There are people who say "spray fungicide" at any possible sign of fungus and there are people like me who refuse to use it. Nitrogen exacerbates fungal problems, so it's generally good to hold off on fertilizer if you suspect fungus. However you may have had nitrogen deficiency and needed some. Thank goodness you didn't use the urea! Milorganite for the most part is slow release. Try keep the grass blades dry, so if you need to water, do it early in the day so the grass can dry off before evening. If the problem looks like it's spreading and you are worried about major damage, here is some information on the kinds of fungicide least damaging to the mycorrhizae fungi: fungicides and mycorrhizae You had a soil test last year. Did it say you were low in potassium? If you were, Milorganite doesn't provide any. You could use potassium sulfate 0-0-50 to supplement the Milorganite. If the soil test did not indicate a deficiency, don't worry about it. Some general info on mycorrhizae: Mycorrhizae: so what the heck are they?

Hi- A few of us are located in NNJ also. We've been having the same problems as you. It's just been a bad year for lawns around here. I also applied Bayer and I think you're supposed to repeat it after 14 days. I would pull those weeds by hand making sure to get the roots and bag them up.

J4c11, Thank you for all your help this summer, never had to deal with fungus that bad

Not enough info. Please describe your lawn more in detail. Looks like you have kbg. I can tell you 4 apps of milorganite isn't going to cut it. You need to hit it hard in the fall with synthetic fertilizer. Is your lawn shady?
