Uji Efektivitas Agen Hayati Dari Rizosfer dan Filosfer Tanaman Solanaceae untuk Mengendalikan Penyakit Antraknosa pada Tanaman Cabai Rawit (Capsicum frutescens L.)

Abstract

Effectiveness of biological agents from Solanaceae plants rhizosphere and
filosphere to control Antrachnose disease in Chili Pepper Plants
(Capsicum frutescens L.).

The disease antrachnose caused by the fungus Colletotrichum truncatum can
attack the chili fruit at any stage, but it will not attack the leaves or stems. The use of
biological agents from the rhizosphere and filosphere is a viable alternative to control
the anthracnose disease. Biological agents work selectively and better for the
ecosystem. The goal of this research is to identify the effectivenes of biological agents
from rhizospheres and filospheres solanaceae plant to control C. truncatum that causes
antrachnose disease in Chili Pepper Plants (Capsicum frutescens L.). This research
takes place in vitro and the field this research shows that TmFr4 and TrRr7 treatment
can inhibit the growth of C. truncatum in vitro with a high percentage of inhibition
90,58 % and 91,23 %. The TrRr7 bacterial isolate can inhibit the anthracnose disease
from 95,23% to 64,23 % and able to reduce the intensity from 66,59 % tob 39,06 %
while TmFr4 fungal isolates can inhibit the desiase from 95,23 % to 68,81 % and
reduce its intensity from 66,59 % to 47,03 % base on the field test. Further study is
needed to analyze the stability of TmFr4 fungal isolate and TrRr7 bacterial isolate
biological control of C. truncatum in the field.
