Rinskor™ active (ISO name applied for) is a new postemergence herbicide being developed by Dow AgroSciences for use in global seeded and transplanted rice markets.  Rinskor is the second member of a new arylpicolinate class of herbicides that exhibits broad-spectrum herbicidal activity on select grass, sedge, and broadleaf weed species.  Mid-South U.S. rice weeds susceptible to Rinskor include:  Echinochloa crus-galli, Echinochloa colona, Urochloa platyphylla, Leptochloa panicoides, Cyperus iria, Cyperus esculentus, Sesbania herbacea, Aeschynomene spp., Conyza spp., Amaranthus spp., Ambrosia spp., Alteranthera philoxeroides, Eclipta prostrata, Heteranthera spp. and Sagittaria spp.  The unique weed spectrum of Rinskor is complemented by its ability to control ALS-, ACCase-, propanil-, and quinclorac-resistant species. Grass and sedge weeds treated with Rinskor exhibit swelling and necrosis of the crown while broadleaf weeds treated with Rinskor exhibit an epinastic response. Rinskor exhibits excellent safety to both medium-grain and long-grain rice varieties and hybrids within conventional and Clearfield® rice systems. The first registrations of Rinskor are expected in 2017 or 2018.
