    I sprayed grassy and broad-leaf herbicide 12 days ago and we have had a nice amount of rain lately. I'm planning on aerating and seeding with fert in a couple of weeks. Directions 3-4 weeks after spraying PBI Gordon's' Q4.

    No way of telling from those pices...would have to se the blades. It looks like dollar spot, though.

    Is there anything I can do now for it?

    Or should I just aerate, de-thach and fert.

    Thin line on taking care of it now or waiting till spring. The fung will slow down in cooler weather but will still remain present through out. I personaly would sell them on fung control this fall and hit them up again in spring. I would continue with the aeration and over seeding only if I put fung control down as the new seedlings will be more apt to catching it if they are not disease resistant.

    Roger that on the fungicide. I put down Clearys 3336 turf fungicide back in July so I thought that would cover me for this year.

    What do you guys recommend for fert right now after applying herbicide?

    Joe I heard you mention on another thread about a hight potassium fert for thicking up the grass. I usally use Lebanon Turf's Proscape Mesa 19-0-6 for my final fert of the year. It's a slow-release that last couple of monthes.

    I open to any suggestions. I've researched a ton but I'm a little new to this area of lawn care.
