Avaliação de parâmetros monocíclicos e da densidade da ferrugem asiática (Phakopsora pachyrhizi) em diferentes genótipos de soja e posições de copa. [PDF]
RESUMO: A ferrugem da soja destacou-se nas últimas safras devido à alta severidade que vem causando nas lavouras de soja. Diversos estudos estão em andamento, para buscar informações sobre a resistência genética dos cultivares atualmente plantados.

First Report of Phakopsora pachyrhizi on Soybean in Costa Rica
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.

ABSTRACT Soybean (Glycine max (L.) Merr.) is one of the important legumes globally, serving as an affordable and valuable protein source for humans and livestock. However, selecting the most suitable genotype across diverse environmental conditions remains a major challenge due to significant genotype‐by‐environment interactions (GEI). In addition, the

Selection strategies of segregant soybean populations for resistance to Asian rust. [PDF]
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

Winter Survival of the Soybean Rust Pathogen, Phakopsora pachyrhizi, in Florida [PDF]
Soybean rust (SBR) survival and host availability (kudzu, Pueraria spp.) were assessed from November 2006 through April 2007 at six sites from the panhandle to southwest Florida. Micro loggers recorded both temperature and relative humidity hourly at each location.

ABSTRACT RNA‐based pesticides represent a transformative approach in agricultural disease management, offering an environmentally sustainable alternative to conventional chemical fungicides. However, key challenges such as rapid RNA degradation in the environment and inefficient uptake hinder widespread adoption.

Development of Brazilian Soybean Cultivars Well Adapted to Cerrado and Rust-Tolerant [PDF]
The major diseases limiting soybean growth and yield must be either controlled or mitigated. Among these, soybean rust is the most harmful; in addition, Phakopsora pachyrhizi populations less susceptible to both IDM and IQe fungicides were observed ...

Puccinia horiana, the causal agent of chrysanthemum white rust, has developed quantitative resistance to QoI fungicides through one to four substitutions, selected from F90I, N256S, Y257N, L275F, F278L, M295V or L299F in cytochrome b (Cytb). ABSTRACT Quinone outside inhibitors (QoIs) are a major class of agricultural fungicides.

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