| Hello. I seeded a week ago today with Jamboree turf type tall fescue. It's growing quickly and nicely, but I dumped a bit too much Milorganite in one area of the lawn and the picture shows a white fluffy growth on the soil. What do you think this is, and is there something I should do about it? I used one bag each of Milorganite, Lobster compost, Dr. Earth compost, and another compost for about 2,000 sq. ft. My soil test was pretty good, and I want to stay as natural as possible, so I figured I'd just supplement with a bit of compost and some phosphorous from the Milorganite which is 5-2-0.
Thanks! |

| That is fungal mycellium, which is pretty common with Milorganite, and is usually harmless. If you get white growth on your grass, and it starts to die, then that's a different story. That is generally indicative of a pathogenic fungus, most likely pythium blight. |
|
| Whew! Thanks so much! Should I try to remove it where I can, or do you think the grass will grow through it? |
|
| No, it will go away soon enough. Just keep an eye on your grass for disease. The risk of disease is higher in warm humid weather. |
|
| Will do. Thanks for the reassurance! |

| I have a similar issue I am hoping everyone can help me out with. I overseeded about 3 weeks ago now and the grass has come up wonderfully. However, we have had a lot of rain lately without much sun and I feel that this has caused a similar white fluffy fungus to form in some small spots on the lawn. Unlike easychair it seems my fungus is killing the grass. What should I do? Should I fungicide be applied even though the grass is still young? If you dont feel it is the rain and a different cause please let me know. I am not sure what would have caused this as I did not do anything out of the norm for overseeding and it is very secluded small spots where this fungus is forming. Thanks for all your help!

| After looking up pythium blight as mentioned by timeco I think that is what I have in my grass. I think all the rain, morning dew, and overall humid weather we have had the past week has contributed to this. I would like to stop it in its tracks before it spreads. What are some recommended fungicides that I can pick up at my local big box today to make sure that this does not spread more? Thank you. |

| I doubt you will be able to find anything at a big box store. Most of the stuff at box stores is overpriced and very un-effective. Heritage (Syngenta), for example, is a good product, but I've never had experience with it on pythium. There are other products that should work pretty well, Heritage is just one product. I recommend calling a professional to apply something for you. All fungicide is extremely expensive, and it should be applied precisely. |

| Thanks bassplayer. I was planning on getting some Heritage but unfortunately with the store hours and when I get out of work I will not be able to pick it up until this weekend. Closest location that currently has it in stock is 60 miles from where I work so not something I can do at lunch. I understand that the Home Depot products are not ideal but being that I am limited in my situation is there a product that anyone could recommend as the "least uneffective". I want to just get something down now to prevent any potential further spreading. |

| I agree, that looks like pythium, which is common on young grass. Heritage would be ideal as would Subdue Maxx and Banol, but again, doesn't sound like you can get to the store in time. The only thing that might help is Immunox, which you can get at Home Depot. It comes in a black hose end sprayer. It contains a pretty good fungicide, but I don't think it is that effective against pythium. Fungicides generally don't hurt new seedlings. If you don't want to use fungicides, just cut away the diseased areas as carefully as possible with a pair of shears. Cut the blades close to the ground taking care not to touch the surrounding healthy grass with the diseased. |

| Thanks timeco. I actually picked some up at lunch per an old thread I found where you recommended it. I will give that a shot at least for now to stop any further spread until I can get something different/better and then either later this fall or next spring I will give the cornmeal regiment every 3 weeks a shot since it seems people here on GW seem to like it as a fungus preventative. Do you think I should try to reseed these areas after taking care of the fungus or at this point do you think maybe I should try to dormant seed the bare spots this winter since it is already getting into October? Thanks. |

| Occasionally after a Milorganite application during periods of warm to hot, humid, nearly wind-free conditions a homeowner may experience a white mold growing on their lawn. This is not a disease that will hurt their turf. It is the soil microbes, primarily fungi, attacking the applied organic portion of Milorganite and beginning the breakdown of fertilizer into its� nutrients. This will disappear on its own in a few days. To make it disapear quicker you can (a) water the lawn to �push� the Milorganite and mycelial growth onto the soil or (b) mow the lawn to break up this mass. |
