Powdery Mildew Control

Post by Bill » Wed, 11 Sep 2002 14:42:51



I am getting good early results with a spray application of about 2T
bicarbonate of soda / gallon of water in a pressure sprayer. (I have filed,
but not yet used, the whole milk / corn meal suggestions.) I am wetting the
leaves of my cucurbits to the point of run-off and making some effort to
get both sides of the leaves.

After the first application there was a noticeable decrease in infection
after about 3 days. Have just made a second application (5 days) for a
follow-up. Will continue until either the infection is all gone or I see
some contra-indication.

The bicarb does not seem to have had any effect on the bean blight. I did
not see many bugs on the beans this summer (3 bean beetles and one
grasshopper) and only had light chewing damage ... but apparently that was
enough to spread this disease over most of my trellis. Thus far I have
gotten 71 pts from 16ft of trellis and it looks like I might make my goal
of 100 pts ... but only just barely.

Last year this place was (literally) swarming with ladybugs ... but where
are they when I need them?

I have noticed a fine grey deposit on my hydroponically growing tomato
leaves. I think it is mineral deposits from nutrient sent through the
leaves, but I really do not know. the problem seems greatly diminished since
I cut my water cycle to about half an hour every 4 or 5 hours.

RD ... For whatever miss-shapen reason, my news reader choked on your
reply, spit it back into the ethernet and I have been unable to coax it to
let me take a look at it. Care to repost?

If this happens at some point in the future, you should know that
google offers a wonderful usenet search engine that is quite
user-friendly & deep, having incorporated dejanews.

http://www.google.com/grphp?hl=en&ie=UTF-8&oe=UTF-8&q=

By clicking on "advanced group search," you wind up here:

...and keywords, titles, posters or groups, single or in combination
can be used. I love it, myself.

Look at the newsgroup rec.garden.hydroponic. It should still be there.
