Pyroxsulam and Cloquintocet-Mexyl in the Product Crusader Herbicide

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has before it an application from Dow AgroSciences Australia Limited to extend the use of the product, Crusader Herbicide, containing 30 g/L pyroxsulam and 90 g/L cloquintocet-mexyl, to triticale and rye for the control and suppression of various weeds. The application also includes a reduction in the current grazing withholding period for wheat from 6 weeks to 4 weeks. The proposed use requires the establishment of permanent MRLs for pyroxsulam in triticale and rye grain, triticale and rye forage, and triticale and rye straw and fodder. A change in the current MRL for wheat forage is also required. The current MRLs for cloquintocet-mexyl remain appropriate for the proposed use pattern; therefore, no further consideration of the proposed use of cloquintocet-mexyl is required.
