Trimec Bentgrass Formula, manufactured by PBI Gordon, is a post-emergent herbicide meant to control broadleaf weeds that show up on bentgrass and other sensitive grasses.
It is especially effective in eliminating clover, chickweed, knotweed, sheep sorrel, oxalis, and spotted spurge. The product can be used in a wide range of temperatures down to 50F, which makes it so you can use it for weed control in early Spring and Fall.
Tools Needed
To use Trimec Bentgrass Formula, you will need to mix the product into a sprayer of your choosing such as a backpack, hose-end or hand-pump sprayer. For the average job, a hand-pump gallon sprayer works best.
How to Use
- Step 1: Determine how much Trimec Bentgrass Formula to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment areas length and width in feet, then multiply them together (length X width = square footage). Mix at a rate of 1.1 to 1.5 fl oz per 1,000 sq ft and agitate well in the sprayer to ensure it's well mixed.
- Step 2: Spray the target weed, making sure to get even coverage via fan spray setting. You can either spot treat or broadcast the product over an area depending on the weed issue and severity.
- Step 3: Reapply the product after 30 days if weeds are still persisting.
Where to Use
Trimec Bentgrass Formula can be used on turf, landscapes and golf courses. It is especially useful for treating bentgrass greens, tees, fairways, and aprons. It's also registered for use on buffalograss, centipedegrass, and St. Augustinegrass.
When to Use
Use Trimec Bentgrass Formula when you notice broadleaf weeds emerging on your bentgrass or other sensitive. The great thing about Trimec Bentgrass Formula is it can be used almost any time of the year as it is effective down to 50 degrees Fahrenheit so you can apply it in early Spring or in the Fall. Apply when weeds are young and actively growing. Avoid applying during high temperatures and when it is dry.
Safety Information
Trimec Bentgrass Formula 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 mixing and applying this product.
Keep people and pets out of the treatment area until the spray has dried.
Special Considerations
According to the label, use no more than 6 pts per acre, with a maximum of 2 broadcast applications per year, with at least 30 days between applications.
