National Symposium on Strategic Issues in Plant Pathological Research held at Department of Plant Pathology, CSK HP Krishi Vishvavidayalaya, Palampur on November 24–25, 2011
Organic formulations were tested for their efficacy in the management of seed borne microflora of pulses such as mash, lentil and soybean. A total of 38, 11 and 6 fungal pathogens and 4 bacterial pathogens were isolated from soybean, mash and lentil seeds respectively. Associated microflora was tested by blotter method and a significant reduction in frequency of associated microflora and increase in germination was recorded in eight treatments as compare to control. Among these treatments, seeds of soybean, mash and lentil treated with jeevamrit, beejamrit and panchgavya showed higher percent germination 96, 90 and 60% as compare to control 54% respectively. The number and frequency of microflora decreased to significant level by treatment with organic formulations. Organic formulations viz, panchgavya, matka khad and vermiwash lead to complete reduction in percent frequency of Aspergillus sp, Penicillium sp, Rhizopus sp and Fusarium sp. in case of mash followed by lentil and soybean in which panchgavya, biosol and matka khad resulted in reduction of Fusarium sp and Rhizoctonia sp as compare to control. Panchgavya, biosol and vermiwash exhibited complete reduction in per cent frequency of bacterial pathogens as compare to control (6- 20%). Seeds of maize treated with panchgavya also showed complete reduction of Aspergillus sp and Fusarium sp.
