Cucumber anthracnose keeps recurring? Use sulfur·thiophanate-methyl this way to suppress the pathogen at its source.

Anthracnose of cucumber is a common disease on cucumber, and its occurrence is closely related to overcast and rainy weather and high humidity. After infection, lesions appear on leaves, leading to premature defoliation and reduced yield. The key to controlling cucumber anthracnose lies in early prevention and the selection of targeted fungicides—Sulfur·Thiophanate-methyl 50% Sulfur·Thiophanate-methyl SC is registered for use against cucumber anthracnose and can be applied by foliar spraying according to the label instructions.

Anthracnose of cucumber typically first shows symptoms on the leaves, with lesions developing 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 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 cucumber leaves, so as to suppress the pathogen at its source.

Sulfur·Thiophanate-methyl 50% Sulfur·Thiophanate-methyl Suspension Concentrate, Registration No. PD20082660 (subject to the actual label). Primarily used for controlling cucumber anthracnose. Apply at a rate of 150–300 mL per mu, diluted with water and sprayed. Spray at the early stage of disease incidence, and a supplementary 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 consecutive use of sulfur·thiophanate-methyl suspension concentrate can easily lead to pathogen resistance. It is recommended to rotate with fungicides of different mechanisms of action. For specific dosage and water dilution, always follow the product label. Since crop varieties and weather conditions vary by region, do not blindly copy others' prescriptions.
