Ok, couple of bad lawns that have these three hard to kill weeds - violets, creeping charlie, and clover. Called Lesco and they say that there is no problem w using momentum to kill these, but it might take a follow-up spray 2-3 wks later to do the job. HOWEVER, anyone I have talked to in here, anyone I have talked to in town, and any research on here says that these three are very tough to kill and that it takes OTHER chemicals to do it. IN FACT, on two lawns, both homeowners contacted me to kill their violets and creeping charlie and clover and they told me that the other local guy that has been treating them for years said he cannot kill any of these three. I told them that we could and it is just a matter of finding the right chemical and or mix of chemicals and a matter of timing the applications. (i hope) ALSO, while talking to the other local guy, when we were talking $, he asked us what was in our tank and we replied $100 worth of chemicals and he flipped, insinuating that we were investing way too much. He asked where we got the chemicals and we told him Lesco and he had never heard of them. wtf? I think he buys just from the farmers elevator here in town. His broadleaf spray is a bright yellow, but I don't know what he is actually using. Does anyone have an opinion on this and if they have found that Momentum takes care of the above? Please help if you can.
