After several months of uncertainty, Monsanto BioAg will continue to offer Met 52 bioinsecticide. However, as new sources of inputs are being pursued, the product will not be available between February and October 2016.
This affects both the EC and Granular formulations.
Met 52 (which contains the beneficial fungus Metarhizium anisopliae) is one of three fungal-based bio-insecticides we have registered in Canada for greenhouse pests such as thrips and whitefly.
During this gap period, growers using Met 52 in their IPM programs may want to switch to products containing the fungus Beauveria bassiana (e.g. BotaniGard 22WP, BioCeres WP). Beauveria also has activity against thrips and whitefly. For more details on best use of Beauveria-based products, see this page on the GreehouseIPM.org website.
