It is commonly known as Safed musli viz. a traditional medicinal plant belongs to family Liliaceae. Chlorophytum borivilianum (Liliaceae) is listed as endangered species valued for its fasciculate storage roots.

Tiny, pin-head, round, reddish-brown lesions first appeared on the leaves as longitudinal streaks along the midrib veins and at the margins of the diseased leaves. When leaves are infected, they dry out too soon and the plant is unable to produce healthy fingers, which is why they are used medicinally. Following the start of the rainy season, this disease manifests in August and September. Among the different diseases of Chlorophytum borivilianum, leaf blight caused by Colletotrichum capsici is very severe viz. responsible for 30 per cent yield losses. Keeping this in view, the present investigation was under taken to study the DSI at the field of Dahegaon Taluka Vaijapur Dist., Aurangabad.
