AbstractIn this study the test combination activity between Bacillus subtilis and watery cinnamomum extract is concentration different in the growth inhibition of the Rhizoctonia solani caused the root rot disease of capsicumplant and compared if the uses bacteria and extract both alone . It showed the results of laboratory the combination treatments between Bacillussubtilis and watery extract of cinnamomum the concentration (10 , 20 ,30) mg / ml has the highest percentage in the inhibition of the growth Rhizoctonia solani which has( 76.66 , 82.21 , 89.71 ) % respectively after three and six days compared to the control treatment which has to the percentage of inhibition of the pathogen fungus 0.00% . As uses of bacteria treatment alone has led to the growth inhibition of the pathogenic fungus colony in both time periods and a difference significant for the control which has the percentage of the fungus inhibition 74.71% and 64.71% after three days and six days respectively . Either uses of cinnamomum extract alone of the concentration of ( 20, 30) mg / ml has a highly significant difference compared to the treatment control as percentage of pathogenic fungus inhibition in both the two time periods ( 40.55 , 54,71) % respectively after three days and and ( 13.88 , 46.10 ) % respectively after six days . The uses of cinnamomum extract treatment alone concentration of 10 mg / ml the percentage of fungus inhibition 31.91% after three days and asignificant difference for the control treatment , but treatment is encouraging for the growth of the pathogenic fungus colony Rhizoctonia solani during the second time period as the percentage of inhibition fungus 0.00% after six days without any significant differences from the control treatment . We conclude from the results of this study the use of Bacillus subtilis and watery cinnamomum extract as combination considered method is very important in achieving the best results in control on the Rhizoctonia solani fungus causes the root rot capsicum .
