%X The effects of 2,4-D on tobacco at various stages of growth were investigated. Symptoms of damage were recorded and illustrated. The herbicide had no obvious effect on mature plants at any concentration used, but it caused considerable damage to plants at other phases of growth at moderate and high concentrations. A chemical method was developed for accurate determination of 2,4-D residues in tobacco. Investigation of the herbicide residues in irrigation water was necessary following the discovery of 2,4-D residues in control plants.
