    Is nut grass and nut sedge the same? Is there such a thing as nut grass?

    I am not sure what Nut Grass is for sure but have had customer call sedge by that name. The U of Florida lists three types of weeds. Broad leafs, Grassy weeds and Sedges. Common varieties in southern turf are Yellow Nut Sedge, Purple Nut Sedge and Globe Nut Sedge.

    I use manage. I was chasing nutsedge all summer. the lawn would be clean besides it:angry: I have stayed away from image since I had some spells of turf browning out. I use it to spray over varigated liriope though. I did notice that most of the problem areas were areas that held water after a hard rain. I just pray that I will not have to chase it as much this year. I have used pennant in landscape beds that were bad and it worked well. dont charge extra for sedge control because I sell weed control...its a weed...will do control on normal app and one service call... after that I would charge but it is usually under control by then..

    Manage was a great addition to our program when it came along. The old basagran days were always a pain.

    We have never had any phyto problems with Manage. YN is certainly a problem on over irrigated lawns, and it has increased in our area as home irrigation systems have become more prevalent. But it can become established and a pest on any lawn if conditions are right for the proper length of time.

    Check with your suppliers. Sometimes you can get a good early season deal on Manage if you purchase multiple containers.

    ++++Pss Manage (halosulfuron) is only good for about 6 hour after mixed. after that it is no longer effective++++

    That isn't listed on the label anywhere. If it's true, I would think they would mention that on the label somewhere.

    Think about this...everytime you treat a single lawn, typically, you'r not treating 1,000 sq ft, which requires the mixture of a gallon of water.

    Typically, Nutsedge is only found in very small patches, perhaps 100 sq ft at a time. I suppose it could be found in larger patches, but I've never seen a 1,000 sq ft patch of nutsedge.

    If the stuff doesn't work 6 hours after it's mixed, what are we supposed to be doing with the remaining 9/10ths of the gallon? Why wouldn't they mention this detail on the label?

    Thanks,
