Effect of aqueous leaf extracts of 8 allelopathic tree species viz., Accacia nilotica (L.) Willd ex Del., Alstonia scholaris (L.) R. Br., Azadirachta indica (L.) A. Juss., Eucalyptus citriodora Hook, Ficus bengalensis L., Mangifera indica L., Melia azedarach L. and Syzygium cumini (L.) Skeels was studied on germination and seed-borne mycoflora of wheat (Triticum aestivum L.). Wheat seeds were s...

background & aim: the plants of the greenhouse have been affected by infestation of the pest trialeurodes vaporariorum, called greenhouse whitefly, which markedly reduced production. synthetic insecticides have been widely developed and, their extensive use has brought about disadvantages, like environmental disturbance, pest resistance, lethal effects on non target organisms and toxicity t...

ABSTRACT. Biosorption is a cost effective tool for removing heavy metals from aqueous solutions. In the present study, M. azedarach biomass has been used biosorption of Ni(II) ion solution. The effect pH, contact time, concentration and temperature were separately studied. optimum pH was found to be 6.0. 92% founded, when 25 mg/L initial concentrations at room temperatures in 60 min. It also ob...
