Sounds like a common lawn disease that we frequently encounter in New Jersey called "Red Thread". As the disease advances, areas of the lawn tend to take on a dark pink to reddish cast on the leaves. It is a disease of stress which means if your lawn is being stressed by anything that limits or impedes its normal, healthy growth, it is going to be more susceptible to a disease than a normal, healthy lawn. The following are a list of factors that may ecourage "Red Thread"
* improper soil pH ( a measure of how acid the soil is) --- too low (less than 6.2) or too high (greater than 6.5)
* lack of or low levels of certain nutrients in the soil
Remedy - Get your soil tested at the Rutgers Soil Testing Lab. It costs around $15 and is well worth it . It's almost like getting bloodwork for youself when you go in for a physical and it gives a good starting point to help diagnose lawn problems. Their website is: http://njaes.rutgers.edu/soiltestinglab/ --- follow their recommendations !
* too much and too frequent moisture: The longer the grass leaves stay wet, the easier it is for fungus to get started and spread. If you have a sprinkler system, make sure it is not going on more frequently that 1 to 2 times per week.
Remedy - Water deeply and less frequently. Check out this Rutgers Publication : http://njaes.rutgers.edu/pubs/publication.asp?pid=FS555
* your soil is too compacted which makes it tougher for turfgrass to thrive
Remedy - Aerate your lawn in late summer to fall by core aerating, not spiking. Thatch your lawn also if needed
Read the Rutgers Publication on "Red Thread" : http://njaes.rutgers.edu/pubs/publication.asp?pid=FS555
Fungicides are available that we carry in season whch will halt or prevent the spread of this disease, but in the long run you'll be better off if you can correct the problem that might be causing your disease problems. Bring in a sample next Spring if it shows up again and we will properly I.D. it for you. We can also do a pH test for you, but I would advise getting the soil test done by Rutgers and then bring in the results and I'll interpet for you and steer you in the right direction.
Good Luck --- Mike
