Which method helps protect ornamental plants from herbicide injury?

• A. Use selective herbicide
• B. Apply higher than recommended rates
• C. Apply when volatilization is likely
• D. Apply inside drip line of ornamentals

Answer: (A)

The main idea is to protect ornamentals by using a herbicide that will target weeds without harming the plants themselves. A selective herbicide is designed to control specific weeds while being safe for many ornamental species when used exactly as labeled. By choosing a product that has documented tolerance for ornamentals, you minimize the risk of injury to the plants you’re trying to protect. Other approaches raise risk or are not appropriate near ornamentals. Applying more than the labeled rate increases phytotoxicity and can injure ornamentals. Applying when volatilization is likely can cause drift and vapor injury to nearby plants. Applying within the drip line of ornamentals can expose the roots and foliage to chemical uptake, increasing the chance of damage unless the label explicitly allows it.
