Effect of Broad Leaf Herbicides Alone and in Combination with Chlortoluron on Weed Control in Wheat

Field experiments were conducted during winter seasons of 1991–92 and 1992–93 at CCS Haryana Agricultural University, Hisar. During both the years, tribenuron at 15 g/ha, f1uroxypyr at 300 g/ha and 2,4-D at 500 g/ha alone reduced the population of Chenopodium album and Lathyrus aphaca at 60 and 90 days after sowing over weedy check. Tank mixture of fluroxypyr+chlortoluronat 150+750 g/ha or 2,4-D+chlortoluron at 500+750g/ha or tribenuron+chIortoluron at 10+750 g/ha controlled grassy and broad leaf weeds significantly during both the years resulting in higher grain yield of wheat.
