Comparative Susceptibilities of Legume Species to Infection by Phakopsora pachyrhizi [PDF]

Plant Disease, 2008
Knowledge of the host range of Phakopsora pachyrhizi is important to agriculture in the United States because of the distinct possibility that economic losses could occur to crops other than soybean. Furthermore, it is possible that alternative hosts could provide a means of overwintering of the pathogen, providing inoculum to initiate epidemics in ...

First Report of Soybean Rust (Phakopsora pachyrhizi) in Nigeria

Plant Disease, 2001
Rust caused by Phakopsora pachyrhizi H. & P. Sydow was observed for the first time on soybean (Glycine max [L.] Merr.) in Nigeria during the 1999 main soybean growing season. The disease was first noticed on soybean farms in Oniyo and neighboring villages located about 20 km west of Ogbomoso (Long. 4° 02′ E and Lat.

Novel Phakopsora pachyrhizi extracellular proteins are ideal targets for immunological diagnostic assays. [PDF]

Appl Environ Microbiol, 2012
ABSTRACTPhakopsora pachyrhizi, the causal agent of Asian soybean rust (ASR), continues to spread across the southeast and midsouth regions of the United States, necessitating the use of fungicides by producers. Our objective in this research was to identify ASR proteins expressed early during infection for the development of immunodiagnostic assays. We

Selection strategies of segregant soybean populations for resistance to Asian rust Estratégias de seleção de populações segregantes de soja para resistência à ferrugem-asiática

Pesquisa Agropecuária Brasileira, 2009
The objective of this work was to identify the best selection strategies for the more promising parental combinations to obtain lines with good resistance to soybean Asian rust (Phakopsora pachyrhizi). Two experiments were carried out in the field during

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

High‐Efficiency and Eco‐Friendly Management of Multiple Fungal Diseases by a Novel Carbon Dots sCDP Delivered RNA Nano‐Pesticides

Plant Biotechnology Journal, EarlyView.
ABSTRACT RNA‐based pesticides represent a transformative approach in agricultural disease management, offering an environmentally sustainable alternative to conventional chemical fungicides. However, key challenges such as rapid RNA degradation in the environment and inefficient uptake hinder widespread adoption.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Sensibilidade de populações de Phakopsora pachyrhizi ao fungicida protioconazol

Summa Phytopathologica, 2020
RESUMO A redução na eficiência de fungicidas sintéticos está associada a seleção de indivíduos que apresentam alterações genéticas que conferem resistência aos ingredientes ativos. A sinalização de variações na frequência de indivíduos resistentes nas populações de fungos pode ser quantificada através da concentração efetiva 50 (CE50).
