Abstract

Three soil applied herbicides such as fluchloralin, trifluralin and pendimethalin applied alone and integrated with hand weeding were compared with controls in a field experiment during rainy seasons of 1992 and 1993. Higher rate ofall the herbicides gave better control of weeds than lower rates. All the herbicides provided effective control of carpetweed (Trianthema portulacastrum) and hazardana (Phyllanthus nirun) during both the years. All the herbicides failed to control yellow nutsedge (Cyperus rotundus). Integration of reduced rate of each herbicide (1.0 kg/ha) with one, hand weeding at 60 days after sowing reduced the density and dry matter of weeds more than single application of these herbicides at higher rates. On the other hand integration of herbicide and hand weeding resulted in more or less similar yield attributes and seed yield of pigeonpea when compared with weed free check and hand weeded twice treatments in both the years. All weed control treatments resulted in significantly higher pigeonpea yield than unweeded check.
