Terbuthylazine in the Product Terbyne 750 WG Herbicide

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has before it an application from Sipcam Pacific Australia Pty Ltd to vary the registration of the product, Terbyne 750 WG Herbicide, containing 750 g/kg terbuthylazine, to extend the directions for use to include pre-sowing and pre and postemergence use in sorghum for the control and suppression of various broadleaf and grass weeds. The proposed extensions of use require the establishment of permanent MRLs for terbuthylazine in sorghum.
