The Embrapa Soya Collection of Microorganisms of Interest for Agriculture (CMES) has the main objective of preserving pathogens (fungi, viruses and bacteria) of importance for soybean cultivation and microorganisms with potential for biological control of these phytopathogens. The collection also contains pathogens associated with wheat, sunflower and some weeds. Weed pathogens may have the potential to control these plants.
