The present study has been carried out to investigate the effects of the herbicide Fusilade (Fluazifop-p-butyl) on root and shoot growth of lentil seedlings. Four different doses of Fusilade (0.25%, 0.5%, 1% and 1.5%) were used in (Fluazifop-p-butyl) Lens culinaris seeds and leaves. The obtained results indicate that shoot growth and lateral root growth was reduced in Fusilade treated groups. Leaf deformations like chlorosis, curling, expansion and asymmetry was observed in Fusilade treated leaves. It was also seen that leaf treatment was more sensitive than seed treatment against the effects of herbicide Fusilade
