Macambrose and others interested-- 10 days following application of revolver @ .6/K on heavy dallisgrass shows significant action, but no kill as of yet. Revolver seems to be performing as well to side-by-side comparison of msma @ 1.5 oz/K . Revolver made no burn and dallisgrass has a classic "purpling" symptom. I will rate the test once more in 10 days. Previous experience with revolver on fescue was that it is very slow. Plot was applied with 40 gpa through zspray. Area has received over 5" rain since application. Economics will make revolver a tough choice even if it is eventually labeled for dallis.
