Background and aims: Commelina erecta and Eutsachys retusa are two perennial weeds, which show high resprouting after glyphosate application. This behavior represents a serious problem for weed management. The purpose of this study was to characterize the bud bank of both species and to assess their response to glyphosate application.
M&M: We analyzed 120 reproductive shoots of C. erecta, and 80 reproductive shoots of E. retusa, at 30- and 60-days post- herbicide application. The doses applied to C. erecta were 0 (control), 1.200 and 2.400 g a.i. ha -1 , and to E. retusa were 0 (control), 480 and 1200 g a.i. ha -1 .
Results: We found that both species presented active buds in approximately 50% of their nodes, even after herbicide application. Bud bank dynamics changed in both weeds after herbicide application, and therefore their growth pattern. The activation of originally inhibited buds allowed weeds to regrow and survive after glyphosate application altering their architecture.
Conclusions: The bud bank plays an important role in glyphosate tolerance in both weeds. The resprouting capacity in both species was similar for any dose of glyphosate applied. Therefore, an alternative control strategy based on the increase of the dose of herbicide would not be a successful alternative for the management of these weeds. The interruption of the storage of reserves in the rhizome system and the reduction of the number of buds would be key to effective long-term management of these and other perennial weeds in no tillage cropping system. |

Dellaferrera, Ignacio M. Alesso, Carlos A. Vegetti, Abelardo C. Perreta, Mariel G. Commelina erecta Eustachys retusa regeneration weeds herbicide Commelina erecta Eustachys retusa herbicida, malezas regeneración Background and aims: Commelina erecta and Eutsachys retusa are two perennial weeds, which show high resprouting after glyphosate application.

Introducción y objetivos: Commelina erecta y Eutsachys retusa son malezas perennes tolerantes a glifosato. El propósito de este estudio fue caracterizar el banco de yemas de ambas especies y evaluar su respuesta a la aplicación de glifosato. M&M: Se analizaron yemas de 120 ejes reproductivos de C. erecta y 80 ejes reproductivos de E. retusa, a los 30 y 60 días después de la aplicación del herbicida. Las dosis empleadas en C. erecta fueron 0 (control), 1.200 y 2.400 g a.i. ha -1 y en E. retusa fueron 0 (control), 480 y 1200 g a.i. ha -1. Resultados: Ambas especies presentaron yemas activas en aproximadamente el 50% de los nudos, incluso después de la aplicación del herbicida. Ambas malezas alteraron la dinámica del banco de yemas y su patrón de crecimiento post-aplicación del herbicida. Es decir, la activación de yemas originalmente inhibidas permitió que ambas malezas rebroten y sobrevivan, alterando su arquitectura. Conclusiones: El banco de yemas juega un papel importante en la tolerancia a Glifosato en ambas malezas. En ambas especies, la capacidad de rebrote fue similar en cualquiera de las dosis de glifosato aplicadas; por lo tanto, una estrategia de control que aumente la dosis de herbicida no sería una alternativa exitosa para el manejo de estas malezas. La interrupción del almacenamiento de reservas en el sistema de rizomas y la reducción de la cantidad de yemas, serían factores claves para un manejo efectivo a largo plazo de estas y otras malezas perennes, en un sistema de labranza cero.
