EFFECT OF TRALKOXYDIM AND ITS COMBINATION WITH OTHER NEW HERBICIDES ON THE CONTROL OF WEEDS IN WHEAT (TRITICUM-AESTIVUM)

A field experiment was conducted during the winter season of 1991-92 a nd 1992 93 at Hisar. In both the years tralkoxydim or metsulfuron each applied alone at 300 q/ha and 4.0 q/ha significantly reduced the popu lation and dry weight of total weeds compared with the weedy cheek. th eir combination at same rate resulted in the excellent control of weed s like Phalaris minor Retz, Chenopodium album (L.) and Meliotus indica All. Number of tillers/m in the weedy check reduced from 94 to 58 in 1991-92 and from 92 to 62 in 1992-93 compared with weed-free check. Si milarly, the grain yield of wheat in the weedy check ranged from 3,005 to 3,241 kg/ha compared with 4,728 to 5,260 kg/ha in the weed-free ch eck. Tank mixture of tralkoxydim + tribenuron at 200 + 7.5 g/ha, tralk oxydim + metsulfuran at 300 + 4.0 g/ha or traldoxydim + fluroxypyr at 300 + 200 q/ha gave significantly higher grain yield of wheat than wee dy check.
