You can apply Blindside to established dormant or fully green Bermuda grass.
Blindside Herbicide WDG should only be applied to established listed turf that has been mowed a few times. Fall pre-emergents applied help with the poa annua seen in the spring but should not be applied when your overseeding.
Blindside Herbicide WDG is labeled to suppress Crabgrass. Please be sure to review the product label for more information and complete application instructions before use.
Herbicides are a lot different than other concentrated products and can be hard to understand at first. The application rate depends on the the type of turf you have and how quickly you apply the product. You will need to read the product label to determine the correct usage rate for your needs (you did not give us any information about the type of lawn, region or application program you will be using so we cannot give you exact rates). The amount of water used to apply Blindside Herbicide is not critical, but should be sufficient for uniform coverage of the target area. Calibrate by determining the volume of water required to treat 1,000 square feet. Use this calibration volume to determine the amount of water and Blindside needed to treat the target area (see the following calibration example). Note: Sprayer calibration (volume of spray needed to treat 1,000 square feet) will vary with each individual operator. Steps in Calibration: 1. Mark an area of 1,000 square feet (i.e. 20 by 50 feet or 25 by 40 feet). 2. Place the sprayer on a level surface and add water noting the final level of water in the spray tank. 3. Spray the marked area with a sufficient volume of water to provide uniform coverage. Refill the sprayer to the same level as before measuring the amount of water added. The measured water added to the sprayer is the volume needed to cover 1,000 square feet.
The amount of Blindside per 1,000 sq ft:
Cool Season grasses: 0.075 - 0.15 per 1,000 sq. ft. (3.25 - 6.5 oz. per acre)
Warm Season grasses: 0.15 - 0.23 per 1,000 sq. ft. (6.5 - 10 oz. per acre)
Blindside Herbicide when used across St Augustine grass should be used between 0.15 and 0.23 oz per 1000 sq/ft. If you used it at 0.32 oz this would have been too high of a rate for that grass type to tolerate. What blend of St Augustine grass do you have in the lawn? Certain cultivars are more sensitive to herbicide applications such as Floratam and Bitterblue. The Blindside Product Label also states that if its used with a surfactant then discoloration should be expected as it increases the chances of damage to the lawn and is not really required with this product to work effectively.
Blindside Herbicide will generally turn target weeds yellow before they brown and die. Since fescue grass grows in clumps, you may need to reseed any areas that are bare after you kill undesirable plants in the lawn. Keep in mind that control of poa annua once it has seeded is very difficult.
According to the product label for Blindside Herbicide, Jasmine is not on the list of weeds controlled/suppressed by Blindside Herbicide. However, the product also should not be used around desirable ornamentals, shrubs, or trees. Prior to using Blindside Herbicide, I recommend carefully reading over the product label and to speak with your local cooperative extension.
Blindside Herbicide WDG is labeled for wild onion and wild garlic in Zoysiagrass at the mix rate of 0.15 - 0.23 oz per 1000 sq ft or 6.5 - 10 oz per acre.
A surfactant is NOT recommended as temporary discoloration of some turfgrass species may resullt. Please review the product label for complete application instructions.
As long as Blindside Herbicide WDG is mixed correctly and agitated occasionally it should not clog your sprayer.
Blindside Herbicide WDG is not labeled for sandspurs. Please take a look at Hi-Yield Atrazine Weed Killer as it is labeled for both sandspurs and centipedegrass.
Blindside Herbicide WDG would be the best option to apply to established Bermuda for doveweed and buttonweed. It is not labeled for basketgrass, unfortunately, and there really are not a lot of options for treating this weed. It should be spot treated with RoundUp, and then reseed/resod in those areas, but see if the Blindside helps control it first to avoid another application.
Blindside Herbicide WDG is not safe to use on ryegrass and some other cool-season turf; it is primarily for use on warm-season grasses. A similar product for use on cool-season turf is Solitare WSL or Solitare WDG. Solitare contains Sulfentrazone to target broadleaf weeds and sedges, plus Quinclorac to target grassy weeds like crabgrass. If you only need the broadleaf weed and sedge control, then you can use Dismiss Herbicide, which contains only the sulfentrazone.
Tenacity is a uniqe herbicide in that it has both pre-emergent and post-emergent properties, so it may be especially useful if you need a product to apply at the same time as seeding. Tenacity will target yellow nutsedge but not purple nutsedge or kyllinga.
Blindside Herbicide WDG is the best product to treat for Barnyard grass safely in Fescue Lawns. Apply at 0.15 oz per 1000 sq feet.
If you applied Blindside Herbicide WDG when the soil was moist but not saturated or with puddles it should still be effective. When applied at high temperatures it might also harm the grass and only time will tell if it affected it or not. When you have high temperatures you should try to apply late in the evening or early in the morning to prevent damage.
Dichondra is not on the list of weeds controlled/suppressed by Blindside Herbicide. This plant is used so often as a desirable groundcover and it is not usually listed as a target weed on herbicide labels. However, the product should not be used around desirable ornamentals, shrubs, or trees.
Blindside Herbicide WDG can be used to control crabgrass (along with many other weeds) in St. Augustine grass.
It is recommended that you wait about 1 week between applying Blindside Herbicide WDG and a Weed n Feed to avoid over stressing your turf.
Blindside Herbicide is not labeled as safe to use on bahiagrass, so we do not recommend you use this on your mixed centipede and bahia lawn. On centipede only, you would use up to 3.25-5 oz to treat ½ acre in at least 10 gallons of water. We recommend using at least 1 gallon of water per 1,000 sq ft for most applications.
Per the Blindside Herbicide WDG label: Blindside Herbicide has been found to be compatible with most herbicides, fungicides, insecticides and growth regulators commonly used in turf and ornamental plant management. However, when preparing a new tank mix conduct an appropriate compatibility test by mixing proportional amounts of all spray ingredients in a test vessel (jar) prior to tank mixing with other products. Shake mixture vigorously and allow it to stand for five to ten minutes. Rapid precipitations of the ingredients and failure to re-suspend when shaken indicates that the mixture is incompatible and should not be applied.
