In terms of bluegrass, im assuming your meaning poa triv and poa annua? If so i know velocity is used up here to take poa triv and annua out of bentgrass, rye, kent blue, and fescue. Im not entirely sure about bermuda since its not really that common up here on golf courses. This product porbably does cost a good amount, but just thought i would mention it.

Indeed, it is Poa I'm referring to not the other blue grass.

I do not understand why each individual's state doesn't provide or allow access to information involving what chemicals are available and what they are for. Each year, I obtain a new MP booklet from our state extension services. (I can go online and read the text from the state website). The first book is free and each copy after that is 15.00. It will list all chemicals available, their usage, their rates, their common and trade name, and especially the cost associated with their acid equivalents. The only information that is not listed is a supplier for the chemical.

Now we are talking I'm familiar with revolver, but was told by lesco that it won't kill it being that my window is closing on the dormancy of the bermuda we are getting some green up i was told not to use round up due damage to the starches in the grass? How about some good ole topical burn (scythe) with a half rate of round up?

Rat,
The use of scythe and glyphosate is the total fast burn down non selective combination. It will suppress poa annua alone but combined with gly, it should burn it down and kill the roots. Why not Duel (gly and diquat dibromide) either way, It will burn down green sprouts of bermuda and you will notice slower green out.
I use gly alone in my tanks for dormant muda. It takes a little longer to react in cooler weather but once the temps jump up, the poa falls down. I am still using gly right now to burn out bermuda lawns. If it is a risk you are willing to take, it is less expensive to use your method. Sometimes, it leaves you in poor posture explaining the slow green up.
If I am not mistaken, Pelorgoric acid is the same combination used in roundup weather max. Sorry if i am wrong as i havent used it in a while because of expense.

Ok info is power and reassurance is even better these are the first full bermuda lawns I've had to maintain, fescue is the predominant grass here for now, so warm season is a
whole nother culture mowing height ph etc... Green to clarify you said my method is less expensive but i think you meant yours since scythe is not cheap atleast not on a commercial application. or did you mean duel?

I need one of those books. I've always just done my own research to get my answers. It's a little risky to be spraying blanket apps of Glyphos here. The bermuda is starting to wake up along buidings, streets and sidewlalks. I sprayed Sencor (metribuzin) on one yesterday. I've had great results with it in the past...on bermuda lawns with Annual Bluegrass.

Thanks Ted here too we ware getting some green up on the concrete edges and the south side exposures. I should have mentioned that it is only spot apps that are needed. I too need to check the coop extension to see if we have such a valuable tool. Hopefully my liscense money is going to good use.

Ted,
I have the MP-44 booklet. The greatest booklet for the State of Arkansas!!

Grass,
I don't want to mislead you as It must be understood that in our delta area of Arkansas, we are predominantly Agriculture. However, these booklets are given out as training aids from the state. These books were kept a secret by the pro's when I was learning to study for my exams and it was the state plant board that directed me of the existence of these books back in 1990. They are still being printed for commercial suppliers, agents,etc. but they are viewable online.
Your state should offer such material to its professionals. That is why I may come across as harsh when other members that are licensed ask some of the questions as such. I am under the impression that with such stringent laws and rules other states have, that they would offer educational information to those that are levying them laws.
It isn't always completely practical to take the advice of sales tech's from Lesco, JDL, and other such corps. Please forgive me if I am wrong!!!!

I bit the bullet and went for the revolver :):), the good news i found it $ 60 a quart cheaper than lescos price, the bad news is they are a bunch of scam artist if others can still make a profit at $60 less, i gave, as in past tense, alot of business to them thru out the year we only service commercial multi-family and use alot of product but i guess not enough to get that kind of pricing thanks everyone for your input and time
