[Effectiveness, tolerance, and residue formation of trichlorbon 6%-"new" in controlling hypodermyiasis in cattle in the Mongolian People's Republic].
Field trials in more than 3,000 head of cattle proved the efficacy and compatibility of the insecticide Trichlorphon 6%-"neu"--manufactured by the chemical works in Bitterfeld, German Democratic Republic, on the basis of domestic active ingredients--to be equal to the insecticides used until now. The inhibition of the activity of cholinesterase was moderate but longer lasting than with other preparations. The advantages of Trichlorphon 6%-"neu" are the substitution of imported substances by domestic products, prolonged efficacy, and--by a new formulation--its application at temperatures below zero.
