Uses
Captafol (CAS NO.2425-06-1) is used to control almost all fungal diseases of plants except powdery mildews. Although no longer sold in the United States, elsewhere it is used widely to control diseases on apples, citrus fruits, tomatoes, cranberries, potatoes, coffee, pineapples, peanuts, onion, stone fruits, cucumbers, blueberries, prunes, watermelons, sweet corn, wheat, barley, oilseed rape, leeks, strawberries, cotton, peanuts and rice.

Specification
Captafol (CAS NO.2425-06-1) is a white crystalline solid with a slight, but pungent odor. It practically insoluble in water and only slightly soluble in organic solvents. Technical Captafol is a wettable light tan powder that is used as a fungicide. Inhaled dust irritates the respiratory tract. Irritates skin and damages eyes. Acute oral toxicity in humans is low. Not persistent in the environment (decomposes with a half-life of 11 days in the soil). Highly toxic to fish and other aquatic organisms. Captafol is non-flammable but, on heating, may decompose to generate toxic fumes, such as sulfur oxides, hydrogen sulfide, hydrochloric acid, and phosgene. Stable at room temperature when dry but readily hydrolysed, especially in an alkaline environment. CAPTAFOL and mixtures containing high concentrations of Captafol may react violently with alkali. It incompatible with acids, acid chlorides, acid anhydrides, and strong oxidizing agents. Sulfhydryl compounds such as glutathione and cysteine cause a rapid chemical decomposition.
International trade in Captafol is regulated by the Rotterdam Convention.
