Fentin acetate's production and former use as an agricultural fungicide and as a biocide in marine antifouling paints resulted in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 4.8×10-7 mm Hg at 25 deg C indicates Fentin Acetate will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase Fentin Acetate will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 2.7 days. Particulate-phase Fentin Acetate will be removed from the atmosphere by wet and dry deposition. If released to soil, Fentin Acetate is expected to have low mobility since triphenyltins are strongly adsorbed to soil. In moist soil and water, Fentin Acetate will dissociate to form triphenyltin oxides, hydroxides, carbonates, or hydrated cations; these species are not expected volatilize from moist soil orwater surfaces. If released into water, Fentin Acetate is expected to adsorb to suspended solids and sediment. Fentin Acetate undergo biodegradation in the environment. Fentin Acetate degraded in normal, fertile, agricultural field at 11-16 deg C in <6 wks under aerobic conditions and 6-18 weeks under anaerobic conditions. A BCF of 800 for rainbow trout suggests bioconcentration in aquatic organisms is high. Occupational exposure to Fentin Acetate may occur through inhalation and dermal contact with this compound at workplaces wheretriphenyltin acetate is produced or used. (SRC)

Usage: Fungicidal properties of organotin compounds investigated by G. J. M. van der Kerk & J. G. A. Luijten (J. Appl. Chem., 1954, 4, 314; 1956, 6, 56) and reviewed by H. Bock (Residue Rev., 1981, 79, 1). Fentin acetate was introduced by Hoechst AG (now Bayer CropScience) and fentin hydroxide by N.V. Philips-Duphar (now Crompton Corp.), both in 1959/1960.

Application: Multi-site inhibitor, preventing spore germination, and inhibiting metabolism of the fungal organism, in particular respiration. Non-systemic fungicide with mainly protective action, but also some curative action. Also acts as an algicide and molluscicide. Used to control of early and late blights of potatoes (at 200-300 g/ha), leaf spot diseases of sugar beet (at 200-300 g/ha), anthracnose of beans (at 200 g/ha). Phytotoxicity Vines, ornamentals, some fruits, and glasshouse crops may be injured.
