Melia azedarach L. extracts were studied in comparison with selected biorational insecticides against the citrus leafminer Phyllocnistis citrella Stainton under field conditions. Citrus limon (L.) Burm. F. trees were exposed to: Melia extracts of green and mature fruits, Neem oil (30% a.i.), abamectin (1.8% a.i.) and control. Two sprays of each treatment (except for Melia mature fruit extract) ...

A biological invasion of non-native plants is spreading into our natural areas and rights-of way. In the present work, Melia azedarach (Meliaceae) known for its high allelopathic potential is used to investigate its biopesticide capacity on the common model used in bioassays: Raphanus sativus (R. sativus). Exposure of R. sativus to M. azedarach (aqueous/ethanolic) leaves extracts result on toxi...

Present study was conducted to evaluate the fungicidal property of methanolic extracts of some indigenous plants of Karachi such as Hibiscus rosa-sinensis (leaves), Thespesia populnea (leaves, stem and fruit), Withania somnifera (leaves and stem), Solanum surattense (shoot) and Melia azedarach (fruit) against common soil-borne phytopathogens viz., Macrophomina phaseolina, Rhizoctonia solani and...

Systematic fractionation of a fruit extract from Argentine Melia azedarach L., which was monitored by an insect antifeedant bioassay, led to the isolation of meliartenin, a limonoid antifeedant, which existed as a mixture of two interchangeable isomers. At 4 microg/cm2 and 1 microg/cm2, the isomeric mixture was as active as azadirachtin in strongly inhibiting the larval feeding of Epilachna pae...

BACKGROUND The increasing use of nanoparticles and nanocomposite in pharmaceutical and processed food industry have increased the demand for nontoxic and inert metallic nanostructures. Chemical and physical method of synthesis of nanostructures is most popular in industrial production, despite the fact that these methods are labor intensive and/or generate toxic effluents. There has been an inc...

Screening of phenolic constituents in leaves of Cedrela serrata, Toona ciliata, Azadirachta indica and Melia azedarach was done by reversed phase high performance liquid chromatography (RP-HPLC). The phenolic compounds were identified by comparison with authentic standards. The phenolic acids identified in all plants leaves extract were gallic acid, protocatechuic acid, p-hydroxy benzoic acid, ...
