Estimation and Evaluation of Rhizosphere Mycoflora and Fluorescent Pseudomonads against Rhizoctonia solani under in vitro Condition

The purpose of this study was to evaluate the in vitro evaluation of mycoflora rhizosphere and fluorescent pseudomonads against Rhizoctonia solani. Tomato is one of the world’s most commonly eaten vegetables (Solanum lycopersicum L.). Several soil-borne fungal pathogens invade tomato crops, including Rhizoctonia solani, the most important soil-borne pathogen, causing symptoms of damping off, crown rot, and root rot. The population of rhizosphere mycoflora and fluorescent pseudomonads was estimated from the soil samples collected from diseased, stable and luxuriously growing weed plants as colony forming units (cfu) on different culture media to provide bio-efficacy against casual agents and were tested for their antagonistic potential against R. Under in vitro scenario, solani. The antagonistic behaviour of both the fluorescence and mycoflora The research pathogen R was tested against pseudomonads isolated from rhizospheric soils. Solani by following the technique of dual culture. For samples collected from weed plants followed by healthy tomato plants, the significantly higher mean cfu count of mycoflora (27.70) and fluorescent pseudomonads (40.75) was observed among the sources of rhizosphere soil collected. Among the mycoflora, the possible antagonist was found to be the isolate M10 and was known as Trichoderma viride, while Pseudomonas fluorescens was known as the successful pseudomonad isolate P1.
