Restoration & Management

HomeWhat is Longleaf?Restoration & ManagementHerbicides

Herbicides

In addition to prescribed fire, land managers are increasingly turning to herbicides for managing competition in forest lands. In some situations, such as elimination of invasive exotic plant species like cogongrass, selective herbicides are the only tools that will achieve successful results.

Herbicide is a powerful tool, but it is important to use the right chemical for the job. Read the label and make sure the active ingredient will not negatively impact planted longleaf and/or any desirable groundcover species that occur in the treated area.

For more in-depth information about herbicide use, please consider attending our Longleaf 201 - Herbicides & Longleaf Academy.

Since its inception in 1995, The Longleaf Alliance Since its inception in 1995, The Longleaf Alliance has used science-based outreach, partnership engagement, and on-the-ground assistance to support longleaf restoration, stewardship, and conservation across the Southeast.For #NationalNonprofitDay, we want to say thank you to all our supporters and partners (many of which are also non-profits). Without you we could not do all that we do! Help us celebrate the day by sharing a non-profit that means something special to you. Tag us in the post so we can like/share/follow their work too 😊

Cogongrass is a BIG problem in the Southeast - inc Cogongrass is a BIG problem in the Southeast - including longleaf pine habitats. It is a tricky species to eradicate, but there are options. Some more effective than others.What doesn't work? Mowing, burning, and grazing. Here is why – 75% of cogongrass is underground in its rhizomes and roots. Removing only the top 25% of this species simply encourages it to regrow and spread. Its high silica content means it not only makes lousy forage, but it also increases its probability of igniting. Cogongrass fires are intense, with typical flame lengths doubling the height of the grass.So what does work?Effective chemical control of cogongrass can be achieved with glyphosate, a foliar active herbicide. Even though this is not a selective herbicide, applying glyphosate only to the cogongrass leaves will target this invasive without harming your mid to upper-story species. Other treatment options include imazapyr, tilling, and combining strategies like mowing and fire with herbicide treatments.Summertime (May to October depending by one’s location) is the best time to treat cogongrass. Be prepared to re-treat, as cogongrass does not give up easily and can take up to five re-treatments for confirmed eradication. For more information, check out our Longleaf Leader article (link in bio).
Georgia landowners - Please spread the word about Georgia landowners - Please spread the word about this free workshop (and meal) in Emanuel County on August 1st. RSVPs are needed by tomorrow - Friday, July 28th - so reserve your spot today! Details at longleafalliance.org > events (link in bio).
