    Since the beloved MSMA is no more, what have you found to be really effective at killing grassy weeds as well as broadleaf weeds?. Q4 appears to have very limited selection as far as grassy weeds are concerned. Cannot reseed until 4 weeks after using Q4 either. It would need to be put down within the next week or 2 around here in order to overseed 2nd to 3rd week in September.

    Used to use Trimec Plus and that stuff was awesome but it is obviously no longer sold. Iv'e looked at Drive too but it's listing of broadleaves isn't very long and it does list 9 grasses as being controlled.

    Just wondering what would be best to use as a postemergent spot treatment in place of MSMA.

    Sure. I would like to know what kind of turf you are attempting to control weeds in. What may be used on warm season turf might smoke cool season turf and visa versa.

    sorry, it would be a tall fescue. Im in zone 7. I treated with barricade in mid March, followed up with dimension toward the end of May. The lawn isn't bad but does have some clumps of a weedy grass and some broadleaf weeds. Nothing that I couldn't hit while walking around and spot spraying.

    Im leaning towards the Q4 as it's only $40 for a quart, $115 for a gallon. I figure maybe get the quart to try it. The Trimec-plus was awesome stuff but had MSMA and as you know is no longer sold.

    Q4 is your best bet. Personally, I was never impressed with Trimec Plus. Too much burn of the lawn and not enough root kill of weeds. I am in zone 11, all warm season grasses maintained at golf fairway height. I

    Yeah you're right about the burn to desireable turf with the MSMA. But that stuff worked. I would hate to buy something, spray it and have not work.

    you might want to try Tenacity maybe combined with something else. I have a friend who has been using it as is having great results on crabgrass and nutsedge, he says it's working better than quinclorac and a little better than Solitare in July.

    I'll be experimenting with my "ornacityflon" (fluazifop,mesotrione,triclopyr ester) mix very soon, to knock down bermuda, nimblewill, nutsedge, crabgrass, goosegrass, oxalis, etc. I hope it works well. I'll let you know.

    Anyone else experimenting with Tenacity mixes?

    Has anybody invented a dual tank backpack sprayer? Spray Drive XLR8 for crabgrass with the left hand and Speedzone for broadleaves with the right.

    You can mix drive with a 3-way and get very good results.
