Anthracnose of citrus trees is a common disease affecting citrus, closely associated with overcast and rainy weather as well as high humidity. Upon infection, it causes leaf spotting, premature defoliation, and reduced yield. The key to controlling citrus anthracnose lies in early prevention and the selection of appropriate fungicides—Lanfeng Qingliang 50% Pyraclostrobin·Thiophanate-methyl Suspension Concentrate is registered for use against citrus anthracnose and can be applied by foliar spraying according to the label instructions.
Citrus anthracnose typically first shows symptoms on the leaves, with lesions spreading from the lower to the upper parts of the tree and increasing in number over time. In the early stage, the symptoms are inconspicuous; by the time the lesions coalesce into larger patches and spraying is initiated, it is often too late. Therefore, frequent field scouting is essential—apply the first spray as soon as lesions appear on citrus trees to suppress the pathogen at its source.
Lanfeng Qingliang 50% Pyraclostrobin · Thiophanate-methyl Suspension Concentrate (SC), Registration No. PD20240806 (subject to the actual label). Primarily used for the control of citrus anthracnose. Dilute at a rate of 1250–1800 times with water and apply as a foliar spray. Begin application at the early stage of disease development, and a second 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 for complete coverage.
Prolonged consecutive use of pyraclostrobin · thiophanate-methyl suspension concentrate 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. Since crop varieties and weather conditions vary by region, do not blindly follow the application protocols used elsewhere.
