Blindside Herbicide WDG
  • Alternate Image 1
  • Alternate Image 2

Blindside Herbicide WDG is a selective post-emergent that controls over 70 broad-leaf weeds and sedges selectively working its way up through the roots as well as attacking through foliar contact. Blindside Herbicide WDG is even effective against hard to kill weeds like doveweed, buttonweed, and dollarweed. In one week you will see visible proof of control, much more quickly than other products. You can apply a second follow-up application of Blindside Herbicide WDG if necessary.

One of the key benefits of Blindside Herbicide WDG is its one-of-a-kind mode of action that will works in the soil to keep weeds from germinating the next year. This mode of action will drastically reduce weeds the following season in treated areas.

Use Blindside Herbicide WDG in the majority of warm season grasses and some cool season as well. Blindside Herbicide WDG, when used according to the label, can be used in warmer temps than other products.

Not for use on seashore paspalum or Bahiagrass.

    2 of 5 stars  Floratam stopped growing
    By Steve in Margate Florida on 01/09/2013
    Verified Purchase

    I applied Blindside December 22nd and it's now Jan 9th! Close to 3 weeks now. I have Floratam variety of St. Augustine grass. The label says its ok to use on St. Augustine but doesn't specify which varieties. Several varieties of weeds are dying but the dollar weed of which I'm the most concerned doesn't want to die. The grass has stopped growing but looks like its going to come back. I'm happy that the majority of weeds are going away but disappointed that the dollar weed won't die. I wish I would've bought Celsius or another herbicide. I emailed FMC and asked them if it was approved for Floratam. I got a generic answer that was a copy and pasted from the label saying on new varieties of grass it should be tested before used on the entire lawn! Floratam has been around since 1977 and was kind of upset at the generic answer! I hope this review helps other Floridians with warm season grass

    5 of 5 stars  Best broadleaf control I have ever used on St. Augustine
    By James in Hilliard, Fl on 04/04/2015
    Verified Purchase

    I do my own lawn maintenance and have fought broadleaf weeds every year in my St. Augustine. I have tried everything you can buy at your local do-it-yourself centers. Nothing has ever come close to what Blindside accomplished in one application. You have to use a backpack type sprayer, no hose end sprayers, and it will devastate all broadleaf weeds, period. I put it out in March so temps were moderate in NE Florida and had zero damage or yellowing of the St. Augustine. Be sure and use the surfacant with it. The only regret I had was not using a color additive to see where I had sprayed. I had to go back a week later to hit a few spots missed. Buy it, you will not regret it and follow directions closely.

    4 of 5 stars  An Updated Review
    By Steve in Margate, FL on 03/27/2014
    Verified Purchase

    My first review was 2 stars and I am now giving it 4. I have continued to use Blindside for more than a year now, and although it slows the growth, and yellows my Floratam Saint Augustine it does a good job of controlling a wide variety of weeds (including dollar weed) and the saint Augustine does make a comeback. March is the best time to use it because the temps are low 80s. I have used it with temps in the 90s and it still worked well, it just took a little longer for the grass to make a comeback. And the neighbors are very jealous because my yard is the best in the neighborhood. (My Opinion)

    1 of 5 stars  Didn't phase my dollar weeds
    By Jeff in Jacksonville, fl on 04/26/2015
    Verified Purchase

    Dollar weeds are on label but this stuff didn't seem to phase them one bit.

    Expert Response   Expert response:
    You may need to try two applications of the Blindside for Dollarweed since it can be a tough weed to control for an entire season. (Just be sure that you don't exceed the annual rates on the product label: Dollarweed also needs lots of water to thrive - probably less than your lawn, so adjusting your watering schedule may help to slow down the Dollarweed as well. We apologize that you are not happy from the results from the product. We are always happy to assist you by telephone, email, or live chat as well.

    3 of 5 stars  blindside herbicide WDG
    By Sally in longwood florida on 04/02/2015
    Verified Purchase

    I wanted to purchase celsius WG but you no longer sell it so it was suggested to order this blindside. I put it down and have found it to be good on sedge grass but my oxalis in places are still growing and have purple flowers. In Florida it has been very hot so it seems like the grass is yellowing in places. On celsius I could spray in hot weather and it didn't do anything.

    5 of 5 stars  Worked Great!
    By Doug in Jacksonville, FL on 06/17/2017

    My step-mom bought a home with a terrible looking yard. It has large patches of St. Augustine grass but covered in weeds - mostly globe sedge and one part had tons of dollar weed. I applied Blindside and both of these weeds are nose-diving within 10 days. Very happy with the results of one application. I'll follow up with another application a little later as I used the lowest application rate and can do two per year. Also, we had a heavy thunderstorm about 20 hrs after application which probably reduced the effectiveness, but I'm still very happy with the results. At a cost of just over $2 per 1000 square feet, you can't beat it for residential lawns and it's enough to last for years.

    5 of 5 stars  Product works!
    By Eddie in Porter, Texas on 08/29/2017

    I have over an acre of beautiful Rivera Bermuda in Porter, TX. which is becoming infested with Dove grass/weed. This stuff is hard to kill and it spreads very quickly in the summer months. I have tried many broad leaf killers to fight the stuff and even though some work, it takes several applications to be successful. I purchased an 8 oz. bottle of Blindside (and it is quite expensive) and I was a little concerned with the small size of the bottle and how much it would cover. The directions said to mix .15 to .23 oz. for 4 gallons of water to spot apply with a back sprayer. They provide a measure to get the .15 or .23 oz. amount. Since I have had such an issue with the Dove Weed, I opted for the .23 amount and let me tell you IT WORKS!! And the 8 oz. bottle will go a long way. I cannot believe how concentrated this stuff is. For Dove Weed, I highly recommend Blindside.

    1 of 5 stars  Not so good
    By Ronald in tyler, tx on 02/25/2017

    Used on St Augustine in east tex. Applied per lable. Did NOT kill my dollar weed or clover, but sure wiped out my St. Aug.

    Expert Response   Expert response:
    Thank you for your comments! There are many factors when using herbicides that can affect the outcomes. St. Augustine is a particularly sensitive turfgrass, especially if you are applying herbicides when the turf may be under stress from heat or drought. Blindside can sometimes cause tip burn on St. Augustine at labeled rates, especially if you have Floratam, but the turf should recover from this. If you used a surfactant with Blindside, that would cause extra sensitivity, too. Blindside does typically do very well on dollarweed, although it is not unusual to need multiple applications for this plant (or for mature clover). We are happy to troubleshoot with you by email or by telephone at 866-581-7378. We appreciate your feedback and your business!

  • 5 of 5 stars  Great broad leaf control
    By Jane in Durham, North Carolina on 09/22/2017

    Blindside has been effective in killing the dove weed in my Bermuda grass lawn. Effect of the spray was visible in a bit over a week; nearly a month later, the weed is continuing to die. The included measuring cup was very helpful as just a little of this herbicide goes a long way. I believe it will also kill the nutsedge and green kylinga; eliminating the need for such weed-specific herbicides

    By Bill in Saint Johns, Florida on 11/04/2017

    This stuff kicks ass! It is killing weeds more completely than anything I have used. I was planning to repeat at around three weeks, but it is possible it won't be necessary.

QWhat is the best month to apply this product in St Augustine , FL and Zoysia grass?


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.

QHow much Blindside to use in a 2 gallon sprayer?
What is the per gallon mixing ratio?


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)

QWhat is the best pre-emergent product or products to control crabgrass, sedge grass and broadleaf weeds.
I am looking for a liquid or granular product that can be applied to my St Augustine / Zoysia lawn in St Augustine Fl. If possible is their one product that will control all of these problem weeds or will I need to apply more than one product. Also, what time of year should this be applied

ABlindside Herbicide would be a great pre-emergent for established St. Augustine and Zoysia lawns. It is labeled for sedges, crabgrass and many other listed weeds. Please refer to the product label for specific application instructions.

QHow do I control a Doveweed problem in Bermuda grass?
My lawn is Bermuda grass and the lawn size is about 3500 Sq Feet. What is your recommendation for a cost effective (preferably generic) recommendation that will address the DoveWeed problem? if you can please advise on a: 1)Pre emergent? 2)Post emergent?


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.

QIs Blindside Herbicide safe for a Horse Pasture?
Live in Central Florida and need a food weed killer/control for my horse pasture. How long do I have to wait to graze my horses? Safe for Bahia grass?


Blindside Herbicide WDG is not labeled for horse pastures.  We would recommend GrazonNext HL Herbicide, as it is safe to use on pastures with bahiagrass. There are no grazing restrictions using GrazonNext HL Herbicide. We would suggest they not be in the area during the application and while the surfaces are wet, once the treated surfaces are completely dry then they can return.

Blindside is not labeled for whitehead broom and we apologize but we are unable to find a product that can be safely used for it on a Floratam St. Augustine lawn that would not also kill the grass.  We would recommend checking with a master gardener at your local cooperative extension office to see if they are aware of any products that have been successfully used by others in your area.

QHow much chem do i need?
I live in Dallas Tx. I deal with St.Augustine and Bermuda. No cool season grass. My sprayer sprays 2 gal of water over 1000sq ft. Pressure is somewhere around 30 psi. It holds 20 gal of water. How much Blindside do I need? Also if I wanted to spot spray and my sprayer holds 4 gal, how much do I use in 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).

QHow do I mix Blindside Herbicide WDG for use on St. Augustine?
I have 3500 sq ft St. Augustine and a serious crab grass problem, ilive in Corpus Christi, Tx. humidity is usually pretty high. i have a 2 gal. spray bottle.. and need to knw correct mixture for my situation. temp this time of the year around mid to high 70s


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.

QAfter using Blindside how soon may I sow bahia grass seed?


Blindside WDG does not list Bahiagrass as one of the tolerable turf types. Blindside Herbicide has demonstrated tolerance on both cool and warm season turfgrasses. However, not all varieties have been evaluated. Turfgrass managers desiring to treat newly released varieties should first apply Blindside Herbicide to a small area prior to treatment of larger areas. We recommend contacting the manufacturer FMC directly at 1-800-321-1362 for clarification or your local cooperative extension office here.

QCan Blindside Herbicide WDG be used with Quicksilver Herbicide on St. Augustine grass?
If so are there any advantages?


Per the Blindside Herbicide WDG product label it can be mixed with most other herbicides in a tank mix. 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. 

Unless there are weeds/grasses on one label that are not on the other there aren't any advantages to combining Blindside with Quicksilver Herbicide
