Here the recipe for my Chili Garlic Tea I am using to get rid of the white mould on my plants and for many different pests in my garden. I always got it in my garden shed, ready to use.
I take about 1 cup of chilies and 8-10 cloves of garlic, crash it together in a food processor, add it into about 1.5L of water. Bring it to boil, lower the heat and simmer for about 10 minutes. Take off the heat, leave until cool. Drain through the sieve and keep the tee it in a jar. Before spraying, dilute 1:2, one part of the chili-garlic tea : two parts of water. Ready is your spray :)
