Reduce heat stress
Raise height of cut and mow less often. Consider the use of light hand mowers, especially on the clean up cut. Do not be tempted to over water. Syringe or hand water problem areas to prevent wilt. Avoid top dressings, pesticides or fertilisers. Thin trees and under-brush to promote air movement as this will increase transpiration and help the turf to cool itself. Again intensive heat stress during the summer can leave the sward thin and weak going into the autumn/winter period making it more susceptible to Fusarium Patch.
