Are you looking for a pre-emergent herbicide to control weeds in your lawn or landscape? If so, prodiamine might be the answer. But how much prodiamine should you use per gallon of water? In this comprehensive guide, we will cover everything you need to know about prodiamine, its application rates, and the best practices to get maximum results.

What is Prodiamine?

Prodiamine is a pre-emergent herbicide that controls the growth of weeds by inhibiting the development of their root system. It is specially designed to control annual grasses and broadleaf weeds in turfgrass, ornamental areas, and golf courses.

Prodiamine is available in different formulations, including WDG (water-dispersible granule), liquid concentrate, and dry flowable.

What is the Appropriate Amount of Prodiamine per Gallon?

The appropriate amount of prodiamine per gallon of water depends on the type of application, the target weed species, and the desired level of weed control. In general, the maximum application rate of prodiamine is 2.4 pounds of active ingredient per acre per year, which translates to 0.

However, the actual amount of prodiamine per gallon may vary depending on the size of the area to be treated, the type of spray equipment used, and the concentration of the prodiamine formulation. To determine the exact amount of prodiamine per gallon, refer to the product label or consult with a professional applicator.

When is the Best Time to Apply Prodiamine?

The best time to apply prodiamine depends on the type of weed and the stage of its development. In general, prodiamine is most effective when applied before weed seeds germinate, which is known as pre-emergent weed control.

For warm-season grasses, the best time to apply prodiamine is early spring, when the soil temperature reaches 55°F for four consecutive days. For cool-season grasses, the best time to apply prodiamine is in the fall or late winter, when the soil temperature drops below 50°F.

How Much Prodiamine for Larger Applications?

For larger applications, such as golf courses or commercial landscapes, a professional spray rig or skid sprayer is recommended. The appropriate amount of prodiamine per gallon for larger applications may vary depending on the type of equipment used, the spray volume, and the target weed species.

In general, a maximum rate of 2.4 pounds of active ingredient per acre per year should not be exceeded.

How Much Prodiamine for Smaller Applications?

For smaller applications, such as home gardens or container-grown landscape ornamentals, a handheld pump sprayer or weed-hoe may be used. The appropriate amount of prodiamine per gallon for smaller applications may vary depending on the size of the area to be treated and the concentration of the prodiamine formulation.

In general, a smaller amount of prodiamine per gallon, such as 0.5 ounces or 1 tablespoon, may be used.

How Does Prodiamine Work?

Prodiamine works by inhibiting the development of the root system in weed seeds, preventing them from germinating and growing. It is a selective herbicide that targets annual grasses and broadleaf weeds, leaving established turfgrass and ornamental plants unharmed.

Prodiamine is a pre-emergent herbicide, which means it must be applied before weed seeds germinate to be effective.

What are the Benefits of Prodiamine?

Prodiamine offers several benefits for weed control in lawns and landscapes. It provides residual control of weeds for up to several months, reducing the need for frequent applications. It is selective, meaning it targets only the undesirable weed species while leaving the desired plants unharmed.

It is also easy to apply and available in different formulations to fit any application need.

What are the Risks of Prodiamine?

Like any herbicide, prodiamine poses some risks to humans, pets, and the environment if not used properly. It is toxic if ingested or inhaled and can cause skin irritation or allergic reactions. It is also harmful to aquatic organisms and should not be applied near bodies of water.

To minimize the risks of prodiamine, always read and follow the product label instructions carefully and wear protective clothing and equipment.

Conclusion

In conclusion, prodiamine is an effective pre-emergent herbicide for controlling weeds in lawns and landscapes. The appropriate amount of prodiamine per gallon depends on the type of application, target weed species, and desired level of weed control.

To get maximum results, always follow the product label instructions and consult with a professional applicator when in doubt.
