Characteristics of fungicide resistance in Asian soybean rust (Phakopsora pachyrhizi) in Paraguay for 2022-2023: insights from genetic mutations and molecular dynamics simulations. [PDF]

Pest Manag Sci
Phakopsora pachyrhizi in Paraguay showed diverse resistance to DMI, SDHI, and QoI fungicides at both regional and intra‐field levels, likely driven by target mutation genes. Abstract BACKGROUND Phakopsora pachyrhizi, the causative agent of Asian soybean rust, poses a major threat to soybean production in South America. The rising incidence of fungicide

Spectral responses at visible and near-infrared wavelengths of soybean plants to fungicides

Ciência Rural, 2022
: The study evaluated the efficacy and soybean spectral responses to fifteen foliar fungicide mixtures labeled to control Asian soybean rust. Canopy level reflectance was measured using a multispectral camera onboard a multirotor drone before and two ...

Breeding for Resistance to Soybean Rust [PDF]

Plant Disease, 2005
Soybean rust occurs in all major soybean-growing regions of the world including the North American mainland. Soybean rust, caused by Phakopsora pachyrhizi, is the most destructive foliar disease of soybean, and yield losses of over 50% are common when environmental conditions are conducive for disease development. Heavily infected plants defoliate and

Spatio-Temporal Risk and Severity Analysis of Soybean Rust in the United States

Journal of Agricultural and Resource Economics, 2008
Soybean rust is a highly mobile infectious disease and can be transmitted across short and long distances. Soybean rust is estimated to cause yield losses that can range between 1%-25%.

CHEMICAL CONTROL OF ASIAN SOYBEAN RUST AS A FUNCTION OF CULTIVAR, ROW SPACING AND SPRAY BAR SUPPORT SYSTEMS [PDF]

Engenharia Agrícola, 2019
Product deposition and foliar surface cover are highly impacting factors on the efficiency of foliar fungicides applied to soybean cultivars, due to their low mobility, with side effects on Asian soybean rust (ASR) control.

Spray solution deposition and Asian rust control in soybean cultivars

Revista Brasileira de Engenharia Agrícola e Ambiental, 2021
The control of Asian soybean rust depends on fungicide efficacy and the application technology; however, the leaf architecture of soybean cultivars may also interfere in disease control.

Epidemiology of Soybean Rust in Soybean Sentinel Plots in Florida [PDF]

Plant Disease, 2011
Since its discovery in the southeastern United States in 2004, soybean rust (SBR) has been variable from year to year. Caused by Phakopsora pachyrhizi, SBR epidemics in Florida are important to understand, as they may serve as an inoculum source for other areas of the country.

Characteristics of superior soybean breeding lines tolerance to rust (Phakopsora pachyrhizi Syd.)

Biosaintifika: Journal of Biology & Biology Education, 2016
Soybean rust caused by Phakopsora pachyrhizi is one of the most important diseases which limits soybean production. The aim of this study was to evaluate the resistance of 28 superior soybean lines and their tolerance to rust.
