We have had a lot of rain here this year. Weeds have been extremely persistent because of it. Especially ones that love wet conditions(Nutgrass, various sedges and Virginia Buttonweed) We have rotated products this year. R-2 we used Certainty, R-3 we used Sedgehammer and now R-4 we have been using Basagran T/O. I have never used Basagran before this season and I have to say, I have been impressed. It has pretty much wiped out all sedges we have sprayed. The label says it will not control Purple nutsedge but we see very little of that. Yellow Nutsedge, Globe sedge, Kylinga...smoked!
May be "old school", but it works...
Side note:
I've lost several "Partial Program" customers due to the extreme weed pressure this year. It seems they thought they could be "cheap" and still have a lawn that looked pretty much like a Full Program customers lawn...WRONG-O...not this year.
Suits me fine...
