Abstract : Six hosts (mango, apple, pear, grapevine, potato and carrot) were inoculated with pairs of pathogenic fungi either simultaneously or one before the other. Six different associations were observed: (1) no interaction (as on apple between Alternaria alternata and Botryosphaeria obtusa); (2) slight predominance (of Botryodiplodia theobromae over Aspergillus niger on mango); (3) strong dominance (of A. niger over Geotrichum candidum on pear); (4) aggravation and synergism (between A. niger and B. theobromae on grape); (5) one predominant but aggravated by the other (Sclerotium rolfsii by Fusarium oxysporum on potato); and (6) aggravation in mixed infections but predominance of the earlier settler (between Rhizopus oryzae and S. rolfsii on carrot).
