Abstract:
The present investigation carried out against stem and root rot of sesame incited by Macrophomina phaseolina. Eight Contact and translocate fungicides like carbendazim, carbxin + thiram, carbendazim + mancozeb, propiconazole, hexaconazole, thiophanate methyl, propineb and tebuconazole were tested in laboratory conditions and found that the carbendazim + mancozeb and carbendazim were inhibited mycelial growth completely (100, 100 and 100%) at all the concentration i.e. 100, 200 and 300 ppm concentration followed by carboxin + thiram 85.00, 95.17 and 100 per cent at 100, 200 and 300 ppm concentrations, respectively. However, thiophanate methyl and propineb were found less effective to inhibit mycelial growth over control. Eight botanical extracts tested against M. phaseolina under in vitro condition, all botanicals found superiorly significantly over control, in which Garlic clove extract found most superior to inhibit mycelial growth (76.67, 89.33 and 100%) at concentrations 5, 10 and 15% respectively on PDA followed by neem leaf extract (76.30, 81.25 and 85.06%). Mean mycelial growth inhibited (88.67%) with garlic extract followed by neem leaf extract (80.87%) was observed. Aak extract found least effective with minimum mean mycelial growth inhibition (17.85%).
