MISHRA, D. K. 2005. Germplasm variability in neem (Azadirachta indica). A variant neem (Azadirachta indica) tree, growing in the Arid Forest Research Institute (AFRI), Jodhpur, India was compared with the nearby growing normal tree and a neem tree from Thailand of the same age. The tree has now attained the height of 6 m and collar diameter of 38 cm. The tree differed morphologically, viz. leaf...

A study was conducted to evaluate the effectiveness of three selected botanicals namely leaf extract of Neem (Azadirachta indica), Debdaru (Polyalthia longifolia) and datura (black) (Datura metel) along with Bavistin (Carbendazim) and BAU-biofungicide (Trichoderma harzianum) against leaf spot disease (tikka) of groundnut caused by Cercospora arachidicola and Cercosporidium personatum at the Fie...

Objective: The study was to evaluate the antidermatophytic activity of the ethanol, ethyl acetate and hexane extract of Neem ( Azadirachta indica) leaves against dermatophytes isolated from patients with dermatophytosis. Methods: Clinical samples from 200 patients were subjected to (KOH) examination and culture isolation. Causative agents were identified macroscopically and microscopically. The...

The global scenario is now supporting the development of modern drugs from less toxic plant products with proven medicinal properties. Each part of neem plant [Azadirachta indica A. Juss] reportedly have various medicinal properties and has been in use in many continents for centuries. Recently, a fractionated neem-leaf extract known as IRAB with reported activities against Malaria, HIV/AIDS an...

A laboratory experiment was conducted to investigate the efficacy of different plant derivatives against the development of the cowpea weevil, Callosobruchus maculatus (F) (Coleoptera: Bruchidae) fed on cowpea, Vigna unguiculata (W) seeds. The leaf extracts of romatic plants, Murraya koenigii and Azadirachta indica (A.Juss) were evaluated for their growth, adult mortality and oviposition inhibi...

The present study was carried out to screen and evaluate antimicrobial activity of leaf and bark extracts of Azadirachta indica. Ethanol and aqueous extract of leaves and barks of A. indica (Neem) were tested against Escherichia coli and Staphylococcus aureus which are known to be resistant to various antibiotics. Neem materials which were used during this study were collected from Bugesera dis...

Experiments were carried out to evaluate the toxicity of six botanicals, Bazna (Zanthoxylum rhetsa), Ghora-neem (Melia sempervirens), Hijal (Barringtonia acutangula), Karanja (Pongamia pinnata), Mahogoni (Swietenia mahagoni) and Neem (Azadirachta indica) against red flour beetle, Tribolium castaneum Herbst. Leaf and seed extracts were prepared by using acetone, methanol and water as solvents. T...

Induced resistance is an important component of disease-resistance response of plants, and is accompanied by increased capability for activating defense responses upon pathogen ingress or elicitor treatment. Aqueous leaf extract of neem (Azadirachta indica Juss.) provided the control of Alternaria leaf spot pathogen (Alternaria sesami) of sesame (Sesamum indicum L: Syn. S. orientale L). Treatme...

The effect of aqueous leaf extract of Azadirachta indica (Neem) on reproduction was studied on male albino rats. The study was divided into three groups of six animals each. The first group (I) received distilled water serve as control. The second and third groups (II and III) of animals were administered the aqueous leaf extract daily at 250mg/kg body wt., and 350mg/kg body wt., respectively f...
