Abstract

An experiment was carried out at the Instructional Farm of Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment was laid out in Randomized Block Design (RBD) with four treatments and six replications. To estimate the yield loss under 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. The results revealed that both the years’ kharif 2017-18, organically protected plots inoculated with A. alternata recorded significantly the highest seed yield of mungbean is 9.11 and 9.18 Qha-1 . The data on per cent decrease yield in unprotected plots over organically protected plots during 2017 and 2018 indicated that under inoculations of A. alternata when the crop was left unprotected, the yield was decreased to 45.38 and 42.29 per cent and the case of naturally infected powdery mildew unprotected plots, the seed yield of mungbean was decreased t

Conclusion

Looking to the importance of the disease and intensification of cultivation of major mungbean growing areas of Rajasthan, a need was felt to develop its effective and eco-friendly management strategy are needed. The organic based finding for management of leaf spot and powdery mildew are helpful to design IDM strategies based on organic inputs which can be applied at farmer’s field.
