Diphenylamine; Technical Amendment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; technical amendment.

-----------------------------------------------------------------------

SUMMARY: EPA is issuing a technical amendment to a regulation on 
diphenylamine to change its designation from a ``fungicide'' to a 
``plant regulator.'' EPA is making this technical amendment to better 
characterize the chemical.

FOR FURTHER INFORMATION CONTACT: By mail: James A. Tompkins, Fungicide/
Herbicide Branch (7505C), Registration Division, Office of Pesticide 
Programs, Environmental Protection Agency, 401 M St., SW., Washington, 
DC 20460. Office location and telephone number: Rm. 239, CM #2, 1921 
Jefferson Davis Hwy., Arlington, VA, (703)-305-6250; e-mail: 
[e-mail].

SUPPLEMENTARY INFORMATION: Diphenylamine is currently registered for 
use on apples to prevent the appearance of the skin discoloration known 
as ``storage scald.'' Storage scald is an abiotic disorder not caused 
by fungus, bacterium, or living agent. The most widely accepted theory 
is that a substance known as alpha-farnescene is given off by the apple 
which when combined with oxygen leads to the formation of free radicals 
resulting in the destruction of cell substance compartmentalization and 
death of the skin cells. Diphenylamine applied to the skin of the apple 
acts as an antioxidant to prevent the combination of alpha-farnescene 
with oxygen. The term ``plant regulator'' is a better descriptive term 
than ``fungicide'' to describe the use of diphenylamine on apples to 
prevent the appearance of storage scald.
    This document contains a technical amendment only and does not 
require notice and comment, 5 U.S.C. 553.
