We do carry Blindside Herbicide that is a selective post-emergent to eradicate henbit in Zoysia, Bermunda and St. Augustine grasses. You can also apply Dimension 2EW Herbicide prior to the weeds germinating for a pre-emergent control. Please refer to the product label for complete mixing and application instructions for each product.
If it rained that soon after application, Blindside Herbicide WDG would probably need to be reapplied but you should wait at least 21 days to do so.
Yes, Blindside Herbicide WDG can be applied to a Bermuda lawn to control spurge. You should apply this product in the morning or later in the evening when temperatures are cooler; usually below 85 degrees is safest for your turfgrass. You should avoid spraying in a manner that would allow direct spray or overspray onto the roots or other parts of desirable trees.
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)
Per the Blindside Herbicide WDG label: Application to Zoysiagrass in spring transition may result in discoloration. If turf discoloration occurs after an application of Blindside Herbicide turfgrass will generally recover with new growth. Discolored leaf tissue will be removed with mowing.
It is recommended to apply Blindside at temperatures less than 85 degrees.
Blindside Herbicide WDG is labeled for use on St. Augustine grass, and the label does not exclude any specific cultivars. If there is discoloration after applying Blindside, established turf will generally recover well. As with all herbicides, you should not apply to turf that is under stress from extreme heat, drought, disease, or other similar situations. It is recommended to apply Blindside at temperatures less than 85 degrees.
Yes, Blindside Herbicide WDG can be applied to established tall fescue safely if used as directed on the product label.
Yes, Blindside Herbicide would be safe to apply in a lawn with centipede grass.
We would not recommend tank mixing Blindside Herbicide WDG with Tenacity as Tenacity requires a surfactant to use and Blindside does not. Plus they are labeled for much of the same weeds so you would only need one or the other. Per the label: USE OF SURFACTANTS: Temporary discoloration of some turf types may result from use of surfactants or adjuvants with Blindside Herbicide. High temperatures and high relative humidity may increase the risk of temporary discoloration.
Per the product 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 shoudl not be applied.
If you preform a compatibility test and have no issues then you can mix a liquid fertilizer with it.
Per the label instructions, you can use .15 - .23 oz / per 1000 sq feet of Blindside Herbicide WDG for warm season turf. So for example, at the highest rate of .23 / 1000 sq ft, and you are using 2 gallons of water to cover 1000 sq ft, in your 20 gallon sprayer you would use 2.3 oz and it would cover 10,000 sq ft.
For your 4 gallon sprayer, you will need to calibrate by determining the volume of water required to treat 1,000 sq ft. Use this calibration volume to determine the amount of water and Blindside Herbicide WDG needed to treat the target area. (If using 2 gallons to cover 1,000 sq ft, then at the highest rate of .23 / per 1,000 sq ft, you would use .46 oz of Blindside Herbicide WDG in your 4 gallon sprayer).
It is recommended to apply Blindside Herbicide WDG when temperatures are less than 80 degress. Discoloration may occur if applied in high temperatures and high relative humidity per the product label.
You should not use Blindside Herbicide in a manner that would cause it to contact desirable plants in flower beds either by direct spray or by drift. You would have to very carefully spot treat the nutsedge only and avoid any contact with the flowers
Dismiss Herbicide is a great option for nutsedge and dandelion and is safe for use in St. Augustine grass. The mixing ratio is 0.18-0.275 fl. oz. per gallon of water and will treat 1000 square feet.
Two applications of Blindside Herbicide 21 days apart may increase control of weeds over a single application; however, do not exceed 10 oz. product per acre per year. Please review the product label for more information.
Blindside is labeled for dollarweed control and should do a good job. The rate for warm season grasses is 0.15 - 0.23 per 1,000 sq. ft. (6.5 - 10 oz. per acre).
