Parathion-Residue Studies on Acerola

Abstract

This paper reports the results obtained in studies carried out with spray deposits left by the insecticide Parathion on West Indian cherries. Although data are not final, it seems that Parathion applied at the rate of 1.5 pounds per 100 gallons of water per acre to West Indian cherries leaves a residue which is below the limit established for fruits by the Food and Drug Administration of the U. S. Department of Health, Education, and Welfare. The results thus far obtained indicate that Parathion is rapidly degraded under the conditions of these experiments. It seems too early to make any final recommendations. More experiments have to be performed, especially during other seasons of the year, so that results can be compared and critically evaluated.
