sprayed it on my lawn three weeks ago, 3oz / gallon with 1 oz dishwashing liquid as surfactant. No results. Sprayed again last week, 4 oz / gallon with Southern Ag surfactant. No visible results. Bermuda grass, central Alabama, no appreciable rain before or after. Didn't cut grass 3 days before or after. Any idea why no results? too early? Thanks
