Rice blast is a common disease in rice, closely associated with overcast and rainy weather as well as high humidity. Once it occurs, lesions appear on leaves, leading to premature defoliation and reduced yield. The key to controlling rice blast lies in early prevention and selecting the appropriate fungicide—Sulfur·Carbendazim 25% Wettable Powder is registered for rice blast and can be applied by foliar spraying according to the label instructions.
Rice blast typically first shows symptoms on the leaves, with lesions spreading from lower to upper leaves 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, frequent field scouting is essential—apply the first fungicide spray as soon as lesions are observed on the rice plants to suppress the pathogen at its source.
Sulfur · Carbendazim 25% Sulfur · Carbendazim Wettable Powder, Registration No. PD20082591 (subject to the actual label). Mainly used for controlling rice blast. Apply by foliar spray at 320–480 g per mu (667 m²) with sufficient water, starting at the early stage of disease development. A second application may be made at 7–10 day intervals depending on disease severity. Ensure adequate water volume and thoroughly wet the infected plant parts.
Prolonged and continuous use of sulfur-carbendazim wettable powder 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 copy application practices from other areas.
