Seed borne mycoflora of maize was tested by using blotter, agar plate and deep freezing methods as recommended by ISTA. Of the 100 samples collected from different places of Pakistan, a total number of 56 species belonging to 23 genera of fungi were isolated and identified. About 70% of the samples were infested with Aspergillus flavus, A. niger, A. wentii(More)
Twenty one seed samples of lentil (Lens culinaris L.) collected from various localities of Pakistan viz., Karachi (12), Sukkur (1), Swabi (1), Mardan (2), Ghazi (1), Wah (1), Faisalabad (1), Lahore(1) and Hub(1) were analyzed for the detection of seed-borne mycoflora using standard blotter, agar-plate and deep-freezing methods as suggested by ISTA.

Bacillus thuringiensis (Bt10) and Rhizobium meliloti (R5) with and without locally available nursery fertilizers viz., flourish, frutan, NPK, urea and fish meal were used to study their effect on the growth and suppression of soil borne root infecting fungi viz., Macrophomina phaseolina, Rhizoctonia solani and Fusarium spp., on mung bean and okra plants.(More)
The biological potential of different microbial antagonists viz., Bacillus thuringiensis, Rhizobium meliloti, Aspergillus niger and Trichoderma harzianum was examined by coating the seeds with gum arabic, glucose, sugar and mollases in the suppression of root rot fungi viz., Macrophomina phaseolina, Rhizoctonia solani and Fusarium spp., on okra and(More)
Maize seeds with 8, 12,16 and 20% moisture content stored at 4,25, 35 and 40oC for 6 months showed heavy (98100%) fungal infection at 20% moisture after 30 days of storage at all temperatures of 4, 25, 16 and 35°C. Infection of Aspergillus species was highest in seeds with 20% moisture level stored at 25 and 40oC , however lower number of fungi were(More)
Present research work was carried out for the management of root rot fungi with wild plant part capsules and pellets formulation in soil. When application of pellets and capsules was carried out with Prosopis juliflora stem, leaves and flowers showed significant reduction in disease incidence and enhancement in growth and physiological parameters.(More)
Change in biomass, nitrogenase activity, chlorophyll and type of epiphytic algal contamination were determined for Azolla microphylla and A. pinnata, as a function of pH. These studies were done in a polyhouse at a constant temperature. The growth rate increased till pH 6 in both species, but sharply declined at pHs 7, 8, and 9. A. microphylla showed better(More)
