    Durian are the economically fruit trees in Thailand. The important problem of durian is root rot disease caused by Phytophthora palmivora. This study was used Chaetomium elatum to control the P. palmivora causing root rot disease of durian by dual culture method, crude extract test and nano particles test derived from Ch. elatum. Dual-culture test showed that Ch. elatum gave efficiency to inhibit of spore and colony growth of P. palmivora which were 46.13 and 38.89%, respectively. Testing efficacy of crude extract from Ch. elatum to control P. palmivora found that crude ethyl acetate from Ch. elatum gave significantly highest against pathogen of P. palmivora at the concentration of 1000 ppm which the ED <inf>50</inf> of 175.31 ppm. Nano particles testing, nano particles of crude hexane, ethyl acetate and methanol from Ch. elatum showed the ED <inf>50</inf> values of 3.49, 3.47 and 3.41 ppm.
