ENVIRONMENTAL FATE
Pinoxaden's production may result in its release to the environment through various waste streams; its use as a herbicide will result in its direct release to the environment. If released to air, a vapor pressure of 3.5×10-9 mm Hg at 25 deg C indicates pinoxaden will exist solely in the particulate phase in the atmosphere. Particulate-phase pinoxaden will be removed from the atmosphere by wet or dry deposition. If released to soil, pinoxaden is expected to have moderate to high mobility based upon a Koc range of 852 to 121. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 9.1×10-12 atm-cu m/mole. Pinoxaden biodegrades rapidly with an aerobic half-life of 2 to 3 days in soil and an aerobic half-life of <1 day in water. If released into water, pinoxaden is expected to 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 estimated Henry's Law constant. An estimated BCF of 60 suggests the potential for bioconcentration in aquatic organisms is moderate. Pinoxaden hydrolysis half-lives are reported as 24.1, 25.3, 14.9 and 0.3 days at pH 4, 5, 7 and 9, respectively. Occupational exposure to pinoxaden may occur through inhalation and dermal contact with this compound at workplaces where pinoxaden is produced or used. (SRC)
Usage: Manufacturers: Syngenta. Pinoxaden is a selective post-emergence herbicide for the control of annual grass weeds in cereal crops. Pinoxaden belongs to the phenylpyrazole class of herbicides which acts by inhibiting the enzyme acetyl-CoA carboxylase (ACCase).
Application: For post emergence control of grass weeds in wheat (including durum) and barley. One application per crop season by agricultural workers using either open-cab ground boom equipment or via aerial application. Application rates of 0.036-0.062 lb active ingredient per acre.
