Weed Killers
For many years, chemical management using herbicides or weed killers has been a key strategy for controlling weeds in crops and residential landscapes. As the name implies, these products are designed to kill unwanted plants. They can be applied as a spray or as a soil drench. However, some of those chemicals pose human health risks, including cancer and birth defects. More recently, there have been calls for more organic practices because they do not harm people.
Weedkillers are chemical-based liquids that are specifically engineered to target different types of weed in the best way possible. Whatever the weeding job that you are trying to tackle, there is a weedkiller that is matched to that job and will do exactly what you need.”

How safe are weed killers?
The U.S. Environmental Protection Agency regulates the use of herbicides by requiring them to undergo testing and approval before being available for sale. Most commonly used herbicides are classified as “pesticides” under EPA’s pesticide regulation program. The agency tests the safety of pesticides before allowing their registration.
If a pesticide is registered, it means that it has been tested and found to be safe enough to be sold to consumers and farmers. Pesticide manufacturers must report all adverse effects from using their product. This reporting includes any damage caused by applying to lawns, gardens, vegetable fields, livestock rangelands, forests, golf courses, parks, playgrounds and other areas where children play.
What are the main types of weed killers?
There are four broad categories of herbicide:
- Contact herbicides
- Systemic herbicides
- Pre-emergence herbicides and
- Post-emergence herbicide.
Contact herbicides are sprayed on foliage and can be either selective or nonselective. Selective is defined as killing only specific species at the time of application but having no effect on desirable plants, while nonselective kills both undesirable plants and desired ones, usually at times when they should be growing. Systemic herbicides move through plant tissues and may stay active even after applications are stopped. Pre-emergence herbicidal activity occurs before seeds germinate, while post-emergent controls occur after seeds sprout.
What are the benefits of using weed killers?
Herbicides are effective against annual weeds . They also work well in greenhouses and commercial nurseries. These products take advantage of what gardeners call “the window of opportunity.” That is, the best time for applying a weed killer is just before new growth starts. Herbicides stop seeds from forming, so they can’t produce offspring.
Why don’t we see more biodegradable weed killers?
It’s true that most weed killers are toxic to wildlife. But they’re also toxic to humans! And they often remain potent long after they’ve dried up. For example, many popular herbicides can easily leach into water sources like lakes, streams and groundwater.
Is weed killer safe for pets?
Pets, especially dogs, can accidentally consume weed-killing materials if they’re left lying around outdoors. Keep your pet away from chemicals and keep them out of places where they could ingest them. If you suspect that your dog has ingested a harmful substance, contact a veterinarian who specializes in poisons and toxins.
Where does weed killer go once it dries up?
Garden centers sell treated soils and mulches. Lawn fertilizer contains weed killers. Weed killers can also wash off in rainwater runoff and end up in rivers and lakes. Soil treated with weed killers will eventually degrade naturally. It breaks down over time.
How do I know which herbicide is right for me?
There are different levels of toxicity among herbicides. Some kill broadleaf plants better than others. Each type is listed with its toxicity level on the product label — for example, “toxic to aquatic life,” “harmful to fish,” or “highly toxic to mammals.” For information about the toxicity of common weed killers, click here.
Do I need to read labels carefully?
You’ll find warnings on every label. Read the directions carefully. Follow them exactly. Don’t apply too much, especially to sensitive areas such as flowers or vegetables.
Always wear gloves, goggles and protective clothing. Wash thoroughly after use, and let the area dry completely before going inside. Do this because some weed killers have ingredients that can cause skin irritation. Also look for signs of burning eyes, nosebleeds, nausea, headaches, dizziness and vomiting — these can indicate exposure to an irritant.
Can I spray my whole yard with weed killer?
No. You must always follow the directions exactly. Too little won’t get rid of the weeds; too much might harm your plants.
