Australia to approve Bayer's Method 240 SL Herbicide

The Australian Pesticides and Veterinary Medicines Authority (APVMA) is considering an application for registration of Bayer Crop Science Pty Ltd’s new product, Method 240 SL Herbicide, a soluble concentrate formulation containing 240 g/L of the approved active constituent aminocyclopyrachlor.

Aminocyclopyrachlor was approved as an active constituent in 2014 and the product Method 240 SL Herbicide is the first proposed product to contain aminocyclopyrachlor.

This proposed product, Method 240 SL Herbicide, is intended for use the control of woody weeds and other invasive weed species in native conservation areas, pastoral grazing land, industrial sites such as railways, roadways and utility rights-of-way.

The proposed product, Method 240 SL Herbicide, has a disruptor of plant cell growth mode of action and is a member of the herbicide mode of action group 4 (pyrimidine carboxylic acids).

The APVMA has evaluated the chemistry of the active constituent aminocyclopyrachlor and associated product Method 240 SL Herbicide, including the identification, physicochemical properties, 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 Method 240 SL Herbicide is supported from a chemistry perspective.
