| Abstract | ||
| The bacteria Pseudomonas fluorescens apply to control damping off disease , caused by Rhizoctonia solani Kuhn on tomato seedling. The result showed that Pseudomonas fluorescens had antagonistic activity during inhibition of Rhizoctonia solani were demonstrated by using the dual culture method (%48,15 ) , the increase in concentration of bacteria in soil or seed coating very effect to reduce death seeds or infected seedling by Rhizoctonia solani. The result showed also significantly effect when we used seed coating bacteria to protect from pathogen (4 seeds) death & reduce in infected seedling (10 seedlings) compared with addition the bacteria to soil (22 seeds) & (29 seedlings). The result demonstrate successed biocontrol depend on method & addition usage of biocontrol agent. These results suggest that the P. fluorescens have an excellent potential to be used as biocontrol agents of R. solani in tomato in greenhouse conditions. | ||
