Securing adequate nutrition for the growing population is a major development agenda being pursued by many African policy makers. However, hunger and malnutrition are still among the major economic and human development challenges in many African countries. In Nigeria, the growing dimension of the nation’s food problem cumulatively impacts many development indicators. This paper therefore sough...

The Colorado potato beetle, Leptinotarsa decemlineata (Say), is one of the most damaging insect pests of potato, Solanum tuberosum L. Novaluron is a relatively new benzoylphenyl urea insect growth regulator with good activity against this pest. Earlier studies revealed that feeding on potato foliage treated with novaluron induces reversible egg hatch inhibition in adult Colorado potato beetles....

Moringa oleifera commonly referred to as the drumstick tree is a plant from the Moringaceae family. It is a medicinal plant that was found to be loaded with different bioactive chemicals or secondary metabolites such as vitamins, minerals, saponins, alkaloids, flavonoids, carotenoids etc. which are involved in enhancing a long term health benefits. M. olifera is among the most promising species...

, ABSTRACT. 1. The preference of Corythucha arcuata (Say) (Heteroptera: Tingidae) for the foliage of Quercus alba L. (Fagaceae) grown under water deficit was examined. Potted Q.alba saplings were grown under controlled levels of water deficit in a glasshouse. Adult C. arcuata were exposed to excised Q.alba foliage under controlled conditions in a growth chamber, and feeding preference assessed ...

Moringa oleifera Lam. (Moringaceae) is highly valued plant reported to have various biological activities. Considering the antioxidant properties of Moringa oleifera (MO), the chemopreventive property of hydro-ethanolic extract of drumsticks was evaluated on DMBA induced renal carcinogenicity. Groups of 10 male mice were preadministered with MO (200 and 400mg/kg body weight) and standard (0.5%B...

To assess water contamination and the relative effectiveness of three options for point-of-use water treatment in South India, we conducted a 6-month randomized, controlled intervention trial using chlorine, Moringa oleifera seeds, a closed valved container, and controls. One hundred twenty-six families participated. Approximately 70% of public drinking water sources had thermotolerant coliform...

The effectiveness of aqueous extract of seven locally available medicinal plants i.e. Trachyspermum ammi (seeds), Zingiber officinale (rhizome), Tinospora cordifolia (leaves), Cymbopogon citratus (leaves), Moringa oleifera (bark) were evaluated against the plant pathogenic fungus i.e. Fusarium oxysporum f. sp. lini (causing wilt in linseed). The plant extracts were screened for their antagonist...

Co-aggregation was attempted in Azorhizobium caulinodans ORS-571 with other agriculturally important microorganisms such as Azospirillum brasilense MTCC-125, Azotobacter chroococcum MTCC-446, Bacillus megatherium MTCC-3353, and Pseudomonas fl uorescens MTCC-4828 to develop coaggregates with multiple benefi ts using seed powders of diff erent plants viz., Moringa oleifera, Strychnos potatorum an...

Nitrogen (N) is essential for plant production, but N uptake imposes carbon (C) costs through maintenance respiration and fine-root construction, suggesting that an optimal C:N balance can be found. Previous studies have elaborated this optimum under exponential growth; work on closed canopies has focused on foliage only. Here, the optimal co-allocation of C and N to foliage, fine roots and liv...

Extrapolation of the effects of ozone on seedlings to large trees and forest stands is a common objective of current assessment activities, but few studies have examined whether seedlings are useful surrogates for understanding how mature trees respond to ozone. This two-year study utilized a replicated open-top chamber facility to test the effects of subambient, ambient and twice ambient ozone...
