                             Cyprodinil (PC 28802)
 First Registered: 1998 (No RED/TRED)
 Registrations: One technical (Syngenta), 4 end use products, 5 SLNS

Use Information: 
 Cyprodinil is a selective fungicide with registered uses on almonds, citrus, grapes, kiwi, pistachios, pome fruits, stone fruits, tropical fruits, beans, berries, brassica leafy vegetables, carrots, chickpeas, cucurbits, herbs, leafy vegetables, leaves of root and tuber vegetables, bulb vegetables, root vegetables, ornamentals, strawberries, tomatoes, and watercress. 
 Also applied to ornamental landscaped areas. 
 NOT registered for homeowner use and no products registered for application to residential areas. 
 Available as a water dispersible granule and an emulsifiable concentrate. 
 Can be applied in liquid form either as a ground or aerial spray. 
Human Health Risks:
 Highest dietary values for food + water are children 1-2 years old at 8.6% aPAD and 86% of cPAD
 No residential, occupational, or aggregate risks of concern.
Ecological Risks:
 All registered used may result in risk to listed (and a few uses to non-listed) aquatic freshwater invertebrates. Acute RQs ranged from 0.13 to 0.74 for all uses except watercress, with an RQ of 22.6 (LOC 0.5).  Chronic RQs ranged from 0.7-18.2 (LOC 1). Estuarine/marine invertebrates had acute RQs ranging 0.49-88.82 and chronic RQs from 1.8-78.4. Watercress RQs are an order of  magnitude higher than the use with the next highest RQs.
 Aquatic RQs do not account for reductions in runoff resulting from spray buffers (75ft ground, 150ft aerial) or from 10ft vegetative buffer strips. 
 Direct application to water such as for the use on watercress also result in risk to listed freshwater fish (RQ 0.33, listed LOC 0.05), non-listed estuarine/marine fish (acute RQ 0.58, chronic 3.21, LOC 0.5 for acute, 1 for chronic) and listed aquatic vascular plants (RQ 13.39, LOC 1).  
 The chronic LOC of 1 was exceeded for small, medium and large mammals feeding on short grass for every application rate modeled (RQs up to 2.6). 
 No other risk to listed or non-listed species identified to terrestrial taxa (birds, plants, and insects) from any use or application rate of cyprodinil.
