User questions & answers

Question:	Will it kill Johnson grass and Dallas grass
Answer:	It will not kill Dallis grass
Question:	We have a 2600 sqft lawn and a 4 gallon backpack commercial sprayer. How much drive, water and surfactant should we add to the sprayer
Answer:	I bought 1/2 gallon of XLR8 for probably 10,000 sf of lawn. I used 2 ounces per gallon + 1 teaspoon or so of surfactant on actively growing crabgrass in a bermuda and fescue central Arkansas lawn this summer. I spot treated the crabgrass, which had taken over probably 25% of the lawn and small patches of it in throughout. I've hit newly sprouted crabgrass or areas that I missed or that survived several times a couple weeks apart, and almost all of the crabgrass is dead. I still have more than 1/2 left. I don't think you would need to spray more than 1/4 of your tank at a time for 2600 sf, I would think 1/2 gallon would last you several years.
Question:	What is the shelf life of this product
Answer:	3 years
Question:	What is the mixing ratio for the 1/2 gallon and how big area it will cover, and how many times do have to apply. Thank you
Answer:	Correction to my previous answer to your question: I mix 3oz Drive in 2+ gallons water and apply to 2000+ square feet, not 1000 as stated. This approximates the recommended (maximum) application rate for Bermudagrass of 1.45oz/1000 sqft. Another suggestion is to use 1oz per generous gallon of water per 1000sqft so you could use 3 applications (3oz per year per 1000sqft) and not exceed the manufacturer's limit of 2.9oz per 1000 sqft per year.

User questions & answers

Question:	will it damage shrubs and flowers
Answer:	Keep the spray away from any type of ornamental flowers or Shrubs. It is made for lawn weed control only, not flower beds. You may try using preen granules around your flower beds. If you use colored mulch around those flowers and shrubs you will help control the weed population and enhance the beauty of the shrubs and flowers. Hope this helps. Steve
Question:	how may square feet does the entire 40 ounces of the product treat
Answer:	According to the manufacturers (Bayer's) directions 3.2 fl. oz. mixed in one gallon of water treats 500 sq. ft. - So your 40 fl. oz. divided by 3.2 equals 12.5, then times 500 gives you 6,250 sq.ft.Anthony
Question:	does it contains quinclorac
Answer:	yes Quinclorac 1.61%
Question:	it does not say what the mix is, how much per gallon of water
Answer:	3.2 oz per gallon treats 500 sq ft.

User questions & answers

Question:	Will it kill poa Anna in bermuda
Answer:	This is definitely a late answer. Quinchlorac is the better crabgrass, post-emergence killer. Though Quinclorac can boost broadleaf activity when tank-mixed with other broadleaf-specific herbicides, especially phenoxies like 2,4-D and MCPP. Quinclorac can provide excellent control of some other broadleaves, like white clover and dandelion, on its own. Quinclorac can miss excellent post-emergence crabgrass control when crabgrass is at the two-to-three tiller stage. Also, Add a methylated seed oil(surficant) to quinclorac to improve efficacy.
Question:	Will this kill highway grass in centepede

Provides post-emergent control of tough-to-control weeds Controls weeds at seeding reducing weed competition KEY BENEFITS Prevents and controls crabgrass pre or post up to four tillers Eliminates weeds at seeding so new grass can flourish.

• Tenacity is a systemic pre-emergence and post-emergence herbicide for the selective contact and residual control of weeds in turfgrasses.

User questions & answers

Question:	How much lawn will this 8oz bottle cover? We have .3 of an acre
Answer:	The 8 oz bottle will produce 96 gallons of solution using 1/2 teaspoon per gallon of water. I forget what the coverage is but it will certainly cover .3 acres using a pump sprayer.I have been using mine on my .5 acre for two years and I have only used about 1/3 of the 8 oz.
Question:	Anyone know how tenacity compares to a product called "dismiss"? i have some nutsedge to get rid of and i'm trying to decide which to get. thanks
Answer:	tenacity is labeled for nutsedge. . Dismiss is the the better choice, however. Usually with tenacity, you have to apply it at least two to three times, at two week intervals. They are both broad spectrum. Tenaciity's claim to fame is its ability to kill grassy weeds, like Nimblewill. They are both labeled for Goose grass. I don't think Dismiss is labeled for Nimblewill. PS: spectricide makes a good 4 way for the home owner. It has 24d, dicamba, quinchlorac, and sulfantrazone (dismiss). spelling. they sell it on amazon and lowes.
Question:	can i apply over
Answer:	The official answer is no for most herbicides. Depending on what you're trying to control. Here is a link to one of the best reports I have found - http://archive.lib.msu.edu/tic/golfd/article/2012oct33.pdf. This report shows great results with mid-80 degree temperatures in the control of POA ANA (Which is what I'm challenged with controlling). The general rule of thumb with Tenacity is the higher the temperatures the more applications (small dosage) needed for control. Tenacity has a half-life of 5-15 days depending on the temperatures - the higher temperatures the lower the half-life. The report and other reading also indicates that Tenacity needs to stay in the plant at or above the half life levels for ~ about 14 days or so to gain a high level of control. My advice would be to look for a week when temperatures are expected to average below 90 degrees and make a couple applications during that week and observe the control that you achieve - then goo from there. I experimented for a couple seasons using this report to get a feel for the best application frequency, rates, temperatures and timing (time of year). I hope this is helpful. Good luck and all the best.
Question:	what is surfactant? Is it included with tenacity
Answer:	A surfactant is a separate product that you add to your applicator tank. It helps the Tenacity stick to leaf blades and better kill the weeds. I used Bonide Turbo spreader sticker. It, or something similar is available in small bottles in garden centers. The ratio I used for nimblewil was 1 teaspoon of Tenacity and four teaspoons of surfactant per 1 gallon of Water.

Answer:	Yes ! It will be safe on St. Augustine lawns. Overall the product is mild on the grass stress and dries quickly.
Question:	Will Trimec kill bahia grass
