Grain protectants and fumigants: product update

摘要

Over the past three years, there have been a number of product releases and products awaiting registration in the grain storage protectants category. Most notably, the Spinosad product from Dow named 'Conserve' and the Deltametherin based 'K-ObioF from Bayer are two new grain protectants and therefore relevant only for growers in the eastern states. Being grain protectants, they need to be applied as grain is entering the storage and will not treat infested grain. Concerns from the Australian Pesticides and Veterinary Medicines Authority (APVMA) for both of these products revolve around the potential for breaches of Maximum Residue Levels (MRL) if the protectant was to be applied more than once to grain.
