Negate 37WG, manufactured by Quali-Pro, is a tough post-emergent herbicide that comes in wettable granule form.
The active ingredient in the herbicide is both Rimsulfuron and metsulfuron which makes it a dual powered herbicide that can successfully control over 35 different annual grasses and broadleaf weeds in established warm season turfgrass.
Just a single application can deliver between 8 to 12 weeks of control so you don't have to apply so often.
Tools Needed
To use Negate 37WG Herbicide you will need to mix the product into a power sprayer of your choosing such as a professional pesticide spray rig for large volume applications.
How to Use
- Step 1: Determine how much Negate 37WG you need by calculating the acreage of the application site. To do this, measure (in feet) and multiply that area length and width then divide by 43,560 (length x width = square footage /43,560 = acreage). Negate 37 is applied at 1.5 fl oz per acre and spray volumes of 20 to 80 gallons of water per acre. Check the label for specific rates as they vary depending on application site and the weed you are trying to control.
- Step 2: Fill your spray tank with the appropriate amount of water and then add the appropriate amount of Negate 37WG based on your calculations. Fill with the remaining half of water and then agitate the sprayer until the solution is well-mixed.
- Step 3: Spray the target weeds, making sure to get even coverage via fan spray setting.
- Step 4: Check back after 2 weeks and reapply if necessary to get complete control.
