i saw an ad for this new chemistry pre emergent for landscapes and was looking online at the label and was impressed withthe controlled weeds. it included yellow nutsedge of all things at the medium rate!!!! i am very interested in this for next year and am getting pricing on monday, but want to know if any of you have used this or know anymore about it? we currently use Snapshot with decent results, but nutsedge is a huge problem and you can see the interest here. thanks everyone!
