Foliar Borne Diseases of Tropical Tuber Crops and Its Management

Abstract

One of the major constraints that affect the yield of plants is biotic stress. Among these, fungi are the most common parasite causing plant diseases that occur primarily on leaves including stem, fruits & roots. Symptoms of fungal foliar diseases in tuber crops include stolon, wilting and chorosis. Tuber crops become infected through diseased stolons and show darkened diseased area on the skin. Starchy roots and tuber crops play a pivotal role in the human diet. Tubers are enlarged structures used as storage organs for nutrients in some plants and also for plants perennation to provide energy and nutrients for regrowth during the next growing season. General management of foliar disease in tuber crops includes using of biofungicides to medium before pouring it into the soil.
