POSTEMERGENCE Meaning and
Definition
-
Postemergence is an agricultural term that refers to the application of herbicides or other control measures after the emergence of weeds or other unwanted plants in a field or garden. It denotes the actions and treatments taken to control or eliminate these plants once they have already sprouted and grown.
In farming practices, postemergence treatments are typically performed to manage and eradicate weeds that have survived preemergence herbicide applications or have germinated after planting. These treatments involve the targeted application of herbicides directly onto the plant foliage or stems, with the objective of interrupting their growth or causing their death.
Postemergence herbicides are specifically formulated to control established plants and may be selective or non-selective in their action. Selective herbicides target specific types of plants while minimizing damage to desirable crops or vegetation. Non-selective herbicides, on the other hand, have a broader spectrum of activity and can destroy most plants they come into contact with.
Postemergence control methods are widely used in agriculture to supplement preemergence strategies and combat the presence of unwanted plants that sprout and compete with cultivated crops for resources. By tackling these vegetation issues after they have already begun growing, postemergence treatments offer an effective means of managing weed populations and enhancing agricultural productivity.
Etymology of POSTEMERGENCE
The word "postemergence" is derived from a combination of two words: "post" and "emergence".
1. "Post" comes from the Latin word "post", meaning "after" or "behind". It is commonly used as a prefix in English to indicate something that occurs after or follows a specific event or state.
2. "Emergence" comes from the Latin word "emergere", which means "to arise" or "to come forth". It refers to the process of something becoming visible, apparent, or recognizable.
Therefore, when combined, the word "postemergence" refers to something that occurs or is relevant after the emergence or appearance of a particular event, situation, or condition.
