In vitro study of effectiveness of plant extracts against rhizoctonia solani causing sheath blight disease on rice (Oryza sativa L.) / Nur Maryam Mohamed
Rice is an important cereal crop affected by various fungal, bacterial and virus diseases. Sheath blight disease caused by Rhizoctonia solani is one of the destructive disease under favourable weather conditions in rice growing areas that ultimately causes high yield losses. The initial symptoms are...
