This yr we have had so much snow, that when it melted, I had a whitish mold by the tree(yes it was supposed to be cut down march 19) Since we normally don't have winters like this, I never noticed thw whitemold. will it go away when the sunn comes out,as its only in the really shadded areas? Is this a concern, is there anything I can put on it.

It reminds me a little like powdery mildew.

There is a disease that affects cucurbits called sclerotinia white mold - causes the vine to explode in a white foam of oxalic acid. But this doesn't sound like the same thing.

If this is just a ground covering wood fungus that is decaying a dead tree then there is no reason for concern. Is it growing directy on dead wood?

It is growing on some dead wood and also some flatened grass around the tree it's in the shade,(does that matter). But in the sun the mold is not there.

The tree is hollow in the middle clear through. dead in the middle and green on the outer edges.

I did remove a large quanity of last yrs grass trimmings, last month. on the sw side of the tree next to a fence.

Is it harmful to pumpkins/squash??

Snow Mold should only be growing on & will only damage grass. White fungi growing on dead wood should pose no threat to a pumpkin plant especially since we don't grow pumpkins on wood or grass.

I have heard to rake the grasses and soil to fluff which will fragment the mold causing it to die.

Cap in the newsletter I received from Jareds nursery
they had a warning about the snow mold that Shannon
refered to. They said it should be expected this
year due to the lenght of time we had snow on the
ground. They recommended as the Wiz said to rake the
infected area and areate to increase the available oxygen.

Captain,

Are you trying to grow quality turf here? If so, the easiest correct fungicide approach (for prevention only) is PCNB granular. If the damage is already evident, then the above recommended light raking is fine.

I thought you saw this "white mold" in a future or existing pumpkin patch.
