I really appreciate the help. We do not have Lesco around here but I will check out the website mentioned. I used the image exactly as recommended and practiced with my backpack and sprayer to get it calibrated correctly. My concern on one yard is once the weeds are gone the guy won't have anything else. Explained too that the Image was going to kill the winter rye as well but that it would die in the summer anyway. I actually suggested waiting to next kill everything and start over. The other yard is sod and very nice. I don't want to mess it up. He has only a couple of weeds that I actually took to another guy to help identify. The dominant weed was nutsedge based on the experienced guy but in my book it doesn't match up exactly. Based on the book is was closer to chickweed but it has little yellow flowers. Whatever it is I have found it in every yard I have worked in this year landscaping, mowing, etc. just in varying amounts. Now that I am spraying I better learn quickly. Applying as required is the easy part but this identifying and knowing what to use without destroying someones yards is hard. Thanks again.
