The objective of the research was to evaluate the effectiveness of Allium sativum extracts and Lippia alba on pathogens and the physiological quality of Chorisia glaziovii seeds. The treatments consisted of Allium sativum extracts and Lippia alba at 0, 25, 50, 75 and 100%, and fungicide captan (240 g 100 kg-1 seeds) as the positive control. For the seed sanity, it was adopted the Blotter test method and the physiological quality was determined by germination and seed vigor. The design was completely randomized in a factorial scheme (2 x 5) +1 (plant extracts x concentrations + fungicide) with four replications. It was observed the occurrence of Aspergillus flavus, Aspergillus niger, Aspergillus sp., Botrytis sp., Cladosporium sp., Curvularia lunata, Nigrospora sp., Pestalotia sp., Periconia sp. and Rhizopus stolonifer on seeds. The Lippia alba extract at 100% was effective in inhibiting pathogens. The increase in the concentration of A. sativum extract reduced to the frst count, and Lippia alba extract caused increase of germinated seeds.
