Dow gains 2nd patent for Enlist crops

Dow AgroSciences has received a second patent covering genetically modified crops with tolerance to broadleaf herbicides such as 2,4-D. US patent 8,283,522 covers an aryloxyalkanoate dioxygenase gene and enzyme conferring tolerance to 2,4-D and pyridyloxyacetate herbicides in dicotyledonous plants such as soybeans and cotton. It also applies to use of the trait in stacks with other herbicide tolerance traits. The company had previously been granted patent 7,838,733 covering tolerance to 2,4-D in maize and other monocotyledonous plants. Both traits form part of Dow’s Enlist weed control system.
