as high humidity. Once it occurs, lesions appear on leaves, leading to premature leaf senescence and reduced yield. The key to controlling wheat powdery mildew lies in early prevention and selecting the appropriate fungicide—Xinyi Jiatuo 36% Thiophanate-methyl Suspension Concentrate is registered for wheat powdery mildew and can be applied by foliar spraying according to the label instructions.
Powdery mildew 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; by the time the lesions coalesce into patches, spraying is often too late. Therefore, it is advisable to make frequent field inspections and apply the first fungicide application as soon as lesions are observed, so as to suppress the pathogen at its source.
Xinyi Jiatuo 36% Thiophanate-methyl Suspension Concentrate, Registration No. PD86116 (subject to the actual label). Primarily controls wheat powdery mildew, and is also effective against citrus scab and mulberry green mold. Dilute at 1,500-fold with water and spray. Apply at the early stage of disease development, and a follow-up application may be made at intervals of 7–10 days depending on disease severity. Ensure sufficient water volume and thoroughly wet the affected plant parts.
Prolonged and continuous use of fungicides such as thiophanate-methyl suspension concentrate can readily induce resistance in pathogenic fungi. It is recommended to rotate with fungicides of different modes of action. For specific dosage rates and water volumes, always refer to the product label. Given variations in crop varieties and local climatic conditions, do not directly adopt application regimens used elsewhere.
