Quali Pro T/I 2.5 G Trifluralin Herbicide

Quali Pro T/I 2.5G Trifluralin Herbicide, manufactured by Quali-Pro, is an effective granular pre-emergent herbicide used for the control of more than 100 different types of broadleaf weeds, and annual grasses in managed ornamentals, Christmas tree plantations, and other terrains.

This granule herbicide works by preventing weed seeds from germinating with the active ingredients trifluralin 2.0% and Isoxaben 0.5% before they emerge during the growing season. Its mode of action uses a cellulose biosynthesis inhibitor to control a broad spectrum of weeds and contains a seedling growth inhibitor (dinitroaniline) to prevent their regrowth.

Quali Pro T/I 2.5G Trifluralin Herbicide is a long-lasting pre-emergent herbicide that can be used on more than 635 labeled ornamentals for up to 8 months, saving you time and money. Its low water solubility means it will remain in the weed zone once it has been watered in with rainfall or irrigation.

Tools Needed

You will need a rotary or drop spreader designed to apply granular herbicides or pesticides. You could use a hand spreader for smaller application areas, but we recommend a push broadcast spreader for larger application areas.

How to Use

• Step 1: Determine how much Quali Pro T/I 2.5 G Trifluralin Herbicide to use by measuring the square footage of your treatment area. To do this, measure the length and width of the treatment area in feet, then multiply (length X width = square footage). Quali Pro T/I 2.5 G Trifluralin Herbicide should be used at a rate of 2.30 to 4.60 pounds per 1,000 square feet.
• Step 2: Calibrate your spreader to the right setting for application and load the proper measured amount of granules into it. No two spreaders are alike; therefore, follow the manufacturer's instructions for proper calibration. If you have previously used your spreader, be sure to clean it thoroughly to avoid a product mixture.
• Step 3: Broadcast the granules uniformly using your spreader type. You may need to do two perpendicular walkthroughs to get excellent coverage.
• Step 4: After you have completed the application, water the lawn to activate the granules. For effective results, the granules must be watered into the upper 1 to 2 inches of soil within 3 days of application.

Where to Use

Quali Pro T/I 2.5 G Trifluralin Herbicide can be used on established Christmas tree plantations, non-bearing fruit and nut trees, non-bearing vineyards, non-cropland, and ornamentals (container and field grown, groundcovers/perennials, and landscape).

When to Use

Timing is important when using this product as it will not control weeds that are already up out of the ground and showing. Spread it in early spring, late summer or early fall before weed seeds have germinated. Apply on calm days when wind speeds are low to minimize granule drift. Be sure that, at the time of application, the soil surface is free of clods and is smooth.

Safety Information

Quali Pro T/I 2.5 G Trifluralin Herbicide is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when handling or applying this product.

Pets and children should be kept away from the treated area until completely dry.

Special Considerations

One 50lb bag of Quali Pro T/I 2.5 G Herbicide covers 10,000 square feet, depending on your selected rate. Injury may occur if T/I 2.5G is applied to plant species not listed on this label.
