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)
When using Blindside Herbicide WDG it could take up to 10-14 days for complete results to take place, although you will often see yellowing within a few days. It is recommended to apply the product at temperatures less than 80 degress. Discoloration could be imminent in high temperatures and high relative humidity per product label. Per the label two applications of Blindside Herbcide 14 to 20 days apart may increase control over a single application, depending on the weeds you are treating.
We recommend that you wait a minimum of two to three days after the application of Blindside Herbicide to mow.
Blindside Herbicide works best when the weeds are actively growing for post-emergent control. We recommend that you apply when the temperatures are not very high and the humidity is low per the product label. Please contact your local Master Gardener for specific application times in your area.
Best weed control results with Blindside Herbicide WDG will be obtained when no rainfall or irrigation occurs within 24 hours after application and it does need to be watered in within 7 days of application.
Blindside Herbicide WDG should be applied when the dogs are not present and remain out of the treated area until the surfaces are completely dried.
Yes, you could apply the Blindside 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.
The product we recommend for post-emergent control of doveweed is Blindside Herbicide. It is labeled for various other weeds as well. The mixing ratio is 0.15 to 0.23 oz. per gallon of water. This will generally treat 1000 square feet.
For pre-emergent control of doveweed, we would recommend using FreeHand 1.75G Herbicide. It is labeled for use on bermudagrass and controls various grasses and broadleaf weeds. The mixing ratio is 2.3 lbs. per 1000 square feet.
There are not very many products that are specifically labeled for this particular weed. We would recommend using the pre-emergent product now when the soil temperature is above 55 degrees. The post emergent can be used if you were unable to control the doveweed in the Spring.
When using Blindside Herbicide WDG on warm season turfgrass such as St. Augustine, you will use 0.15 - 0.23 oz. per 1,000 sq ft, or 6.5 - 10 lbs per Acre, per the product label. Keep in mind that post-emergent herbicides like Blindside will be most effective when the target weeds are young and actively growing.
We also recommend using a pre-emergent herbicide in the future to help prevent new crabgrass. A great choice for your yard would be Hi-Yield Weed and Grass Stopper with Dimension Herbicide.
You should not mow 2 days before or 2 days after applying Blindside Herbicide WDG.
Per the Blindside Herbicide WDG product label: Best weed control results will be obtained when no rainfall or irrigation occurs within 24 hours after application. If no rainfall or irrigation occurs within 7 days after application of Blindside Herbicide in the amount of 0.5 inches, then irrigation of at least 0.5 inches is recommended. You do not need to water before hand.
Blindside Herbicide WDG is labeled to eradicate doveweed in Bermuda turfs.

Blindside Herbicide WDG is best applied when target weeds are actively growing and healthy, usually best between temperatures above 55 and below 85.
Blindside Herbicide WDG needs about 2-3 hours to dry and become rain fast before expected rainfall or watering.
There is not a specific amount of time you need to wait after applying Blindside Herbicide before using a fertilizer. We do recommend waiting at least one day since it is ideal to have at least 24 hours after using Blindside before rainfall or irrigation in the treatment area.
Blindside Herbicide WDG is labeled to control Doveweed and Yellow Nutsedge in St. Augustine and Centipede lawns. Apply 0.15 to 0.23 fl oz per 1,000 sq feet, two applications 14-21 days apart may increase control over one application.
We suggest to make the application either early morning or late afternoon/early evening when the turf is not stressed. Applying Blindside Herbicide WDG to stressed turf from heat, drought, mowing, overwatering, etc can result in turf injury.
You will want to keep applications of Blindside Herbicide WDG outside the dripline of any desirable trees, shrubs, ornamentals.
