Crabgrass. That's what buggin me. Just when you get all the broadleaf weeds under control, the annual ones show up. Not as easy to control as broadleaf weeds, but thanks to new chemistry's, we have products available to use. Prior to just a few years ago, the only way to contol annual grasses was to apply a pre emergent compound, usually with fertilizer, to prevent germination. Today, there is a product that you apply post emergently that takes out the crabgrass just as you would with broadleafs. The active ingredient in this product is called Quincloroc. It is available to consumers now and that is a good thing if you want to clean up any breakthrough from your pre emergent application in the spring. Get them now before the seeds appear other wise the cycle will continue for next year.
I applied this product to the tees and approaches last week and happy to report that the crabgrass is yellowing and going back to wherever it came from. The pictures show the beginning of the end of these pesky invaders. There is some crabgrass on the perimeters of a few fairways but I will document the locations and plan a course of action for next year.
