Bifenazate TC

English Name: BIFENAZATE
Chemical Name: Isopropyl 3-(4-methoxybiphenyl-3-yl)carbazate
Other Names: NC-1111; CRAMITE; D2341; FLORAMITE
Molecular Formula: C₁₇H₂₀N₂O₃
Molecular Weight: 300.35
Physicochemical Properties:
Bifenazate is a biphenyl hydrazine acaricide. Its pure form appears as a white crystalline solid; solubility (20°C): 2.1 mg/L in water; in organic solvents (g/L): 24.7 in toluene, 102 in ethyl acetate, 44.7 in methanol, 95.6 in acetonitrile; partition coefficient (n-octanol/water): Log Pow = 3.5.

Action Characteristics and Insecticidal Spectrum:
Bifenazate is a novel selective acaricide for foliar spraying. Its mechanism of action involves a unique effect on the GABA receptors in the central nervous system transmission of mites. It is effective against all life stages of mites, exhibiting ovicidal activity and knockdown activity against adult mites (48-72 hours), with a long duration of efficacy. The effective period is about 14 days, and it is safe for crops at recommended dosage rates. It poses low risk to parasitic wasps, predatory mites, and lacewings.
Used on apples and grapes to control European red mites, two-spotted spider mites, and McDaniel mites, as well as two-spotted spider mites and Lewis mites on ornamental plants.
Formulations:
24%, 50% bifenazate suspension concentrate, 2.5% bifenazate emulsion in water
