Dow AgroSciences will market penoxsulam under the trade name, LOCKUP?EUR??,,????'?????????????? specialty herbicide. LockUp will be available to distributors as a formulated product alone and in combination with other selective herbicides on fertilizers or straight granules.

Penoxsulam is the first ALS inhibitor formulated on a granule. This mode of action inhibits plant enzyme acetolactate synthase (ALS), which is essential for the synthesis of amino acids. Inhibition of amino acid production subsequently inhibits cell division and causes death in susceptible plants. For turf managers in the South, LockUp will provide superior control of dollar weed with an excellent environmental profile compared with atrazine-containing products.?EUR??,,????'?????<
