Prothioconazole and Tebuconazole in the Product Prosaro 420 SC Foliar Fungicide

The Australian Pesticides and Veterinary Medicines Authority (APVMA) has before it an application from Bayer CropScience Pty Ltd to vary the registration of the product, Prosaro 420 SC Foliar Fungicide, containing 210 g/L prothioconazole and 210 g/L tebuconazole, to include the control of Sclerotinia stem rot in canola. The proposed use does not require modification of existing MRLs, however, the proposed use involves application at a later growth stage and hence the potential for higher residues in canola seed.
