Alternaria alternata as a mycoparasite of Rhizopus nigricans

Abstract

Interaction between <i>Alternaria alternata</i> and <i>Rhizopus nigricans</i> was studied in vitro in dual cultures to examine their antagonistic behaviour. <i>A. alternata</i> parasitised <i>R. nigricans</i> by direct penetration of hyphae, sporangiophores and sporangia. <i>R. nigricans</i> is described here as a new host record for the mycoparasite <i>A. alternata</i>.
