❓ FAQs — Herbicides Containing Clopyralid

1. What is clopyralid and why is it used in herbicides?

Clopyralid is a selective systemic herbicide designed to control tough broadleaf weeds, especially thistles, clover, docks, and knapweed. It works by mimicking plant hormones, forcing weeds into uncontrolled growth that leads to death. Because it moves deep into roots, it is especially effective against perennial weeds. This makes it ideal for pastures, turf, rights-of-way, and agricultural fields.

2. Is clopyralid safe for grass?

Yes, clopyralid targets broadleaf plants, not grasses. This selectivity makes it highly valued for pasture, turf, and cereal crop applications. When used correctly, it does not harm desirable grass species. However, label instructions must be followed to avoid drift onto sensitive crops.

3. Which weeds does clopyralid control best?

Clopyralid is most effective against Canada thistle, knapweed, mallow, burdock, clover, and docks. These weeds typically have deep roots and are resistant to weaker herbicides. The active ingredient eliminates both shoots and roots, reducing regrowth. Its systemic nature provides long-term suppression.

4. Can clopyralid herbicides be used around gardens or ornamentals?

No—clopyralid can severely injure or kill many ornamental and garden species. Even small amounts of drift can cause long-term damage. It should not be used near sensitive broadleaf plants, vegetables, shrubs, or flowers. Gardeners must maintain strict buffer zones.

5. How long does clopyralid remain active in soil?

Clopyralid has a moderate to long soil residual depending on climate and soil type. In some cooler regions, it may persist for months. This allows extended weed suppression but also restricts rotational planting. Always follow label guidelines on reseeding intervals.

6. Can clopyralid be mixed with other herbicides?

Yes, clopyralid is commonly tank-mixed with actives like 2,4-D, triclopyr, metsulfuron, or florasulam. These combinations broaden weed control and enhance effectiveness. Tank mixes should be done only according to label directions. Compatibility charts ensure safe mixtures.

7. Are clopyralid herbicides restricted-use products?

Most clopyralid formulations are not classified as restricted-use products, though regulations vary by country. Some regions impose limitations due to environmental persistence. Professional applicators may require certification for certain mixes. Always check local laws before purchasing.
