Abstract
The biocontrol agent Serratia plymuthica A21-4 was selected and proved as an excellent inhibitor of Phytophthora blight of pepper through in vitro and in vivo experiments in previous studies. To enhance the colonizing density of S. plymuthica A21-4 on plant root and rhizosphere soil, some soil conditions might effect on the colonization of the bacteria were examined. The results obtained from the study indicated that the soils containing more sand were favorable to root colonization of S. plymuthica A21-4. Organic amendment such as 3% maize straw(w/w) was helpful to colonize the bacteria in root and soil. The soil temperature about $20^{\circ}C$, water content around 40%, and soil pH near to neutral or slightly acidic, were optimum condition for the colonization of S. plymuthica A21-4 in the rhizosphere soil and roots of pepper. In addition, existence of indigenous biotic entities was beneficial to the colonization of S. plymuthica A21-4.
