In vitro tolerance of rice pathogen Rhizoctonia solani by orchid mycorrhizal fungi isolated from orchids in BRIS, Setiu Wetlands

Rice (Oryza sativa) is a major staple food that feeds more than half of the human population in the world. However, rice production faces major loss in yield due to rice diseases including Rice Sheath Blight (RSB), which is caused by a soil-borne fungal pathogen, Rhizoctonia solani. Interestingly,...
