Wheat, Weed complex, AEF 046360-8% EC , DIC 1468 -14 -22% EC
A field experiment was conducted to evaluate the bio-efficacy of new herbicides AEF 046360-8% EC and DIC 1468-14-22% EC alone and in combination at different doses against the complex weed complex in wheat crop. Wheat crop was mainly infested with grassy weeds like Avena ludoviciana, Phalaris minor and broad leaf weeds viz., Coronopus didymus, Anagallis arvensis, Melilotus spp. And Chenopodium album. Combined application of AEF 046360-8% EC and DIC 1468-14-22% EC (100+175 g/ha) was found effective against all the weeds as shown by the the lowest weed density of grassy as well as broad leaf weeds. AEF 046360-80% had better control over grassy weeds, whereas, DIC 1468-14-22% EC was found effective against broad leaf weeds. The highest grain yield was obtained with the application of AEF 4630-8% EC+ DIC 1468–14-22% at (100 + 175 g/ha) and was found at par with application of sulfosulfuron and AEF 4630-8% EC + DIC 1468-14-22% EC with their lower doses (80 + 140 g/ha).
