The present investigation was conducted at research plot of the Department of Plant Protection, am Higginbottom University of Agriculture, Technology and Sciences, Naini, Prayagraj, 211007, Uttar Pradesh, India. The observations recorded at successive stages of plant growth were statistically analyzed for interpretation of results. The effect of seed rates on incidence of damping-off was studied at three seed rates and found that the incidence of damping-off increased progressively with increase in the seed rates but dry neem leaves checked the decrease in disease incidence. The effect of different treatments on incidence of damping-off of seedlings was studied. Of these, soil application of Dry Neem Leaves showed better results in managing damping-off both in field.
