What harm can total vegetation control products cause when used near landscapes?

• A. They can injure trees and shrubs if their roots lie under the treated soil, or if the product moves offsite into their root zone.
• B. They only affect annual grasses.
• C. They improve soil drainage and root structure.
• D. They evaporate quickly with no residue.

Answer: (A)

Non-selective total vegetation control products can harm landscape plants because they don’t discriminate between target weeds and desirable plants. If these products are used near lawns, borders, or other landscape plantings, the chemical can reach the root zones of trees and shrubs. Roots extend well beyond the visible canopy, and the product can move through soil water, leaching, or runoff, or be taken up directly by roots that lie under the treated soil. Once absorbed by the roots, the herbicide can cause injury to the trees and shrubs, leading to growth problems, leaf damage, or dieback. The other statements don’t fit the reality of how these products interact with landscapes. They don’t only affect annual grasses; they can affect perennials and woody plants too. They don’t generally improve soil drainage or root structure, and they don’t simply evaporate with no residue—residual activity and root uptake are real concerns.
