Cultivar mixtures can be used to improve the sustainability of disease management within farming systems by growing cultivars that differ in their disease resistance level in the same field. The impact of canopy aerial architecture on rain-splash dispersal could amplify disease reduction within mixtures. We designed a controlled conditions experiment to study single splash-dispersal events and ...
BACKGROUND AND AIMS French wheat grains may be of little value on world markets because they have low and highly variable grain protein concentrations (GPC). This nitrogen-yield to yield ratio depends on crop nitrogen (N) fertilization as well as on crop capacity to use N, which is known to vary with climate and disease severity. Here an examination is made of the respective roles that N remobi...
مقدمه: Zymoseptoriatritici گونهای از قارچهای رشته ایاست و بیماری شایع سوختگی سپتوریایی برگ گندم (STB) را موجب میشود. اسید سالیسیلیک (SA) نقش کلیدی در واکنشهای دفاعی گیاه داشته و مقاومت اکتسابی عمومی (SAR) را القا میکند. با این حال، سهم SA در برهمکنش Z. tritici– گندم در بیماری سوختگی سپتوریایی برگ کاملا روشن نیست. در این مطالعه مشخص شد در حضور غلظتهای افزایشی SA از رشد هیفها و جوانهزنی...
Parastagonospora nodorum, the causal agent of Septoria nodorum blotch (SNB), is an economically important pathogen of wheat (Triticum spp.), and a model for the study of necrotrophic pathology and genome evolution. The reference P. nodorum strain SN15 was the first Dothideomycete with a published genome sequence, and has been used as the basis for comparison within and between species. Here we ...
Fungicides continue to be essential for the effective control of plant diseases. The azoles class of fungicides has been the leading agents for the control of fungal pathogens of plants since their introduction in the mid 1970s. This class of fungicides is also called sterol demethylation inhibitors (DMIs) because they inhibit the formation of cytochrome P450 sterol 14 alpha-demethylase (450 14...
Breeding of grain crops for phytoimmunity in the FSBSU FASC Northeast is carried out conditions natural and artificial epiphytotics. Every year, more than 1000 samples winter rye, spring soft wheat, barley oats their own breeding from VIR collection are studied. In studies conducted on snow mold, root rot, powdery mildew, brown stem rust, septoria blight, fusarium head ergot; wheat – loose smut...
