Abstract

Root rot is one of the most serious disease in Tangerine which caused by Pythium spp. This study tested efficacy of Ch. brasiliense to control Pythium sp. by bi – culture, crude extracts and nano particles testing from Ch. brasiliense to control Pythium sp., in vitro. The results from the bi – culture testing, Ch. brasiliense inhibited mycelium growth and sporangia production by 42.50% and 48.41%, respectively. In crude extracts from Ch. brasiliense gave ED50 values of 30.15, 58.71 and 37.25 ppm for the hexane, EtOAc and MeOH, respectively. The efficacy of nano particles against Pythium sp. with the ED50 values of 2.69, 3.00 and 3.96 ppm for the hexane, EtOAc and MeOH, respectively.
