Influence of Bacillus polymyxa on the growth and development of Fusarium oxysporum f. sp. tulipae

Abstract

Antagonistic effect of Bacillus polymyxa, strain S13, toward Fusarium oxysporum f. sp. tulipae was evaluated iii vitro and in vivo. The growth of the pathogen was greatly inhibited in dual cultures with Bacillus polymyxa on potato dextrose agar. Suspension of B. polymyxa and its filtrate substantially inhibited spore germination and development of Fusarium oxysporuum f. sp. tulipae on tulip bulbs.
