    Potential use of the essential oil ofTrachyspermum ammi against seed-borne fungi of Guar (Cyamopsis tetragonoloba L. (Taub.)) (1993)

    Notes: Abstract Essential oils isolated from leaves and seeds of seven umbelliferous plants were tested against the growth ofAspergillus flavus. Those from seeds ofTrachyspermum ammi, Cuminum cyminum, Carum carvi, Daucus carota and from leaves ofAnethum graveolens exhibited antifungal activity against the test fungus. Amongst these, oil from seeds ofTrachyspermum ammi was most toxic. Its minimum inhibitory concentration was 300 ppm, at which it exhibited fungistatic but not phytotoxic properties, when tested at 200, 300 and 400 ppm. The fungitoxic potency ofTrachyspermum seed oil remained unchanged after a long storage period and at high inoculum density of the test fungus. The oil was thermostable and was more efficaceous than the fungicides Agrosan G.N., Benlate, Ceresan, Dithane M-45 and Thiovit commonly used for the control of plant diseases.

    Fungitoxicity of some higher plants againstRhizoctonia solani (1983)
    Springer
    Plant and soil 72 (1983), S. 91-94 
    Details
    ISSN: 1573-5036
    Keywords: Anti-fungal activity ; Chenopodium ambrosioides ; Fungitoxicity ; Rhizoctonia solani
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Leaves ofChenopodium ambrosioides exhibited strong fungitoxicity against the mycelial growth ofRhizoctonia solani causing damping off diseases of some seedlings. Minimum inhibitory concentration of the fungitoxic constituent isolated in form of essential oil, was found to be 1000 ppm at which it was fungicidal in nature. It exhibited broad range of antifungal activity and did not show any phytotoxicity on the germination and seedling growth ofPhaseolus aureus.

    Atmospheric biopollutants of Gorakhpur (1983)
    Springer
    Water, air & soil pollution 19 (1983), S. 215-221 
    Details
    ISSN: 1573-2932
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract The present study on atmospheric biopollutants in the vicinity of Gorakhpur was carried out from July 1979 to June 1981 by exposing adhesive slides. Pollen grains, fungal spores and organic matters were found to be maximum amongst the traps. Plant parts (floral parts, hairs, pollens, tissue segments), algal parts; animal parts (danders, insects with pollen, insect eggs, legs, mouthparts, scales, spicules, wings) and identified and unidentified organic parts loaded with bacteria/fungi were found in the air throughout year. Diurnal, monthly and seasonal variations in atmospheric biopollutants were studied quantitatively. The study of diurnal periodicity revealed maximum trapping of air-borne particles during morning and noon. The particles were maximum during the transition periods of the seasons (during mid October to mid November and March) and a minimum in June and August. The intensity of biopollutants increased with wind velocity and decreased with rainfall.
