Aspects of weed resistance to auxinic herbicides
Synthetic auxins have been widely used for selective control of broadleaf weeds since the mid-1940s. After more than 70 years using synthetic auxin herbicides, there are 41 different resistant species reported. Weed resistance to auxin herbicides is poorly understood and in most reported cases, no studies have been done to investigate the mechanistic changes that occur in resistant populations. The mechanisms of herbicide resistance in weeds are classified as 1) target-site when mutations reduce the interaction of the herbicide molecule to its binding site and/or changes of gene expression of ...
