SKRIPSI UJI KONSENTRASI PATOGENITAS JAMUR Beauveria bassiana Vuill TERHADAP KEPINDING TANAH (Scotinohara vermculata Voll) PADA TANAMAN PADI (Oryza sativa, L.)
ABSTRACT
A research its to study the pathological cha
racteristics Beauveria bassiana fungus on Soil bugs at
Rice stand. This research was done in Laboratory of
Supervision and Forecast of plant Pest of the District
Banyumas in Jatilawang. The research was done in
February until July 2001.
The research is factorial experiment (6x2) with
randomize completely design with threen replications. The
first factor is concentration of Beauveria bassiana,
0,102, 104, 106, 108, 1010. The Second factor is stadium Soil
bugs, of nimpha and imago.
Beauveria bassiana have Pathological characteristic
to Soil bugs. Concentration of Beuveria bassiana
influences mortality of Soil bug. Increasing
concentration of Beauveria bassiana may increase
mortality rate of Soil bug, Pathogenic effect of
Beauveria bassiana is stranger on young bugs. Increasing
Beauveria bassiana concentration on bugs stadia has
regular effect on mortality rate. The effect of Beauveria
bassiana to the rice stand is inderectly as a result of
the mortality.
