Answer: The term pesticide is kind of a catch-all word for a collection of products designed to kill certain garden pests. The term includes insecticides (designed to kill insects), herbicides (to kill vegetation, mostly weeds), fungicides (to kill fungal diseases), miticides (to kill mites), rodenticides (to kill rodents), etc. It's important to know that not all products will kill all pests and not all are safe to use on all types of plants. If you're going to use an insecticide, for example, you'll need to first identify the insect and then look for a product that lists that insect plus the plant you intend to use it on. If the plant and the insect are not both listed on the label, the product can be harmful to the plant and ineffective against the pest. The same holds true for fungicides and herbicides. Hope this clarifies things for you.
