Which plant species is susceptible to 2,4-D drift?

Roses are particularly susceptible to 2,4-D drift due to their sensitivity to this herbicide, which is commonly used for controlling broadleaf weeds. 2,4-D functions as a plant growth regulator and can cause significant damage to non-target plants like roses, leading to symptoms such as leaf curling, distortion, and yellowing. This sensitivity is why roses are often referenced in the context of 2,4-D use and drift management.

In contrast, species such as Kentucky Bluegrass, Pampas Grass, and Fescue have a higher tolerance or resistance to 2,4-D. These plants can often withstand certain levels of this herbicide without exhibiting severe negative effects, making them less of a concern when 2,4-D is applied in nearby areas. Understanding the sensitivity of different plant species to herbicides is crucial for effective pest management and to protect valuable ornamental plants like roses from unintended damage.
