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...

Nitrification inhibitors may be potential management strategy to reduce N2O emissions in irrigated rice (Oryza sativa L.). A field experiment was conducted to evaluate chemically synthesized as well as locally available neem plant products on N2O emissions, from an irrigated rice at New Delhi, India. Emission of nitrous oxide (N2O) was monitored during 70 days by closed chamber method in rice (...

Background: A neem-based conditioner lotion (ONC) used against head lice was previously tested clinically and shown to be relatively ineffective. To improve the activity against lice and their eggs, it was reformulated into a silicone vehicle (NNC) as part of a project to improve pediculicidal medical devices. An ultrasound nit comb was also developed to be used in conjunction with the neem lot...

Effect of some plant extracts against damping-off disease of some winter vegetable was studied in the net house. Seed treatment with neem leaf, garlic clove, allamonda leaf, ginger rhizome, kalijira seed, bel leaf, turmeric rhizome, katamehedi leaf and onion bulb were evaluated against damping-off, seed germination and growth characters of tomato, eggplant and chilli seedlings. All the treatmen...

Biologically-based spray treatments, including nucleopolyhedroviruses, neem, and spinosad, were evaluated as supplemental controls for the fall armyworm, Spodoptera frugiperda (J. E. Smith), and corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), on transgenic sweet corn, Zea mays (L.) (Poales: Poaceae), expressing a Cry1Ab toxin from Bacillus thuringiensis Berliner (Bacillales: Ba...

Tetranychus evansi Baker & Pritchard is an important pest of solanaceous plants, including tomatoes. This mite is characterized by a high reproductive rate, which leads to high population growth in a short period of time causing important economic damage. Control of T. evansi is mainly through synthetic acaricides. In searching for environmentally friendly control measures, we evaluated the eff...

Neem (Azadirachta indica) is a multifunction plant. Its leaves and seeds can be used as a traditional medicine. One of the benefits of neem seeds is that they can serve as antibacteria. It happens because neem seeds contain certain substances which can impede the growth of Salmonella thyposa and Staphylococcus aureus bacteria. The aims of this research were to find out the efectiveness of soaki...

To study the effect of neem extract on the growth and viable count of foodborne and contaminated bacteria and determine its active inhibitors. Different concentrations of methanolic extracts (200 mg/ml, 150 mg/ml, 100 mg/ml, 50 mg/ml and 25 mg/ml) were prepared. One-hundred microliters of standardized test organisms was treated with solvents or extract. The extract was tested against Gram-posit...

Feeding trials were conducted for 28days to evaluate the nutritional value of Neem (Azadirachta indica) leaf meal on the performance and economics of deep litter managed finisher broiler production. The neem leaves were harvested, air dried and milled to become neem leaf meal. It was included in the broiler finisher diets at 0,2.5,5.0,7.5 and 10% levels respectively. One hundred and fifty (150)...
