Groundnut or peanut (Arachis hypogaea L.) is one of the important economic oilseed crops of the world. The cultivated groundnut belongs to family Fabaceae, subfamily Papilionaceae. Groundnut is grown in nearly 100 countries. It occupies 21.7 million ha worldwide with a total production of 38.6 million tonnes during 2011 (FAOSTAT, 2011). Among the soil-borne fungal diseases of groundnut, stem ro...

Black rot caused by Xanthomonas campestris pv. campestris (Pam.) Dowson is the most destructive disease of cauliflower causing huge loss to the farmers throughout the world. Since there are limited sources of resistance to black rot in B. oleracea (C genome Brassica), exploration of A and B genomes of Brassica was planned as these were thought to be potential reservoirs of black rot resistance ...

In June 2012, leaf spot and stem rot were observed on Wilford Swallowwort plants grown in Cheonan, Korea. Three fungal isolates obtained from the diseased leaves and stems were identified as Stemphylium lycopersici, based on morphological, cultural, and molecular characteristics and pathogenicity. This is the first report of leaf spot and stem rot on Wilford Swallowwort caused by S. lycopersici.

Sclerotinia head rot is a major disease of sunflower in the world, and quantitative trait loci (QTL) mapping could facilitate understanding of the genetic basis of head rot resistance and breeding in sunflower. One hundred twenty-three F2:3 and F2:4 families from a cross between HA 441 and RHA 439 were studied. The mapping population was evaluated for disease resistance in three field experimen...

Metallic silver nanoparticles have been reduced from silver nitrate by employing the extracellular enzymatic machinery of edible White button Mushroom (Agaricus bisporus). The physical properties of these particles, size and shapes have been determined using techniques like TEM, FTIR and XRD and were reported in our earlier report. But, what stands of paramount importance in the presen...
