Fusarium Patch Disease (Microdochium nivale) is attacking lawns on a grand scale this year, we are seeing about 1 in 6 lawns with the initial effects of the fungal disease.
Fusarium is one of the most common lawn diseases in the UK. It usually occurs in lawns during late autumn then through winter, and can particularly take hold as the grass plant is weaker and not growing quickly enough to recover itself.
The disease spores are prevalent everywhere in lawns, but will particularly cause a problem when environmental conditions are right. When the weather is unusually mild for the time of year, and overnight temperatures are above the seasonal average, or there has been a reduction in daylight hours and morning mists, these conditions are ideal for the disease to grow.
The incubation period for the spores that cause the disease is very short and a seemingly healthy lawn with no problems can sometimes develop overnight in a lawn if the conditions are right.
The disease manifests as patches of yellow-brown grass or a white mould, sometimes known as snow mould, aptly named as the mould has a white cotton wool like appearance and it can also appear after the ground has had a covering of snow.
It is possible to minimise the chances of an attack of Fusarium by keeping the lawn surface dry where possible by have good drainage and removing leaf coverage.
Even in winter, keep your lawn well maintained and trimmed to about two inches in length.
