Considerable Azadirachtin Production in Neem Cell Culture under Abiotic Elicitor Induction
In this study the effect of different concentrations of some abiotic elicitors (salicylic acid, jasmonic acid, cadmium chloride and sodium chloride) with different incubation times (3, 6, 9 and 12) on azadiractin production and cell growth in the cell culture of the Iranian native Neem were investigated. Cell growth rate was measured by changes in dry cell weight and it was used as a basis for ...
متن کاملControl of Diamondback Moth by Application of Neem Extracts
Some extracts from neem seeds/neem seed kernels can give satisfactory to good control of diamondback moth, Plutella xylostella (L.), in cabbage and other crucifers. Water extracts prove most effective, sometimes even at low concentrations as low as 12.5 g of seed kernels per liter of water, provided the raw material contains sufficient azadirachtin. Neem could be developed into products suitabl...
متن کاملA Comparative Study on the Toxicity of a Synthetic Pyrethroid, Deltamethrin and a Neem Based Pesticide, Azadirachtin to Poecilia reticulata Peters 1859 (Cyprinodontiformes: Poeciliidae)
Increased use of chemical pesticide results in the excess inflow of toxic chemicals, mainly into the aquatic ecosystem (Baskaran et al., 1989; Kalavathy et al., 2001). The aquatic flora and fauna are affected by the toxic substances which eventually enter in to their systems or bring about external damages (Pant and Singh, 1983; Hodson, 1988; Johal and Dua, 1995). Several species of fish are su...
متن کاملActivity and biological effects of neem products against arthropods of medical and veterinary importance.
Botanical insecticides are relatively safe and degradable, and are readily available sources of biopesticides. The most prominent phytochemical pesticides in recent years are those derived from neem trees, which have been studied extensively in the fields of entomology and phytochemistry, and have uses for medicinal and cosmetic purposes. The neem products have been obtained from several specie...
متن کاملDetermination of azadirachtin in agricultural matrixes and commercial formulations by enzyme-linked immunosorbent assay.
An enzyme-linked immunosorbent assay (ELISA) was developed for azadirachtin (aza), a biopesticide from the neem tree (Azadirachta indica A. Juss). The immunogen was synthesized by epoxidation using the furan ring in the aza molecule. Rabbits were immunized with either bovine serum albumin (BSA)-azadirachtin or ovalbumin (OA)-azadirachtin conjugate. Evaluation of the antisera by antibody capture...
