Cereal production is limited by many different factors. Leaf diseases are often well known, while diseases on roots are more difficult to identify. Root diseases are often caused by oomycetes, fungus-like microorganisms that live for years in soil and on old root debris, parasitizing the roots of wheat, barley, and many other plant species. Adult plants may be stunted and/or chlorotic, as if nitrogen deficient. Symptoms are often difficult to recognize and diagnose. Severe infections cause a general root rot. Within the project group we have noticed both Aphanomyces and Pythium spp. on roots of barley and Pythium spp. on wheat. These pathogens are overlooked and they cause diseases that can be important in all cereal-producing areas. In this project, we aim to identify the pathogens, assess the pathogenicity on different hosts and cultivars in the crop rotation and also evaluate the effects of seed treatments and lime.
Skördarna av spannmål begränsas av många faktorer. Bladsjukdomar är ofta väl kända, medan sjukdomar på rötter är svårare att identifiera och kartlägga. Rotsjukdomar orsakas ofta av oomyceter, svamplika organismer som kan leva i jord och växtrester i tiotals år. Symptom av dessa patogener är ofta diffusa och plantorna kan bli kortväxta och gulnande, som om de har näringsbrist. Vi har sett att det finns en art av Aphanomyces, som angriper rotsystemet i korn och även arter av Pythium i både korn och vete. Dessa patogener kan påverka skörden i mycket större omfattning än vad som hittills är känt. Projektets syfte är att öka produktiviteten i svensk spannmålsodling genom att uppmärksamma och minska skördeförlusterna orsakade av dessa rotsjukdomar. Målet är att identifiera patogenerna, testa patogeniteten på några vanligt förekommande lantbruksgrödor och även på olika sorter av korn och vete. Vi avser även att utvärdera motåtgärder i form av fröbetning och kalkning.

Agriculture in plain-lands is often specialized in crop production, with no on-farm use of ley as animal fodder, and crop rotations that often includes only annual crops (e.g. oilseed rape, cereals and sugar beets). At the same time, integrating ley in arable cropping systems generates several …
