Y.  aPostharvest biological control of penicillium digitatum decay on citrus fruit by Bacillus pumilus.h[electronic resource]  c1992  aA new antagonist/pathogen combination is reported, with Bacillus pumilus showing strong antagonistic activity against Penicillium digitatum. B. pumilus (1.6 x 10^10 to 1.6 x 10^12 cfu ml-1) gave significant control of P. digitatum infection in Valencia orange, which was as effective as imazalil (500 mg ml-1) and was significantly better than benomyl treatment (500 mg ml-1). When lower concentrations of B. pumilus (1.9 x 10^7 to 1.9 x 10^9 cfu ml-1) were tested on Washington Navel orange and Lisbon lemon fruit, the antagonist caused significant control of P. digitatum infection at two inoculum levels (6.5 x 10^4 and 6.5 x 10^5 spores ml-1). Concentrations of both pathogen and the antagonist affected the biocontrol effect.  aCitrus  aAntagonismo  aBactéria  aPós-Colheita1 aWILD, B. L.1 aMORRIS, S.
