What type of damage can be caused by herbicides?

• A. Increased photosynthesis
• B. Curling and cupping of foliage
• C. Enhanced growth
• D. Root rot

Answer: (B)

Herbicides can cause various physiological damage to plants, and one of the most common symptoms observed is the curling and cupping of foliage. This response typically occurs when a herbicide acts as a growth regulator or disruptor of normal plant growth processes. Certain herbicides mimic natural plant hormones, leading to abnormal growth patterns, which manifest as distorted leaves that curl or cup. These symptoms indicate that the herbicide is interfering with the metabolic processes essential for the plant's health and development. This distortion can also make plants more vulnerable to environmental stress and diseases, causing further complications in plant management and health. In contrast, options that suggest increased photosynthesis, enhanced growth, or root rot do not accurately reflect the common effects of herbicide exposure. Herbicides are primarily designed to inhibit growth in unwanted plants and generally do not enhance normal physiological processes in desirable plants.
