One of biological controls which can be used is antagonistic endophyte fungi from medical plants, i.e Artemisia annua L. Endophytic fungi can increase plant resistance. This research aimed to obtain fungi from A. annua leaves and evaluate its potential in inhibiting R. solani in vitro and in vivo. The study was conducted using a Completely Randomized Design (CRD) with 1 factor and 3 replications. A total of 11 fungi was successfully isolated, then a pathogenicity test showed that 5 fungi did not cause necrosis, namely Penicillium sp., Phoma sp., Cladosporium sp., Aureobasidium sp. 1, and Aureobasidium sp. 2. The result showed that Phoma sp. had the best inhibitory ability in vitro by 66.7%. Application of Phoma sp. gave the best inhibition on the lesion length by 11.33 mm and infection rate by 1.85 day units-1 with the effectiveness of disease control (EDC) 5.95% in vivo. The inhibition of rice sheath b...
