Pre-emergent herbicides are an effective way to control weeds by preventing their seeds from germinating. The cost of pre-emergent herbicides can vary widely based on factors such as brand, formulation, and the size of the area you need to treat. On average, you can expect to pay between $20 and $50 for a product that covers 5,000 to 10,000 square feet.
What Affects the Cost of Pre-Emergent Herbicides?
1. Brand and Quality
The brand and quality of a pre-emergent herbicide significantly influence its price. Premium brands often offer enhanced effectiveness and longer-lasting results, which can justify a higher cost. Popular brands such as Scotts, Bayer, and Ortho are known for their reliable products.
2. Formulation Type
Pre-emergent herbicides come in various formulations, including granular and liquid forms. Granular options are typically easier to apply and may be less expensive, while liquid formulations can provide more uniform coverage but might require additional equipment for application.
3. Coverage Area
The size of the area you need to treat will also affect the cost. Products are often sold based on the square footage they cover. Larger coverage options tend to offer better value per square foot but come at a higher upfront cost.
4. Active Ingredients
Different products contain varying active ingredients, which can impact pricing. Common active ingredients include prodiamine, pendimethalin, and dithiopyr. These ingredients vary in their effectiveness against different types of weeds and their longevity.

How to Choose the Right Pre-Emergent Herbicide
Consider Your Lawn Type and Weed Problems
Before selecting a pre-emergent herbicide, consider the types of weeds you are dealing with and the specific needs of your lawn. Some products are more effective against grassy weeds, while others target broadleaf varieties.
Evaluate Application Timing
Timing is crucial for pre-emergent herbicides to be effective. Most should be applied in early spring or fall, before weed seeds begin to germinate. Check the product instructions for the best application window.
Assess Your Budget
Determine your budget and weigh it against the benefits each product offers. While more expensive options might provide longer-lasting results, they may not always be necessary for smaller or less problematic areas.
Practical Tips for Using Pre-Emergent Herbicides
- Read the Label: Always follow the manufacturer’s instructions for application rates and safety precautions.
- Use Proper Equipment: For liquid formulations, ensure you have a suitable sprayer. Granular products may require a spreader for even distribution.
- Water After Application: Most pre-emergents need to be watered in to activate. Check the label for specific requirements.
