Dinocap is the common name for a mixture of 2,4-dinitro-6-octylphenol crotonate (70-72%) and 2,6-dinitro-6-octylphenol crotonate (28-30%). Dinocap is most commonly sold under the trade names Karathane, Mildex, and Dikar, the latter of which is a mixture of dinocap and mancozeb. Dinocap is registered as a protectant and eradicant fungicide to control powdery mildew diseases on agricultural crops (apples, apricots, cantaloupes, cucumbers, grapes, melons, peaches, pears, pumpkins, raspberries, and squash), nursery stock, ornamentals, and home gardens. The Special Review was initiated on the basis of two oral teratology studies showing developmental malformations. The Agency has reviewed the risks to consumers and homeowners from current dinocap registrations and has concluded that, with the addition of precautionary language concerning the teratogenic potential of dinocap, exposures resulting from use in accordance with label directions provide adequate margins of safety. However, the Agency believes that it is possible to reduce risks to acceptable levels for mixer/loaders and applicators through modifications to the use of dinocap, and proposes certain risk reduction measures.
