GM (Genetically modified) crops with herbicide tolerance have greatly driven the development of some herbicides in the past years. As some herbicide categories of ultra-high activity such as amide herbicides, sulfonylurea herbicides and imidazolone herbicides came out, the development of chemical weeding brought revolutionary change.
GM crops also impact the global herbicide market. Before herbicide-tolerant GM crops were developed, glyphosate only ranked the fifth in the global herbicide market, but now it is the biggest pesticide product which is well known in pesticide industry for many years. As more and more crops are resistant to glyphosate, competitive products of glyphosate such as glufosinate ammonium and dicamba come out.
In China, the six conventional herbicide products are glyphosate, paraquat, acetochlor, metolachlor, 2,4-D and atrazine. They have built some competitive relationship between the herbicide products of similar features, or similar supply and demand. Other competitive herbicide products also show their competitiveness mainly of similar features and their application fields.
In this report, the competitive herbicides had been analyzed exhaustively in the following aspects:
