Swimming Pool Glossary: Herbicide

If you own a pool, you may find yourself needing a good herbicide. Herbicides are chemcials that prevent and kill unwanted weeds or algae. Simazine is one of the more commonly used herbicides, but it can no longer be bought in the United States.

Selective vs. Non-Selective Herbicides
There are two main types of herbicides: selective and non-selective. A selective herbicide only works effectively on a certain type of plant. Non-selective herbicides are much more useful against a variety of plants, and can often destroy a broad number of them. Herbicides belong to the pesticide family, however, you may sometimes hear them referred to as silvicides (tree killers) or phytocides (plant killers).
