Herbicides
Definition
Herbicides are chemicals used to eliminate or control unwanted plants, commonly known as weeds, in agriculture and gardening.
Scientific / Technical Definition
Herbicides, also known as weedkillers, are substances used to control or terminate plant growth, particularly unwanted plants. They function by interfering with biological processes vital to the plants, such as photosynthesis, enzyme function, or cell division, ultimately leading to the plant's death.
Benefits
- Help maintain crop yields by reducing weed competition
- Decrease manual labor required for weed control
- Facilitate the growth of desirable plants by minimizing competition
Examples
- Glyphosate is a commonly used broad-spectrum herbicide.
- Atrazine is used to prevent pre- and post-emergence broadleaf weeds in crops.
- 2,4-D is a selective herbicide used in environments requiring non-grass plant removal.
Additional Information
- Known issues: Extended herbicide use can lead to herbicide resistance among weed populations, which makes them harder to control over time. Additionally, there are concerns regarding the impact of certain herbicides on human health and the environment.
