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).
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.
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.
It is recommended to apply Blindside at temperatures less than 85 degrees.
The date on the bottle of Blindside Herbicide is the date the product was manufactured. The shelf life of most products is 3-5 years once opened. It is possible that products could lose their effectiveness depending on how it has been stored.
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.
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 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.
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.
Blindside Herbicide WDG is safe for use around established trees and bushes, but you should not contact them directly. Be sure to apply on a less windy day.
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).
We recommend performing a tank mix jar test when mixing products first. We do not see any benefit to mixing 2, 4D with Blindside Herbicide WDG as it treats grassy and broadleaf weeds.
You should not use Blindside Herbicide in a manner that would cause it to contact desirable plants like azaleas and hydrangeas either by direct spray or by drift. If you do need to spot treat broadleaf weeds around ornamental flowers or shrubs, it would be better to use a product like glyphosate which does not persist in the soil or have any volatility.
Blindside Herbicide WDG should be used or discarded within 24 hours of mixing.
Blindside Herbicide WDG can be applied as a broadcast or as a spot treatment. Please refer to Table 1. on the product label for the mix rate according to they type of turf you have (cool or warm season) It is recommended to use 0.5 to 4.0 gallons of water per 1,000 sq ft.
Blindside is not labeled to control bahia grass, so we cannot say for sure that it would work. Generally, because bahia and St. Augustine grasses are closely related, it is difficult to find a product which would kill one without harming the other. It is usually recommended to spot treat the bahia with a glyphosate product such as RoundUp QuikPro and then maintain the health of the St. Augustine so that it will fill in the bare spots.
Blindside Herbicide WDG works best if applied to actively growing listed weeds when the temperatures are less than 80 degrees.
