Description of Disease:
Leaves fold up, reddish in color, white powdery growth on buds and leaves,
blooms fail to open or fall off, stunts plants.
Causes:
A fungus which likes moisture in air and soil, caused by dead soil, eco-system,
chlorinated city water, using high nitrogen fertilizers (urea based), poor health of
plants due to improper nutrition, over head watering encourages fungi to spread, planting
wrong variety /wrong location
.
Low Brix
Testig plant will result in low Brix reading.

Immediate Solutions:
Reduce over head watering, provide soaker or drip, apply compost
and mulch , Use a Garden Filter when watering to reduce chlorine
in soil. Use Bacterial sprays such as Nitron A-35, Shure Crop, Superseaweed,
Agri-Gro etc. Making Your Own Enzyme
/ Bacterial Spray Spray a fungus spray such as garlic, add 5
drops garlic oil to 1 quart water, add 2 drops Dr. Bronners Peppermint
soap (as wetting agent) or use Jungle Rain...1 Compost tea spray
will also encourage beneficial bacteria. See compost tea page. Compost
Tea Page Baking Soda is very effective for this type of problem.
Use 5 tablespoon baking soda 1 tablespoon vegetable oil or ultra
fine oil or fish oil; 1/2 tablespoon Dr. Bronners Peppermint soap
(or Jungle Rain) and 1 tablespoon vinegar. Into a cup first add
enough water to fill 2/3 of the cup, add the baking soda, vegetable
oil, soap, fish oil stir then add the vinegar (in that order). Apple
cider work well here too. Dissolve together then add to gallon water
and pour into sprayer. Spray on leaves of roses.
Short Term Solutions:
Composting/mulching several times per year, controlling water thru soaker or
drip systems, using a garden filter when ever possible( see garden filter page).
Proper Nutrition:
Use no chemicals, no high nitrogen fertilizers, use composted animal manures,
use organic fertilizers, natural sprays.
Long Term Solutions:
Proper composting and mulching, soakers or drips system used best with inline
feeder systems, use beneficials (like beneficial nematodes), use only organic fertilizers
(buy or make your own), use natural foliar, encourage earthworms, companion planting.
Fine horticultural oil will work here in keeping the spores from spreading. Should be
done in the early spring as the earth get warm.
