Black gram is infested with different categories of weeds. Among broad leaved weeds Parthenium hysterophorus, Phyllanthus niruri, Amaranthus viridis, Celosia argentea, Cleome viscosa, Trianthema portulacastrum; among grassy Echinochloa spp., Setaria glauca, Digera arvensis, Elusine indica, Dectyloctenium aegyptium, Cynodon dactylon and among sedges Cyperus rotundus, Cyperus difformis dominate. Echinochloa colona alone, one of the major weeds in black gram, may reduce the seed yield to the extent of 49-80%. No phytotoxic effects on blackgram in terms of epinasty, hyponasty, necrosis, vein clearing and wilting at 3, 5, 7 and 15 days after application of quizalofop-ethyl @ 37.5 g/ha, fenoxaprop-p-ethyl 100 @ g/ha and thus, found completely safe for the crop and also found no residual effect on soil.
