Mass Multiplication and Shelf Life Studies of Pseudomonas fluoresceins against Pigeonpea Wilt

摘要

Among various solid substrates tested for mass multiplication of potential antagonist Pseudomonas fluorescein isolate CPF_4, farm yard manure supported maximum growth followed by gobar gas slurry. The shelf life period was high in talc based formulation when it was stored at refrigerator temperature (4°C). The efficacy of potential biocontrol agent (CPFJ and compatible fungicide (carbendazim) was tested in pot culture against wilt ofredgram. The results revealed that treatment T_6 (soil applicationwith potential biocontrol agent + soil drenching with fungicide) was superior in reducing per cent disease incidence and increasing plant growth parameters like root length, shoot length, dry weight of shoot and root when compared to other treatments.
