Herbicide Tolerant Canola

Herbicide Tolerant Canola (HT Canola) is canola (rapeseed) that has been genetically engineered to survive being sprayed with a specific herbicide. The first generation of HT crops included Roundup Ready Canola, made by Monsanto to survive spraying by its best selling herbicide Roundup (glyphosate) and Glufosinate Tolerant Canola, which survives being sprayed with the herbicide glufosinate. Roundup Ready Crops in particular were widely adopted, resulting in the evolution of glyphosate resistant weeds.
