The seeds of mung bean varieties were treated with the chemical mutagens viz EMS and SA to study pollen sterility. EMS with 0.05%, 0.10%, 0.15% concentrations and Sodium azide with 0.01%, 0.02%, 0.03% concentrations. Pollen sterility is directly proportional to concentrations ie. increase in concentrations increases pollen sterility.

Aqueous leaf extracts of Commelina diffusa was evaluated for food value. The results show that the proximate and vitamin compositions of Commelina. Diffusa included mainly moisture (83.36%), carbohydrate (6.32%), vitamin C (44.80 mg/100g dry weight), vitamin B3 (63.18mg/100g) and vitamin B2 (8.30 mg/100g) respectively. The mineral contents of the defatted leaf extracts were found to be Na (69.32mg/100g), Ca (232.00mg/100g) and Mg (84.28mg/100g). The proximate, vitamin and mineral compositions obtained suggest that the leaves, as cheap sources of vitamins C, B3 and B2, as well as other macro-and micronutrients, can be incorporated into human and animal diet to meet their recommended daily allowances. The content of flavonoids and vitamin C in the leaf extracts also suggests possible anti-oxidant effects of these leafy vegetables.

The present study was undertaken to evaluate in-vitro antifungal activity of Semecarpus anacardium Linn. oil against four fungal pathogens, viz. Curvularia penniseti, Curvularia lunata, Fusarium oxysporum f. sp. ciceris and Helminthosporium maydis using poisoned food technique. The DMSO extract of S.anacardium oil was found to be more or less active against almost all tested pathogenic fungi with a varied spectrum of reduced growth. C.lunata has shown 93.3% inhibition and F.oxysporum and H.maydis have shown 94.4% inhibition and 100% mycelial inhibitions at 15% and 18% concentrations of the extract respectively. Whereas, C.penniseti was found to be quite sensitive that showed 88.9 inhibitions at 10% concentration but it showed 100% inhibition at 18% concentration.

Indoor Curvularia spores are potential sensitizers in human beings, their prevalence is important for diagnosis and environmental management of asthma. Human beings are known to suffer from major allergens such as fungal spores, pollen grains and house dust present in the atmosphere. Inhalation of air borne fungal spores is the main causative factor for respiratory allergic diseases in human beings. Indoor survey of aeromycoflora was performed by using Rotorod air sampler, Petri plate exposure and eosinophil count of asthmatic patient in Ambajogai. The highest concentration of Curvularia spores was recorded in the house of patient. ‘W’ (12.08 %) in the month of September 2000.
