Abstract
Damages caused by Fusarium solani and Rhizoctonia solani, causal agents of root rots, reduce significantly bean seedling emergence, specially in irrigated agricultural systems. There are evidences that rhizobacteria and plant extracts can control soilborne plant pathogens helping seedling emergence. The objective this study was develop an alternative technique to control bean root rot in irrigated cultivation using one strain of Bacillus subtilis and extract of lemon grass (Cymbopogon citratus). B. subtilis, isolated from the rhizosphere of healthy bean plants, and C. citratus extract were assayed in a natural infested area in Guaira, Sao Paulo State, Brazil. Soil and seed treatments in different combinations were investigated under tillage (T) and no tillage (NT) cropping systems. The parameters evaluated were seedling emergence, disease severity, and grain production. The results showed significant differences between the cropping systems. Effectiveness of the rhizobacterium B. subtilis in the controlling of soilborne plant pathogens was observed by reduction of disease incidence (37.6%) e severity (15.0%) with increase of seed emergence (17.1%), and in grain production (17.5%), with the best results for no tillage.
