SCREENING OF RHIZOBACTERIA FROM ONION RHIZOSPHERE CAN INDUCE SYSTEMIC RESISTANCE TO BACTERIAL LEAF BLIGHT DISEASE ON ONION PLANTS
Abstract
In modern cultivation processes indiscriminate use of pesticides and fertilizers, has led to substantial
pollution of soil, air and water. So, there is an urgent need to solve the problem. Rhizobacteria are bacteria that
colonize plant roots, and these bacteria are known to stimulate growth and thereby reduce incidence of plant
disease by direct and indirect mechanisms. A total of 136 rhizobacteria isolates were isolated from different
rhizosphere soils in central areas of production of onions in Indonesia. These isolates were screened for their
capability to enhance growth and protect onions against bacterial leaf blight disease-caused by Xanthomonas
axonopodis pv.allii. The results showed that ten isolates can enhance growth and protect onions against bacterial
leaf blight diseases. Five isolates were isolated from West Sumatra, four isolates from Java and one isolated from
North Sumatra. All isolates produced indol-3-acetic acid with different concentrations. Molecular identification
of ten isolates belong to Bacillus sp, Pseudomonas sp, Stenotrophomonas sp and Serratia sp.
