Chlordane and DDT are about equal in efficiency against the red and 
yellow goat lice. In a limited number of tests a 0.2-percent concentra- 
tion of chlordane in dip form with either wettable powder or emulsion gave 
complete control which was maintained for at least k months. — U. S. Bur.

Chlordane emulsion was better than chlordane wettable powder, which 
was better than DDT wettable powder. The LD-50 of chlordane in emulsion 
form was 0.0^+3 percent. The sprays were applied to Shetland ponies by 
means of an electric hand sprayer. — Batte and Gaines (28) .

The addition of 0.9 ounce of chlordane per gallon of light-medium 
emulsion oil which was applied as a 1.67-percent water emulsion did not 
enhance the toxicity of the oil to 1st, 2nd, and 3rd-instar larvae or to 
pupae. — Plummer and Shaw ( 3 , 68 ). 
Chlordane in Velsicol AE-60 or kerosene exhibited low toxicity. —

When applied as dusts containing 1 percent of the toxicant, chlor- 
dane was less toxic (52.6 percent mortality) than gamma-BHC (97.8) or 
aerosol grade DDT (85.6) to adults. — Sun et al. ( ^50 ).
