Sevin® (I-naphthyl N-methylcarbamate) applied as a dry powder to the backs of 48 dairy cows at 10 g. of 50% wettable per cow was not detectable in milk 2, 10, or 16 days after treatment. When 1% Sevin was sponged onto the backs of 10 dairy cows at 1 quart per cow, Sevin and 1-naphthol residues were present in milk for the first 24 hours after treatment. However, 0.5% Sevin sprayed on the backs of five cows was not detectable in milk, except in one instance, within 14 days after treatment. The lower limit of sensitivity of the method was 0.025 p.p.m. corresponding to 2.5 μg. of Sevin per 100 g. of milk. |
