The Development of Herbicide-resistant Crops

The intensive use of glyphosate in glyphosate-resistant crops across wide areas has resulted in extremely high selection pressure for the evolution of glyphosate-resistant weeds. Consequently, growers now have glyphosate-resistant and tolerant weed populations and can no longer rely only on glyphosate for weed management. This paper discusses the development of non -glyphosate resistant crops, such as glufosinate, imidazolinone, sulfonylurea, bromoxynil, cyclohexanedione, HPPD and PPO -resistant crops. Fortunately, companies are developing new herbicide -resistant crop technologies to combine with glyphosate resistance and expand the utility of existing herbicides, a molecular stack combines the herbicide -resistant genes in the same genetic construction and thus makes it easier for work with the multiple traits, and development of multiple-herbicide-resistant crops.
