Understanding Doveweed and its Persistence in Florida

Doveweed (Murdannia nudiflora) is a common and persistent weed plaguing Florida lawns and gardens. Its rapid growth and prolific seed production make it a challenging weed to manage. This resilient weed thrives in warm, humid climates, making Florida the perfect breeding ground. Effective control requires a strategic approach.

Glyphosate (Roundup) for Doveweed Control: Does it Work?

Glyphosate, the active ingredient in many popular herbicides like Roundup, is a non-selective herbicide. This means it kills all plants it contacts, not just weeds. While effective on doveweed, its non-selective nature requires careful application to avoid damaging desirable plants.

Does it kill doveweed? Yes, glyphosate can effectively kill doveweed. However, success depends on several factors, including the application method, the stage of doveweed growth, and environmental conditions. Young, actively growing doveweed is more susceptible to glyphosate than mature, established plants.

How to Effectively Use Glyphosate on Doveweed:

Timing is Key: Apply glyphosate when the doveweed is actively growing and weather conditions are favorable (avoiding rain for at least 24 hours).
Application Method: Use a spot treatment method to minimize damage to desirable plants. A pump sprayer or even a small watering can with a nozzle can work well for small infestations.
Proper Dilution: Always follow the manufacturer's instructions for dilution rates. Using too little may be ineffective, while using too much can damage the environment and potentially harm surrounding plants.
Leaf Coverage: Ensure thorough coverage of the doveweed leaves. Glyphosate is a systemic herbicide; it needs to be absorbed by the plant's leaves to be effective.

Factors Affecting Glyphosate Effectiveness on Doveweed

Weed Density: In dense infestations, multiple applications might be needed.
Weather Conditions: Heavy rain immediately after application can wash away the herbicide, reducing its effectiveness.
Soil Conditions: The soil type can affect herbicide absorption.
Doveweed Resistance: There are reports of glyphosate resistance developing in some weed populations. This means repeated use of glyphosate may become less effective over time.

Alternative Doveweed Control Methods in Florida

While glyphosate can be effective, it's not always the ideal solution. Consider these alternatives:

Pre-emergent Herbicides: These prevent weed seeds from germinating. Applying a pre-emergent herbicide in the fall or spring can help reduce doveweed emergence.
Cultural Control: This involves improving overall lawn health. Healthy, thick turfgrass competes with weeds, reducing their chances of establishment. Proper mowing height, fertilization, and watering practices help achieve this.
Hand-Pulling: For small infestations, hand-pulling doveweed can be an effective and eco-friendly method. Be sure to remove the entire root system to prevent regrowth.
Post-Emergent Herbicides (Alternatives to Glyphosate): Several post-emergent herbicides are available that target broadleaf weeds like doveweed. Consult with your local garden center or extension office for recommendations specific to your region.

Preventative Measures for Doveweed Control

Regular Lawn Maintenance: Maintain a healthy lawn to outcompete weeds. This includes proper mowing, fertilization, and watering.
Thatch Removal: Thatch build-up can provide a haven for weed seeds. Regular thatch removal improves air and water circulation, reducing weed growth.
Mulching: In garden beds, using a thick layer of mulch can suppress weed growth.

Conclusion: Glyphosate and Doveweed in Florida

Glyphosate can effectively control doveweed in Florida, but careful application and consideration of alternative methods are crucial. Remember that a comprehensive approach combining preventative measures, appropriate herbicide use, and alternative control techniques is generally most effective for long-term doveweed management in your Florida landscape. Always read and follow the manufacturer's instructions on all herbicide products.
