Septoria tritici blotch (STB) is caused by the ascomycete Zymoseptoria and one of predominating diseases in wheat (Triticum aestivum) Europe. The control STB highly reliant on frequent fungicide applications. primary objective this study was to assess sensitivity levels Z. different groups. fungicides included were epoxiconazole, prothioconazole-desthio, tebuconazole, fluxapyroxad. A panel 63 isolates from Estonia, Latvia, Lithuania, 10 Finland tested. Fungicide testing carried out as a...
Worldwide, barley/cereal yellow dwarf viruses (YDVs) are the most widespread and damaging group of cereal viruses. In this study, we applied high-throughput sequencing technologies (HTS) to perform a virus survey on symptomatic plants from 47 fields in Estonia. HTS allowed assembly complete genome sequences for 22 isolates RPS, barley GAV, PAS (BYDV-PAS), PAV (BYDV-PAV), OYV (BYDV-OYV). We also assembled near-complete putative novel species BYDV-OYV Swedish samples meadow fescue. Previously,...
High-throughput sequencing technologies were used to identify plant viruses in cereal samples surveyed from 2012 2017. Fifteen genome sequences of a tenuivirus infecting wheat, oats, and spelt Estonia, Norway, Sweden identified characterized by their distances other sequences. Like most tenuiviruses, the this contains four genomic segments. The isolates found different countries shared at least 92% nucleotide sequence identity level. planthopper Javesella pellucida was as vector virus....
Efficacy of the fungicide tebuconazole was tested in 2 treatment regimes 3 spring barley varieties over three years (20032005). The impact on control major pathogens Pyrenophora teres and Cochliobolus sativus, as well kernel yield studied course field trials. treatments had a strong infection P. increased variable disease conditions. For more resistant genotype, application relatively low returns because much higher level biological resistance small disease-related reductions. susceptible...
Abstract Pyrenophora teres (net blotch) and Cochliobolus sativus (spot blotch), the most widely spread diseases in Northern Baltic region, have high impact on cereal production. The effect of three levels fertilisation two fungicide treatments severity barley diseases, grain yield quality traits (protein content, test weight, thousand kernel weight (TKW), grading) was tested during a period years. Weather conditions growing season highly determined disease severity, quality. In addition,...
Ramularia leaf spot (RLS) is a disease of barley (Hordeum vulgare) caused by the fungus collo-cygni Sutton & Waller (Rcc). Rcc causes necrotic lesions, premature senescence leaves, and yield reduction. Under Estonian conditions, there are usually no spots on upper leaves prior to flowering. In 2009, 2010, 2012, symptoms similar those RLS were observed spring winter in several agricultural regions. Approximately 30% plants affected fields symptomatic. Symptoms not 2011, which was dry hot...
Ramularia leaf spot (RLS) caused by the fungus collo-cygni (Rcc) is affecting barley fields throughout temperate regions worldwide. The first finding of RLS in Estonia was reported on spring 2012 and since then area infection has been widening Estonia. This work carried out to monitor natural Rcc two winter cultivars follow artificial fungal a PCR-based assay. Using our approach, we could detect presence pathogen leaves before appearance disease symptoms at early growth stages. Response...
Little research has been published about the occurrence of diseases in faba bean such as chocolate spot, ascochyta blight, or rust Northern Europe. There is also little data impact sowing rate variety on disease development. Therefore, purpose this study was to assess and seeding severity at Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie (BBCH) 75 (which when 50% pods have reached full length). Five varieties were tested from multiple European countries: Bauska (Latvia),...

Six varieties of field pea (Pisum sativum L.) were sown at two sowing rates over years to assess the impact on disease occurrence in a Baltic climate. The used Bruno (Latvia), Capella (Sweden), Clara Kirke (Estonia), Onward (Greece), and Vitra (Latvia). 120 seeds per m2 144 m2. increase rate by 20% did not influence diseases. Variety influenced incidence pea. most damaged pod spot (Ascochyta blight caused Ascochyta spp.) least Clara. variety downy mildew (caused Peronospora viciae) was...
Abstract A spelt diversity panel including 80 genotypes of winter was tested for resistance to common bunt, leaf blotch, powdery mildew, rust, stem rust and yellow rust. The reaction diseases investigated in field trials carried out at multiple European locations between 2013 2019. Resistance assessed after artificial inoculation or natural infestation by visual scoring symptoms. presence genes postulated using molecular markers. It found that the hulls plays a role as passive factor against...
A total of 111 local pollen beetle populations were collected from both winter and spring oilseed rape fields, in the main growing regions Estonia between 2015−2019. The objective was to analyse insecticide-susceptibility population (in form Brassicogethes aeneus). samples tested for sensitivity lambda-cyhalothrin, thiacloprid, chlorpyrifos. efficacy insecticides varied considerably by region. We observed a clear decrease susceptibility lambda-cyhalothrin but chlorpyrifos remained stable...
