today I was cleaning up weeds and grass around my 950 boyton, it's in a 4 by 5 foot oval of dirt surrounded by grass. We have had a rainy year, and I noticed what I think was powdery mildew on some grass 3 to 4 feet from my plant on the outer cirlce. Never ever seen this on my grass before ever. It looked like white snow on the grass in spots and all over it in some places. I slowly pulled the grass out by hand, and when doing so, some white powdery stuff few into the air. I have never seen powdery mildew puff like smoke in the air before. Anyway, the 950 looks very healthy and no mildew anywhere I can see. Can someone confirm that this white stuff was pm and if it will affect my plant? Or if the white stuff that went into the air could affect my plant? It's got 5 true leaves and I think it's too you to spray with anything. All the bad grass is gone now, so if I don't get any pm from what I did, I think I'm ok. Any suggestions are welcome. Jimmy

I did a general research about grass powdery mildew on the internet, I definitely think that's what it was. I think from what I read that it's a different type of powdery mildew and doesn't seem to affect most other plants (I hope pumpkin plants are included), can someone confirm this for me who knows about this stuff? It definitely was a strange type of PM since it went into the air in white puffs when touched, no pumpkin PM has ever done that to me. Jimmy

The mold on the adjacent turf might just be a slime mold. Regardless, if conditions are present that favor PM or Slime Mold get a fungicide application on the Pumpkin.

Rip the grass out too! LOL

FIVE leaves is a young plant. Use a fungicide at HALF the lowest rate & repeat that treatment again a day or two later. Spray only in the cool of early evening.

I would really get ALL that grass out of there. Grass & Giants don't mix real well so far as I have seen & experienced.

I believe the slime mold is correct, also known as snow mold. I looked it up, it looked just like snow on my grass and it comes off when touched. The good news, slime mold won't affect anything, doesn't even harm grass. Tremor, it's just a fun and genetic's patch in my parents backyard, the grass isn't going anywhere:) Thanks for the help.

Ok just a question about powdery mildew is it host specific or will mildew from say a lilac spread to pumpkins? the reason I ask is they taught in the master gardeners class I took that it was host specific but I still have doubts about that.

PM is host specific. But the conditions that favor the deveopement of one variety also favor the others so....since the spores are airborne, when one is seen, another is right behind it.
