Organic fungicides

by M. Arjoca,

The fungi are another problem which can occur in garden. They proliferate in wet climates and many times are helped by insects to infect the plants. There are many types of fungi, some of them being specific to certain plants. Generally the plants are resistant to pests, inclusive fungi, but if the infestation is too strong, their strength becomes weaker and they can die.

When you work with plants you must know some prevention and pest control methods. Here are some organic fungicide recipes which can be used when it’s necessary.
