Method:

When apples rot, the diseased spots are scraped off first, and the solution is diluted 30-40 times with EM bacteria (special type for agricultural planting) (pay attention to water 29-39 kg, EM 1 kg), then a proper amount of new soil or fully decomposed farm manure is added into the diluted solution to form bacterial mud, which is smeared to cover the diseased spots with a thickness of 2 cm, and finally wrapped with plastic strips.
