04/20/26
Trifluralin 4EC Herbicide, manufactured by Drexel, is a long-lasting preemergent herbicide controlling many annual broadleaf and grassy weeds in over 20 different use sites.
This product suppresses weeds by inhibiting root growth and can be applied as a broadcast application, lay by application, as well as soil incorporation, or added to a dry bulk fertilizer.
Trifluralin 4EC Herbicide offers continued weed control for the new grower and the seasoned grower.
Tools Needed
To use Trifluralin 4EC Herbicide, you will need to mix the product in a sprayer of your choosing such as a backpack sprayer, handheld pump sprayer, a professional spray rig for larger volume applications or you may also use professional incorporation equipment such as a field cultivator.
How to Use
- Step 1: Determine how much Trifluralin 4EC Herbicide to use by measuring the square footage of the treatment area. To do this, you will need to measure the length and width of the treatment area in feet and then multiply them together ( length X width = square footage). For acreage, take your square footage and divide it by one acre ( square footage / 43,560 = acre). For vegetable gardens, you will need 2.25 to 4.5 tsp of Trifluralin 4EC Herbicide per 1 to 5 gallons of water per 1,000 sq. ft. For under-paved surfaces in small areas, a rate of 9 to 12 ounces of this product in 3 to 4 gallons of water per 1,000 sq. ft. Refer to the product label for more specific rates and restrictions.
- Step 2: Fill your selected sprayer tank with half of the required amount of water and add the measured amount of Trifluralin 4EC Herbicide. Fill the sprayer the rest of the way with the remaining half of the water. Close the sprayer and shake it till the product is well mixed.
- Step 3: Spray the soil with the Trifluralin 4EC Herbicide mixture, making sure to get even coverage via the fan spray setting.
