In 2011, a new 2,4-D product namely 2,4-D choline has been under industrial production by Dow AgroSciences. Owing to its advantages of high efficiency of weeding, low pollution to the environment, wide application areas can also be applied to GM crops, and production of 2,4-D choline will create more development space for the whole 2,4-D industry worldwide. Meanwhile, the promotion of this new product is largely affected by many factors, such as its price higher than that of other 2,4-D products, planting areas of GM crops affected by the attitude of local governments, etc.
