Selection strategies of segregant soybean populations for resistance to Asian rust Estratégias de seleção de populações segregantes de soja para resistência à ferrugem-asiática

Pesquisa Agropecuária Brasileira, 2009
The objective of this work was to identify the best selection strategies for the more promising parental combinations to obtain lines with good resistance to soybean Asian rust (Phakopsora pachyrhizi). Two experiments were carried out in the field during

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.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

First Report of Phakopsora pachyrhizi on Soybean in Costa Rica

Plant Disease, 2015
Phakopsora meibomiae (Arthur) Arthur has been reported to occur in several legume species in the tropical regions of Central and South America. In Costa Rica, this pathogen was initially reported as P. pachyrhizi Sydow (1); however, to our knowledge, P. pachyrhizi has not been detected in Costa Rica.

In vivo sensitivity of Phakopsora pachyrhizi to DMI and QoI fungicides [PDF]

Summa Phytopathologica, 2015
In in vivoexperiments the sensitivity of 18 isolates of Phakopsora pachyrhizifrom several regions of Brazil to IDM fungicides (cyproconazole, epoxiconazole and tebuconazole and an IQE (pyraclostrobin) were evaluated. The assessments were based on leaflet uredia density.

Decoding stress resilience in soybean: Regulatory networks and precision breeding under climate change

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2838-2868, August 2026.
This review covers recent progress in the understanding of stress‐responsive regulatory networks in soybean and highlights emerging genomic and breeding strategies. Integrating molecular insights and precision breeding will help to accelerate the development of climate‐resilient soybean cultivars.

Partial Resistance to Soybean Rust in Diverse Soybean Germplasm Under Field Conditions in Uganda

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
312 soybean genotypes screened for rust resistance in Uganda. Consistent partial resistance identified in both MG1 and MG2. Rust index is highly heritable and strongly correlated with lesion type. Low G × E in MG1 indicates stable resistance expression. Top genotypes identified for breeding rust‐resistant African cultivars. ABSTRACT Soybean rust (SBR),

Detection of Soybean Rust caused by Phakopsora pachyrhizi in Northwestern Argentina

Plant Disease, 2005
Asian soybean rust, caused by Phakopsora pachyrhizi, is regarded as one of the most destructive diseases of soybean (Glycine max (L.) Merr.). In Argentina, it was first detected in the province of Misiones in the northeast near Paraguay and Brazil during the 2001-02 growing season (2).
