Leaf spot

Leaf Spot or Melting Out (Drechslera poae) is a turf disease that occurs during warmer seasons.

Turf under drought stress, high nitrogen and a close mowing regime is most susceptible, especially if the foliage remains wet for an extended period.

These pathogens commonly cause disease in complex with other fungal pathogens. Affected turf exhibits a general browning and melting out (thinning) resembling damage from drought.

A closer inspection may show die back of the leaf tip, with the browning gradually extending down the leaf and subsequent shrivelling.

Circular lesions with dark brown margins and tan centres may be seen on the leaf.

The crown and sheath can rot, which can result in a thinning of the turf.

It is difficult to give general advice about this disease, therefore it’s recommended that advice is sought from local ICL Technical Area Sales Managers.
