Garlic fungicide: several garlic cloves (mash, pan simmered, cooled & spray)
Garlic spray acts as an insect deterrent also, encouraging insects to move on to more appetizing plants. Unlike many other types of insecticidal garden sprays, garlic can safely be applied to the leaves of plants. Drop the cloves from an entire bulb of garlic into the blender along with two cups of water, puree until finely blended and set it aside for a day. Then, strain out the pulp, mix the garlic liquid with a gallon of water and add it to a sprayer.
