Best Post-Emergent Herbicide Granules for Lawn Weed Control
For existing lawn weeds in a granular format, The Andersons Professional Surge Weed and Feed is the closest match in this product list: it combines post-emergent weed control with lawn fertilizer. The other options include a targeted nutsedge concentrate, a crabgrass concentrate, and two pre-emergent granules that prevent new weeds rather than kill established ones. Check the product label for application directions, turf types, and restrictions before choosing.

The Andersons Professional Surge Weed and Feed
Best for: Lawn owners who want post-emergent weed control and fertilizer in one granular product. Surge is the strongest match here for shoppers specifically seeking post-emergent herbicide granules.
Its listed features describe a four-way weed-and-feed formula, 16-0-9 fertilizer, and control of more than 250 common weeds, including dandelions, clover, chickweed, and plantain. The product is also described for use during cooler spring and fall conditions.
Limitation: This is a combined fertilizer and herbicide, not a standalone weed killer. Confirm the label’s weed, lawn-type, and application instructions before use, and avoid it if you only want to prevent future weeds.
Atticus Empero Nutsedge Killer
Best for: Buyers targeting nutsedge, rather than looking for a general-purpose granular weed-and-feed. This product is a concentrate, so it is not a granular herbicide.
The listed active ingredient is 75% halosulfuron-methyl. The product is described as working down to nutsedge roots and tubers and as suitable for most established warm- and cool-season turf, including bluegrass, fescue, Bermudagrass, and zoysia.
Limitation: It is a specialized nutsedge treatment, not the closest choice for broadleaf weeds or crabgrass. Follow the product label for measuring and application directions; the listing notes a measuring scoop is included.
BASF Drive XLR8 Crabgrass Killer
Best for: Lawn owners seeking post-emergent control of crabgrass and other listed weeds in a liquid concentrate. Its active ingredient is quinclorac.
The product listing identifies crabgrass, foxtail, kikuyu grass, signal grass, and torpedo grass, along with broadleaf weeds such as clover, dandelion, and bindweed. It describes a water-based formulation, rainfastness in less than an hour, and up to 30 days of residual control.
Limitation: This is a concentrate, not granules. Its listed weed-control range does not mean it is appropriate for every lawn or weed; verify label directions and turf restrictions before applying.
Andersons Barricade Granules, 18 Pounds
Best for: Buyers who want granular prevention of new weeds, not treatment of weeds already growing. The package is listed to cover up to 5,800 square feet.
Barricade contains 0.48% prodiamine and is described for preventing grassy and broadleaf weeds, including crabgrass, poa annua, goosegrass, and henbit. Its dispersible granule technology is intended to dissolve with watering and move the active ingredient into the soil.
Limitation: The listing explicitly says this product will not eliminate existing weeds. Choose a post-emergent product instead if weeds have already emerged.
Andersons Barricade Granules, 40 Pounds
Best for: Buyers who need the same preventive approach as the smaller Barricade package but have a larger area to treat. The listed coverage is up to 12,880 square feet.
It shares the 0.48% prodiamine formulation, weed-prevention purpose, and dispersible granule technology described for the 18-pound option. It is intended for early spring and fall applications according to the listing.
Limitation: This is also pre-emergent, so it is not a solution for killing established weeds. The larger package is only a better fit when its stated coverage suits the area and the label’s directions.
Buying Guide: How to Choose Post-Emergent Granules
Do you need to kill weeds that are already growing?
Choose a post-emergent product when weeds have emerged. In this group, Surge is the granular option described for post-emergent weed control. Barricade is pre-emergent: it is designed to prevent weeds and will not eliminate existing ones.
Which weeds are you treating?
Match the product to the weed named on its label. Surge lists broadleaf weeds such as dandelions and clover. Empero is aimed at nutsedge, while Drive XLR8 lists crabgrass and several other grassy and broadleaf weeds. Do not assume that a product controls a weed just because it is an herbicide.
Does the product need to be granular?
Granules may suit shoppers who prefer a spreadable lawn product, while concentrates require label-directed preparation and application. Surge and Barricade are granules; Empero and Drive XLR8 are concentrates. If granular format is essential, the concentrates are not direct substitutes.
What should you check before applying?
Read the full label for the permitted turf species, application rate, timing, watering instructions, and any restrictions. Measure the treatment area and compare it with stated coverage. For combination weed-and-feed products, consider whether the lawn also needs fertilizer.
Frequently Asked Questions
Are post-emergent herbicide granules effective on existing weeds?

Which listed product is a granular post-emergent option?
The Andersons Professional Surge Weed and Feed is the listed granular product described for post-emergent weed control. It also contains fertilizer.
Can Barricade kill crabgrass that is already growing?
No. Its product information says it prevents weeds and will not aid in eliminating existing weeds. Select a labeled post-emergent treatment for emerged crabgrass.

No. Both are listed as concentrates. Empero targets nutsedge, while Drive XLR8 lists crabgrass and other weeds.
Should I choose the 18-pound or 40-pound Barricade package?
