4 Stars

It's a Killa! on wrote

I bought SPEED ZONE last year. My yard was over-run with broad-leaf nastiness like thistles and dandelion, also spurge and creeping Charlie. I blasted my entire lawn with SPEED ZONE mixed in a backpack sprayer and in about 10 days the brown-out was very evident. Another week and my grass was regaining its vitality. SPEED ZONE seems to work slower in hot weather, which is why I only give it 4 stars. In cool weather the stuff is much quicker, which is typical of broad leaf control agents. It is post-emergent, so wait til the weeds appear before application. DO NOT MIX WITH METHYLATED SEED OIL and/or CRABGRASS KILLER as this may greatly reduce SPEED ZONE's effectiveness.
