ive mentioned several times about how i love trimec plus so much but im lookig to switch because its so hard to mixed...its like pancake batter.... also for this time of the year i didnt need the extra chemical in it that kills the crabbgrass. i was just at a local landscape supply store and was talking to the guy there about the trimec classic. he said that the clasic was in a pure liquid form and works great so i bought a gallon for 34 bucks. does trimec classic work as good as trimec plus. for those that use it at how many ounces per gallon is it most effective without harming the grass. i apply all my herbicides in a backpack sprayer.
