Captan Fungicide is a plant disease control product containing 50.0% active ingredient. It is used to control various fungal diseases on a wide range of crops, including alocasia, apples, apricots, blueberries, cherries, grapes, nectarines, peaches, plums, prunes, strawberries, azaleas, begonias, carnations, chrysanthemums, and gladiolus. The product is intended for outdoor use on various plants. Application methods vary by crop, typically involving spraying at specific rates such as 1 to 2 tablespoons per gallon of water for many fruit and ornamental plants. Users must be careful with compatibility, as Captan can cause injury to certain plants if applied with other chemicals or under specific climatic conditions. It is sensitive to sulfur; do not apply within 14 days of a sulfur application. Handling requires personal protective equipment (PPE), including chemical-resistant gloves, protective eyewear, and long-sleeved shirts/long pants to prevent skin and eye contact. It should be stored in a cool, dry place, away from food or feed. Always follow specific directions for each crop to ensure efficacy and prevent plant injury.
