Since both ‘ear cockle’ and ‘tundu disease’ occur on wheat frequently in association, the bacteria are carried along with the galls developed due to ear cockle disease caused by the nematode. Tundu disease is also called as yellow ear rot diseases. The first visual evidence of Soil-borne wheat mosaic virus (SBWMV) infection in a growing season usually occurs in the spring, after the crop begins to green up. Wheat is subject to more diseases than other grains, and, in some seasons, especially in wet ones, heavier losses are sustained from those diseases than are in other cereal crops. Loose smut causes damage by destroying the kernels of the infected plants, also by lowering the quality of the seed of the non-infected plants upon harvest.
