If they are huge crabgrass clumps, I would dig them up because they will turn brown after you spray them.

I just dropped some cash on a gallon of Q4 today. Wanted just the quinclorac (drive xlr8) but the JDL out here hasn't decided to carry it. I wasn't going for the broadleaf control but it is all i could find. Tests start tomorrow. Any tips or personal insight into the Q4? mostly bluegrass in alkaline soil for me...

I'm just now see some results from a Solitare application I did. This stuff is awesome! most of my crabgrass is 70% brown, and nutsedge 50% brown in 3 days. I mixed with a 1/2 rate of Momentum FX2. All I can say is, wow! I don't think I'll ever again use Q4, and might stop using Drive as well. Also, mixed with the momentum, I'm getting Nimblewill control!!

Try some Solitare...

never heard of solitare, just looked it up and did a comparison
Q4 oz of active per K at low label rate
quinclorac: .1479
sulfentrazon: .0179

Solitare oz of active per K at low label rate
quinclorac : .206
sulfentrazone: .0688

if my math is right
there is a substantial amount more active being used in solitare
and it says on the label it controls nutsedge, not suppresses it like Q4

how much for a gallon?

I got it at JDL for $112.50. They said this was an introductory price, plus I got a $15 mail-in rebate. It is a dry formulation like Drive, 1#.

Here's some pics 3 days after treatment...

first 2, all crabgrass on the top of the ditch, probably kylinga in the bottom of the ditch, maybe some nutsedge.

3rd pic, large patch of crabgrass, went over it real fast; 3 days later


give me a few days and I'll post some pics of nimblewill control!

A new product came out this year called "Dismiss" from FMC. It fries nutsedge fast.

Basagran, Manage, Sedgehammer, Q4 (at a high rate) will also kill it.

Here's what I've been using this summer:

Q4 (3 ounce per gallon rate), 1/2 rate of Dismiss, and a little LI700 for extra measure. This mixture fries crabgrass & kills nutsedge pretty quickly.

CPS (Crop Protection Services) -- formerly UAP, sells all the above.

Thanks for the advise. Sounds like a game plan!

wow that is really a high dose of sulfentrazone
i wonder how safe that is on desireable plants in hot sun?
ive seen Q4 alone burn down some nutsedge in a day in hot sun

Q4. I use it for annual grasses only.

We're seeing mid to high 90's right now, if I sprayed early in the morning or late in the evening (probably better with the wind) would I need to add some lesco 12-0-0 chelated iron to prevent browning?

Thanks.

It wouldn't hurt. Did you decide what herbicide you were going to use?
