Summary Bipolaris sorokiniana (teleomorph Cochliobolus sativus) is the causal agent of common root rot, leaf spot disease, seedling blight, head blight, and black point of wheat and barley. The fungus is one of the most serious foliar disease constraints for both crops in warmer growing areas and causes significant yield losses. High temperature and high(More)
ABSTRACT In search of new durable disease resistance traits in barley to control leaf spot blotch disease caused by the necrotrophic fungus Bipolaris sorokiniana (teleomorph: Cochliobolus sativus), we developed macroscopic and microscopic scales to judge spot blotch disease development on barley. Infection of barley was associated with cell wall penetration(More)
The concept of development is reviewed in terms of sustainability. Food production in India driven by pressure from an increasing human population uses 90,000 t per year of technical-grade pesticide: 12% of this is fungicide and a good part is insecticide for the control of vectors of plant viruses. A change in the cropping pattern and irrigation have(More)
