Genetic diversity and population structure of ALS‐resistant Amaranthus hybridus across Brazil's primary soybean‐growing regions

Pest Management Science, Volume 81, Issue 9, Page 5394-5402, September 2025.
We identified two distinct target‐site mutations, Asp‐376‐Glu and Trp‐574‐Leu, that confer resistance to acetolactate synthase inhibitors in Amaranthus hybridus populations across Brazil's soybean‐growing regions. These findings suggest multiple independent origins of resistance, with its spread primarily driven by local herbicide selection pressure ...

Multilocus Sequence Typing of “Candidatus Phytoplasma Solani” and Detection of RNA Viruses Infecting Cucurbits in the Marmara Region, Türkiye

Plant Pathology, Volume 74, Issue 6, Page 1905-1914, August 2025.
This study provides the first multilocus genetic characterisation of “Candidatus Phytoplasma solani” strains infecting cucurbits. ABSTRACT The stolbur disease associated with “Candidatus Phytoplasma solani” (CaPsol) is very common in Europe and the Mediterranean regions and adversely affects perennial or annual plants but is rarely reported on ...

CONTROLE QUIMICO DE CONYZA BONARIENSIS EM DESSECAÇÃO

JOURNAL OF NEOTROPICAL AGRICULTURE, 2014
A buva (Conyza bonariensis) é uma das principais plantas infestantes no agroecossistema brasileiro, demandando novas alternativas de manejo a cada safra. O objetivo desse trabalho foi avaliar o desempenho de diferentes programas de aplicação de herbicidas na dessecação de área experimental infestada com buva. O experimento foi conduzido em condições de

Synergism of the glyphosate and saflufenacil combination for controlling hairy fleabane

Pesquisa Agropecuária Tropical, 2015
In Brazil, hairy fleabane stands out among the main weeds of soybean crops, due to its aggressiveness and resistance to glyphosate. Thus, to avoid the selection of resistant populations to the glyphosate herbicide, the use of other herbicides has become ...

Karyotypic studies and morphological analysis of some reproductive features in five species of Conyza (Astereae: Asteraceae) from Northeastern Argentina Estudios cariotípicos y análisis morfológico de algunos caracteres reproductivos en cinco especies de Conyza (Astereae: Asteraceae) del Noreste de Argentina

Boletín de la Sociedad Argentina de Botánica, 2005
The cosmopolitan genus Conyza Less. comprises about 100 species, 22 of which occur in Argentina. Current taxonomic treatments, largely based on exomorphological characters, are insufficient to characterize and circumscribe some of their polymorphic ...

Differential susceptibility and resistance to glyphosate in annual ryegrass and wavy-leaved fleabane [PDF]

Communications in Plant Sciences, 2014
Annual ryegrass (Lolium multiflorum) and wavy-leaved fleabane (Conyza bonariensis) were tested, aiming to investigate the dose-response of biotypes of both species to glyphosate. Glyphosate herbicide at doses varying from 0 up to 1.440 g e.a.
