US EPA to approve D7 bioherbicide

The US EPA proposes to approve US company Northwest Agricultural Products' (Pasco, Washington) bioherbicide, D7 (Pseudomonas fluorescens strain D7), for the suppression of downy brome (Bromus tectorum), Japanese brome (B japonica), medusahead (Taeniatherum caput-medusae) and jointed goatgrass (Aegilops cylindrica) in cereals, alfalfa, rangeland, turf and grasses grown for seed. It would be used as a seed treatment or as a ground or aerial spray. The product should be applied before weed seeds germinate in the spring or autumn and prior to expected rainfall. It can be used up to four times a year at a maximum annual rate of 8 g/acre. The EPA granted an experimental use permit to allow applications of the bioherbicide in the states of Oregon and Washington between March 1st 2012 and March 1st 2015. It notified receipt of an approval application last year (Agrow No 676, p 15).  The proposed approval is subject to public comment until August 27th.
