ENVIRONMENTAL FATE
Fosetyl-aluminum's production may result in its release to the environment through various waste streams; its use as a fungicide will result in its direct release to the environment. If released to air, a vapor pressure of <7.510-10 mm Hg at 25 deg C indicates fosetyl-aluminum will exist solely in the particulate phase in the ambient atmosphere. Particulate-phase fosetyl-aluminum will be removed from the atmosphere by wet or dry deposition. If released to soil, fosetyl-aluminum is expected to have very high to moderate mobility based upon Koc values ranging from 20 to 311. Volatilization from moist soil surfaces is not expected based upon an estimated Henry's Law constant of 3.210-15 atm-cu m/mole. Volatilization of fosetyl-aluminum from dry soil surfaces is not expected based upon its vapor pressure. Half-lives ranging from <1 to <1.8 hours have been reported for fosetyl-aluminum in soil. If released into water, fosetyl-aluminum is not expected to adsorb to suspended solids and sediment based upon its Koc values. Volatilization from water surfaces is not expected based upon this compound's estimated Henry's Law constant. An estimated BCF of 3.2 suggests the potential for bioconcentration in aquatic organisms is low. A rate constant of 0.122 d-1 had been reported for the hydrolysis of fosetyl-aluminum; this corresponds to a half-life of 5.7 days. Occupational exposure to fosetyl-aluminum may occur through inhalation and dermal contact with this compound at workplaces where fosetyl-aluminum is produced or used. (SRC)
Usage: Fungicidal activity of aluminium salt reported by D. Horrire et al. (Phytiatr.-Phytopharm., 1977, 26, 3). Fosetyl-aluminium was introduced by Rhône-Poulenc Agrochimie (now Bayer CropScience); first registered in 1977 in France. Manufacturers: Bayer CropScience; Sannong.
Application: Acts by inhibiting germination of spores or by blocking development of mycelium and sporulation. Systemic fungicide, rapidly absorbed through the plant leaves or roots, with translocation both acropetally and basipetally. Used to control of diseases caused by e.g. Phytophthora, Pythium, Plasmopara, Bremia spp., etc. on a variety of crops including vines, fruit (citrus, pineapples, avocados, stone fruit and pome fruit), berries, vegetables, hops, ornamentals and turf. Application rates range from 1-7 kg/ha in citrus, 2 kg/ha in tree nuts, up to 3.6 kg/ha in pome fruit, 2 kg/ha in grapes and 2.4-4.5 kg/ha in cucumber. Also useful activity against several bacterial plant pathogens.
