In the UK yellow tuft has been observed mostly on Agrostis spp.

During cooler, wetter months in spring and autumn

Effects of yellow tuft

The tufts reduce the wear tolerance of the sward as they can be easily pulled out.

Tufts can also affect playability by affecting ball roll and the aethestic appearance of the grass.
