What time of year do I apply Ornamec 170 if I want to kill Bermuda in my fescue lawn?


For spot treatments of tall fescue using Gordons Ornamec 170 Grass Herbicide with hand-operated sprayers, make applications in the spring and fall. You will start applications after green up and take care with applications to tall fescue during the summer months (July and August).  You should avoid applications when the turf is under stress due to drought, temperature extremes, or chemical injury. The rate is 2 fl.oz. of product per 1 gallon of water to treat each 1,000 square feet of turf. You will repeat application in 14-21 day intervals if regrowth occurs (may take 1-2 growing seasons for complete control).
