Since 1995, ITB has been experimenting on GMO sugar beet tolerant to a non selective herbicide to assess its performance and impact on the management of beet fields. The impact is evaluated on both the development of weed beet populations and the management of several crops tolerant to the same herbicide. Weed beet have been present in beet fields since the late 1960s and are currently found on 4.5 percent of beet area. The origin of the weed populations is well-known and its development is under control. Growing genetically modified (GM) beet tolerant to a non selective herbicide can mean that the tolerant genes are passed on to these weed populations. ITB is evaluating the consequences that this gene transmission can have on the development of weed populations in the beet crop and other crops in the rotation (tolerant or not) and giving advice on how to manage them. Apart from weed beet, the evaluation of the introduction of GM beet includes the management of beet volunteers (trailing) in other crops in the rotation (tolerant or not to the same herbicide) and the management of other crop volunteers tolerant to the same herbicide (rape) in beet.
