    better to figure out what fungus it is and why it is appearing every year.

    liquid i've heard, but i don't mess with fungicides much.

    aerate and control the thatch layer.

    Most fungus can stay active in the soil for many years.

    We use Eagle or Lesco Manicure both liquid for spot and blanket apps.

    Eagle is a better curative. Manicure,preventitive.

    Armada is awesome. You can use Manicure on residential?

    liquid is almost always better, but I agree, I don't like fungicide apps.

    Eagle is weak on patch diseases, better on ornamentals.

    We use Manicure as a preventitve at a pharmaceutical company we maintain.

    As far as residentials we dont have much of a call for it.

    Noone wants to pay for preventitive apps until it's too late.

    be careful with eagle it is known for allowing resistance to fungi.
    thiophanate is a good alt.

    If it is really yellow and if it occurs in late summer or fall--it could be rust fungus. Some ryegrasses are very susceptible to the fungus. See:

    Extra fertilizer is the best cure for rust. It also disappears about the time of frost.
