Factor 1. Product Overview

Pasture Pro and Grazon are herbicides specifically formulated for pasture management. While they share a common purpose, their composition and active ingredients differ, which can influence their performance and suitability for various situations.


Factor 2. Target Weeds

Pasture Pro primarily targets broadleaf weeds such as dandelions, thistles, and ragweed. It provides effective control against these common pasture invaders.

Grazon, on the other hand, offers a broader spectrum of control, targeting both broadleaf weeds and certain woody plants like brush and trees.

Factor 3. Effectiveness

In terms of effectiveness, both Pasture Pro and Grazon have proven track records. However, the choice between the two depends on the specific weed species you are dealing with.

If your primary concern is broadleaf weeds, Pasture Pro may be sufficient. But if you also need to tackle woody plants, Grazon offers a more comprehensive solution.

Factor 4. Application

When it comes to application, both products are available in liquid form and can be easily sprayed on the target areas.

They can be applied using various equipment, such as backpack sprayers or tractor-mounted sprayers. Always follow the manufacturer’s instructions for proper application rates and techniques.

Factor 5. Mixing Ratio

  • Pasture Pro: The mixing ratio for Pasture Pro may vary based on the specific formulation and desired weed control. It typically requires mixing with water at a specified ratio, such as 1 to 2.5 fluid ounces of product per gallon of water.
  • Grazon: The mixing ratio for Grazon can also depend on the formulation and target weeds. It is usually mixed with water at a certain ratio, such as 1 to 2 fluid ounces of product per gallon of water.

Factor 6. Safety

Safety is of utmost importance when working with herbicides. Both Pasture Pro and Grazon require proper handling and precautions.

It is crucial to use personal protective equipment (PPE) such as gloves, goggles, and masks when applying these products. Follow the safety guidelines provided by the manufacturers to minimize risks.

Factor 7. Residual Activity

Residual activity refers to how long the herbicide remains effective after application. Pasture Pro has a relatively short residual activity, typically requiring more frequent applications for long-term weed control.


Grazon, on the other hand, provides a longer-lasting effect, reducing the need for frequent reapplication.

Factor 8. Rainfastness

Rainfastness is the ability of an herbicide to withstand rainfall shortly after application. It is an essential factor to consider, especially in areas prone to sudden showers.

Pasture Pro offers good rain fastness, ensuring that it remains effective even after exposure to rain. Grazon also has excellent rainfast properties, providing reliable performance under wet conditions.

Factor 9. Grazing Restrictions

If you have grazing animals, it is crucial to consider any grazing restrictions associated with the herbicides. Pasture Pro has a relatively short grazing restriction period, allowing animals to return to the treated area relatively quickly.

Grazon, however, has a longer grazing restriction, requiring a waiting period to ensure the safety of the animals.

Factor 10. Environmental Impact

As responsible land stewards, it is important to consider the environmental impact of the products we use.

Both Pasture Pro and Grazon have specific guidelines regarding their use near water bodies, such as streams or ponds, to prevent contamination. Follow these guidelines to minimize any negative impact on the environment.

Factor 11. Cost-Effectiveness

Cost-effectiveness is an essential aspect to consider when choosing between herbicides. The pricing of Pasture Pro and Grazon can vary depending on factors such as product size and location.

It is advisable to compare prices from different suppliers and evaluate the cost-effectiveness based on the specific requirements of your pasture management program.

Pasture Pro vs Grazon: Which One to Choose?

Choosing between Pasture Pro and Grazon depends on various factors, including the types of weeds you need to control, the desired residual activity, grazing restrictions, and cost-effectiveness. Assess your specific needs and consider the factors discussed in this article to make an informed decision.

Remember to always follow the product labels and guidelines provided by the manufacturers for optimal results and safety.
