What is it?

Weed killers are pesticides that do what? Kill weeds! A weed is a plant that is seen as useless or harmful and growing where it is not wanted. For example, grass is not a weed if it is growing in your yard. It is a weed if it is growing in your flower or vegetable garden. Plants like crabgrass and dandelions are usually called weeds. Weeds grow quickly and are hardy plants. They can crowd out or cause other plants not to grow well. They can completely take over an entire garden or spread out in your lawn.

Weed killing pesticides come in different forms – sprays, powders, or mixed in with fertilizers. They are also known as herbicides. So how does a weed killing herbicide know what is a weed and what isn't? It doesn't. For example, a herbicide that is formulated or made to kill bushy weeds like poison ivy or poison oak, can also kill other plants, grasses and even trees. That's why it is important to always "Read the Label First".

If weed killers are used around your house, it should be an adult that uses them. But you may see them stored in your garage or shed, or see them being used. Remind your parents to always "Read the Label First" to know how to properly use these products and for safety information.
