Prevent Weeds All Season Long With Barricade®

Barricade® is The Andersons professional-grade pre-emergent weed control. Containing 0.48% of the active ingredient prodiamine, Barricade is one of the best granular weed preventers on the market. It can be used on established lawns and landscape beds to prevent over 30 grassy and broadleaf weeds like crabgrass, goosegrass, foxtail, lambsquarter, henbit and more.

Barricade features The Andersons patented Dispersible Granule (DG) Technology which allows each granule to disperse into thousands of micro particles after coming into contact with water. Because of DG Technology, Barricade can move past the thatch layer of your lawn and into the soil where it prevents the germination of weed seeds.

When To Apply Barricade - Spring and Fall

Application timing is critical to Barricade performance. To prevent summer annual weeds in both northern and southern turf types, apply Barricade in early spring prior to soil temperatures reaching 55°F at a four-inch depth. Applying at this time will prevent weed seeds from germinating.

In southern zones, Barricade can be reapplied in the fall to prevent annual winter weeds like poa annua, also known as bluegrass.

Remember, Barricade must receive irrigation or light rainfall of at least 0.2 inches for the herbicide prevention to activate.

Barricade and Seeding

In the same way that Barricade prevents the germination of weeds, it can also inhibit the germination of grass.

If you already seeded, wait 60 days or until after the second mowing, whichever is longer, before you apply Barricade. However, keep in mind that Barricade, and all other pre-emergents, have a specific soil temperature window in which it should be applied.

How long you should wait to seed or overseed after applying Barricade depends on your climate. Refer to the table below for recommended intervals.
