RinskorTM active (Dow AgroSciences code number XDE-848; proposed ISO name in review) is a new arylpicolinate herbicide being developed by Dow AgroSciences with global utility in seeded and transplanted rice and other crops. Data from field trials conducted since 2010 have demonstrated that Rinskor has broad-spectrum activity on important grass, sedge, and broadleaf weed species in rice. Common use rates are 5 to 50 g ai ha-1 depending on use pattern and target species. Selectivity in certain crops can be enhanced with the use of herbicide safeners such as cloquintocet-mexyl, isoxadifen-ethyl, cyprosulfamide, or mefenpyr. Key species controlled within defined use patterns include: Echinochloa crus-galli; Echinochloa colonum; Echinochloa oryzicola; Urochloa plantaginea; Urochloa platyphylla; Leptochloa chinensis; Cyperus difformis; Cyperus iria; Cyperus rotundus; Fimbristylis miliacea; Abutilon theophrasti; Aeschynomene spp.; Amaranthus spp.; Ambrosia spp.; Chenopodium album; Conyza spp.; Heteranthera spp.; Ludwigia octovalis; Monochoria vaginalis; Sagittaria trifolia; Sesbania exaltata and Xanthium strumarium. As arylpicolinates are unique auxin chemotypes, Rinskor has demonstrated a unique spectrum of activity and the ability to control ALS, ACCase, propanil, and quinclorac-resistant grass and broadleaf species. Favorable environmental fate, toxicology, and ecotoxicology properties are anticipated for Rinskor. The first registrations of Rinskor are expected in 2017 or 2018.
