powdery mildew and squash

Post by Fiona McGuines » Sat, 28 Sep 1996 04:00:00



Midway through this past summer some of the leaves from my squash plants
started getting white blotches on them. This soon spread to the rest of
my plants, and any fruit that was growing stopped, leaves started to
disintegrate, and that was basically the end of my garden. Does anyone
have any suggestions for preventing this next year? ( I think it was
powdery mildew). I live in Ontario, and prefer not to use any chemicals
on my garden.
Thanks, Fiona

If you start a spray program early in the spring, which consists of one
tablespoon of the following:

liquid seaweed
black strap molasas
fish emulsion
apple cider vinegar
epsom salt

spray weekly if you can on the foliage and provide good air circulation
for the plants.  The above spray is to bump up the health of the plant
which will help it resist mildew and pest problems.

If you use 1-3 tbsp baking soda per gallon of water you will adjust the
pH of the leaf surface, which will make the plant virtually a hostile
environment to the powdery mildew.
