Silver nanoparticles have gained considerable interest in recent decades due to their antimicrobial activity and are used water disinfection, wound healing, food packaging, plant protection. This study tested the potential of silver synthesized using neem (Azadirachta indica) leaf extract against Alternaria solani causes early blight disease tomato plants. The pathogen was isolated from infecte...

Effects of cyperin 10 EC and neem extract on pollinators, fruit setting and fruit quality of mango was investigated. Number of pollinators visited mango inflorescences was higher in morning in comparison to noon and afternoon. In control plants, average 25.67 pollinators visited within 30 minutes which was higher than cyperin 10 EC (20.00) and neem extract treated (24.34) plants. The pollinator...

Laboratory studies were carried out to isolate, identify and control the fungi associated with fruit rot of tomato (Lycopersicon esculentum). Aspergillus viridae, Penicillium digitatum and Rhizopus sp were isolated from samples collected from Lokoja, Kabba, Okene, Anyigba and Ankpa, all in Kogi State, Nigeria. Plant extracts employed to control the vegetative mycelial growth were from neem (Aza...

1School of Public Health and Institute of Health Research, Tehran University of Medical Science, Tehran, Islamic Republic of Iran. Received: 22/10/02; accepted: 18/08/03 ABSTRACT An insecticide containing azadirachtin, a neem tree (Azadirachta indica) extract, was tested against mosquito larvae in the Islamic Republic of Iran under laboratory and field conditions. LC50 and LC90 values for Neema...

Fungi of the genus Fusarium are well known plant pathogens, cause several vascular diseases and are producers of toxins. In vitro assays evaluated the effects of Neem (Azadirachta indica) oil on the diameter of colonies, dry weight, spore production, spore viability and production of Fusaric Acid toxin on Fusarium oxysporum f. sp. medicagenis and Fusarium subglutinans isolates. Effects of Neem ...

In vitro efficacy of five indigenous plants namely Bishkatali (Polygonum hydropiper), Neem (Azadirachta indica), Papaya (Carica papaya), Korolla (Momordica charantia) and Mahogany (Swietenia macrophylla) were studied against the development of Ascaridia galli eggs from July 2007 to May 2008. Fresh juice, extracts and dust of leaves were tested. Fresh juice of leaves were trialed at 5%, 10% and ...

AIM The objective of this study was to isolate endophytic bacteria from Azadirachta indica (neem) leaves, their identification and investigate their antibacterial activity against three Gram-positive bacteria, Staphylococcus aureus, Streptococcus pyogenes and Bacillus cereus and Gram-negative bacteria Escherichia coli, Salmonella Typhimurium and Klebsiella pneumoniae. MATERIALS AND METHODS Fr...

Ethanolic extract of bark of Azadirachta indica showed potent spermicidal activity when tested on rat spermatozoa in vitro. When the extract was applied in 1:1 and 1:2 ratio at tree different concentration using wet drop method, cent percent mortality of spermatozoa was observed within 10 seconds. 10% concentration of the extract was considered as an effective dose.

a green house study was conducted to evaluate the comparative efficacy of pasteuria penetrans under the influence of organic amendments of four oil seed cakes namely azadirachta indica (locally known as neem), castor (ricinus communis), mustard (brassica campestris) and citrullus (citrullus colocynthis)on suppression of populations of meloidogyne incognita in chilli. oil seed cakes were applied...
