Fungicide Spraying Programs Reducing Asian Soybean Rust Impact on Soybean Yield Components

Journal of Agricultural Science, 2022
Soybean is one of the leading agricultural commodities, and Brazil is currently the largest producer globally. Despite this, fungal diseases as Asian Soybean Rust (ASR) are among the primary limiters of high crop yields in Brazilian fields. Losses caused by the biotrophic fungus Phakopsora pachyrhizi can reach up to 90%, depending on weather conditions,

EFFICIENCY LOSS OF RECORDED FUNGICIDES FOR THE CONTROL OF ASIAN SOYBEAN RUST IN CENTRAL REGION OF BRAZIL

Revista de Agricultura Neotropical, 2016
Due to grower allege of low efficiency of triazole fungicides in recent years in Central Brazil on the control of Asian soybean rust (Phakopsora pachyrhizi), this study was undertaken to demonstrate the efficiency loss of products registered for rust and

Relationship between biochemical and photosynthetic traits with Asian soybean rust [PDF]

Anais da Academia Brasileira de Ciências, 2018
Asian soybean rust (Phakopsora pachyrhizi - ASR) is one of the major diseases that occur in soybean and causes great damage to commercial crops. Therefore, the goal of this work was to investigate the relationship between biochemical and photosyntetic parameters in soybean with ASR.

Association of hydrogen peroxide with commercial fungicide formulations in the control of Asian soybean rust

Ciência Rural, 2021
: In recent years, there have been reductions in the efficacy of the fungicidal control of Phakopsora pachyrhizi, thereby hindering the management of soybean rust and compromising crop yield.

Identification of the soybean HyPRP family and specific gene response to Asian soybean rust disease. [PDF]

Genet Mol Biol, 2013
Soybean [Glycine max (L.) Merril], one of the most important crop species in the world, is very susceptible to abiotic and biotic stress. Soybean plants have developed a variety of molecular mechanisms that help them survive stressful conditions. Hybrid proline-rich proteins (HyPRPs) constitute a family of cell-wall proteins with a variable N-terminal ...

Asian Soybean Rust Severity Sowed in Different Seasons

Journal of Agricultural Science, 2020
In on-farm trials, the foliolar severity of Asian soybean rust was evaluated in 44 areas, in three regions of Mato Grosso sown in December (2019) and February (2020). Several susceptible cultivars were used in different crop systems; insect pests and weeds were controlled with different management systems by the farmers.

Effect of adding fungicide to mixtures of triazoles and strobilurins in the control of downy mildew and Asian soybean rust

Pesquisa Agropecuária Tropical, 2019
Fungicides used to control the Asian soybean rust are composed almost entirely of mixtures involving the systemic (triazoles) and meso-systemic (strobilurins) modes of action.

On the current status of Phakopsora pachyrhizi genome sequencing

Frontiers in Plant Science, 2014
Recent advances in the field of sequencing technologies and bioinformatics allow a more rapid access to genomes of non-model organisms at sinking costs. Accordingly, draft genomes of several economically important cereal rust fungi have been released in ...

Transcriptional profile of genes involved in the production of terpenes and glyceollins in response to biotic stresses in soybean [PDF]

Genetics and Molecular Biology, 2020
Terpenes produced by plants comprise a diverse range of secondary metabolites, including volatile organic compounds (VOCs). Terpene VOC production may be altered after damage or by biological stimuli such as bacterial, fungal and insects, and subsequent ...

Alternative products on the control of asian rust soybean

Research, Society and Development, 2021
In recent years, it has been observed a significant expansion of the organic market. In this context, the main phytosanitary problem of soybean in the organic system is Asian rust (Phakopsora pachyrhizi), for which it is difficult to control, considering the restriction of products authorized for use in the organic system and the limitation of research
