Negate 37WG would be a great product to use to control annual ryegrass in Bermuda. The product label states that when treating for annual ryegrass a repeat application may be required in 4 to 6 weeks. Please refer to the product label for specific application instructions.
Negate 37WG is labeled to be used on dormant and non dormant turf and states on the product label: “Some chlorosis of the turf may occur following application”. It’s not recommended to use on turf in the transition state from green to dormant, or dormant to green up.
Unfortunately only time will tell if the lawn will recover from the over application of Negate 37WG. The only way to reduce the effects of an herbicide would be use an activated charcoal product pretty immediately after spraying (within hours).
No, Negate 37WG is only labeled for application to warm season bermudagrass and zoyiagrass when used on residential lawns.
Any mixed solution of Negate 37WG Herbicide with water in a sprayer should be used within 24 hours. The shelf life of the contents in the original container is good for 3-5 years. Please be advised, agitation is required constantly when applying with selected sprayer equipment.
Negate 37WG has a three year shelf life if stored in a cool, dry place away from extreme temperatures.
Quali-Pro Negate 37WG should not be applied to residential lawns and not as a spot application. 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 should not mow within 2 days of an application of an herbicide such as Negate 37WG.
Negate 37WG Herbicide does not require watering in after application. You should wait 24 hours to do so if watering is needed.
No, Negate 37WG cannot be applied in or around desirable plants, bushes, trees, shrubs or ornamentals. Per the product label, applications should be avoided where desirable root zones may extend or in locations where the chemical may be washed or moved into contact with their roots. In areas where Negate 37WG has been applied, do not plant shrubs and trees in treated areas for at least 1 year after the last application or bedding plants for at least 2 years.
To treat buttonweed and other broadleaf weeds, hand pulling the weeds or directly spot treating with a non selective herbicide like Roundup Quick Pro is recommended.
For grassy weeds, Fusilade II is one of the top choices to kill actively growing grassy weeds in landscape beds, flowers, shrubs, bushes, and trees and will not injure listed tolerant plants/ornamentals.
You would use 1.5 fl oz per acre using spray volumes of 20 to 80 gal/acre and pressures of 25 to 35 psi. For spot treating, or for treating smaller areas, the manufacturer recommends diluting the entire 1.5 oz bottle of Negate 37WG 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.
Negate 37WG is best applied in temperatures above 55 degrees and when target weeds are actively growing and healthy. We suggest contacting your extension office for advice on specific timing in your area.
Negate 37WG will control perennial ryegrass in a bermuda lawn as long as you are following the instructions on the product label. For the best time on when to apply in your specific region, we would recommend contacting your local cooperative extension office. Post emergent products are applied when the weeds are actively growing.
Negate 37WG is not labeled for Fescue but does great for poa annua in Bermuda. Because poa annua and Fescue are so closely related, there are few products that will kill the poa annua without also harming the Fescue. The only one we are currently aware of is called Prograss and it is very expensive. Your other options would be to either spot-treat with a Roundup-type product and then reseed with the Fescue in those areas, or you can use a pre-emergent like Prodiamine 65 WDG in the fall to prevent the poa from growing in the first place.
You should not mow 3 days before or 3 days after the application of Negate 37WG.
Negate would be a great to option to use for poa trivialis and is safe on bermuda.
Negate 37WG will need to be applied with a non-ionic surfactant. Also, Negate 37WG needs to be mixed first into a gallon of water if you're not going to treat an acre with the 1.5 oz bottle. As the user, you will need to review the product labels to be sure the one you want to mix with Negate 37WG can be tank mixed with other herbicides. It is recommended to do a small jar test mix first to make sure both products are compatible and follow the most restrictive label.
Negate 37WG cannot be used on Fescue or Saint Augustine grass.
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.
