Among biotic stresses, Alternaria leaf spots caused by Alternaria brassicae and A. brassicicola and black rot caused by Xanthomonas campestris pv. campestris are major limiting factors in brassica cultivation across the world. Because of seed-borne nature of these pathogens primarily, disease-free conservation as well as exchange of brassica seeds...

Studies on distribution profiling and infection indexing of seed-borne fungi of sorghum germplasm from seventeen states of India revealed the presence of a total of 43 species belonging to 23 genera of fungi. Based on average infection index, Fusarium verticillioides (26.27 ±20.96), Alternaria alternata (19.30 ±15.05), A. niger (14.40 ±7.42), Fusar...

In rapeseed and mustard, the major diseases (downy mildew, white rust, Alternaria blight and Sclerotinia stem rot) cause 37–47%loss in pod formation and 17–54% reduction in grain yield. The identification of new sources of resistance is a high priority in breeding programs. About 3000 germplasm accessions of Indian mustard were evaluated under mult...

The cultivation of green gram (Vigna radiata (L.) and black gram (Vigna mungo (L.) Hepper) in Jharkhand, India, is adversely affected by most destructive yellow mosaic disease (YMD), but the etiological agent in this region is not identified so far. Disease incidence and severity as high as 100 per cent in farmers' fields is common, often resulting...

The importance of wheat as staple food is well known as it is most popular, widely grown cereal crop of the world (Breiman and Gaur, 1995). Due to fast growing population of the world especially in the developing countries the demand of wheat is keep on increasing (Rajaram, 2000; Nagarajan, 2005). The present global wheat demand is about 640 Millio...

A simple modified handmade needle technique for obtaining pure cultures directly from a mixed population of fungi was developed which resulted in purification of several seed-borne fungal species producing exogenous macrospores on seeds of different crops within a minimum possible time viz., Alternaria, Bipolaris, Botrytis and Cercospora. Pure cult...

Anti-potato and anti-tomato polyclonal antibodies were developed for serodiagnosis of bacterial wilt. Optimum antigen concentration was standardized as 7.5 ×106 cells for potato (Solanum tuberosum L.) and 5 × 107 cells for tomato (Solanum lycopersicum L.) per well and dilution of antibacterial antibody was optimized as 1:250 for potato and 1:175 fo...
