Kelthane Residues on Gravenstein Apples and Pomace—Application and Removal

University of California¹, Davis 95616

Abstract

KELTHANE (dicofol; 1,1-bis-(p-chloro-phenyl)-2,2,2-trichloroethanol) has been recommended for usage on apples in California for the control of the European Red Mite, Two Spotted Mite, McDaniel Mite and Brown Mite.

If Kelthane is applied to apples for mite control, it is possible to have residues of 5 ppm or higher at the time of harvest. These residues will carry on into the apple by products such as peel, cores and pomace which are potential sources of animal feed making them unusable and unmarketable.

Cassidy, Kocvara and Murphy (1968) studied the fate of Acarol (isopropyl 4,4' dibromobenzilate) residues on apples. The decrease of these residues with time was primarily a function of apple growth and there was no evidence of significant penetration of the pesticide into the meat.

The problems of pesticide accumulation in adipose tissue of beef cattle fed contaminated apple processing wastes and investigations for the alleviation of these problems has been published (Bovard et al., 1961; Rumsey et al., 1969; Wilson et al., 1970).
