Abstract

Though an effective disease management starts with cultural, mechanical and physical methods but practically the chemicals and use of biocontrol agents are important to reduce the outbreak of diseases. The efficacy of new fungicides at different concentrations pave the way for new recommendations with the replacement of old chemicals. To know the efficacy of any fungicide, there is need to test chemicals under laboratory conditions which provide primary information regarding efficacy of fungicides against pathogen within a shortest period of time. An experiment was conducted to evaluate the efficacy of fungicides and bioagents against Phoma sp., causing leaf spot in pigeonpea at Department of Plant Pathology, UAS Raichur. Among the bio-agents tested, T. hamatum (NAIMCC-F-04088) was found to be more effective and statistically significant over other bio-control agents in inhibiting the test fungus. Among, all the tested non-systemic, systemic and combi fungicides, mancozeb, propineb, he

Conclusion

From the present study it was concluded that, Among the bio-agents tested, T. hamatum (NAIMCC-F-04088) was found to be more effective and statistically significant over other bio-control agents in inhibiting the fungu. Among all the tested non-systemic fungicides, systemic and combi fungicides, Mancozeb 75 % WP and Propineb 70 % WP, Hexaconazole 5 % EC and Propiconazole 25 % EC and all the tested combi fungicides were effective with 100 per cent inhibition at all the concentrations tested, respectively.
