Description: A leaf spot appears to be a tan-like circular form at the edge of grass. These lesions cause turf to dry out and discoloration is apparent in some areas, it is called the melting-out phase. Leaf spot is caused by a fungus that breads in moist areas, and spreads its spores by wind and water. Peak season: Spring to fall. Treatment: Fungicides. Fungicides are applied early spring or in the fall. The initial phase of disease process would turn grass blades into oval, purple-brown lesions. The spots enlarge until the whole blade turns to brown killing the entire plant. When will I see leaf spot? The fungus becomes active in wet conditions, during spring there are release of spores that can be distributed to the atmosphere by water or wind (fall). The distributed spores may infect healthy grass that will create new infection. The spores may also me washed down to soil creating infection to roots and crowns. How to get rid of leaf spot and when will take? It usually takes 2-3 weeks to get rid of leaf spot. Rake leaves and remove all affected plants to reduce chances of infecting to other areas or plants. One of the best ways is constant mowing of your lawn. Maintain a right height of grass. Use the one-third rule. Make sure glass blades are sharp and not dull. Dull blades tear the grass off inviting more fungus. How to prevent leaf spot from infiltrating my lawn? Too much of something is bad enough. This also applies to lawn care.
