Cattle from Kerrville and College Station, Texas, and Highmore, South Dakota, were treated orally, intramuscularly, or dermally with dimethoate. Oral and intramuscular dosages ranged from 5 to 20 mg./kg. and the strength of dermal sprays from 0.25 to 1%. Cattle grub control ranged from 10% to 96%, depending on the dosage. Those animals treated at the higher dosages were poisoned by the insecticide. There does not appear to be an adequate margin between the dosage that is effective against first-instar Hypoderma larvae and the dosage toxic to cattle.
