Why does Fusarium Patch Disease develop on freshly laid turf?
Fusarium Patch Disease can develop on all turf. However, it is more visible on grass areas mown to a lower height. Consequently, it is well known to managers of golf clubs where putting greens are often maintained at a height below 7mm. Turf is mown prior to being harvested, this means the sward is relatively short (25mm) and therefore shows the signs of active Fusarium earlier than a lawn maintained at a greater height. The act of harvesting turf causes stress to the grass plants. Like any disease Fusarium has more impact on the weak and vulnerable, therefore until a new lawn becomes established it is a degree more susceptible to fungal attack.
