Barricade 4FL Herbicide is a pre-emergence herbicide offering low rate, season long control of over 30 broadleaf and grassy weeds that include goosegrass, Poa annua and crabgrass. It prevents weeds from continuing to grow and stops the development of new seeded weeds. Applications can be applied as early as January and just one application will allow it to last the whole season. This product will not stain landscape features such as fences.
NOTE: This product has been open and repackaged for extra security to avoid any spillage.
Barricade 4FL can be used alone with water or tank mixed with other herbicides.
Mixing alone: Must be mix thoroughly in spray tank to ensure uniform application. Fill spray tank 1/4 with clean water and start agitation. Add product and continue agitation throughout application. A spray colorant may be used to mark areas.
Tank Mixing: Test compatibility with other pesticide products before mixing. Follow chart on product label for specfic order and rates.
Look on product label for charts on types of weeds controlled and use rates on turfgrass and others.
I was really impressed by this product. For years I used Dimension 2EW and had to apply twice per year in heavy doses because of the soil type in my area (northern North Carolina Piedmont), sloped portions of yard, etc. For a while I was considering the WDG version of this, but was always hesitant as keeping the solution agitated enough concerned me. That said, this liquid is probably just as good if not better, especially using a backpack sprayer. I put down 1 oz per 1000 sq ft, which is a little higher than what the label suggests, but again, my soil conditions are unusual in that I have some sloped portions of my 1.25 acre yard and the soil in general is quite hard in areas, and somewhat sandy in others.
Over this past season where we went through the remnants of two hurricanes and rainfall was nearly 30 inches above normal (normal is 45 inches per year, we got nearly 75 this year), crabgrass popped up in only very small patches, and only in and along the swale lines--a bit of post emergent spraying throughout September easily took care of these. There was literally no crab on the level areas all season long.
All this said, please keep in mind one thing...this product does not do as well as Dimension 2EW on at least one other listed weed; it's performance on foxtail was less than I would have had with 2EW. But, to me, it's a small price to pay not having to spray twice per year, use less chemical at a lower cost, and have nearly eliminated my crabgrass problem--it is this area of the United States that invented crabgrass back in 1786 :)
How much of Barricade 4FL should I use in a 1 gallon sprayer?
The label does not give specific info about mixing small amounts.
Herbicides are much different than other chemicals because water just acts as the carrier. In this case the product label recommends you use .23 - 1.1 oz per 1,000 sq ft to be treated. Please read the product label to determine the exact usage rate for your needs as it varies according to the species of grass you have. Once you have determined the usage rate per 1,000 sq ft you can follow the outlined steps to decide how much water you should use per 1,000 sq ft (this will vary for every person as the type of equipment will be different and the walking speed of the applicator will be different).
1.Mark off an area that is 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 (no herbicide) noting the final level of water in the spray tank. 3. Spray the marked 1,000 sq ft area with a sufficient volume of water to provide uniform coverage.
4.Refill the spray tank with the amount of water it took you to cover the 1,000 sq ft area 5. Add the pre-determined amount of herbicide that is needed to cover the 1,000 sq ft area to the spray tank. Example: If the sprayer uses 1 gallon of water to cover 1,000 square feet and the desired application rate of the chosen herbicide is .80 fluid oz./1,000 square feet, then you would add .80 fluid ounces of the chosen herbicide to every 1 gallon of water to be used.
Can Barricade 4FL Herbicide be tank mixed with Trimec herbicide?
Is it safe to tank mix Barricade and Trimec herbicide and spray my lawn with it?
Barricade 4FL Herbicide can be mixed with other herbicides as long to provide a broader spectrum of weed control or to control emerged weeds. Make sure to follow instructions for rates and restrictions on each product label.
