mycoplasma-like organisms cause diseases in rice. Disorders or abnormalities may
also cause by abiotic factors such as low or high temperature beyond the limits
for normal growth of rice, deficiency or excess of nutrients in the soil and
water, pH and other soil conditions which affect the availability and uptake of
nutrients, toxic substances such as H2S produced in soil, water stress and
reduced light. In broad sense such disorders and abnormalities refer as
physiological diseases. However, here we will cover only the common diseases of
rice those cause by pathogen. Before attempting diagnosis of rice diseases it is
