Abstract:

Fruit rot of brinjal caused by Alternaria alternata is an important disease of eggplant inflicting heavy losses. The present investigation was carried out to test the efficacy of fungicides, botanicals and bio-agents in vitro. Among fungicides tested, tebuconazole, difenconazole showed 100 per cent mycelial inhibition of Alternaria alternata. The results of botanicles tested in vitro revealed that onion and garlic bulb extract showed highest inhibition of mycelial growth both @ 5 and 10 per cent concentration. The results of dual culture technique revealed that fungal bio agents were better than bacterial bio-agents in inhibiting the growth of Alternaria alternata. All the strains of Trichoderma harzianum were found antagonistic to A. alternata, however stronger antagonism was noticed in case of T. harzianum-21.
