Biological Pest Control

open access: yes, 2021
Organic farmers can control pests by providing habitat to support beneficial organisms, using trap crops, releasing biocontrol agents or applying biopesticides (pesticides made from natural sources, such as microorganisms, plants, animal tissue or minerals). Biocontrol (biological control) agents are living organisms that are introduced or supported by
