| Sumario: | Canker have been found in field plantings of parica examined in Dom Eliseu county, Para State,Brazil. Several fungal species were associated with the field canker, most notably Lasiodiplodia theobromaeand Pestalotiopsis sp. Isolated cultures of these fungi together with other often associated fungi (includingFusarium oxysporum, Alternaria, basidiomycetes) were tested for pathogenicity on young parica plants, withapproximately one meter height. Only L. theobromae produced canker under the conditions tested when discsof culture were applied using wound inoculation techniques and high humidity, which closely mimicked the fieldsymptoms. Pestalotiopsis sp. proved much less damaging compared to L. theobromae. The acknowledgment ofL. theobromae as the causal agent of parica canker came after the reisolations of the fungus from symptomatictissue of inoculated plants, concluding the verification of Koch´s Postulates. This is the first report of thispathogen in paricá. |
