Southern Ag Surflan AS, manufactured by Southern Agricultural Products, is a pre-emergent herbicide that eliminates various types of annual grasses and broadleaf weeds for up to 4 months.

Formulated with oryzalin 40.4% to inhibit the cell division of weeds such as crabgrass or common groundsel leading to stunt of growth and cease of activity.

Southern Ag Surflan AS is an effective low-use and economic liquid herbicide that can be used on different types of ornamental turf and warm-seasoned grass such as bahiagrass, Bermudagrass, buffalograss, centipedegrass, St. Augustine grass, zoysiagrass, and tall fescue.

Tools Needed

To use Southern Ag Surflan AS, you will need to mix and apply the herbicide in a backpack sprayer, handheld pump sprayer, or ground application equipment.

Do not use aerial application equipment or irrigation system.

How to Use

• Step 1: Determine how much Southern Ag Surflan AS to use by calculating the square footage of the treatment site. If unsure, then measure the length and width of the treatment area in feet and follow the formula (length X width = square footage). To find acerage, take the square footage and divide it by one acre (square footage / 43,560 = acre). For warm-seasoned turf, apply 1 to 1.5 oz. of Southern Ag Surflan AS per gallon of water per 1,000 sq. ft. Ornamental turfs will use the rate of 1.5 to 3 oz. of product per gallon of water per 1,000 sq. ft. Acreage applications for warm-seasoned turf and ornamental turf will use 2 quarts of product per 3 gallons of water per acre. Do not reseed for 90 to 120 days following application.
• Step 2: Shake well before mixing. Pour half the amount of water into the spray tank, add the measured amount of Southern Ag Surflan AS, then fill the rest of the way with remaining half of water. Maintain continuous agitation until solution is well mixed or if separation occurs.
• Step 3: Apply the Southern Ag Surflan AS solution mixture directly to the top of plants on a low pressure spray, but avoid overlaps. Water immediately after treatment or at least 21 days after first application. A second application may be required when 8 to 10 weeks have passed after first application. Do not make second applications on container grown ornamentals until 90 days have passed from the first application.

When to Use
