Seleksi Bakteri Antagonis Asal Rizosfer Tanaman Cabai (Capsicum sp) untuk Menekan Penyakit Layu Fusarium secara in vitro

Chili Plants (Capsicum sp) is one commodity that has high economic value susceptible to wilt disease caused by fungus F.o f.sp capsici. The aim of this research is to obtain fungus Fo f cap capsici cause wilt disease in chilli plant that is sick, to obtain isolate of antagonistic bacteria that able to inhibit fungus development fosp capsici and to know effectiveness of antagonistic bacteria in inhibiting fungus development fosp capsici cause of wilting on pepper plant. This research was conducted in Biology Laboratory of FMIPA UNM. This research used Completely Randomized Design (RAL) with 9 treatments and 3 replications. Analyze data using ANOVA and Duncan test. Based on the morphological character of macroscopic and microscopic fungi isolated from the sick Lombok plant is Fusarium oxysporum f.sp capsici. The best antagonistic bacterial isolates inhibited the growth of F.o f.sp capsici in vitro Bacillus sp 81.0%
