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.

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 ...

Nickel-enriched soybean seeds generate plants more resistant to Asian soybean rust [PDF]

Bragantia, 2021
ABSTRACT Asian soybean rust (ASR), triggered by Phakopsora pachyrhizi, can cause great yield losses on soybean and nickel (Ni) has potential to control this disease. This study evaluated the effect of using soybean seeds with different Ni contents on ASR control by performing two experiments.

POTENTIAL DISTRIBUTION ZONES FOR SOYBEAN RUST (Phakopsora pachyrhizi) IN MEXICO

Ecosistemas y Recursos Agropecuarios, 2015
Asian Soybean Rust is one of the most important soybean diseases. Since the past decade, some im- portant soybean production areas in America, like Brazil and the United States of America, have been affected by this disease.

Characterization of three soybean landraces resistant to Asian soybean rust disease [PDF]

Molecular Breeding, 2020
AbstractPhakopsora pachyrhizi is an obligatory biotrophic fungus that causes Asian soybean rust (ASR) disease. ASR control primarily involves chemical control and the use of resistant soybean cultivars carrying an Rpp (resistance to P. pachyrhizi) gene. This study aimed to characterize the ASR resistance of three soybean Asian landraces.

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.
