Abstract
She insecticide GC-65061 (phosphoric acid, dimethyl ~-methylthiophenyl ester) is a potential acaricide and insecticide for use on cotton. A sensitive and reasonably specific method for determining residues of the compound in cottonseed was required to establish the levels that might be found following its use. A gas chromatographic procedure was developed, utilizing a phosphorussensitive detector, that provided the degree of minimum detectability (0.05 ppm) and specificity required for the study.
