Residue Studies of Livestock Sprays Containing Sevin1

Carbaryl: A Literature Review

“…Carbaryl has been shown effective for the control of ticks , horn flies (JOHNSON and LONFORD 1960), and liee in livestock. The minimum effective time for carbaryl was 4 days for horn flies (RoBERTs et al 1960). It has been extensively used for the control of ectoparasites on poultry (ZIV et al 1977) including its use to control chicken mites and lice, as weIl as bedbugs, northern fowl mites, and fleas (Union Carbide Corporation).…”

“…Carbaryl has shown promise for control of livestock insects due to lack of persistence in body tissues and the environment (ROBERTS et al 1960, CLABORN et al 1963, }OHNSON et al 1963. CLABORN et al (1963) studied residue levels in fat, brain, liver, kidney, he art, and muscle of several animal species.…”

“…Dairy cattle sprayed 4 times at 4-day intervals with a 0.5% carbaryl suspension were studied for milk and fat residues (ROBERTS et al 1960). SampIes were collected at 5 hr and 1, 2, and 4 days after each spraying.…”

Carbaryl-14C metabolism in a lactating cow

“…Direct dermal applications of carbaryl sprays and dusts to cattle have been shown by several workers to result in little, if any, residues in meat or milk from the treated animals (1,3,5,9). In each of the aforementioned studies, a colorimetric method using p-n itrobenzenediazonium fluoborate as a chromogenic reagent was used to detect carbaryl and its metabolites.…”
