A baiting technique was developed to estimate the population of Drechslera nodulosa (Berk. and Curt.) Subram. and Jain in soil by using susceptible ragi (Eleusine coracana Gaertn.) culms. The number of lesions developed on baited culms were reduced with the reduction in concentration of D. nodulosa propagules in both sterilized and unsterilized soils. Based on this a standard correlation (concentration vs infection probability) was established which was found to be quite efficient method to estimate the population in soil and to bait even when the inoculum level was 4 propagules per g of soil. © 1980 Martinus Nijhoff Publishers b.v
