ON THE LONGEVITY OF BACTERIUM ORYZAE (U. ET I.) NAKATA UNDER SOME CONDITIONS
FORT DETRICK FREDERICK MD
It was determined that bacteria were viable for 6 months with rice husk as nutrient and 4 months with rice husk powder as medium for the blight bacteria. Furthermore, it was seen that the increase in bacterial growth in the organic material occurred 2 or 3 days after that of the potato broth. After one month of being unattended, the existence of bacteria on damaged leaves was detected and was especially concentrated on those stored indoors. Next, the existence of bacteria was detected in the water, when damaged leaves were kept under wet-land conditions and detected even on damaged unhulled rice. It appeared that around August, the bacteria began decreasing after two days under dry condition indoors. During October, the bacteria were detected beyond 15 days under moist conditions indoors. However, it is thought that after 10 days they rapidly decreased.
