Quali-Pro Negate 37WG is a wettable granular, so it is a solid concentrate that you dilute in water and apply as a spray. It is applied at 1.5 fl oz per acre and spray volumes of 20 to 80 gal/acre and pressures of 25 to 35 psi.
You can use Negate 37WG on your bermuda lawn to control poa annua (annual bluegrass). You can apply to either dormant grass or when the grass is fully green, but you do not want to apply a post-emergent like this while the grass is in transition, such as during Spring green-up.
Per the new supplemental label, for poa annua, you would use 1.5 oz per Acre. If you are treating an area smaller than 1 Acre, then the manufacturer recommends diluting the entire 1.5 oz bottle in a gallon of water first (not in your sprayer but in a separate container) since there are different sized prills in the concentrate. You would then use 3 oz of your mixed solution in at least 1 gallon of water per 1000 square feet. The remaining initial solution can be stored for 2-4 weeks, just be sure you agitate the solution before mixing and re-applying. You can reapply on your dormant turf after 4 weeks if the target weeds are still present.
Be sure that you use a dedicated sprayer to apply this product or that you clean thoroughly the entire spray equipment before using other products in it. Please refer to the label for complete instructions and make sure this product is labeled for use with your specific grass type.
Unfortunately, we are not able to confirm with the manufacturer if this mixture rate would still be effective for weed control therefore we would recommend to mix a new mixture of Negate 37WG Herbicide at the proper ratios for best results.
Yes, when used as directed on the product label for Negate 37WG, you just do not want to apply to turf that is less than 1 year old. This includes sodded or seeded turfs.
With Negate 37WG, it is necessary to mix the entire contents of the bottle into one gallon of water to create the correct suspended concentrate of the two active ingredients. You will then take 3 ounces from that gallon of mixed solution and mix that into one gallon of water for spot treatments. The original gallon you mixed the entire bottle into will be good for about a month.
Negate 37WG Herbicide is not labeled for velvet grass (yorkshire fog) and unfortunately we could not find a herbicide labeled to kill it. Since this perennial grass has a shallow root system, the most common method is to hand dig the velvet grass without harming your lawn. Another method is to spot treat the weeds directly with Roundup QuickPro and reseed any bare spots after 2 weeks.
We recommend waiting a few days after application before mowing. You can use Negate 37WG to either dormant grass or when the grass is fully green, but you do not want to apply a post-emergent like this while the grass is in transition, such as during Spring green-up.
Negate 37WG Herbicide is best applied anytime when weeds are young and actively growing and air temperatures are between 60 to 85 degrees. A non ionic surfactant is recommended for best results however can cause temporary discoloration to turf if under stress from drought, heat, disease, etc.
We recommend applying in early morning or late afternoon/evening when temperatures are coolest for the day and the application has time to dry before to day time temperatures reach above 85 degrees.
Please review the product label for application rates and more information.
