I’ve tested a bunch, and these are the pre-emergents that have actually worked for me here in North Texas.

Prodiamine 65 WDG is a powerhouse when it comes to pre-emergent weed control. This water-dispersible granule formula provides a long-lasting barrier in your soil, preventing a wide range of weeds from germinating. It’s a favorite among lawn care professionals for its effectiveness and cost-efficiency.
Pros:

2. Dithiopyr 40 WSG
Dithiopyr 40 WSG is another excellent pre-emergent, particularly effective against crabgrass. This water-soluble granule formulation not only prevents weed seeds from germinating but also offers some post-emergent control on very young weeds. This dual action can be a lifesaver if you missed your application window slightly.
Pros:

- ✅ Offers some early post-emergent activity.
- ✅ Water-soluble formula ensures even distribution.
Cons:
- ❌ May require more frequent applications compared to Prodiamine.

Verdict: Dithiopyr 40 WSG is a great choice if crabgrass is your primary concern, especially if you want a bit of insurance against late germinators. It’s a solid option for those willing to pay a premium for the added post-emergent benefit.
3. Dimension 2EW
Dimension 2EW is a popular pre-emergent herbicide known for its effectiveness and ease of use. The “EW” stands for Emulsifiable Concentrate, meaning it mixes readily with water. It offers a good balance between pre- and early post-emergent control, making it forgiving if you’re a little late with your application. I’ve had good luck with it on dandelion seedlings.
Pros:
- ✅ Effective pre-emergent control of many common lawn weeds.
- ✅ Offers post-emergent control on young, susceptible weeds.
- ✅ Easy to mix and apply.
Cons:
- ❌ Can be less effective on certain weed species compared to other options.

- ❌ Can be harmful to aquatic life if it runs off into waterways.
Verdict: Dimension 2EW is a user-friendly option that provides good overall weed control, especially if you value the added post-emergent benefit. It’s a solid choice for homeowners looking for convenience and reliability.
4. Corn Gluten Meal
For those seeking an organic approach to weed control, Corn Gluten Meal is a viable option. It works by releasing organic compounds that inhibit root formation in germinating weed seeds. It’s a natural product, making it safe for pets and children, but it requires a different approach than synthetic herbicides. It’s not as potent as the chemical options, but it’s a good start if you’re going organic.
Pros:
- ✅ Organic and environmentally friendly.
- ✅ Safe for pets and children.
- ✅ Can also act as a slow-release fertilizer.
Cons:

- ❌ Can be expensive compared to other options.
Verdict: Corn Gluten Meal is best suited for homeowners committed to organic lawn care practices. It requires patience and diligence but can be a worthwhile option for those prioritizing natural solutions.
5. Barricade Granules
Barricade Granules are a popular choice for pre-emergent weed control due to their ease of use. This granular formulation can be applied with a fertilizer spreader, making the application process simple and straightforward. The granules release the active ingredient slowly, providing a consistent barrier against weed germination.
Pros:
- ✅ Easy to apply with a standard fertilizer spreader.
- ✅ Provides consistent, long-lasting weed control.
- ✅ Less likely to stain concrete compared to liquid formulations.
Cons:
- ❌ Can be more expensive than concentrated liquid or powder formulations.
- ❌ Requires rainfall or irrigation to activate the herbicide.
- ❌ Can be less precise than liquid applications, potentially missing spots.
Verdict: Barricade Granules are an excellent choice for homeowners who prioritize ease of application and consistent weed control. It’s a good option if you have a larger lawn and prefer using a spreader.
Buying Guide
Choosing the right pre-emergent for your North Texas lawn involves a few key considerations. Here’s what to keep in mind:
- Weed Type: Identify the specific weeds you’re trying to prevent. Some pre-emergents are more effective against certain weed species than others. Crabgrass, for example, is a common problem, so choose a product known to control it.
- Timing: Apply pre-emergent before weed seeds germinate. In North Texas, this typically means applying in early spring (February-March) and again in the fall (September-October). Soil temperature is a better indicator than calendar dates. Aim for when the soil temperature at a 2-inch depth reaches 55°F for several consecutive days in the spring.
- Formulation: Pre-emergents come in liquid, granular, and powder formulations. Liquids require mixing and spraying, while granules can be applied with a spreader. Powders need to be mixed with water. Choose the formulation that best suits your equipment and comfort level.
- Active Ingredient: Common active ingredients include Prodiamine, Dithiopyr, and Benefin. Each has its own strengths and weaknesses. Research which ingredient is most effective against your target weeds.
- Application Rate: Follow the manufacturer’s instructions carefully regarding application rates. Over-application can damage your lawn, while under-application may not provide adequate weed control.
- Watering: Most pre-emergents require watering in after application to activate the herbicide. Check the product label for specific instructions.
- Lawn Type: Consider your grass type when choosing a pre-emergent. Some herbicides can harm certain types of grass. Always read the label to ensure the product is safe for your lawn.
- Pet and Child Safety: If you have pets or children, choose a pre-emergent that is safe for them. Organic options like corn gluten meal are generally safer than synthetic herbicides.
FAQs
Q: When is the best time to apply pre-emergent in North Texas?
A: Early spring (February-March) and early fall (September-October) are typically the best times. Monitor soil temperatures and apply when the soil at a 2-inch depth reaches 55°F for several consecutive days in the spring.
Q: How do I apply granular pre-emergent?
A: Use a fertilizer spreader and follow the manufacturer’s instructions for the correct application rate. Water the granules in after application to activate the herbicide.
Q: Can I apply pre-emergent and fertilizer at the same time?
A: Yes, some products combine pre-emergent herbicides with fertilizer. This can save you time and effort. Just be sure the product is suitable for your lawn type and follow the application instructions carefully.
Q: Is pre-emergent safe for pets?
A: Many pre-emergents are safe for pets once they have been watered in and the treated area has dried. However, it’s always best to keep pets off the lawn during application and until the product is fully activated. Organic options like corn gluten meal are generally safer.
Q: What if I miss the pre-emergent application window?
A: If you miss the pre-emergent window, you can use a post-emergent herbicide to control existing weeds. Some pre-emergent products, like those containing Dithiopyr, also offer some early post-emergent activity.
