CRABGRASS & SANDBUR PREVENTER
Don’t let crabgrass make an appearance on your pristine landscape
Protecting your property from crabgrass and sandburs is easy. Crabgrass & Sandbur Preventer, containing Surflan®, is a selective pre-emergence surface-applied herbicide for control of annual grasses and many broadleaf weeds including crabgrass and sandburs.
WHERE TO USE:
- Landscape ornamentals
- Ground covers/perennials
- Nonbearing fruit and nut trees
- Nonbearing vineyards
- Christmas tree plantations
- Non-cropland and industrial sites
- Established warm-season turf (Bahia, Bermuda, buffalos, centipede, St. Augustine, Zoysia)
- Tall fescue
WHEN TO USE:
Use crabgrass & sandbur preventer before problem plants emerge. Crabgrass & Sandbur Preventer will not harm existing vegetation or weeds.
Crabgrass & Sandbur Preventer requires activation by rainfall or irrigation. Crabgrass & Sandbur Preventer will remain stable on the soil surface up to 21 days following application. In the absence of timely rainfall, irrigation can be used to activate Crabgrass & Sandbur Preventer. A minimum of one-half inch of rain or its equivalent in sprinkler irrigation is necessary to activate Crabgrass & Sandbur Preventer.
If weeds begin to emerge due to lack of rainfall or irrigation, shallow cultivate 1-2 inches deep to destroy existing weeds, or remove them by hand. Shallow cultivation to a depth of 1-2 inches will enhance herbicidal effectiveness. Erratic weed control may result if Crabgrass & Sandbur Preventer is not activated by rainfall, irrigation or cultivation within 21 days of application, or if existing weeds have not been removed.
HOW TO USE:
See the COMPLETE LABEL for specific use rates, mixing instructions and detailed instructions.
Ground Application: Apply Crabgrass & Sandbur Preventer as a directed spray to the soil surface or over the top of plants. Use only a properly calibrated, low-pressure herbicide sprayer that will apply the spray uniformly. Use screens no finer than 50 mesh in nozzles and inline strainers. Apply the appropriate rate of Crabgrass & Sandbur Preventer as outlined in “Crop Specific Use Directions” section of this label. In all cases, use sufficient water volume to obtain uniform coverage and deliver the desired rate of Crabgrass & Sandbur Preventer to the treated area. The volume of water used is not critical as long as the desired rate of Crabgrass & Sandbur Preventer is delivered uniformly across the area treated. When calibrating, determine the volume of water delivered by the sprayer to a given area (1,000 sq. ft., 1 acre, etc.). Then mix the desired rate of Crabgrass & Sandbur Preventer in the amount of water required to cover the entire area to be treated. As the amount of water used (spray volume) decreases, the importance of accurate calibration and uniform application increases. Check the sprayer daily to ensure proper calibration and uniform application. Maintain continuous agitation from mixing throughout application. Avoid spray pattern skips and overlaps that may result in incomplete coverage or overapplication.
Handheld or Backpack Sprayer Application: The amount of water used to apply Crabgrass & Sandbur Preventer herbicide is not critical but should be sufficient for uniform coverage of the target area. Calibrate by determining the volume of water required to treat 1,000 square feet. Use this calibration volume to determine the amount of water and Crabgrass & Sandbur Preventer herbicide needed to treat the target area. Note: Sprayer calibration (volume of spray needed to treat 1,000 square feet) will vary with each individual operator. See COMPLETE LABEL for calibration and mixing directions.
Aerial Application: Do not aerially apply this product.
Chemigation: Do not apply this product through any type of irrigation system.
Avoid spray drift to non-target areas when applying Crabgrass & Sandbur Preventer. Spray drift may result in reduced emergence of non-target plants adjacent to the treated area. Poor weed control may result if directions are not followed. Overapplication may result in crop injury or excessive soil residue.
Crabgrass & Sandbur Preventer does not control established weeds or weeds growing from stolons, rhizomes or root pieces. Therefore, areas to be treated should be free of emerged weeds. Crabgrass & Sandbur Preventer is orange in color and may cause temporary discoloration of sprayed surfaces. If this discoloration is undesirable, it may be altered by using a commercially available colorant such as Blazon or it can be removed by spraying the surface with water or washing with an industrial cleaner immediately after application. Crabgrass & Sandbur Preventer may also be applied with mulch colorants, such as Mulch Magic® or Nu-Mulch.
For orchard crops, including citrus, pome fruits, stone fruits and tree nuts, apply product only as a strip treatment in the tree rows; do not apply to row middles or drive rows.
Do not graze or feed forage from treated areas to livestock.
MODE OF ACTION:
Crabgrass & Sandbur Preventer controls weeds growing from seed. Crabgrass & Sandbur Preventer will not control emerged weeds. Crabgrass & Sandbur Preventer does not control established weeds, weeds growing from stolons, rhizomes or root pieces. Therefore, areas to be treated should be free of emerged weeds. Weed residues, prunings and trash should be thoroughly mixed into the soil or removed prior to treatment. In field applications, the soil should be in good tilth and free of clods at the time of application.
