Abstract:

Soybean (Glycine max) is a miracle crop due to its extraordinary qualities apart from known for rich source of vegetable protein and oil. Over the years, its production is stagnant or declining owing to climate change and also due to ever changing pathogenic behaviour of Macrophomina phaseolina. The present investigation was undertaken to utilize the dominant resident mycoflora of crop that are capable of adjusting to changing environment apart from its ability to combat the menace of its co-partner (pathogenic group) evolving with them. Dominant rhizosphere fungi viz. Trichoderma asperellum and its ten isolates were isolated through dilution plate technique. Efficacy of Trichoderma asperellum isolates against M. phaseolina was established through dual culture and poison food technique. Under in-vivo conditions, their impact on physiological parameters and disease suppression ability has also been established. The isolates with higher mycelia growth suppressing ability under dual culture technique had not found inhibitory towards the test pathogen under poison food technique. Similarly, T. asperellum isolates tested under in-vitro showed their varying potential against pathogenic fungi under in-vivo conditions.
