Sprays of 0.5 per cent (weight by volume) CO-RAL wettaible powder (WP) in water applied to the entire body of the unweaned calves on September 12, 1958, reduced warble infestation by 99.5 per cent and gave significantly better control (P < 0.01) than similar treatments with CO-RAL emulsifiable concentrate (EC) or WP on October 30, 1958. Topline spraying in October with 0.75 per cent CO-RAL EC was as effective as similar over-all sprays applied at the same time or 0.5 per cent CO-RAL WP sprayed over-all 6 weeks earlier. There was no significant difference between the efficacies of wettable powder and emulsifiable concentrate of CO-RAL.A recurrence of shipping fever was noticed in the herd sprayed soon after weaning and shipping. This condition was not observed in calves sprayed before weaning. Clinically none of the treated calves showed any cholinergic signs of organophosphate poisoning.
