I can buy sulphur powder off ebay. What is the best method of
application ? - can I dilute it with water and spray as not sure how to
go about dusting the plants. I will definitely need to disinfect/bleach
the greenhouse before next growing season. I guess diluted bleach could
be sprayed over the greenhouse but how do I effectively treat the soil
?

The mold type is not as important as IDing it as a fungal as opposed to
other problem conditions.

Gray mold can be brownish in color so don't let the color be a key indicator
and it can get into the fruit, usually through the stem section. The
fruit's hard waxy exterioris the tomato's best protection. Be aware that
this can infect your post-harvest fruit, although a vinegar/water wash (
high acidic pH) will usually help w/ control in the kitchen.

After reviewing the pic here, do look around this site a bit to help your

As I have said previous, start a Preventative Maintenance program ( PM).

Sulfur use; complete dusting coverage is a bit difficult, good burning
equipment is another 80-100$ US and leaves a smell and a film on the
"glass", cannot use it outside. You can use a metal plate over a candle,
but.........Spraying is best and I can use it around the yard as well.

a small bag of Sulfur (10 lb. ) is about 10$ US

4 tblspns per Gal (US), do follow all the directions as sulfur can cause
damage to sensitive plant.

I just picked up a nice quality quart/liter sprayer for ~7$US, Easier to
use and I don't have to use the gal sprayer. {I save it for my fruit trees
}

Make sure not to apply when it is too hot and within a week or so of any oil
spray

so as to have full disclosure, here is the scary scorecard results of
Sulfur, a naturally occurring product:
http://www.scorecard.org/chemical-pr...e_id=7704-34-9

Cooper is also considered a good product to use and the Bordeaux mixture is
one I want to explore a bit more before trying. supposedly messy.

or http://www.garden-services.com/bordeaux.html

Copper is used here in the PNW as an algaecide(sp?).
Scary part:

Been in the 90-100f here the last few days and then expected to be back
around 55f again when the rain returns next week. I do use misters 2 x a
day when the full sun is on the house, the rest of the time it is filtered
sun. lot of opportuniuties for mold.

So far, 2 simple Sulfur sprays early on and a follow up PM program of neem
oil @ 7-10 days has worked well for me. As the climates change I may have
to as well.

I do not use the baking soda trick
http://www.oisat.org/control_methods...king_soda.html
as it is more sodium (salt) and absorbs more quickly than potassium salts
potentially causing uptake problems and a sodium overload leading to
conditions like Blossom End Rot. I believe the bicarbonate solutions are
more useful in soils as the soil buffers the salt uptake a bit better than a
hydro system. You may want to consider some of these tricks.
more info on the different bicarbonates
http://www.attra.org/attra-pub/bakingsoda.html

Try the Potassium Bicarbonate first.
http://www.planetnatural.com/planetn...carb-label.pdf

Course the Organos cannot use some of the bicarbonates such as ammonium
bicarbonates which have synthetic. There is also a danger in a using
bicarbonate "fix-alls" in alkaline soils as well as hydro systems.

Disinfectant/sanitizer : Bleach; not the greatest but half life is quick

1 unit to 9 or 10 units of 5.25%, sprayed.(read labels of household bleach,
strength % vary) get the pots and tools also

very low ppm use

Soil: are you growing in the dirt... in the house? Major expense/labor to
clean 36 sf of soil, best to layer some mulch such as fine wood chips and
skip that next year, and maybe the next . Nature will take care of most of
that in that time especially if you sprayed. Meantime try using grow bags,
rockwool or some form of hydroponics ( rain gutters PVC pipe, wood boxes
lined with plastic) or fill sand bags, a few trash or recycled grocery
bags
( I do not mean to sound simplistic but make sure there are drain holes) or
some
5gal/ 18 ltr containers,buckets, etc with a soil mix for each plant next
year. what is good here is that you can easily remove any plants that are
going
bad and replace them. Then set up a drip irrigation system, a timer and sit
back .

Try soilless, add a nute reservoir, a pump and you got Hydroponics.
'ponics are a lot of fun for tinkers . That is a whole 'nother chapter,

This is long and hopefully not too disjointed.
If you can't find an answer, ask.
Would like to hear of your efforts.
good luck
