Race-specific resistance of wheat to Puccinia graminis f. sp. tritici is primarily posthaustorial and often involves the induction of a hypersensitive response (HR). The aim of this study was to investigate host defense responses induced in interactions between P. graminis f. sp. tritici races and wheat lines carrying different race-specific stem rust resistance (Sr) genes. In incompatible inte...

background and objectives: septoria leaf blotch disease (stb) caused by the fungus mycosphaerella graminicola (fuckel) j. schroeter (anamorph: septoria tritici roberge), is one of the most destructive foliar diseases of wheat in the world, that its worldwide damage in outburst years is about 30 to 50 per cent. the pathogen is a bipolar heterotallic ascomycete that its sexual life cycle is repea...

Diseases can greatly lower wheat yield and grain quality. Leaf rust, Stagnospora (Septoria) glume blotch, Septoria leaf blotch, and powdery mildew have historically been the most damaging diseases on wheat in Alabama. Stripe rust has recently emerged in the Deep South as a very destructive disease of wheat. Field cropping history, cultivar selection, and weather patterns all have a tremendous i...

ABSTRACT Silicon (Si) amendments in the form of exogenously supplied nutrient solution or calcium silicate slag protect wheat plants from powdery mildew disease caused by the fungus Blumeria graminis f. sp. tritici. The most striking difference between Si- and Si+ plants challenged with B. graminis f. sp. tritici was the extent of epidermal cell infection and colonization by B. graminis f. sp. ...

Phenotyping for quantitative resistance to Septoria tritici blotch (STB), one of the most economically devastating diseases durum wheat (Triticum Desf.) in North African region, is a limiting factor breeding progress. Here we tested main phenotypic markers aggressiveness affecting host damage and pathogen reproduction reported earlier studies measuring differences resistance. A collection 11 Tu...

A two-year (2018/19 and 2019/20) field experiment was carried out to evaluate the efficacy of recently developed fungicide combinations (with different modes action) towards fungal diseases on seven bread eight durum wheat varieties. The trial performed at FIELDLAB experimental station University Perugia (Italy). were assessed under natural pressure except for Fusarium head blight (FHB) which a...

Wheat is one of the most economically important field crops worldwide. Foliar diseases are a major threat to wheat productivity and primarily managed by implementing less susceptible cultivars using fungicides. With “Farm Fork” strategy under consideration European Union reduce pesticide usage 50% 2030, this elucidates importance utilizing decision support systems (DSS) optimize fungicide appli...
