I respect the law and those who abide by it. I do not have a pesticide certification and therefore will not violate. I do have a client in my neighborhood who evidently picked up a bag from Fleet Farm or something that said 'Crabgrass Killer and Fertilizer', then spread it around his lawn. Before it is even washed in he is on a fishing trip and asks me to keep his landscape alive. While I am at it - would I throw down some more grass seed!?!? I suspect his store bought Pre-M is not going to allow anything to grow for most of our short summer, so I have been reading labels trying to find 'Siduron' in order to let him know to pick up a particular product next year. No Luck. Is Siduron available only to liscenced personal? or can my client stop crabgrass next spring with an 'off the shelf' product? and still sow KBG/Fescue with hope of success? Of course I will help him seed more this fall. Thanks for advice and is the product what it claims to be? .rick.
