Environmental and economic effects of management of weeds in genetically modified, herbicide tolerant (GMHT) sugar beet

The use of glyphosate in genetically modified herbicide tolerant beet would provide growers with a simpler and cheaper system. However, the ability of glyphosate to control a range of weeds at small or large growth stages also provides opportunities to manage weeds for environmental benefit. These include control of pernicious …
