Popis:	Summary A new antagonist/pathogen combination is reported, with Bacillus pumilus showing strong antagonistic activity against Penicillium digitatum. B. pumilus (1.6 × 1010 to 1.6 × 1012*cfu ml-1) gave significant control of P. digitatum infection in Valencia orange, which was as effective as imazalil (500 μg ml-1) and was significantly better than benomyl treatment (500 μg ml-1). When lower concentrations of B. pumilus (1.9 × 107 to 1.9 × 109 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 × 104 and 6.5 × 105 spores ml-5). Concentrations of both the pathogen and the antagonist affected the biocontrol effect.
