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.

Identification of a Second Asian Soybean Rust Resistance Gene in Hyuuga Soybean [PDF]

Phytopathology®, 2011
Asian soybean rust (ASR) is an economically significant disease caused by the fungus Phakopsora pachyrhizi. The soybean genes Rpp3 and Rpp?(Hyuuga) confer resistance to specific isolates of the pathogen. Both genes map to chromosome 6 (Gm06) (linkage group [LG] C2).

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 ...

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 ...

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 ...

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
