Nano-particles derived from Chaetomium lucknowense proved to be antagonized Pyricularia oryzae causing rice blast disease var. RD57. Result showed that nano-ECL, nano- MCL and nano-HCL expressed antifungal activities against P. oryzae (rice blast disease) at the ED50 values were 82, 114, 181ppm, respectively. In pot experiment, the nano-CL gave significantly better to control rice blast than the chemical fungicide (Tricyclazole) in rice var. RD57. Rice blast disease showed that nano-CL gave the highest reduction of 54 %, when compared to the chemical fungicide that the disease decreased 29.26 %. Application of nano- CL gave the highest plant strands of 87.62 cm when compared to Tricyclazole (74.91 cm). Nano-particles from C. lucknowense is being developed to be nano-elicitors for plant immunity.
