Purdue University's weed science professor, Bryan Young, has highlighted the growing issue of herbicide resistance, particularly in waterhemp, among farmers. This problem has led to increased weed control difficulties, prompting some growers to consider alternative strategies. The use of over-the-top dicamba is no longer an effective solution in some areas due to resistance. Young suggests that farmers may need to experiment with different herbicide combinations to effectively control weeds, especially with the current challenges in effectively using dicamba and certain other herbicides.
