Microthiol Disperss is a micronized wettable sulfur fungicide containing 80.0% active sulfur. It is used to control various fungal diseases across a wide range of crops, including vegetables, fruits, nuts, turf, and ornamentals. The product works by providing a protective layer on plant surfaces. It can be applied via handheld sprayers, mechanical sprayers, or chemigation systems. For aerial applications, the label provides specific rates for field and orchard settings. When using chemigation, the product is designed to disperse instantly into the water stream. Key handling notes include avoiding contact with skin or clothing, and being cautious of wind speed to prevent drift. It is incompatible with certain materials like copper fungicides and organic fertilizers. Always follow specific dilution rates for the target crop and application method to ensure efficacy and prevent phytotoxicity, especially in high temperatures.
