Any ideas what's wrong? It tarted off one patch but it's starting to
spread. I water and feed the lawn on a regular basis

Hi. Might i suggest that you could find the answer on Pg 50 of the book
'The New Lawn Expert' by Dr D J Hessayon. *Published by Expert Books.
Its about a fiver on Amazon. Well worth buying. It LOOKS from the
pictures in the book like 'Red Thread'

Nothing in that picture suggests that it's likely to
be Red Thread to me. They are just small dead
areas of turf which could be do to a long list of
possibilities. Additionally, I don't know where the
OP is located, but RT tends to occur at cooler
temps, usually spring and fall. Also, it usually
doesn't kill the grass, it justs effects the tips and
the rest of the plant lives and recovers.

It's easy to identify, because it gets it's name from
the fact that the fungus exhibits as the ends of the
blades shriveling up into what look like red threads.





The treatment being a systemic
fungicide such as carbendazim plus other general measures but dont take
my word for it!!

A general fungicide could be effective against a lot
of fungus diseases, so that could work even without
identifying it. But it could also be insects.

Another thing is what are the watering and fertilizing
practices? It should be watered deep and only
a couple times a week when it needs it. Water so
that the watering finishes around dawn. That way
you minimize evaporation loss and leave the lawn
wet for the shortest amount of time.

Worse thing for most diseases is to leave it wet
overnight, over watering, fertilizing dooring higher
summer temps.
