Spray adjuvants can be employed in the foliar application of fertiliser to ensure adhesion of aqueous sprays to the waxy surfaces of foliage (wetters), to improve coverage of spray on foliage (spreaders), to minimise weathering of fertiliser deposits on foliage (stickers/extenders), and to increase the uptake of fertiliser into foliage (humectants, pH modifiers, and penetrants). Even with impro...

We examined effects of a first nitrogen (N) fertilizer application on upper-canopy needle morphology and gas exchange in ~20-m-tall loblolly pine (Pinus taeda L.) exposed to elevated carbon dioxide concentration ([CO 2 ]) for 9 years. Duke Forest free-air CO 2 enrichment (FACE) plots were split and half of each ring fertilized with 112 kg ha –1 elemental N applied in two applications in March a...

Moringa oleifera (M. oleifera) is an angiosperm plant, native of the Indian subcontinent, where its various parts have been utilized throughout history as food and medicine. It is now cultivated in all tropical and sub-tropical regions of the world. The nutritional, prophylactic, and therapeutic virtues of this plant are being extolled on the Internet. Dietary consumption of its part is therein...

The ethnolic extract of the leaves of Moringa oleifera Lam. (Fam. Moringaceae) was tested for antimicrobial activities against Gram Positive - Bacillus cereus, Bacillus subtilis Staphylococcus aureus, Sarcina lutea: Gram negative - Escherichia coli and Acid fast Mycobacterium phlei. Significant antimicrobial activity of the extract was found in this study.

The alkali preparation of the root and fresh leaf juice of Moringa oleifera possessed significant dose -depen-dent anti-ulcer activity in experimentally induced acute gastric ulcers with aspirin, the anti-ulcer effect of the alkali preparation of the root seems to be more pronounced than that of the fresh leaf juice. Te anti-ulcer activity of the alkali preparation of the root could be due to i...

Moringa oleifera, seed (PKM 1) was examined for extracted oil recovery under the different designed conditions using Central composite face centered design of Response surface methodology. The kinetics of extraction was investigated and its parameters were determined based on a second order model. The optimum conditions were found at 3.6 h reaction time, temperature, 67.84°C and solvent to soli...

In the course of our studies on the isolation of bioactive compounds from the roots of Moringa oleifera, a traditional herb in southeast Asia, rare aurantiamide acetate 4 and 1,3-dibenzyl urea 5 have been isolated and characterized. And also, this is the first report of isolation from this genus. Isolated compound inhibited the production of TNF-alpha and IL-2; further compound 5 showed signifi...

The midgut pH of gypsy moth (Lymantria dispar) larvae was significantly lower when larvae were fed acidic foliage. At 30 min after the start of a feeding bout, larvae feeding on bigtooth aspen (foliage pH = 6.04) had average midgut pH levels of 10.16, while larvae feeding on red oak foliage (foliage pH = 3.84) had average midgut pH levels of 9.36. Midgut pH was also significantly reduced when l...
