Bifenazate, Hydrazine carboxylic acid, 2-(4-methoxy-[1,1'-biphenyl]-3-yl)methylethyl ester, belongs to the carbazate chemical class. Its water solubility is 3.8 mg/L. With a KOW of 2512 bifenazate is not likely to bioaccumulate. Its vapor pressure is low at 1x10-7 mmHg so volatilization will not contribute significantly to its dissipation. 

Bifenazate's mode of action is unknown at present and is under investigation. 

Bifenazate is practically non toxic to birds and mammals on an acute basis but can cause chronic toxicity. It is moderately toxic to honeybees with an LD50 of 7.8 ug/Bee. It is highly toxic to all aquatic organisms tested except Mysid shrimp for which it is very highly toxic.

Acramite 50WS contains the active ingredient bifenazate (hydrazine carboxylic acid, 2-(4-methoxy-[1,1,-biphenyl]-3-yl) 1-methylethyl ester) and is labeled "for agricultural use only" to control mites on a variety of fruit crops, such as apples, strawberries, grapes and plums, as well as hops and cotton. Bifenazate is currently registered in the State for use on ornamental plants. The use of bifenazate on food crops represents a major change in labeled use pattern in New York State.
