Abstract

One of the main methods for controlling the Trichostrongylidae infection in sheep is to reduce the number of their infective stages. It is clear that success was obtain ed by the app < /strong>lication of insecticides, Asuntol, Bercotox, Seven, Neguvon and Malath ion which gave 100% lethal effect to them at a concentration of, 0.6 mg/gm faeces, 5 mg/gm faeces, 5 mg/gm faeces, 4 mg/gm faeces and 4 mg/gm faeces respectively. The anthelmintic Thiabenzole gave 100% effciency at low concentration of 0.4 mg/ga faeces. Other chemicals p < /strong>roved to be less efficient.
