Ready mix of pinoxaden and clodinafop-propargyl for control of Phalaris minor in wheat and its residual effects on succeeding rice crop

A field experiment to evaluate the efficacy of a pre-mix herbicide pinoxaden 2.53% + clodinafop 2.53% w/w (Traxos 5% EC) against grassy weed Phalaris minor in wheat was conducted during winter season 2011–12 and 2012–13 at CCS Haryana Agricultural University, Regional Research Station, Karnal. Density and dry weight of P minor under pinoxaden + clodinafop 60 g/ha was at par to pinoxaden 50 g/ha but lower than clodinafop 60 g/ha and fenoxaprop 120 g/ha. However, the differences with clodinafop in respect of dry weight of P. minor were not significant. Pinoxaden + clodinafop 60 g/ha provided control of P minor as good as weed free check, and resulted in higher number of effective tillers than its lower dose (40 g/ha), fenoxaprop 120 g/ha and weedy check. This ready mix provided grain yield of wheat similar to pinoxaden 50 g/ha, clodinafop 60 g/ha and weed free check but higher than fenoxaprop 120 g/ha during both the years, and there was no phyto-toxicity on wheat. There was also no phytotoxicity of pinoxaden + clodinafop up to 120 g/ha on succeeding rice crop.
