Successful turf management starts with proactive weed prevention. Pre-emergent herbicides create a protective soil barrier that stops germinating annual weeds; including crabgrass, goosegrass, and common broadleaf species before they compete with healthy turf.
For turf professionals, early-season weed prevention means:
- Cleaner playing surfaces
- Improved turf density
- Reduced in-season rescue applications
- More predictable program performance
Key Factors When Selecting a Pre-Emergent
Not all pre-emergents perform the same across every site. Choosing the right active ingredient and formulation helps you match weed pressure, turf tolerance, and timing windows - so you get consistent control without compromising playability or establishment plans. When selecting a product, consider:
- Turf type (greens, fairways, sports fields, residential/commercial lawns)
- Nutrient requirements
- Desired residual length
- Application timing flexibility
- Insect pressure
- Seeding plans
The Andersons herbicide portfolio is built on proven active ingredients, differentiated by formulation quality and delivery technology. From proprietary premixes to DG lite carriers, these products are designed to improve handling, dispersion, and on-turf performance. Below is the complete pre-emergent offering featured in our professional catalog:
Barricade® (Prodiamine) Products
Barricade (prodiamine) is a proven, long-residual pre-emergent option most commonly used in residential and commercial lawn care programs. Our DG Technology helps deliver even coverage and rapid dispersion into the soil profile, stopping 30+ grassy and broadleaf weeds before they emerge.
Available Products:
Dimension® (Dithiopyr) Products
Dimension (dithiopyr) is a strong fit for residential/commercial lawn care and golf course programs when you want reliable pre-emergent control plus a little more timing flexibility. Beyond preventing crabgrass and other annual grasses, dithiopyr offers early post-emergent activity on young crabgrass - making it a smart option if your application window is pushed later or you’re trying to reduce early breakthrough pressure. Choose Dimension when crabgrass performance and application-window forgiveness matter more than the longest possible residual.
Available Products:
- 0.25% Dimension on DG Pro®
- 14-0-14 + 0.164% Dimension
- 18-3-12 + 0.164% Dimension
- 15-0-10 + 0.25% Dimension
Dimension (Dithiopyr) Products for Greens
Available Products:
- 0-0-5 + 0.103% Dithiopyr on DG Pro®
A low-nitrogen, light-feeding option for turf areas where you want dithiopyr pre-emergent performance without pushing growth. - 10-3-10 + 0.164% Dithiopyr
A balanced fertility + pre-emergent choice when you want to pair crabgrass prevention with a moderate spring feed in one application.
- 18-6-15 + 0.164% Dithiopyr
A higher-nitrogen, more aggressive feed-and-prevent option when you want noticeable green-up alongside dithiopyr protection early in the season.
Dimension (Dithiopyr) + Acelepryn® (Chlorantraniliprole) Products
This combination is designed for programs that want to cover two early-season priorities in one pass: crabgrass prevention with Dimension plus preventive insect control with Acelepryn. It’s most often used in lawn care and golf course settings where grub/armyworm pressure is a known annual issue and a single granular application helps simplify spring operations. Choose it over Dimension-only when insect pressure justifies the added value; choose it over insecticide-only options when you also need a pre-emergent foundation for annual grass control.
Available Products:
- 0-0-8 + 0.167% Dimension + 0.067% Acelepryn
- 13-0-3 + 0.167% Dimension + 0.067% Acelepryn
- 24-0-6 + 0.167% Dimension + 0.067% Acelepryn
- 24-0-10 + 0.167% Dimension + 0.067% Acelepryn
Ronstar® (Oxadiazon) Products
Ronstar (oxadiazon) is typically selected for warm-season and transition-zone turf for golf courses and sports field programs, especially in the South, where annual grass pressure (including goosegrass) is a recurring challenge and granular pre-emergent performance is preferred. Compared to prodiamine or dithiopyr, oxadiazon is often chosen for its fit on certain warm-season areas and for operations that want a stable, dust-free granular that spreads evenly and stays where it’s applied. All Ronstar products use SFT™ hot-melt formulation technology to create a uniform, low-dust granule for consistent coverage and handling.
Available Products:
- Oxa-Pro® 2G
- 5-0-15 + 1% Ronstar
- 22-0-0 + 1% Ronstar
- 22-4-11 + 1% Ronstar

ProPendi® (Pendimethalin) Products
ProPendi (pendimethalin) is a practical, budget-friendly pre-emergent that’s most often used in lawn care programs where you want dependable annual grass prevention in a granular application. It provides strong prevention of crabgrass and other annual grasses with added broadleaf suppression, making it a solid foundation product for early-season applications or for rotating actives as part of a resistance-management strategy. Choose ProPendi when you need reliable, straightforward control at a strong value - especially when ultra-long residual (prodiamine) or the added timing flexibility of dithiopyr isn’t required.
Available Product:
Pre-Emergent Herbicides for Seeding (Mesotrione)
Designed for new seeding and renovation windows, mesotrione helps suppress key weeds during establishment without the stand-reduction risk associated with many traditional pre-emergents. This makes it a go-to choice for golf courses, sports fields, and lawn care programs when early-season weed control and successful germination are needed at the same time.
Available Product:
Specialty Pre-Emergent Products
For specific weed challenges and niche applications:
- Tricept® 2.5 DG (Trifluralin + Isoxaben)
Best for landscape beds and ornamentals where you need broad-spectrum pre-emergent control, especially strong on small-seeded broadleaf weeds. - 5% Treflan® on DG Pro® (Trifluralin)
A solid fit for ornamental and nursery areas where trifluralin is desired for annual grass control and you want a convenient granular carrier for even coverage. - Goosegrass Crabgrass Control (Bensulide + Oxadiazon)
Designed for golf course greens and tees, it provides goosegrass control with excellent safety on sensitive, closely managed turf where injury risk is a key concern.
- Grass Guard™ DG 9-0-0 (Corn gluten meal-based)
An alternative, corn gluten meal-based option for programs that prefer a more natural approach and are comfortable with lighter, incremental weed suppression over time.
These solutions provide targeted control for ornamental beds, difficult annual grasses, and specialized turf programs.
With options that span long-residual barriers, timing-flexible actives, warm-season specialty solutions, and seeding-safe mesotrione, you can build a pre-emergent program that fits your turf and your calendar. Start by identifying your primary weed targets and application window, then select the active ingredient and carrier that best match the site’s tolerance and performance expectations. The result is cleaner turf, fewer rescue applications, and more consistent season-long outcomes.
