Surflan Herbicide
Sulflan Herbicide, manufactured by DOW/CORTEVA, is a pre-emergent liquid concentrate to be mixed for surface application and can deliver up to 8 months of weed control. This pre-emergent effectively controls grasses and weeds and it is orange in color which helps it to act as a spray marker during application.
Tools Needed
To use this product you will need a backpack, tank, or hand sprayer. A hand-pump sprayer would be ideal for smaller applications
How to Use
- Step 1: Fill a hand-pump sprayer 3/4th of the way with water and then mix at a rate of 1.5 - 3 oz per 1000 sq ft. 2 1/2 gallons. Fill the sprayer the rest of the way with water and agitate the sprayer until mixed.
- Step 2: Spray the product onto your lawn or other areas where you would like to control problematic weeds. Make sure to put the sprayer on a fan setting to get nice uniform coverage.
- Step 3: Reapply as needed to control weeds before they emerge.
Where to Use
Surflan Herbicide can be used on residential and commercial lawns, industrial sites and on garden or ornamental plants.
When to Use
Timing is crucial when using Surflan. Since the product is a pre-emergent, it needs to be applied before the problem weed emerges, especially if it's been a reoccurring problem. If the weed is already growing, Surflan Herbicide will not work (unless on select weed types) and you will have to use a post-emergent herbicide.
Safety Information
Make sure to wear the proper PPE when applying this product (goggles,gloves, face mask etc). The product is safe for pets and children if used according to label directions. After treatment, keep pets and children away from the treated area until the product as dried.
Special Considerations
Depending on the time of application, the locations of application, desired control (post-emergent or pre-emergent treatment) different rates apply when using this product. Check the label for detailed instructions on how to apply according to the state where you reside, the timing of the application (spring, summer, fall) and your desired control (post-emergent or pre-emergent control).
