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 cereals viz, paddy, maize and wheat. A total of 27, 30 and 5 fungal pathogens and 2 bacterial pathogens isolated from maize, wheat and paddy seeds respectively. Evaluation of formulations for associated microflora by blotter method showed significant variation with respect to reduction in frequency of associated microflora and increase in seed germination in eight treatments as compare to control. Among these treatments, seeds of maize, wheat and paddy treated with panchgavya, vermiwash and biosol showed higher percent germination 96, 95 and 94%, respectively as compare to control (86%). Whereas in maize, jeevamrit and vermiwash provided 94% germination and beejamrit and matka khad increased the germinations to 93% in wheat as compare to control (86%). The number and frequency of microflora decreased to significant level by treatment with organic formulations. All the treatments lead to complete reduction in percent frequency of Aspergillus niger, Penicillium sp, Rhizopus sp and Fusarium sp. in case of paddy followed by wheat in which panchgavya, matka khad and jeevamrit resulted in 60% reduction in percent frequency of fungal pathogens as compare to control (16–48%). Seeds of maize treated with panchgavya also showed complete reduction of Aspergillus sp and Fusarium sp.
