Secondary Metabolites of Calonectria hemileiae Inhibit Hemileia vastatrix Urediniospore Germination: Evidence for Chemical Mediation in a Mycoparasitic Interaction

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Calonectria hemileiae, an antagonist of the coffee leaf rust pathogen Hemileia vastatrix, produces low‐molecular weight secondary metabolites that inhibit urediniospore germination. These metabolites likely mediate interfungal interactions and show potential for the development of biofungicides against coffee leaf rust.

Evaluation of Virulence of Phakopsora pachyrhizi and P. meibomiae Isolates [PDF]

Plant Disease, 2006
Asian soybean rust (ASR), caused by Phakopsora pachyrhizi and recently discovered for the first time in continental United States, has been of concern to the U.S. agricultural industry for more than 30 years. Since little soybean rust resistance is known, and resistance is often difficult to detect or quantitate, we initiated a project to develop a ...

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,

Integrative genomic analyses reveal candidate genes for the Ur‐3 and Ur‐7 rust resistance loci in common bean

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Bean rust, caused by Uromyces appendiculatus, severely limits the productivity of common bean (Phaseolus vulgaris L.), an essential source of protein and micronutrients in human diets worldwide. Durable disease management relies primarily on host resistance; however, the molecular architecture of several key rust resistance loci remains ...

Use of AFLP markers to estimate molecular diversity of Phakopsora pachyrhizi

Electronic Journal of Biotechnology, 2015
Background: Asian soybean rust (SBR) caused by Phakopsora pachyrhizi Syd. & Syd., is one of the main diseases affecting soybean and has been reported as one of the most economically important fungal pathogens worldwide. Knowledge of the genetic diversity

Host‐Induced Silencing of Rhizoctonia Solani 5‐Enolpyruvylshikimate‐3‐Phosphate Synthase Impairs Its Virulence in Rice

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3573-3593, June 2026.
ABSTRACT Sheath blight disease of rice caused by the fungal pathogen R. solani AG1‐IA remains a big threat to rice production worldwide. A limited genetic variation in rice for tolerance to this pathogen and little success in understanding how it defeats host defence are major reasons behind it.

Use of isolated fungicides for the control of Phakopsora pachyrhizi in soybean

International Journal for Innovation Education and Research, 2020
The occurrence of diseases in soybean crop has negatively affected its development and caused significant losses in productivity. Among the diseases, Asian rust caused by the fungus Phakopsora pachyrhizi Sydow stands out because of its high severity. As a way of controlling, chemical fungicides is a tool used to mitigate the damage.

Fungicide Resistance Profile of Monilinia fructicola and Monilinia laxa Isolates From Commercial Peach and Nectarine Orchards in the Ebro Valley, Spain

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Combining phenotypic sensitivity testing with molecular characterization, we identify diverse tolerant Monilinia phenotypes in Spanish orchards. The integration of genetic insights with fungicide response reveals early resistance development requiring updated control strategies.

Prospects for Durable Resistance Against an Old Soybean Enemy: A Four-Decade Journey from Rpp1 (Resistance to Phakopsora pachyrhizi) to Rpp7

Agronomy, 2019
Soybean rust (SBR), caused by Phakopsora spp., is a major global concern for soybean producers. SBR causing fungi are polycyclic and obligate biotrophs, rendering the study of their biology particularly tedious.
