 The
Interim Risk Management Decision (IRED) for the organophosphate pesticide
dicrotophos (Bidrin®) is now available, according to a Federal Register notice
published on February 5. Dicrotophos is primarily used on cotton and is eligible
for reregistration with certain changes, including a reduction in the total
application rate, a prohibition of aerial applications, and a production cap to
reduce risks to workers and the environment. The IRED states that dicrotophos
fits into its own risk cup, i.e., its individual, aggregate risks from food and
drinking water are within acceptable levels. (EPA OPP Update,
2/12/03).
|
 Based on work by IR-4, the EPA has established
tolerances for the fungicide cyprodinil (Vangard®) on the bushberry group (3
ppm), the caneberry group (10 ppm), pistachio (0.1 ppm), juneberry/lingonberry/salal (3 ppm), and watercress (20 ppm). (Federal
Register, 2/5/03).

 On
February 5, the EPA published a list of pesticide registrations for which
cancellation was requested. Registrations on the list which may affect Florida

264-465), a 24(c) label (FL-850001) for wireworms in sugarcane for Mocap® 10G,
and Griffin’s Boa® (paraquat) herbicide (EPA Reg. # 1812-420). (Federal
