guttation water and baking soda

    Has anyone tried to knock of the dew and guttation water (water that
contains a lot of nutrients for a fungus that may help disease invade a plant
easier) off their plants with a light watering in the early morning?  We do
it on golf courses as a method to reduce the chance of disease in the
summer.

    I thought it might work for AG's on mildews to reduce spraying
frequency.

John!
     This word guttation water or dew is an interesting topic. Do you mean to
suggest if we foliar feed and leave nutrients on the leaves when they combine
with the nights dew we are actually increasing our chances of diseases like
powdery mildew? If this is the case your going to change a lot of peoples
spray programs going into late summer. Mine for one. Have you read that
Cornell U. has discovered that baking soda mixed with a sticker solution
sprayed on leaves has provided outstanding organic control for a wide range of
common fungal diseases? Including, black spot, POWDERY MILDEW, leaf
spot,anthracnose, phoma,phytopthora,scab,and botrytis. I know this treatment
is cleared for ornamentals and fruit trees. Someone needs to call Cornell and
find out if they tried it on vine crops and at what %. Just think how much
money us pumpkin growers can save and how much safer can you get than baking
soda! I would like to have you try it on your golf course grass when you spray
off your greens in the mourning. I believe liquid seaweed acts as a sticker
agent and is known to help prevent powdery mildew, I plan to use them together
this year and I'm hoping they make a killer solution against mildews. With
your background it would be great if you called Cornell and reported back to
the group. Isn't it great what we all can learn from each other and this page.
I've enjoyed your input and respect your reconciliation with Wayne. He has
helped a lot of growers, has written many articles and donated a lot of time
to our local Topsfield weigh-off. One article he wrote everyone should read on
how to mix your own fertilizers and get the % you want. Few people have moved
this sport forward as much as Wayne.     Alan R.
