Syngenta Barricade 4FL Herbicide - Pre-Emergent Weed Control - Long Lasting Broadleaf Weed Prevention for Lawns, Turf Grass, Ornamentals and More

Description:

About this item:

  • PREVENT WEED DEVELOPMENT: Barricade 4FL herbicide controls the growth and development of weeds before they germinate. Barricade 4FL will not control weeds after they have germinated. In winter/spring, be sure to apply before soil temperatures reach 55 F for a 3-day average. In the fall, apply after soil temperatures fall below 50 F but before the ground freezes.
  • LONG-LASTING PRE-EMERGENT WEED PREVENTION: One application can prevent weeds all season when used as directed. You can apply this selective weed spray solution several months before germination and expect it to prevent crabgrass, chickweed, oxalis, goosegrass, Poa annua and spurge, well into the peak of the season.
  • BROAD-SPECTRUM HERBICIDE: This long-lasting pre-emergent herbicide is super effective on residential turf as well as production ornamentals and landscape ornamental trees and shrubs. It can prevent 30+ species of turf weeds, including both summer and winter annuals. It's all you need to stop pesky weeds from emerging in your lawn and landscape beds. See label for additional details. Length of control also varies by turf species and application time of year.
  • ULTRA EFFECTIVE & FLEXIBLE: You can use higher labeled rates of Barricade for season-long targeted weed control and use lower rates during shorter growing seasons. Its low solubility means it stays in the weed germination zone and will not break down even after heavy rain or snow. If you miss your timing for crabgrass germination, Barricade can be combined with Tenacity herbicide to control and prevent weeds.
  • Are you tired of dealing with weeding your landscape? Get great preemergent control with a lawn spray like Barricade 4FL. One application is all it takes for Barricade to control pre-germinated weeds for flower beds, lawn, turf, and more with Prodiamine as it's active ingredient. Established turfgrasses, Christmas tree farms, and Perennial and wildflower pairings will benefit from being treated with this selective weed concentrate solution. This product must be used only following its labeling and with the Worker Protection Standard, 40 CFR part 170. Refer to supplemental labeling under "Agricultural Use Requirements" in the directions for use section. No more ugly weeds will be in your landscape with the total vegetation control offered by Barricade 4FL's grass weed prevention for lawns.

    (function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } Great Pre-Em that does what it's supposed to. I apply at a quarterly rate (for me its .25 oz/K) and this bottle is good for a 3 month application. I can tell in areas I haven't applied the prodiamine, and can attest to it lasting 3 months where i DO apply it. Haven't had a weed all season, and I'm hoping that I can get it down in time to catch the Poa A and Poa T this fall.

    Put it out early and often. It puts the whammy on weeds before they can germinate. My lawn looks great. I'll be using this product regularly.

    Works great on controlling broad leaf weeds in your landscape. The “tip n pour” bottle makes it easy to measure out the right amount. It has a no stain formula so you don’t have the yellow color staining hard surfaces like driveways. Since it’s concentrated you only need a small amount.

    This pre-emergent liquid was applied on patio pavers in the Spring. Nothing came up in the cracks all summer. One suggestion, Please put a proportion formula on the package. It was a guessing game to decide how much water to liquid to mix. I ended up with 4 water to 1 part liquid.

    5.0 out of 5 stars Works amazingly well on pot anum weeds.

    This works well against pop alum weeds. If sprayed in early spring, weed seed do not germinate.

    I’ll update with effectiveness; just wanted to let folks know it’s tricky to time if you have pets(I use Preen, trifluralin, where the pets need to go)

    Didn’t see immediate change, but it works.

    I applied this product according to the manufacturers advise and overall I didn’t see any changes in the weeds in my yard. I’m going to see what other products are available and I can’t recommend this product.
