Digital information communication technologies (DICTs) play an ever-more prominent role in politics, from the technologically sophisticated presidential campaign of Barack Obama to the Twitter-inspired Occupy Wall Street movement. However, not all political groups embrace technology to the same degree. Little scholarly attention has been paid to understanding why some groups adopt DICTs and use...

Increases in two extracellular peroxidases were observed following inoculation of barley (Hordeum vulgare L.) with the powdery mildew pathogen (Erysiphe graminis DC.: Fr. f. sp. hordei Em. Marchal). The more prominent isozyme, P8.5, was purified from intercellular wash fluids by acetone precipitation, ion-exchange chromatography, isoelectric focusing, and gel filtration. Purified P8.5 is a heme...

Systemic effect of two plant growth-promoting rhizobacterial (PGPR) strains,viz., Pseudomonas fluorescens (Pf4) and P. aeruginosa (Pag), was evaluated on pea (Pisum sativum) against the powdery mildew pathogen Erysiphe pisi. Foliar spray of the two PGPR strains was done on specific nodal leaves of pea and conidial germination of E. pisi was observed on other nodal leaves,distal to the treated o...

The effect of methanolic extract of cashewnut (Anacardium occidentale) shell extract was seen on conidial germination of Erysiphe pisi and powdery mildew development in pea (Pisum sativum). Maximum conidial germination inhibition of E. pisi on glass slides was observed at 300 ppm. Similar effect on floated pea leaves was observed after 48 h at the same concentration. Conidial germination on int...

The alkaloid securinine was assessed against spore germination of some plant pathogenic and saprophytic fungi (Alternaria alternata, Alternaria brassicae, Alternaria brassicicola, Curvularia lunata, Curvularia maculans, Curvularia pallenscens, Colletotrichum musae, Colletotrichum sp., Erysiphe pisi, Helminthosporium echinoclova, Helminthosporium spiciferum, Heterosporium sp.). Spore germination...
