Barricade 65 WDG Herbicide

Barricade 65 WDG (WDG means Wettable Dispersable Granule) is a pre-emergence herbicide that offers low rate, season-long control of 30 grassy and broadleaf weeds, including crabgrass, goosegrass and Bluegrass (Poa annua), in turf and ornamentals. Its unique, non-staining active ingredient and application flexibility have quickly made Barricade one of the most popular herbicides in the green industry.  Barricade WG can be applied in the fall to control crabgrass through the following growing season. Barricade is available in 3 lb. and 10 lb. containers.

As a low cost alternative to Barricade 65 WDG, we recommend Resolute 65 WG, a wettable granule with the same active ingredient Prodiamine (65%), but for much less. Resolute is manufactured by Syngenta the same manufacturer of Barricade.

Please read the product label for complete use instructions.

Barricade WDG is a pre-emergent herbicide that controls susceptible weeds by preventing growth and development of newly germinated weeds. Weed control is most effective when Barricade is activated by at least 0.5 inch of rainfall or irrigation, or shallow incorporation (1-2 inches) before weed seeds germinate and within 14 days following application.

Barricade may be applied as a single application or in sequential applications to control weeds germinating throughout the year. All applications must be made before target weeds germinate because Barricade will not control weeds that have already emerged.

The amount of Barricade to apply depends upon the length of residual weed control desired (the higher the application rate, the longer the control) and the turf species.

Long Residual Control

The unique formulation of BARRICADE 65WDG offers weed protection that lasts. Even at the lowest rate, BARRICADE offers an average of three months crabgrass control. At the highest rate (1.5 pounds per acre), control extends to 8 months.

This means fewer applications for you. One application in the spring controls crabgrass even in Southern locations. In the cooler climates of the northern U.S., one fall application provides season-long crabgrass control.

BARRICADE is the longest-lasting pre-emergent weed control product on the market. One application takes you through the end of the season, giving you and your workers more time for everything else on your busy schedule.

Barricade 65 WG is labeled for use on the following turf grasses:

Bermudagrass, Bahiagrass, Centipedegrass, Kikuyugrass, Seashore Paspalum, St. Augustinegrass, Tall Fescue (including turf-type), Fine Fescue, Zoysiagrass, Buffalograss, Kentucky Bluegrass, Perennial Ryegrass, Creeping Bentgrass (0.5 inches or more in height).

QHow much Barricade 65 WDG should I mix per gallon of water?


The first thing you need to know when using an herbicide such as Barricade 65 WDG is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 0.185-0.55 oz per 1,000 sq ft . To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 0.185-.055 oz of product with for each 1,000 sq ft area that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either by rainfall or by sprinkler) following the application.

QI have 1.5 acres, how much Barricade will I need? How soon do you need it to rain after applying?
I will be using a 15 gallon sprayer to apply

AYou must read the product label to determine how much you need as the rate per acre depends on what you are treating, what type of grass that you have, and what area of the country you are in.  Typically you apply between 1 and 1.5 lbs of product per acre.  The product needs rain to activate and to get deep into the root system where upcoming weeds are trying to germinate.  You should either water the product in or apply when it will rain in a few days.  The product must have water within 14 days of application, otherwise you will not get very good results.

QHow many gallons of water do I need to use to spray per 1000 sq ft when I am using Barricade ?

AYou should mix the required amount of Barricade (0.185-0.55 oz per 1,000 sq ft) in to at least .5 gal of water. In this case, the water only acts like a carrier so the actual amount of water you use to apply the product does not matter very much and you could use .5 to 2 or 3 gallons and you will have pretty much the same result. After Barricade has been applied, it must be watered in with at least 1/2 inch of water (rain or irrigation is fine).

QAugust in Pennsylvania. Is it too late to apply this product?
I planted a new lawn in an area disturbed by construction equipment this spring. It came in nicely but is now being overrun by grassy weeds. It is August in southern Pennsylvania. Is it too late to apply this product or do you recommend something else?

ABarricade 65 WDG Herbicide is a pre-emergent. Once it is too warm, it is usually to late to apply it. However, you can use a post-emergent. Pre-emergents such as Barricade 65 WDG can be used in the late fall to prevent futher growth of weeds for the upcoming spring. Please let us know if you have any additional questions.

QWhat is a good pre-emergent for weed control in hybrid bermuda grass? I have nut grass and splurge in it
Also poua grass

AWe are not sure what part of the country you are in, but most of the country is past the time to apply pre-emergents.  You should apply two applications of Barricade around Feb. 15th and then again around May 15th to prevent these grasses from coming up.  As for treating existing weeds in your grass, you should use Sedgehammer for the nut grass and End Run for the splurge and other broad leaf weeds you may have.  The poua grass will typically burn out here on its own very shortly since it is an annual grass.

QCan I spray Barricade 65 WDG with a Permagreen ride-on sprayer?
I have a 25 acre HOA to treat. I'm trying to figure out the easiest way to do a large area with fields and houses and is Barricade the best route?


Yes, you can use Barricade 65 WDG Herbicide with just about any type of spray equipment as long as you are able to mix†the solution†properly. You need to be able to agitate the tank during initial mixing and during the application to maintain a well-mixed spray suspension, per the product label. If your sprayer does have adequate agitation, then you may want to consider a liquid pre-emergent herbicide instead. Barricade does cover a wide variety of both grassy and broadleaf weeds and is safe to use around most established turf and ornamentals.

QWill Barricade 65 WDG Herbicide kill Russian sage?
Can I add to brush killer?


Barricade 65 WDG Herbicide is not labeled for Russian Sage however, the active ingredient in this product of prodiamine is mentioned in several articles as a great ingredient to use on the Russian Sage. I have attached one of these articles as well. Overwatering can induce bad health and root rot of Russian Sage also. It does poorly in wet soil with poor drainage, and eventually dies from winter-kill. Once the plant dies, you can remove the stump that remains from your garden.†

QWill Barricade 65 WDG Herbicide harm worms and counteract Microlife?
I'd like to keep my lawn as chemical-free as possible but realize there are limitations when trying to eliminate weeds. What effect does Barricade have on worms and micro organisms?


Barricade Herbicide is just an herbicide so it should not harm the worms or any other micro-organisms in your lawn. We would recommend speaking directly with the manufacturer for any specific questions on beneficial creatures in your lawn. Their phone number is (336) 632-6000.

QCan this be used with a gilmore dial sprayer model 362 and if so what setting shall i use

AWe do not recommend applying herbicides using hose end sprayers. The problem with using the hose end sprayer for the Barricade 65 WDG Herbicide application is that they are not very accurate and you can wind up dispensing more/less product than needed in a given area which can lead to less than desirable results.

QIs Barricade chemically compatible with glyphosate sodium and diquat-dibromide?
I wish to mix barricade, glyphosate and diquat-dibromide for long-term vegetation kill/control (I want bareground sparing the trees). I am aware that the recommendation is to alternate treatments, however, I've been unable to find compatibility information in neither the label nor MSDS. The label essentially says "try it and if it separates, it's incompatible" is there anything more specific, like a chemical compatibility guide? Thank you in advance.


Before mixing Barricade 4FL with other pesticides in the spray tank, test for compatibility by mixing all components (carrier and pesticide products) in an appropriate container in proportionate quantities. For example, 1 qt. would be 1/100 the volume of a 25 gals./A spray rate. At 1.0 lb./A, the Barricade 4FL rate would be proportional to 6 ml. per quart. Add approximately 1 teaspoon to a quart of water.

If components do not ball-up or form flakes, sludge, gels, oily films, or layers, then the mixture is compatible. Let the mixture stand for 15 minutes. Incompatibility will usually occur within 5 minutes after mixing. If components are not compatible, use a compatibility
agent and rerun the test to determine if the mixture is suitable. If the components are still not compatible, do not tank mix.
According to the manufacturer label, Barricade 4FL can be used with glyphosate products. We would recommend doing the tank test for diquat-dibromide.

QSpray Application - What time of year
I was told that I could spray Barricade 65 WDG in the fall from the folks I purchased it from. But as I read the label it sounds like I would get the best bang for my buck would be around the Fed - March time frame. What do you recommend?

ADifferent weeds will germinate at different times of the year. To control winter weeds it is recommended to treat prior to germination in the fall and then to treat again in the spring for the summer weeds. It all depends on the target weeds and your region. We would recommend you contact your local Cooperative Extension Office for more specific recommended application timing in your area for your weeds.

QYour Barricade label says to be used to kill weeds in established turfgrasses,
What about application to Bermuda grass that is still dormant after the winter? Rosemary

ABarricade is a pre-emergence herbicide that controls susceptible weeds by preventing growth and development of newly germinated weeds.  It does not kill actively growing weeds.  It can be safely applied to dormant or non dormant Bermudagrass.  Application timing will vary by region and the best person to ask about application timing is your local master gardener who works at your local cooperative extension office

QWhat if my dog eats the grass after being treated with Barricade?
My dogs always eat the long grasses at the fenceline. A few days after Barricade treatment, my dog started to to show signs of hind leg muscle weakness. I have ruled out other possible causes.

AThe Barricade 65 WDG Herbicide is safe for pets once it is dry. If you suspect that the Barricade 65 WDG Herbicide has had an effect on your dog then we would recommend that you contact your Veterinarian's office and provide them with the Barricade 65 WDG Herbicide MSDS so that they can make a proper diagnosis and provide the appropriate treatment..

QHow to remove Barricade 65 WDG or render it ineffective
Well, the grass people came by today and applied barricade as part of their "spring" treatment. Unfortunately, they spray all lawn areas, including the bare spots that need reseeded. How much water should I use on the bare spots to dilute the barricade so that I can reseed over the next few weeks. Reseeding cannot wait the 6-8 weeks recommended.

ASince Barricade 65 WDG Herbicide is a pre emergent, applying more water will actually help further push the active ingredient into the root system. We can only recommend reseeding 8 weeks after application, if not longer. Please contact the manufacturer Syngenta at 866-796-4368 for help trouble shooting.
