Abstract
A single application of aerosols containing 5% of DDT gave satisfactory control of horn flies, Siphona irritans, on range cattle for 2 weeks. Cage tests indicated the aerosols did not remain highly toxic after 4 days; thus, the longer protection in pastures may be due to destruction of the existing fly population. Sprays containing DDT gave equally satisfactory control when they contained at least 0.2% DDT and were applied with a power sprayer or when they contained not less than 2.5% DDT and were applied with a hand sprayer. Two satisfactory formulas were: (1) DDT 100 gms., benzene 140 ml., kerosene 140 ml., and Triton NE 8 gms.; (2) DDT 100 gms., benzene 140 ml., dibutyl phthalate 140 ml., and Triton NE 12 gms. plus, in both cases, water to make 1 liter.This publication has 0 references indexed in Scilit:
