Rimsulfuron 25DF is a herbicide that controls poa, ryegrass and other related weeds in bermudagrass and other species of warm season turf. With the flexibility of killing existing weeds in the turf and being able to keep weeds from growing in the first place, this weed killer gives unparalleled protection to the target turf. Just apply the product and wet the affected area, to get the herbicide into the soil, with the product becoming rainfast four hours after application. Established weeds will die in one to three weeks and any new weeds will die a few days after germination. This post-emergent herbicide also helps the turf transition from its dormant, cold season state into its full warm season growth. It also protects against bluegrass during the fall, if overseeding is necessary.

INFORMATION
Quali-Pro Rimsulfuron 25 DF may be used in weed management programs along roadsides, highway medians, at industrial plant sites, and utility substations for control of a number of grass and broadleaf weeds. Where food and/or feed crops are grown or in areas where food and/or feed crops are planned to be grown, care should be taken to prevent any direct spray of Quali-Pro Rimsulfuron 25 DF onto or to drift to these crops or planned planting areas since severe crop injury may occur.
APPLICATION INFORMATION
Apply Quali-Pro Rimsulfuron 25 DF at 4 ounces per acre in a broadcast application making sure that coverage is uniform. Use a minimum of 10 gallons of spray solution per acre. Nozzle selection should meet manufacturer’s spray volume and pressure recommendations for preemergence or postemergence herbicide applications.
Pre-emergence:
Quali-Pro Rimsulfuron 25 DF must be activated by rainfall and applied when soil temperatures are cool for best preemergence and residual activity. Make applications to take advantage of normal rainfall patterns (minimum of 1/2 inch) and cooler temperatures. For best results, moisture for activation should occur within 2 to 3 weeks after application. To provide a broader spectrum of residual weed control, Quali-Pro Rimsulfuron 25 DF may be applied in a tank mixture with other registered preemergence herbicides. When weeds are present at application, include a labeled burndown herbicide such as glyphosate, paraquat, or glufosinate with an appropriate adjuvant. When applied according to the use directions, Quali-Pro Rimsulfuron 25 DF will provide residual (preemergent) control of the following weeds:
Post-emergence:
For best results, make postemergence applications of Quali-Pro Rimsulfuron 25 DF to young, actively growing weeds and include a spray adjuvant. Refer to the label of the tank mixture partner(s) for any additional use instructions or restrictions. Follow the most restrictive labeling of any of the tank mix component products.

I am in central Texas.
Rimsulfuron 25DF is not labeled to be used on St Augustine grass specifically, only warm-season turf such as Bermudagrass, zoysia, and centipede. We would not recommend using this product on St Augustine grass. You could test a small area first for tolerance, but we cannot guarantee that it would not damage the turf. Keep in mind that this product is not for use on residential turfgrass. If you would like to tell us what weeds you are targeting, then we can recommend an alternate product for you.

Sine Rimsulfuron 25DF isnt for residential use, what would be a good alternative for post emergent control of poa annua on bermuda grass
Certainty Herbicide is a great option for a warm season turf like Bermuda to remove poa annua and other broadleaf weeds. We would recommend putting down a split application of a pre emergent like Pendulum 2G this fall to help prevent the poa annua from coming up next spring. To learn about split applications and why they are beneficial you can see our How To Video Here.
We recommend contacting the manufacturer of Rimsulfuron 25DF Quali-Pro directly with specific product questions by calling 800-242-5562, or via their website's contact page here.
