Isoxaflutole in the Product Balance 750 WG Herbicide

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has before it an application from Bayer CropScience to vary the label of Balance 750 WG Herbicide, containing 750 g/kg isoxaflutole. The product is proposed for use in fallow situations.

A change to the residue definition is proposed as the benzoic acid metabolite (2-methylsulfonyl-4- trifluoromethylbenzoic acid) is a common metabolite with pyrasulfotole, and is not currently included in the residue definition for pyrasulfotole. This change in the residue definition requires a change to the MRL for chickpeas.

New residue data for chickpea forage indicates the need for change to the MRL for isoxaflutole in Edible offal (mammalian). The proposed use also requires establishment of permanent MRLs for isoxaflutole in cereals.
