Effects of inter-varietal diversity, biotic stresses and environmental productivity on grain yield of spring barley variety mixtures [PDF]

, 2012
Varietal seed mixtures tend to increase and stabilize crop yields, yet their application is sparse. Large-scale cultivation of variety mixtures may require a better understanding of how inter-varietal interactions and their interaction with the ...

Sanitary state and yielding of spring barley as dependent on soil tillage method

Acta Agrobotanica, 2012
The effects of traditional tillage cultivation (control treatment), no tillage (instead of tillage the soil was loosened with scruff), and direct sowing (with a special drill into unploughed soil) on the health of spring barley cultivar.

Monitoring fungicide resistance frequencies – a case study of barley net blotch

Pest Management Science, EarlyView.
Droplet digital PCR revealed the frequency of alleles associated with decreased sensitivity to demethylation inhibitor (DMI) and succinate dehydrogenase inhibitor (SDHI) fungicides in Pyrenophora teres from barley net blotch in Western Australia. The findings highlight field‐level allele dynamics and emerging risks to fungicide efficacy.

Assessment of Resistance of Barley Varieties to Diseases in Polish Organic Field Trials

Agriculture
Leaf rust and net blotch are two important fungal diseases of barley. Leaf rust is the most important rust disease of barley, whereas net blotch can result in significant yield losses and cause the deterioration of crop quality.

Molecular diagnostic methods can prevent unnecessary rejection of organic seed lots [PDF]

, 2004
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.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
