Triclopyr was first registered for forestry use in 1979 and is currently used in both agricultural and non-agricultural settings. With widespread use, there are over 200 products that contain triclopyr. As always, it is important to read the label, as it is the law and make sure the product you purchase has a forestry label and is labeled for your intended use.<\/p>\n\n\n\n

Triclopyr is a systemic herbicide that mimics the plant hormone auxin. This causes uncontrolled, disorganized plant growth, leading to a slow death, typically within weeks. Broadleaf herbs and woody species are the target species, making triclopyr a selective herbicide. There are two basic formulations used in forestry: triethylamine salt (commonly known as Triclopyr 3) and butoxyethyl ester (commonly known as Triclopyr 4). Triclopyr 3 is water-soluble, whereas triclopyr 4 is oil-soluble (bark treatments) and water-soluble (foliar treatments). Triclopyr 4 can volatilize at temperatures above 85\u00b0 F. Triclopyr 3 does not have that risk. Neither formulation has soil activity.<\/p>\n\n\n\n

Triclopyr can be used in all facets of forest management. It is commonly used in site preparation tank mixes, conifer release (directed spray application), mid-rotation vegetation control, and spot treatments for invasive species and other competitive vegetation. With conifer release, one needs to read the label on the application because triclopyr can kill pines. Application techniques range from basal bark, cut-stump, foliar, and hack-and-squirt. For basal bark applications, one would use butoxyethyl ester.<\/p>\n\n\n\n

As with any herbicide, I would recommend contacting your local Extension Agent. It is important to identify the weeds you want to control, the crop trees you want to protect, and any sensitive areas that do not need to be sprayed.<\/p>\n\n\n\n

South Carolina Hardwood Pulpwood Prices Show Mixed Trends<\/strong><\/p>\n\n\n

Figure 1. Compared to the third quarter of 2025, pine pulpwood prices declined by approximately 10%, while hardwood pulpwood prices increased by about 40%. Puskar Khanal, Clemson Univeristy.<\/figcaption><\/figure>\n<\/div>\n\n\n

In the fourth quarter of 2025, the average statewide stumpage prices for pine and hardwood pulpwood in South Carolina were $5.00 per ton and $6.30 per ton, respectively. Compared to the third quarter of 2025, pine pulpwood prices declined by approximately 10%, while hardwood pulpwood prices increased by about 40%. This substantial percentage increase for hardwood pulpwood should be viewed in the context that prices reached their lowest level in the prior quarter before this recent rebound. Following the increase, hardwood pulpwood prices have returned to levels like those at the beginning of 2025, whereas pine pulpwood prices have continued to trend downward.<\/p>\n\n\n\n

Both pine and hardwood pulpwood prices remain at lower levels relative to the past three years. Overall, pulpwood prices in 2025 have been disappointing for South Carolina forest landowners, as weak market conditions have persisted throughout the year with limited signs of meaningful recovery, particularly in the pine pulpwood segment.<\/p>\n\n\n\n

South Carolina Sawtimber Prices Show Mixed Trends<\/strong><\/p>\n\n\n

Figure 2. Compared to the third quarter of 2025, pine sawtimber prices declined by about 20%, while hardwood sawtimber prices increased by about 9%. Puskar Khanal, Clemson University.<\/figcaption><\/figure>\n<\/div>\n\n\n

In the fourth quarter of 2025, statewide average stumpage prices for pine and hardwood sawtimber in South Carolina were $18.40 per ton and $17.40 per ton, respectively. Compared to the third quarter of 2025, pine sawtimber prices declined by about 20%, while hardwood sawtimber prices increased by about 9%. Both pulpwood and sawtimber stumpage prices for pine trees fell during the quarter, reflecting the emerging impacts of recent mill closures on local demand and stumpage values. Hardwood sawtimber prices rebounded slightly from their low point in the prior quarter, though they remain below levels observed at the beginning of 2025. Overall, pine sawtimber prices declined by roughly 20% year-to-date, while hardwood sawtimber prices fell by about 9% compared to the start of the year.<\/p>\n\n\n\n

In summary, the sawtimber stumpage market in South Carolina remained challenging for forest landowners throughout 2025, with persistently low prices. While hardwood prices showed some modest improvement, they stayed near multi-year lows. Pine sawtimber prices continued a steady downward trend over the years, underscoring a difficult market environment statewide influenced by mill closures and broader demand pressures.<\/p>\n\n\n\n

Wood Market is Local<\/strong><\/strong><\/p>\n\n\n\n

Stumpage prices for both sawtimber and pulpwood in your local markets could vary significantly as compared to the above statewide averages depending on: size and species composition, quality of timber, total acres and volume, logging operability, distance from nearby mills, and overall market condition.<\/p>\n\n\n\n

When I visit with landowners, I have noticed thickets of thorny olive (Elaeagnus pungens<\/em>) and\/or autumn olive (Elaeagnus umbellata<\/em>) throughout woodlands, especially in bottom lands. It was introduced from China and Japan in the 1830s and was widely planted for wildlife habitat and ornamental purposes. While animals do like the fruits from these olives, they outcompete our native plants, and they are listed as a non-native invasive species. American Beautyberry is a good native alternative to olives and benefits wildlife.<\/p>\n\n\n\n

Thorny olive and autumn olive can look similar to one another, but they do have some differences that help with identification. Thorny olive is an evergreen shrub that will grow between 3 to 25 feet in height. The branches have thorns scattered with thick leaves that are silver-brown on their underside. Autumn olive is a deciduous shrub that grows 3 to 20 feet in height. It will also have scattered thorns along the branches, with a silvery underside to the leaves.<\/p>\n\n\n\n

The leaves of the thorny olive are alternate and oval to elliptic. The leaves range in size from 0.4 to 4 inches long. The margins are irregular and wavy. Autumn olive leaves range from 2-3 inches long and all the leaves will be elliptic in shape.<\/p>\n\n\n

The timing of the flowers and fruit can also help in identification. Thorny olive flowers from October to December, while autumn olive flowers from February to June. Fruits of the thorny olive will set from March to June, while the autumn olive sets its fruit from August to November.<\/p>\n\n\n\n
