Abstract

A study was conducted to evaluate the effect of imazosulfuron, halosulfuron, and trifloxysulfuron POST-directed on six fresh-market tomato varieties. Injury 7 d after treatment (DAT) was 3% or less from all treatments, and no injury was observed 28 DAT. Imazosulfuron, halosulfuron, and trifloxysulfuron did not reduce yield relative to the nontreated check. There was no detectable herbicide effect on fruit shape and earliness. Data suggest that imazosulfuron, halosulfuron, and trifloxysulfuron can be applied POST-directed without negatively affecting yield or quality of several fresh-market tomato varieties.

Un estudio fue realizado para evaluar el efecto de imazosulfuron, halosulfuron, y trifloxysulfuron post-dirigido en seis variedades de tomate fresco para el mercado. El daño 7 días posteriores a la aplicación de los tratamientos (DAT) fue 3% o menos en todos los tratamientos y no fue observado ningún daño 28 DAT. El imazosulfuron, el halosulfuron, y el trifloxysulfuron no disminuyeron la producción en relación al testigo no tratado. No se detectó efecto de los herbicidas en la forma del fruto y su precocidad. La información sugiere que el imazosulfuron, el halosulfuron, y el trifloxysulfuron pueden ser aplicados de forma post-dirigida sin afectar negativamente el rendimiento ni la calidad de las distintas variedades de tomates frescos para el mercado.
