Note the lesions and discoloration of damaged blade.

Column TwoWhenever the humidity level and the temperature combine to total 150 or more, the conditions are right for the development of fungus pathogens. Brown Patch is one of these and can be recognized by leaf blades first appearing water soaked and dark. Leaf blades then wilt and become light brown as tissue dies. A leaf lesion may appear irregular in shape, tan in the center and dark brown around the borders. Symptoms on high cut turf may resemble a ring with centrally located tufts of healthy grass within the patch. Fescue grass is most susceptible to this disease. Over-fertilization tends to increase the intensity of this disease. Seneca Gardens' Summer application is a very light, control-released application of fertilizer. Preventative applications are usually not economical in residential lawns. If you notice Brown Patch in your lawn, we can help control them with supplemental applications of fungicide. Seneca Gardens rotates the products we use on your lawn to keep a resistance from building up to any one product. Something you can do to help prevent this disease from taking hold is to mow your lawn frequently with a sharp blade. Also, avoid evening watering and trim trees and shrubs to allow for better air movement and light penetration.
