Technical Abstract: Advances in biotechnology have led to development and commercialization of several herbicide-resistant crops (HRCs). Both transgenic (created through the stable integration of a foreign gene using molecular biological techniques) and nontransgenic (developed using traditional plant breeding techniques) HRCs are commercially available to farmers. HRCs as a weed management tool is a mere extension of utility of proven postemergence, previously non-selective, broad-spectrum herbicides. HRCs are readily accepted in North America and are slowly making inroads into parts of Asia, Africa, Australia, Europe, and South America. The farmers who have chosen HRCs must have seen some economic and weed control benefits, otherwise, the rapid increase in area planted to HRCs in recent years would not have occurred. There are benefits and risks associated with the use of HRCs as a weed management tool. Benefits of HRCs for weed management have outweighed their risks. HRCs should not be relied upon solely to exclude other weed control tactics and should be used within integrated weed management systems.
