US EPA denies emergency propazine use
The US EPA has turned down a request by the Texas Department of Agriculture (TDA) for an emergency exemption to allow the use of Albaugh's herbicide, Milo-Pro (propazine), on up to 3 million acres (1.2 million ha) of cotton. The TDA sought the exemption for the control of glyphosate-resistant Palmer amaranth (Amaranthus palmeri), citing a lack of suitable alternatives and the potential for significant economic losses (Agrow No 691, p 16). The EPA acknowledges that emergency criteria have been met but it has denied the request due to its human health risk assessment. Currently registered uses of propazine already show unacceptable risk levels, so it is not possible to add another use to cotton, the Agency notes. Moreover, it is developing a cumulative risk assessment for triazine herbicides that would be required prior to making a safety finding for the proposed use.
