UJI EFEKTIVITAS BAKTERI ANTAGONIS Pseudomonas flourescens DAN P. putida UNTUK MENGENDALIKAN P. solanacearum PENYEBAB PENYAKIT LAYU PADA TANAMAN MURBEI
Abstract: Pseudomonas
solanacearum is a bacterial agent causing wilt disease on mulberry species and
other woody plant in Indonesian. Biological control employing the antagonist
bacteria such as P. fluorescens and P. Putida is a potential method. The aim of
the research was to know the effectiveness of P. fluorescens and P. putida to
suppress wilt diseases caused by P. solanacearum. The diseases control test
with antagonist bacteria was conducted by immersion of root of seedlings in P.
fluorescens and P. putida suspensions before planted in a growth medium
inoculated by P. solanacearum with the all concentrations were 108 CFU/ml. The
following parameters were observed: numbers of leaves, fresh and dry weights of
leaves and severity of disease. The results of the effectiveness test showed
that antagonist bacteria in the form of mixing of P. fluorescens and P. putida
was the best, because they were capable to suppress wilt disease caused by P.
solanacearum and increased productivity of mulberry leaves.
