Verdesian to debut D7 bioherbicide in US
The US crop protection and nutrition company, Verdesian Life Sciences (Cary, North Carolina), is to introduce the bacterial bioherbicide, D7 (Pseudomonas fluorescens strain D7), for the 2015 season. It is for the suppression of downy brome (Bromus tectorum) in cereals, grass grown for seed, alfalfa (lucerne), rangeland and non-crop areas. For wheat growers using acetolactate synthase (ALS) inhibitors against the weed, D7 will offer a second mode of action and help protect against ALS resistance development, the company points out. D7 will be recommended for use in-furrow, via aerial application or as a seed treatment. The US EPA granted a tolerance exemption for D7 to Northwest Agricultural Products (Pasco, Washington) last month following approval in August.
