Isolasi dan Uji Antifungi Bakteri Endofit Tanaman Padi (Oryza sativa L.) dan Jagung (Zea mays L.) terhadap Rhizoctonia solani

Abstract

Isolation and antifungal essay of endophytic bacteria from paddy and corn has been conducted. There were eight and five endophitic bacterial isolates from corn and paddy, respectively. All corn isolates and three paddy isolates showed to inhibit R. solani growth in vitro. AJ02 of corn has showed maximum inhibition to fungal growth with the inhibition zone of 21 mm. Meanwhile, the BJ01 showed minimum inhibition zone, with inhibition by 14,5 mm. The DP01 of paddy showed the maximum inhibition zone 18 mm. BP01 showed the minimum inhibition zone, 13,5 mm. AJ02, DJ01 of corn and AP01, DP01 of paddy were used for the study since all four showed maximum inhibition to fungal growth. Corn isolates AJ02 and DJ01 were able to decrease R. solani attack by 25% and 22% respectively, while paddy isolates AP01 and DP01 were able to decrease R. solani attack of 22% and 27% respectively.
