Effects of aldicarb and fungicides on Pratylenchus penetrans populations, root rot and net blotch severity on barley [PDF]

, 1995
Les populations du nematode des lésions (Pratylenchus penetrans), lequel produit des lésions nécrotiques dans le cortex racinaire, ont été mesurées dans des parcelles expérimentales d'orge (Hordeum vulgare) en 1988,1989 et 1990. Les nematodes des lésions

Global field trials show the advantages of beta regression compared with logit transformation and quasi‐likelihood for the analysis of percentage plant disease severity

Annals of Applied Biology, Volume 188, Issue 3, Page 904-916, May 2026.
Disease severity in crop protection field trials is commonly assessed as a proportion represented as a percentage. Traditional statistical analysis uses transformation to logit or angle. This study compares analyses based on the beta distribution and the quasi‐likelihood method with the logit transform using a large global data set of field trials ...

Interactions between fungal plant pathogens on leaves. Especially simultaneous development of Rhynchosporium secalis and Drechslera teres on barley [PDF]

, 2005
Disease causing fungi are a major potential threat to yield in both organic and conventional cereal production, and generally several different species of pathogenic fungi are found together on the same plants in the field. This PhD thesis concludes that

Breeding Malting Barley under Stress Conditions in South America

Czech Journal of Genetics and Plant Breeding, 2004
The annual average area sown with barley (Hordeum vulgare) in South America during 1999-2003 was 795 000 ha. In Argentina, Brazil, Chile and Uruguay, two-rowed spring cultivars are used mostly for malt production.

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 ...

Seedling Response of Iranian Barley Landraces to Pyrenophora teres f. teres and Pyrenophora teres f. maculata

Journal of Agricultural Sciences, 2019
Net blotch caused by Pyrenophora teres is an important pathogen of barley plants worldwide. There are two biotypes of the fungus. Pyrenophora teres f. teres (Ptt) causes the net form of the disease and Pyrenophora teres f.

Protection of winter barley against net blotch using modern fungicides

Siberian Herald of Agricultural Science
The results of a three-year (2020–2022) study of the efficacy of the modern fungicide Ace, CSC of Russian production (pyraclostrobin - 80 g/l + prothioconazole - 40 g/l + tebuconazole - 160 g/l) against the pathogen of barley net blotch are presented. Barley is an important food, feed and fodder grain crop, ranking fourth in the world in terms of area ...
