Powders from three medicinal plants were evaluated for their efficacy as contact and fumigant insecticides on cowpea bruchid, Callosobruchus maculatus (Fab.) in the laboratory at ambient tropical conditions of temperature and relative humidity. The plant powders tested included Capsicum frutescens L. (fruit and seed), C. annum Miller (fruit and seed) and(More)
The powders and extracts of Azadirachta indica A. Juss and Piper guineense (Schum and Thonn) seeds were bioassayed for their insecticidal potential against the lesser grain borer, Rhizopertha dominica (Fabr.) in the laboratory at 30+2C and 70+5% relative humidity. The powders were applied at rates 0.5, 1.0, 2.0 and 4.0g/20g of wheat grains. The extracts of(More)
In this study, levels and estimated daily intake (EDI) of two toxic elements, Cd and Pb, and eight essential elements: Ca, P, Zn, Mn, Co, Cu, Se and Mo, were determined in Nigerian rice samples. The mean levels of Cd, Pb and Co were 5.43±0.88, 38.66±5.42, 25.8±3.18 ng/g. The mean levels of Ca, P, Zn, Mn, Cu, Se and Mo were 71.5±7.31, 951±52.0, 10.2±0.63,(More)
Powders and extracts of Azadirachta indica, Zanthoxylum zanthoxyloides, Anacardium occidentale and Moringa oleifera were assessed in the laboratory at ambient temperature of 28±2C and relative humidity of 75±5% for their insecticidal activity against Sitophilus oryzae, Oryzaephilus mercator and Ryzopertha dominica infesting paddy rice.
