Abstract

Pearl Millet (Pennisetum glaucum (L.) R.Br.), is a staple food and fodder crop of semiarid- tropics grown under erratic climatic conditions. It is considered to be one of the best drought tolerant cereal crops of the world. The crop is a component of dry land farming system and is grown in regions where the fertility of the soil is low. Pearl millet production is reduced considerably due to downy mildew disease caused by Sclerospora graminicola. Though there are many methods like cultural practices, use of resistant cultivars 'and fungicides, each one has its own limitations. Hence, in the present study, a eco-friendly biotechnological technique Systemic Acquired Resistance that complements resistance breeding and pesticide use was developed for managing downy mildew disease in pearl millet by seed treatment. The mechanism of induction of resistance is through biological protection of plant through activation of plant's own defense machinery by triggering metabolic activity and not based on elimination of the pathogen. Thus the target of modification -is the plant rather than the pathogen.
