Efficacy of Trifluralin, Linuron and Acetachlor against Weeds in Mungbean (Vigna radiata)

Two years' (1998 and 1999) field investigation undertaken at CCS Haryana Agricultural University, Hisar, India, revealed that performance of trifluralin 0.75 kg/ha (PPI), linuron 0.75 kg/ha and acetachlor 1.0 kg/ha (pre-emergence) each integrated with one hand weeding at 30 DAS was superior to their alone application against weeds in mungbean. Consequently these treatments were similar to weed free check in respect of yield and yield attributes. There was no additional gain when the treatments of trifluralin 0.75 kg/ha, linuron 0.75 kg/ha and acetachlor 1.0 kg/ha each were superimposed with fenoxaprop 100 g/ha at 35 DAS compared to their alone applications. Weeds competing with the crop throughout the season resulted in 81.5 and 86.4% yield reductions during 1998 and 1999, respectively.
