Abstract:
An experiment was carried out at the Instructional Farm of Rajasthan College of Agriculture, MPUAT, Udaipur during kharif 2017 and 2018. The experiment was laid out in Randomized Block Design (RBD) with four treatments and six replications. To estimate the disease severity generated by inoculation of most virulent A. alternata isolate MAa- 2 cultured in laboratory with 1×103 conidia ml-1 concentration and in natural conditions of powdery mildew. Pooled analysis for both the years evinced that organically protected plots under inoculations of A. alternata showed a minimum PDI of 17.53 which was followed by organically protected plots of powdery mildew under natural conditions with 20.24 PDI. The unprotected plots under inoculations of A. alternata and powdery mildew in natural conditions depicted 54.67 and 43.48 per cent disease intensity, respectively.
