Marrone seeks US OK for second bioherbicide
The US biopesticide company, Marrone Bio Innovations (MBI – Davis, California), has applied for US approval of its second bioherbicide, MBI-011. Based on the pepper plant extract, samentine, MBI-011 is a post-emergence burn-down herbicide that can also be used as a crop desiccant, the company points out. It will be recommended for the control of annual and perennial grass and broadleaf weeds in agricultural, non-crop and home garden markets. MBI-011 has contact activity and no post-application planting restrictions are expected, MBI notes. The company received US approval for its first bioherbicide, MBI-005 (non viable Streptomyces acidiscabies strain RL-110 17%), for use on a range of food crops, turf and ornamentals in May 2012 ( Agrow No 640, p 20). MBI unveiled details of a further bioherbicide, MBI-010, last year ( Agrow No 653, p 27).
