Title: Colonization of Antagonistic Bacteria Against Botrytis cinerea on Tomato
Abstract: Bacillus licheniformis (W10) and Paenibacillus polymyxa (W3, Y2111), antagonistic against Botrytis cinerea, were induced to be rifampicinresistant and used for monitoring their colonization on leaves and fruits of tomato plant. Experiments showed that the introduced antagonistic bacteria could colonize on tomato plant for 10-15 d at higher concentration (107-109cfu/ml). In comparison with inoculation of antagonistic bacteria only, preinoculation of B. cinerea had a negative effect on colonization of the antagonists, which indicated that the antagonistic bacteria was better in prevention than curation for grey mould. Moreover, higher temperature (25-35℃), higher relative humidity (RH 95%-100%) and 12 h alternation of light and dark were favorable to the colonization of the antagonistic bacteria.
