In the present work, two different types of disease symptoms and two different kinds of pathogenic fungi such as Fusarium sp. (1) which causes Narrow Brown Leaf Spot and Mucor sp. (1) which causes Blight were studied on Oryzasativa L. (That-gyi Saba). In Oryzasativa L. Thatt-lat Saba, Gloeosporiumsp. (1) that caused White Spot, Mucorsp. (2) that caused Blight, Gloeosporiumsp. (2) that caused Brown Spot, Rhizoctonia sp. (1) that caused Leaf Scald , Rhizoctonia sp. (2) that caused Sheath Blight and Fusarium sp. (2) that caused Grain Discoloration, In the case of Oryza sativa var. glutinosa (Kaung-nyin, That-Nge Saba), 4 different types of disease symptoms and 4 different kinds of pathogenic fungi were investigated these include Leaf Stripe caused by Rhizoctonia sp.
