New way to determine if that weed is resistant to herbicides.
The Purdue Plant and Pest Diagnostic Laboratory has developed a Molecular Assay test to determine herbicide resistance. In the past the process to determine if a weed had developed resistance required gathering seed, growing these seeds in a greenhouse and then applying that herbicide. Now you can simply gather some of the existing weeds and test for resistance using the molecular assay. This is a much quicker and more economic way to test for resistance than was available in the past.
