The Australian Pesticides and Veterinary Medicines Authority (APVMA) has proposed to approve Bayer's Mateno Complete Herbicide, which contains aclonifen, an approved active constituent not previously included in a registered product.
Aclonifen has activity against many grass and broadleaf weeds, largely through pre-emergence activity. It can be applied pre- or post-emergence to a variety of crops. Major crops treated in Europe include wheat, potatoes, lentils, field peas, maize, sunflower and many minor vegetable and herb crops.
Mateno Complete Herbicide is an odourless, yellow coloured suspension concentrate. It contains a new combination of three active constituents, 400 g/L of aclonifen, 100 g/L pyroxasulfone and 66 g/L of diflufenican, as a suspension concentrate (SC) formulation.
The proposed product Mateno Complete Herbicide is intended for the pre-emergent or post-emergent control or suppression of various grass and broadleaf weeds in non-durum wheat and barley.
The APVMA has evaluated the chemistry of the active constituent aclonifen, and associated product Mateno Complete Herbicide, including the manufacturing process, quality control procedures, stability, batch analysis results and analytical methods, and found them to be acceptable. Based on a review of the chemistry and manufacturing details, the registration of Mateno Complete Herbicide is supported from a chemistry perspective.
The APVMA invites comment from 30 November 2021 to 28 December 2021 on whether approval of the active constituent and registration of the product should be granted.
