Answer 1

I had that problem with my pumpkins a couple of years ago. Killed every last one of 'em. Later I found a magazine article in a journal called, Texas Gardening, and it was all about planting pumpkins... the stuff is called powdery mildew.

I'll see if I can find you a treatment for it:

Here is an article all about it, with control ideas as well... http://www.ext.vt.edu/pubs/plantdiseasefs/450-710/450-710.html I think our problem was that we planted a bunch of pumpkins in too small a space.

right this is all i know, and that i've got completed organic and organic gardening for years... I gave this answer to a distinctive question besides... Organically i might recommend to make a mixture in a blender then siphon it, place it right into a twig bottle, spray it onto your vegetation, right this is the combination: 4 cups pink warm peppers 4 cups water yet another organic and organic approach is kinda gross besides the shown fact that it relatively is stable adequate to get into the organic and organic encyclopedia of gardening I study a lot: a mixture (mixed and filtered) of the bugs and water, spray them on the vegetation. What labored for me became right into a sprinkling of fireside ashes each time when I watered the squash. I did it each and every time and each and each plant lived. Now they're relatively massive and the bugs are no longer any hardship in any respect. (to maintain it organic and organic I constantly used sparkling organically grown o.ok.to burn and those wood ashes are organic from a hearth which isn't used for the chemically dealt with woods bought in shops) I had tried a mix of garlic and water and it did no longer something. I additionally tried a "bait crop" and that they've been given eaten too today, besides the shown fact that it only approximately labored to detract the bugs to a distinctive area on the plot. I planted seeds a million inch aside alongside the distant fringe of the plot the place i became into no longer likely to strengthen squash. They went there and my meant squash had a hazard to stay to tell the story. quickly the bugs only figured it out and attacked the vegetation. I relatively have additionally tried planting marigolds between each and each squash plant, they have been exceptionally and now they're very fortuitously transforming into however the bugs are nevertheless there. i'm going to have had the incorrect flower, or they could be proof against the marigolds. source(s): The encyclopedia for organic and organic gardening

Answer 3

Powdery Mildew, or Downey Mildew . Has it been very humid?Especially if that came after a period of drought stress. Clean up any infected leaves . Thin some , if needed, to help airflow. When you water, do it at the soil surface, keeping the plant dry . Spray with a solution of 1TBS/gal baking soda , + a little dish soap ( to make it stick) This is to prevent new, doesn't cure any infected parts . Check stems for holes at or near the soil line , & for the squash bugs that make the holes. That could weaken them enough to get diseases. Bury stems whereever possible, so that they root, & if one part is killed, you won't lose the whole thing.
