Performance of Ready Mix Formulation of Fenoxaprop+Metribuzin for the Control of Grass and Broadleaf Weeds in Wheat

An experiment was conducted for three years at the Research Farm of Department of Agronomy, Punjab Agricultural University, Ludhiana during rabi seasons of 2007–08 to 2009–10. The experimental field was heavily infested with Phalaris minor and broadleaf weeds. A new herbicide i. e. AEF 04 6360-8%+DIC 1468–14%-22% EC (fenoxaprop-P-ethyl+metribuzin) was applied at 165, 220, 275, 330 and 550 g/ha as postemergence (30–35 DAS). The results of three years revealed that application of this herbicide at 275 and 330 g/ha provided effective control of P. minor and broadleaf weeds in wheat crop and were found statistically at par with Atlantis 3.6 WDG (mesosulfuron 3.0%+iodosulfuron 0.6% at 12+2.24 g) on dry matter accumulation by P. minor and broadleaf weeds. On an average of three years, post-emergence application of AEF 046360- 8%+DIC 1468–14%-22% EC at 275 and 330 g/ha as well as Atlantis 3.6 WDG at 14.4 g/ha increased wheat grain yield by 58.8, 64.2 and 67.3% as compared to unweeded (control) treatment, respectively.
