Leaf Spot appears on the leaves of some grass plants. The species most likely to be attacked are Smooth Stalked Meadow grass and Ryegrass.
Leaf spot occurs in the summer months when temperatures are high and conditions are humid. Minor infection may result in lesions on the leafs. The infected area is normally brown in colour, as the infection progresses the colour in the surrounding tissues changes. As with other turf diseases the leaf tends to turn a pale brown or tan colour. If the infection moves down to the leaf sheath it will die resulting in thin strands of grass. In advanced stages where many plants die in large patches it is known as 'melting out'.
Leaf Spot is the common name given to a large number of lawn diseases caused by the same family of fungi. Several fungi may be responsible but it is thought that Dreshlera is the most likely.
