Bio-fungicides are fungicides that are from non-inorganic sources like plant origin or animal origin or maybe organisms. Many hyperparasites like fungi and bacteria are used as organic or bio fungicides. Bacteria and fungi of certain families are known to kill plant pathogenic fungi on many crops as well as in the soil. These are also called biological agents to control fungal diseases. These bacteria or fungi may directly kill the pathogenic disease-causing fungi, struggle for the food and space to live, and may release toxins to kill the pathogenic fungi or bacteria..
