ACTIVITY - Antiparasitic; Acaricide. The efficacy of N-(2-(5-chloro-2H-benzotriazol-2-yl)-1-cyano-1-methylethyl)-4-trifluoromethoxybenzamide (Ib) against Haemonchus contortus was tested as follows: the Haemonchus contortus was treated with comound (Ib) 0.01 part per million for 4 days. After 4 days percentage motility was measured. The compound (Ib) showed percentage motility was 90%.    MECHANISM OF ACTION - None given.    ADMINISTRATION - Dosage is 0.5 mg to 5 g; or 1-500 mg; or 0.1-100 mg/kg. The mode of administration is oral, injection, topical, or dermal.
