ENVIRONMENTAL FATE

Dimethazone's production may result in its release to the environment through various waste streams; it's use as a herbicide will result in its direct release to the environment. If released to air, a vapor pressure of 1.4×10-4 mm Hg at 25 deg C indicates dimethazone will exist solely as a vapor in the atmosphere. Vapor-phase dimethazone 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 5.8 hours. Aqueous solutions of dimethazone have a half-life of greater than 30 days when exposed to sunlight. If released to soil, dimethazone is expected to have moderate mobility based upon a Koc values ranging from 60-573. Volatilization from moist soil surfaces is not expected to be an important fate process based upon a Henry's Law constant of 4.13×10-8 atm-cu m/mole. Dimethazone is not expected to volatilize from dry soil surfaces based upon its vapor pressure. After 84 days 59% of 14C radiolabeled dimethazone extracted from the soil remained unchanged, indicating that dimethazone is degraded slowly. If released into water, dimethazone may adsorb to suspended solids and sediment based upon the Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's Henry's Law constant. An estimated BCF of 17 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions.   

Usage: Herbicide introduced by FMC Corp. Patents: US 4405357. Manufacturers: FMC; Sannong. Inhibits carotenoid biosynthesis; target enzyme not known.

Application: Selective herbicide, absorbed by the roots and shoots and translocated upward. Susceptible species emerge but are devoid of pigmentation. Control of broad-leaved and grass weeds in soya beans, peas, maize, oilseed rape, sugar cane, cassava, pumpkins, and tobacco. Applied pre-emergence or pre-plant incorporated. Foliar contact or vapours may cause visual symptoms of chlorosis to nearby sensitive plants.
