Herbicide injury may include which of the following symptoms?

• A. Distortion Of The Leaves
• B. Scorching Of The Leaves
• C. Branch Dieback
• D. All Of The Above

Answer: (D)

Herbicide injury can appear in several ways because different chemicals and exposure routes affect plant tissues differently. Distortion of leaves happens when growth-regulator herbicides interfere with how leaves expand, causing curling, twisting, or cupping. Scorching or browning of leaf tissue occurs when the chemical damages the leaf surface or underlying cells, leading to bronze or necrotic spots. Dieback of branches can occur if the injury reaches woody tissues or disrupts the vascular system, reducing vigor and causing terminal or lateral twigs to die back. Because these symptoms can all result from herbicide exposure, the best choice is that all of the above can occur. Drift, misapplication, or uptake by non-target plants can produce these effects.
