OBJECTIVE To examine the acaricidal effects of the essential oil of Cymbopogon citratus leaf extract (lemongrass) and ethanolic Azadirachta indica leaf extract (neem) against house dust mites Dermatophagoides farinae (D. farinae) and Dermatophagoides pteronyssinus (D. pteronyssinus). METHODS Twenty-five adults mites were placed onto treated filter paper that is soaked with plant extract and b...

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...

Escherichia coli O157:H7 (EcO157) shed in cattle manure can survive for extended periods of time and intervention strategies to control this pathogen at the source are critical as produce crops are often grown in proximity to animal raising operations. This study evaluated whether neem (Azadirachta indica), known for its antimicrobial and insecticidal properties, can be used to amend manure to ...

Objectives: Neem (Azadirachta indica country like Bangladesg, Indiaand had probably been the most useful medicinal plant in South Asia.From leaf to root, each and every part of the neem treehas also beenused in Bangladesh and neighboring countries for over two thousand years for their medicinal properties. natural products chemists by Ayurveda. achieved regarding the biological activities and m...

In a previous laboratory experiment, extracts of neem (Azadirachta indica A. Juss.) and Gliricidia sepium Jacquin, locally known as mata-raton, used to control pests on crops, inhibited emissions of CO(2) from a urea-amended soil, but not nitrification and N(2)O emissions. We investigated if these extracts when applied to beans (Phaseolus vulgaris L.) affected their development, soil characteri...

Neem (Azadirachta indica) seedlings were found infested by the brown burrower bug, Scaptocoris castanea Perty, in December 2009, in the county of Tupaciguara, Minas Gerais state. Symptoms observed varied from leaf yellowing and stem drying, reduction in root size and number to plant death. This is the first report of S. castanea attacking neem plants.

The efficacy of different extracts of neem leaf on seed borne fungi Aspergillus, Rhizopus and chemical characterization of the neem leaf extracts were studied in vitro on the culture medium. The growth of both the fungal species was inhibited significantly (p<0.01) and controlled with both alcoholic and water extract of all ages and of the concentrations used. The alcoholic extracts of neem lea...

BACKGROUND Different strains of influenza virus are affecting a large number of people worldwide. Many synthetic antiviral medicines are available for influenza virus in the market. But still there is a need for the development of universal drugs against these strains of influenza virus. METHODS For this purpose conserved residues within the influenza virus nucleoprotein have been retrieved. ...

Diabetes Mellitus is affecting people of all age groups worldwide. Many synthetic medicines available for type 2 diabetes mellitus in the market. However, there is a strong requirement for the development of better anti-diabetes compounds sourced especially from natural sources like medicinal plants. The extracts from the leaves of neem (Azadirachta indica) is traditionally known to have anti-d...

Phytochemical studies were carried out on the plant parts of Jatropha curcas (L.) and Azadirachta indica (A. Juss) found in the South Eastern parts of Nigeria with a view to highlighting their pre-existing secondary metabolites which have varieties of biological activities attributed to them. Qualitative and quantitative analysis of seven secondary metabolites (alkaloids, tannins, saponins, fla...
