Competitiveness of ALS inhibitors resistant and susceptible biotypes of Greater Beggarticks (Bidens subalternans) Competitividade de biótipos de Picão-Preto (Bidens subalternans) Resistente e euscetível aos inibidores da ALS

Planta Daninha, 2011
The continuous use of ALS-inhibiting herbicides has led to the evolution of herbicide-resistant weeds worldwide. Greater beggarticks is one of the most troublesome weeds found in the soybean production system in Brazil.

Resistência de Bidens subalternans aos herbicidas inibidores da enzima acetolactato sintase utilizados na cultura da soja Resistance of Bidens subalternans to the acetolactate synthase inhibitor herbicides used in soybean crop

Planta Daninha, 2002
O uso contínuo e prolongado de produtos com o mesmo mecanismo de ação pode provocar a manifestação de biótipos resistentes. Para verificar possíveis novos casos de resistência, bem como alternativas para prevenção e manejo, foram coletadas sementes de ...

Influence of Uroclhoa brizantha cv. Marandu phytomass in the control of Bidens subalternans under dystrophic yellow latossol

African Journal of Agricultural Research Vol Pp, 2015
The objective of this work was to evaluate the interference resulting from the use of different phytomass quantities of Uroclhoa brizantha cv. Marandu and the management of straw to control beggar-ticks (Bidens subalternans). The experiment was performed under greenhouse from May to August, 2014, using a randomized block experimental design with four ...

EFFECTIVENESS OF TERBUTHYLAZINE AND ATRAZINE IN THE CONTROL OF Bidens subalternans IN THREE STAGES OF APPLICATION

Nativa
The objective was to evaluate the efficacy of terbuthylazine and atrazine doses in controlling greater beggarticks (Bidens subalternans) that are resistant to ALS inhibitors and exhibit resistance to atrazine, at three application times. The treatments were arranged in a 2x6 factorial design, in which two herbicides were used: atrazine and ...

Contrasting plant ecological benefits endowed by naturally occurring EPSPS resistance mutations under glyphosate selection

Evolutionary Applications, Volume 14, Issue 6, Page 1635-1645, June 2021., 2021
Abstract Concurrent natural evolution of glyphosate resistance single‐ and double‐point EPSPS mutations in weed species provides an opportunity for the estimation of resistance fitness benefits and prediction of equilibrium resistance frequencies in environments under glyphosate selection.

Identification and Mapping of Cross-Resistance Patterns to ALS-Inhibitors in Greater Beggarticks (Bidens spp.) [PDF]

Planta Daninha, 2019
: Greater beggarticks (Bidens pilosa and Bidens subalternans) biotypes have been under selection pressure of ALS-inhibitors since early 90’s in Brazil. The objectives of this work were to investigate whether there are different cross-resistance patterns ...

Resistência de plantas daninhas aos herbicidas inibidores da ALS na cultura da soja (Glycine max) Weed resistance to ALS - inhibiting herbicides in soybean (Glycine max) crop

Planta Daninha, 2000
As plantas daninhas Bidens pilosa/Bidens subalternans (picão-preto) e Amaranthus quitensis (caruru) são controladas na cultura da soja por diversos herbicidas, sendo os inibidores da acetolactato sintase (ALS) os mais utilizados pelos sojicultores. O uso
