Quantification of leaf stripe, Pyrenophora graminea, in barley seed by real-time PCR [PDF]

, 2005
In some years, large amounts of organic seed lots are discarded due to the presence of high levels of seed-borne diseases. In barley it is especially the presence of the fungal species Pyrenophora teres (barley net blotch) and P.

Challenges facing the management of pesticide resistance in weeds, diseases and insect pests in European agriculture and the future of effective IPM implementation

Pest Management Science, Volume 82, Issue 4, Page 2838-2843, April 2026.
Opinion on pesticide resistance and management in the European Union (EU) and United Kingdom (UK) is presented cognisant of changes in regulation that impact on mode of action availability and cropping system choice. Abstract In recent times, pesticide resistance has been managed reasonably effectively, either proactively or reactively, by monitoring ...

Mating type idiomorphs of Pyrenophora teres in Turkey [PDF]

Zemdirbyste-Agriculture, 2018
Pyrenophora teres f. maculata (Ptm) and Pyrenophora teres f. teres (Ptt) causes spot form and net form of net blotch diseases of barley, respectively. Although both forms of P. teres are morphologically similar, their symptoms and genetic background differ. In this study, 175 single spore (109 Ptm and 66 Ptt) isolates obtained from different regions of

Control of seed borne diseasees in organic seed propagation [PDF]

, 2004
Introduction The key control measure of plant diseases in organic agriculture is crop rotation, mixed cropping and moderate fertilization. A wide range of plant diseases can be controlled or minimized in this way.

Synthesis and Biological Profile of Substituted Pyrrolidinyl Carboxamides for Acyl‐ACP Thioesterase Inhibition

European Journal of Organic Chemistry, Volume 29, Issue 12, 23 March 2026.
The work outlined herein covers a series of novel herbicidal lead structures that possess a pyrrolidinyl pyrazole carboxamide scaffold as a key structural feature, carrying further substituted benzyl side chains. Based on scaffold hopping approaches from known fungicidal and herbicidal compounds and utilizing an optimized synthetic approach, a broader ...

Exotic Genetic Lineages Rapidly Replace Established Exserohilum turcicum Populations in the Swiss Rhine Valley

Plant Pathology, Volume 75, Issue 2, March/April 2026.
A metagenomic survey of northern corn leaf blight in Swiss maize revealed a temporal shift from a dominant European clonal lineage to genetically diverse tropical lineages between 2016–2017 and 2021–2022. Pool sequencing enabled cost‐effective monitoring and highlights changing pathogen epidemiology relevant for durable maize resistance breeding ...
