Asian Soybean Rust Resistance: An Overview [PDF]

Journal of Plant Pathology & Microbiology, 2015
Asian soybean rust caused by Phakopsora pachyrhizi, occurs in all soybean production regions of the world. Rust is the most destructive foliar disease of soybean and can cause yield losses of over 80%. To date, six race-specific resistance genes have been identified in plant introductions. However, races of P. pachyrhizi able to overcome the resistance

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.

Molecular polymorphisms that underlie trait variation in crops: Lessons learned from soybean. [PDF]

Plant Genome
Abstract Genetic variation within a germplasm is important in crop improvement, providing a foundation for breeders to develop new varieties. Traits of agronomic and economic importance are often mapped to identify the genetic basis of observed phenotypes, oftentimes using quantitative trait locus (QTL) analysis.

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.

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 ...

Characterization of soybean genotypes for Asian soybean rust reaction [PDF]

Crop Breeding and Applied Biotechnology, 2010
Our objective was to characterize soybean experimental lines for Asian soybean rust reaction. In the 2004/2005 growing season, three experiments were conducted with middle-cycle and three with late-cycle genotypes, designed in randomized blocks with four replications. Twelve experimental lines and two cultivars of each cycle were used.

Mobile Application for Asian Soybean Rust Tracking in Brazil

Anais do VII Workshop de Computação Aplicada à Gestão do Meio Ambiente e Recursos Naturais (WCAMA 2016), 2016
Brazil is the second-largest soybean producer. With the arrival of Asian soybean rust in the Western Hemisphere in 2001, a considerable amount of resources has been allocated to understand and control this important yield-limiting disease. Due its rapidly dissemination, in 2004, the federal government led an effort to create the Asian soybean rust ...

A pigeonpea gene confers resistance to Asian soybean rust in soybean [PDF]

Nature Biotechnology, 2016
Asian soybean rust (ASR), caused by the fungus Phakopsora pachyrhizi, is one of the most economically important crop diseases, but is only treatable with fungicides, which are becoming less effective owing to the emergence of fungicide resistance. There are no commercial soybean cultivars with durable resistance to P.

The Asian Soybean Rust in South America [PDF]

, 2011
Soybean is infected by two species of fungi that cause the rust: the Phakopsora meibione (Arth.) Arth. (American soybean rust), which is native from American continent, existing from Puerto Rico to southern Brazil and not cause concerns for farmers and the Phakopsora pachyrhizi Sydow & Sydow (Asian soybean rust), a serious disease which causes a high ...
