Mancozeb exhibited excellent control of blast disease (Pyricularia grisea), while bavistin and captan at par (1.0) in nursery when seeds of rice var. K-448 were treated. Moreover, on transplanted crop, three sprays of bavistin (0.1%) and mancozeb (0.1%) cum -seed treatments proved to be the more effective and were able to bring down the incidence of sheath blight (Rhizoctonia solani) leaf and neck blast with corresponding increase in the yield. The neck blast did not appear in seed treatment -cum-sprays of tested fungicides. Similarly, the sheath blight disease was also reduce but maximum control was found when spray of bavistin (0.1%) followed.
