Which symptom is commonly associated with herbicide injury?

Leaf distortion and chlorosis are commonly associated symptoms of herbicide injury in plants. When a plant is exposed to herbicides, such as growth regulators that mimic natural plant hormones, it may exhibit abnormal growth patterns. This can lead to the twisting, curling, or distortion of leaves, which is often accompanied by chlorosis, a condition where leaves turn yellow due to insufficient chlorophyll. These changes occur because herbicides disrupt the normal physiological processes within the plant, directly impacting its growth and development.

While wilting of leaves and stunted plants can be symptoms of various plant stressors, including water stress or nutrient deficiencies, they are not as specifically indicative of herbicide damage as leaf distortion and chlorosis. Similarly, excessive root growth is generally not associated with herbicide injury; it tends to relate more to soil conditions or other types of growth stimulators. Therefore, leaf distortion and chlorosis provide a clearer and more specific indication of herbicide impact on plants.
