Now if tests were that thorough, there would be every possible weed occurring in all 50 states listed as either controlled or not controlled. As is, I have to do a lot of field trials. The labels are extremely incomplete in that area. There would also be testing to see if a desired species of turf is tolerant or intolerant under all possible growing conditions. A colleague and I got results from a particular herbicide, in combination with another herbicide not explicable by the product labeling. A turf grass that should have been killed, survived while laying waste to some otherwise bulletproof weeds. In addition to making people happy, another sore subject with me is CYA for the sake of CYA. Anyone that thinks and acts in those terms or otherwise plays that game is kept far away from me. I think that is what has gone wrong with Western civilization. Says a lot about the integrity of men. Meaning that product manufacturers need to worry about someone doing something stupid and not taking responsibility for their mistake. Its not a manufacturer's fault that people do not pay attention to the weather or do a "one second pour" when measuring surfactant. Also is not a manufacturer's fault if their product is going to be applied by someone running across a lawn swinging a gun with a sprinkler nozzle flowing a guestimated gallonage. It certainly is not their fault if a product is applied to a starved and dried out lawn causing either a control failure or turf damage.
