DECATUR, Ill. (DTN) -- My family is great for sayings. One of my grandmother's favorites is: "The difference between a flower and a weed is judgment."
My grandmother will be 103 years wise this August and her old adage kept whispering to me this spring as I spotted roadside daffodils lining farm fields thickly carpeted with purple deadnettle, henbit and chickweed.
The fields and gardens of my youth were classrooms for learning the important differences between pest species. Unfortunately, we let a lot of those lessons fall by the wayside as herbicide-resistant technologies came on the scene.
There's no question ...
