Ensure that herbicide drift does not occur onto lentil crops.
Visual symptoms appear within hours of application with spots of dead tissue on otherwise healthy leaves. There may also be wilting and inter-veinal yellowing followed by browning and blackening of the leaf edges.
Plants shrivel up within four days of application if damage is severe.
Signs are often worse on one side of the plant or stem.
Effects disappear as new growth develops.
