The main mechanisms attributed for biocontrol include: synthesis of secondary metabolites, such
as 2,4 - diacetylphloroglucinol (2,4 - DAPG), hydrogen cyanide (HCN), pyoluteorin, pyrrolnitrin, phenazines, cyclic lipopeptides (CLP) and siderophores (6); production of phytohormones, such
as auxins, cytokinins and
gibberellins;
as well
as nutrient solubilization traits (nitrogen, phosphorous, iron), which directly favors plant growth and health (7).
