New Systemic Insecticide Shows High Control Of Cattle Grubs
USDA entomologists report a new organophosphorus insecticide provides 94-100 percent control when taken orally and 99-100 percent as a spray in tests on Hereford yearlings. Trials at Corvallis during 1957-58 used dosages of 20-25 mg per kg for strong results, with spray applications delivering near total control.
