An Overview On Weed Killers

Also known as herbicides, weed killers are chemicals applied to control and eliminate unwanted vegetation like weeds and crabgrass. They can inhibit a weed’s cell division or photosynthesis and disrupt its amino acid production.

Other weed killers mimic natural plant growth hormones and cause deformities. You can spray them onto foliage or soils, and one of the best-known weed killer chemicals is glyphosate. This chemical is an amino acid disrupter with a broad spectrum and low toxicity to animals.

Chemical-based weed killers are more common, but natural herbicides can also work pretty well. Some contain citrus oil and vinegar, which causes weeds to dry out, curl up and die. These are good for people who have pets and small children, but the chemical counterparts can be just as safe when applied according to the label directions. The best ones work in 24 hours or less, so it’s best to keep everyone away from the area for the time specified on the product label.

Some retailers sell liquid herbicides in smaller, ready-to-use containers or in concentrate form; these methods can be cost-saving. You must apply granular weed control products with spreaders, which is easy to do if you need to cover a whole lawn.

Pre-emergent weed killers are not referred to as herbicides; they are weed preventers and attack sprouting weed seedlings before they emerge from the ground. You’ll want to use these in the spring and fall. Herbicides, which are known as post-emergent weed killers, control existing weeds instead.

The Weed Killer Buying Guide

  • Weedkiller and preventer granules can be combined with dry fertilizer and spread simultaneously. This method is an excellent way to kill two birds (and many weeds) with one stone.
  • Be careful with broad-spectrum weed killers because they are non-selective and may kill desirable plants and grasses. The labels usually specify which weeds the products work on.
  • If you are overrun with a tough weed like nutsedge, choose a selective weed killer that lists the particular one on the label.
  • Herbicides don’t have expiration dates and can last for up to five years. Shake well before using and follow the label directions carefully.
  • Keep the weed container lid on tightly and away from high heat, sunlight, children and pets.
