    Brown patch can spread to other lawns via lawn mowing equip. But the brown patch issue is not within the scope of your responsibility. Treatment of brown patch will fall within the scope of the state licensed treatment company that provides the condo complex with this service. You need to be capable of communicating professionally and clearly that despite the fact this condition can be spread from lawn to lawn the treatment and preventable measures for it is not within the scope of your responsibility. Applying lawn fungicides on a commercial scale requires state licensing that you do not have so controlling or preventing the issue even if you wanted to is not possible. I suggest you educate yourself as much as possible with this issue before you meet with the condo management. Also applying fert to a lawn with active brown patch is like poring gas on a fire. If you want detailed advice on how to communicate your side and deal with the condo management you can PM me. go to this website and start reading. What ever you do do not take a defensive tone with the condo people maintain profeshinal curitisty at all times. You have common sence and the law on your side. you just need to communicate this in a clean and clear way. This is just 1 place of hundreds to get good info.

    Sod webworms & cutworms are active right now. Annual white grubworms too. Then there's soil compaction w/heavy clay soil & foot traffic. Core aeration never hurts.

    Is it dry up there, when's the last time it rained, and how often are you cutting?

    Because maybe you're cutting it too often and or too low, at least half the time that is the reason for 'brown patch.'
    I'd say even if irrigated it should be on 10-12 days, maybe 12-14, but I don't know.
