Wheat, AEF+DIC, grassy, broadleaf weeds

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 post-emergence (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.
