To make a batch of the extract, simply mix one part well-rotted compost (that contains a mixture of plant matter and animal manure) with six parts water. Stir well. Let the mixture stand for about a week, then filter it through cheesecloth. Spray the liquid (undiluted) on plants, or use it to soak seeds overnight.

The German researchers say that compost extracts cause surface concentrations of phenols (chemicals that are toxic to fungi) to increase considerably. This results in induced resistance to fungal infections. Extracts from compost containing (any kind of) animal manure result in much better resistance than ones from only plant material.

Plant resistance typically declines about seven to 10 days after treatment, so for best results, repeat applications every five to seven days.
