The first known UK case of Gray Leaf Spot disease on perennial ryegrass has arrived in Britain!
This is potentially the most damaging fungal disease for this grass variety – and it’s a problem that can be extremely difficult to control.
As a disease of amenity turf, Gray Leaf Spot is a problem which has been prevalent in the USA and over the past 15 to 20 years, it has progressed through much of mainland Europe.
In August 2020, however, The Turf Disease Centre confirmed the development of Gray Leaf Spot disease in a UK sample of perennial ryegrass turf.
This was the first known occurrence of the disease in UK perennial ryegrass and the importance of this outbreak should not be underestimated.
