There are several basic types of herbicides, each targeting
certain plant pests (weeds, grasses.) Pre-emergent herbicides
are used to stop the germination of plant seeds. Post emergent
herbicides can be selective or non-selective. Products such as
Roundup can be considered total vegetation, non selective and
post emergent. A non-selective herbicide tries to kill most
plants while a selective herbicide is designed to kill specific
types of plants, usually grasses or broad leaf weeds. Total
vegetation products (listed on this page) are considered soil
sterilizers, killing all plant nutrients in the soil and
preventing any vegetation from surviving. When spraying
herbicides on plants, a surfactant can be used to increase the
efficiency of herbicides. Examples of different herbicide types
are listed below. - Surflan A.S: 1.5 ounces per 1,000 square
feet to prohibit weed seed germination in turf and ornamental
beds. Best used as spring application for crabgrass control. -
