Phytotoxicity refers to the toxic effects of chemicals, such as pesticides or herbicides, on plants. The symptoms associated with phytotoxicity commonly include browning of leaves, leaf curling, and stunted growth. These symptoms occur due to the stress induced by chemical exposure, disrupting the plant's physiological processes.

Browning of leaves often indicates cell death or damage, which is a direct result of phytotoxic effects. Leaf curling may occur as the plant tries to protect itself from the toxins or due to interference with the plant's hormonal balance. Stunted growth reflects the overall adverse impact on the plant's development and health due to the stress of phytotoxic exposure.

On the other hand, holes in leaves are typically signs of damage caused by pests rather than a direct result of chemical toxicity. This symptom points more towards physical damage or the action of herbivorous insects, which create holes as they feed on the plant tissue. Therefore, it is not a typical symptom associated with phytotoxicity.
