Leaf Dieback

Disease infection can cause grass leaves to dieback, however, a common cause of a grass leaf dying back is due to its natural lifecycle, from being a young leaf, to maturing, aging and then senescing (aging without cellular division), which results in dieback, progressing from the leaf tip towards the base of the leaf (basipetally).
