  Evaluation of Mesotrione in Combination with Innovative Herbicides within Cranberry Production

Abstract: Sedge species, including black bulrush (Scirpus atrocinctus), are problematic for producers as they survive well in cranberry production. Mesotrione recently received registration in Canada for the control of labelled weeds within established cranberry beds. Producers may be interested in combining mesotrione with other herbicides to improve the spectrum of weed control and reduce application costs. A trial was initiated near Saint Charles, New Brunswick in an established cranberry bed to evaluate mesotrione alone and in combination with innovative herbicides. Black bulrush control from mesotrione, nicosulfuron/rimsulfuron and chlorimuron–ethyl alone was high, with minor suppression shown with quinclorac and no control from clethodim. There was no significant difference by the final rating date between nicosulfuron/rimsulfuron, chlorimuron–ethyl and clethodim applied in tank mix with mesotrione as compared to mesotrione applied alone. A significant reduction was noted within the quinclorac/mesotrione tank mix as compared to mesotrione applied alone.
