“…Injury from halosulfuron carryover to rotational crops has occurred as a result of its variable soil behavior (Grey et al, 2007b). Although halosulfuron has been extensively evaluated in annual crops for tolerance and carryover (Dittmar et al, 2008;Haar et al, 2002;Jennings, 2010;Sikkema et al, 2008;Webster et al, 2003), little information about pecan tree tolerance has been reported.…”

Pecan production in the southeastern United States has increased because of the worldwide demand for the nuts of this tree. Information about the effects of the residual herbicides indaziflam and halosulfuron on newly planted pecan trees was evaluated over time for 4 years on sandy loam soils. After winter pecan tree planting, multiple spring or autumn herbicide applications were applied to the same pecan trees in different experiments in consecutive years. Visual injury, height, and caliper diameter measurements were taken up to six times during the growing season. Regression analysis of treatments over time indicated no differences in pecan tree growth for indaziflam at 73 or 146 g a.i./ha or halosulfuron at 35 g a.i./ha applied up to six times in 3 years, or for indaziflam at 37, 73, or 146 g a.i./ha applied up to five times in 3 years, as compared with nontreated controls. This information will benefit growers seeking viable weed control options when establishing new groves to meet the increased worldwide demand for pecan nuts.

“…This difference appears to be primarily due to a reduction in the yield of extra large fruit; there were no differences in yield in the medium and large grade. The yield reduction was unexpected, as previous research has shown that halosulfuron is safe for use in fresh-market tomato (Dittmar et al 2012; Jennings 2010), but crop tolerance has been shown to vary with cultivar (Mohseni-Moghadam and Doohan 2017). The halosulfuron label specifically instructs against applying following bloom unless crop shields are in place or the spray is directed away from the plant (Anonymous 2015).…”

“…Unfortunately, they only tend to provide inconsistent (Boyd 2015) and short-term nutsedge suppression (Dittmar 2013). POST-directed herbicides such as imazosulfuron, halosulfuron, and trifloxysulfuron can be safely applied to tomato (Jennings 2010). In Florida, halosulfuron is the most common POST-directed herbicide applied for nutsedge control in tomato, but crop tolerance can vary with cultivar (Mohseni-Moghadam and Doohan 2017).…”

Purple nutsedge is difficult to control in vegetable plasticulture due to its ability to penetrate the plastic mulch. Experiments were conducted in Spring 2011 and 2012 at the Plant Science Research and Education Center in Citra, Florida, and in Spring and Fall 2013 at the Gulf Coast Research and Education Center in Balm, Florida. The objective was to determine tomato (cv. Amelia, Charger, and Florida 47) tolerance and purple nutsedge response to herbicides and herbicide tank-mixes applied POST-directed to base of tomato. Chlorimuron-ethyl, flazasulfuron, fomesafen, halosulfuron, imazosulfuron, rimsulfuron, nicosulfuron, and trifloxysulfuron applied POST-directed to the base of the crop did not cause crop damage. Halosulfuron or tank-mixes that contained halosulfuron tended to provide the greatest nutsedge suppression in all experiments. Halosulfuron or nicosulfuron+rimsulfuron applications when tomato (cv. Charger) were flowering reduced marketable yields by 22-28% compared to the nontreated control. No yield reductions occurred with Florida 47 or Amelia cultivars. Flazasulfuron provided similar purple nutsedge suppression to halosulfuron and did not damage tomato. Tank-mixes that contained halosulfuron tended not to provide any added benefit over halosulfuron alone. This research identified herbicides that are safe for use as a POST-directed application in tomato. Additional research is needed to evaluate efficacy of these herbicides on broadleaf weeds.

“…En Chile, buscando alternativas para la rotación de Metribuzina, se ha evaluado el uso de halosulfuron-metil, el cual causa daños temporales en follaje, con posterior recuperación a los 21 días después de aplicación (Ormeño et al, 2002). Jennings (2010) evaluó sulfonilureas en Carolina del Norte, encontrando que imazasulfuron, halosulfuron y trifloxisulfuron no presentaban efectos negativos sobre la producción, a diferencia de lo comentado por Dittmar et al (2012) quienes evaluando los mismos herbicidas en postrasplante reportan daños en las plantas de cultivo entre 20% y 50% afectando el crecimiento, tras la aplicación en postrasplante de estas moléculas.…”

Se llevó a cabo un experimento en invernadero y otro en condiciones de campo, evaluando el comportamiento de Ácidos hidroxicarboxílicos (AHC), como biorreguladores orgánicos en plantas de tomate tratadas con aplicación foliar de Metsulfuron-metil y Metribuzina a dosis comercial (X) y sobredosis (2X). En la etapa de invernadero, se evaluó la eficiencia cuántica (Fv/Fm), contenido de clorofilas, conductancia estomática e intercambio de CO2; en campo, se caracterizó el desarrollo foliar, crecimiento de raíces, TAN, TRC y rendimiento del cultivo bajo un sistema de producción convencional. La aplicación de Metsulfuron-metil (X y 2X) no alteró significativamente el contenido de clorofilas ni la conductancia estomática; sin embargo, disminuyó en 80% y 100% la eficiencia cuántica e intercambio de CO2 respectivamente, lo cual fue mitigado por la aplicación de AHC. Los AHC también evitaron la disminución del crecimiento de raíces y recuperaron la TAN y TRC durante el primer mes de evaluación, propiciando mayor llenado de fruto. Metribuzina afectó significativamente el intercambio de CO2 durante los primeros 15 dda; la aplicación en sobredosis afectó la eficiencia cuántica a partir de 7dda y causó defoliación a partir de 30 dda, lo que estuvo ligado con un descenso del 20% en producción. Los AHC sopesaron el estrés causado por Metribuzina y lograron valores similares a los alcanzados por las plantas testigo en todas las variables analizadas.
