(c)As of 1999 the most prevalent GM trait was glyphosate-resistance (pesticide). This herbicide used on grain and grass crops were highly toxic and not effective against narrow-leaved weeds. Thus, developing crops that could withstand spraying with glyphosate would both reduce environmental and health risks. Tobacco plants have been engineered to be resistant to the herbicide bromoxynil. Crops have been commercialized that are resistant to the herbicide glufosinate also. The main objective of this herbicide resistant GM crops is that it reduces the accumulation of herbicides in the food articles for health safety.
