Anti-mycotic potential of Trichoderma spp. and leaf biomass of Azadirachta indica against the charcoal rot pathogen, Macrophomina phaseolina (Tassi) Goid in cowpea
Macrophomina phaseolina (Tassi) Goid is a destructive pathogen of cowpea that causes serious charcoal rot disease with significant yield losses. Antifungal activity of three indigenous Ascomycetes viz., Trichoderma harzianum, T. viride, and T. hamatum, and two Meliaceae members, i.e., Melia azedarach L. and Azadirachta indica L. were assessed against the pathogen. Laboratory screening trials wi...
متن کاملEvaluation of antifungal activity of Meliaceae family against Macrophomina phaseolina
Macrophomina phaseolina (Tassi) Goid is a soil-borne fungal pathogen that causes root rot disease in more than 500 plant species but no registered fungicide is available for its control. The present study was carried out to investigate the antifungal activity of aqueous leaf extracts of Azadirachta indica A. Juss., Melia azedarach L. and Toona ciliata Roxb. (Meliaceae) against M. phaseolina. Aq...
متن کاملEvaluation of bacteria isolated from rice rhizosphere for biological control of charcoal rot of sorghum caused by Macrophomina phaseolina (Tassi) Goid.
A total of 360 bacteria, isolated from the rhizospheres of a system of rice intensification (SRI) fields, were characterized for the production of siderophore, fluorescence, indole acetic acid (IAA), hydrocyanic acid (HCN) and solubilization of phosphorus. Of them, seven most promising isolates (SRI-156, -158, -178, -211, -229, -305 and -360) were screened for their antagonistic potential again...
متن کاملAntagonistic potential of fluorescent pseudomonads and control of charcoal rot of chickpea caused by Macrophomina phaseolina.
The effectiveness of plant growth promoting rhizobacteria especially Pseudomonas fluorescens isolates were tested against charcoal rot of chickpea both in green house as well as in field conditions. Most of the isolates reduced charcoal rot disease and promoted plant growth in green house. A marked increase in shoot and root length was observed in P. fluorescens treated plants. Among all the P....
متن کاملAntagonistic effect of fluorescent pseudomonads against Macrophomina phaseolina that causes charcoal rot of groundnut.
Maximum colony growth inhibition was observed due to Pseudomonas PS2 (74%) as compared to PS1 (71%) on trypticase soy agar (TSM) plates after 5 days of incubation. Light and scanning electron microscopic examination showed hyphal coiling, vacuolation, coagulation and granulation of cytoplasm resulting in lysis of hyphae of M. phaseolina by pseudomonads. Cell free culture filtrates of strains PS...
