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.

Pre-emergent Herbicides

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.
Atrazine 4L: 3 tablespoons per gallon, for use as a pre-emergent treatment but used mostly for its post emergence ability on winter broadleaf weeds.

Post Emergent Herbicides

Trimec Lawn Weed Killer: 5 ounces per gallon of water treats 1,200 square feet. For control of broadleaf weeds in warm season turfgrass.
Manor Herbicide: Must read label for mix rate. For control of Bahiagrass in warm season turfgrass.
Corsair Herbicide: Must read label for mix rate. For control of fescue in warm season turfgrass.
SedgeHammer Herbicide (use instead of Manage Herbicide): .9 grams per 2 gallons of water. Controls nutsedge in turfgrass.
Momentum: 1 ounce per 1,000 square feet. For use in Bermuda and Zoysia turf to control a wide variety of broadleaf weeds. Great on Buttonweed and spurge.
Vantage Herbicide: 3/4 ounce per 1,000 square feet. Controls annual and perennial grasses in Centipede turf. Over the top of ornamentals and ground cover.
Image Herbicide: 2.5 ounces per gallon. Controls broadleaf, sedges and grassy weeds in turf and ornamentals.
Fusilade Herbicide: 3/4 ounce per gallon. Controls grassy weeds. For use in Zoysia turf, ornamentals and some ground cover.

Non-selective Herbicide

Roundup Pro Dry: Each 1.5 ounce pack mixes to 1 gallon of water. Systemic, non-selective herbicide that translocates through the plant to kill at the roots.
Reward Herbicide: 3/4 ounce per gallon of water. Control similar to Roundup but not quite as good systemically. Great to add with Roundup for burn down. Also carries an aquatic label for use in and around water for control of plant material. Roundup Pro Dry is no longer in production and has been replaced with the improved Roundup product QuikPro Dry herbicide.
QuikPro Dry, with Roundup: Each 1.5 ounce pack contains Glyphosate and Diquat, a quick kill combination. Both ingredients are non-selective but only Glyphosate is systemic. Neither of the active ingredients have a long persistent residual in the soil, allowing for planting soon after application.
Scythe Herbicide: 4 ounces per 1,000 square feet. Used for fast burn down of plant material. Great if used with Roundup for best control.
Brush Killer BK-32: 16 ounces per five gallons of water. For control of woody plants and perennial weeds in non-crop areas.
When roots clog sewer or septic lines, a specialty non selective herbicide is needed. There are two products available for this type of problem: granular and foam formulation. K-77 is a granular root killer; Root Killer Foam is a material that expands into a foam, once it comes into contact with water. Both of these products are safe to use in septic systems.

Vegetation Control

Pramitol: Read label for mixing instructions Use only in areas where complete control of vegetation is required. This product can leach through the soil to other areas.
Sahara DG: Read label for mix rates. Total vegetation control. Designed not to leach as badly as Pramitol or other products. Great for fence rows.

Surfactant

Spreader Sticker: 1/2 ounce per gallon. Used to increase liquid pesticide/ herbicide efficiency. This product will make your application more rain fast and give you better coverage of your application. Best results with herbicide treatments. Can also be used as a wetting agent.
