Antagonistic 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...

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 کاملScreening of Pseudomonas fluorescens isolates for biological control of Macrophomina phaseolina root-rot of safflower
The aim of this study was to assess the potential bacterial antagonists to control Macrophomina phaseolina root-rot of safflower by using screening methods. In total, 38 fluorescent pseudomonads isolated from rhizosphere soil of healthy safflower plants were collected from major safflower growing areas, 13 were initially selected based on dual culture technique on potato dextrose agar media. Fu...
متن کاملBIOPESTICIDAL ACTIVITY OF Calotropis procera L. AGAINST Macrophomina phaseolina
BACKGROUND Mungbean [Vigna radiata (L.) Wilczek] is an important pulse crop globally. This imperative crop is severely affected by charcoal rot disease caused by Macrophomina phaseolina (Tassi) Goid. In the present study, the leaves of Calotropis procera L. were tested for their antifungal potential against M. phaseolina. MATERIALS AND METHODS Various concentrations i.e. 1%, 2.5%, 4%, 5.5% an...
