Postharvest biological control of Penicillium digitatum decay on citrus fruit by Bacillus pumilus.

A new antagonist/pathogen combination is reported, with Bacillus pumilus showing strong antagonistic activity against Penicillium digitatum. B. pumilus (1.6x1010 to 1.6x1012 c.f.u./ml) gave significant control of P. digitatum infection in Valencia orange, which was as effective as imazalil (500 micro g/ml) and was significantly better than benomyl treatment (500 micro g/ml). When lower concn of B. pumilus (1.9x107 to 1.9x109 c.f.u./ml) were tested on Washington Navel orange and Lisbon lemon fruit, the antagonist caused significant control of P. digitatum infection at 2 inoculum levels (6.5x104 and 6.5x105 spores/ml). Concn of both the pathogen and the antagonist affected the biocontrol effect.
