Barricade DG Pre-emergent: Best Granular Pre-emergent

Barricade DG Pre-emergent: Best Granular Pre-emergent

Samuel Barrick

Only a few products are relied on like Barricade. It is the solution for landscapers, homeowners, municipalities, golf courses, and many other fields. While it comes in many different variations, like a liquid, water-soluble, granular, the Barricade DG .48 Prodiamine made by The Andersons is by far the best formulation of this product due to its ease of use and great results.

The prodiamine active ingredient in this product is carried by The Andersons' patented DG (Disposable Granular) formulation allows for it to quickly break down and start working fast. 

The Andersons’ Barricade DG .48 Prodiamine comes in an 18 lb or 50 lb bag with a small granular size making it easy to spread even in tight areas. 

What Makes it the Best? 

Barricade .48 Prodiamine gives landscapers, contractors, homeowners, and more a granular solution that can be applied on turfgrass, landscape beds, nursey crops, and Christmas tree farms. It does a great job preventing annual grassy weeds like Annual bluegrass, crabgrass, goosegrass, barnyardgrass, and many more. It also controls some broadleaf weeds like henbit, chickweed, oxalis, spurge, lambsquarters, and more. 



How Does it Work? 

Barricade is a pre-emergent, meaning that it will control seeds as they germinate. It restricts root growth, prohibiting the seed from developing after it germinates. Barricade does not work on anything that has already germinated and established roots. It will also not work anything tuberous. This makes applying it in landscape beds safe for any existing plants and will not prevent bulbs from springing up. 

How Long Does it Last? 

While it changes in certain conditions, Barricade lasts for 2 to 6 months depending on the application rates. When using it in turfgrass it can last around 3 to 4 months. In landscape beds up to 6 months with a higher ai application. To improve the residual control, applying as a split-application will provide longer control. Apply the second application rate around 4-6 weeks after the first application for best results. 

Application Instruction 

Apply 150 to 300 lbs per acre. Be sure to cover the whole area for best results and apply ½-inch of irrigation or rainfall within 14 days of application.
