control fescue

I used some corsair several weeks ago, it worked, but is VERY SLOW, I wondered if it had worked at all. It is very expensive $35.00 for 2 oz @ .2oz/1000 $300.00 per acre.
I have just tried some REVOLVER, it is labeled for killing fescue. Max rate is .6 oz/1000 for a cost per acre of around $135.00 it is susposed to work faster, faster even with hotter weather. You can only but it in quarts.

I am going to compair the two in the next few weeks, revolver is a newer chemical.

I can not give you any specifics on either really I have given you all the info I know.

I have not used either corsair or revolver on turf. There is some pretty good info on both on

Chlorsulfuron (Corsair) has been around a long time as a wheat herbicide (Glean), but has major drawbacks on the farm because of crop rotation limitations on label.

I hope you will post results on your experience with revolver.
