The intent of this network is to inform interested parties of recent or
impending pesticide use cancellations, tolerance revocations, and other items
of agricultural interest.  To the best of our knowledge, the uses mentioned
here, unless otherwise indicated, will not appear on any label registered by
the USEPA after those uses are canceled.  We recommend that you express any
concerns or questions you have to the contact mentioned below or to your
NAPIAP State Liaison Representative.  If you wish to contact us at USDA, our
phone number is (301) 504-8846, and our fax number is (301) 504-8063.

The following uses of malathion are currently unsupported and expected to be

For the unsupported greenhouse uses listed above, the pesticide tolerances 
are being defended.  However, other studies or a commitment to register may 
be necessary in order to maintain these uses.

Most of the supported uses will be labeled on products containing the 57% 
emulsible concentrate (EC) formulation.  Dust (D) formulations are being 
canceled except for date and stored grain uses.  Ultra low volume (ULV) 
formulations are being limited to alfalfa, clover, grain sorghum, rice, 
wheat, blueberries, cherries, beans, and grasses.  Wettable powders (WP) are 
being limited to uses on apples, pears, quince, blackberries, raspberries, 
other caneberries, and strawberries.  And, ready-to-use (RTU) formulations 
are being limited to cottonseed uses.  Existing stocks in the hands of 
retailers and users may be used as labeled until such stocks are exhausted.
