Septoria sonchi causes Sonchus oleraceus leaf spot in Iran [PDF]

Australasian Plant Disease Notes, 2013
A survey was done on leaf samples of Sonchus oleraceus with symptoms of leaf spot from different areas of Hamadan province, Iran during the summer to autumn period in 2009. The causal agent of this disease was studied in terms of morphological characteristics. The causal agent of symptoms was identified as Septoria sonchi.

Mycobiome Simplification in Wheat Is Associated With the Pathogen Parastagonospora nodorum

Molecular Ecology, Volume 35, Issue 14, July 2026.
ABSTRACT Plant mycobiomes are essential to plant health, yet their assembly under biotic stressors such as pathogen infection remains poorly understood. Plant pathogens can influence microbial community composition through direct antagonism and suppression of host immune responses, potentially altering mycobiome composition in ways that could affect ...

Stomatal Closure, a Conserved Spore Concentration‐Dependent Response Mediated by Different Stb Genes to Avirulent Isolates of Zymoseptoria tritici

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Inoculation with different avirulent Zymoseptoria tritici isolates induces stomatal closure in wheat lines carrying either the Stb9 or Stb16q resistance genes. The proportion of closed stomata was positively associated with inoculum concentration, consistent with increased Z. tritici penetration attempts through stomata.

Identifying and managing Cercospora leaf blight in soybean: From scouting to best management practices

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Maximizing soybean [Glycine max (L.) Merr.] yield requires effective management of Cercospora leaf blight (CLB), a significant foliar disease that can reduce productivity and grain quality. The impact of CLB is particularly notable in regions such as the mid‐southern United States, where species of Cercospora, predominantly C. cf. flagellaris,

Septoria Leaf Spot of Banana: A Newly Discovered Disease Caused by Mycosphaerella eumusae (Anamorph Septoria eumusae) [PDF]

Phytopathology®, 2000
A previously undescribed leaf spot disease of banana has been discovered in southern and Southeast Asia. The fungus identified as the causal agent of this leaf spot has a Mycosphaerella teleomorph stage and a Septoria anamorph stage. Isolation and reinoculation of the fungus to banana reproduced symptoms and confirmed its pathogenicity.

Phenotypic and genetic resistance to Septoria blotch disease in European wheat varieties

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Zymoseptoria tritici, the causal agent of Septoria tritici blotch (STB), poses a critical threat to wheat (Triticum aestivum L.) production in temperate Europe, underscoring the need for durable genetic resistance. Here, we screened 151 winter wheat varieties at the seedling stage using a mixed inoculum of five virulent isolates.
