What is a key property of Ester herbicides?

Ester herbicides are characterized by their improved ability to be absorbed by plant tissues, making them particularly effective for certain applications. This enhanced absorption is due to their chemical structure, which allows them to penetrate plant cuticles more easily. As a result, ester formulations tend to provide quicker results in weed control, as the active ingredient can reach the site of action within the plant more effectively.

This property is particularly advantageous in many turf management situations, where rapid results are often desired after application. The other answer choices do not accurately represent key properties of ester herbicides. While some formulations may be more toxic, this is not a defining characteristic of ester herbicides overall. Similarly, their performance is not necessarily tied to cooler temperatures, as they can lose effectiveness in such conditions. Additionally, ester herbicides tend to be more volatile compared to amine formulations, which can make them less suitable for certain applications where drift is a concern.
