This treatment may take a few months to kill privet but it is very effective. However, with the correct approach and diligent follow-up treatments, privet can be effectively controlled. This is not, however, exhaustive as certain herbicides used in forestry and rights-of-way are not covered. If the privet is taller than 6 to 8 feet, consider using other methods such as brush mulching, basal bark, or cut stump treatment. Both water- and oil-based cut stump treatments work on any size privet, but it is critical to treat every cut stem. Privet (Ligustrum spp.) This method entails spraying the entire circumference of the bottom 12 to 15 inches of each stem with an oil soluble herbicide (Figure 7). Researchers say you can achieve great control with much less herbicide than typically used. Do not use glyphosate formulations that are called “Ready to Use” because they generally do not contain enough glyphosate to be effective. The 1/128 Calibration Method for Backpack Sprayers, Latest on Toxicants for Controlling Wild Pigs, Alabama Cooperative Extension System, Posted by: Stephen Enloe, Nancy Loewenstein. They can shade out and exclude native understory species, perhaps even reducing tree recruitment. No single treatment will eradicate privet. For example, Chinese privet has become well established in southeastern forests and continues to spread. Following privet control, many factors influence which species naturally recolonize the site. Figure 4. Chinese Privet The basal bark method consists of a mixture of 25% triclopyr and 75% horticultural oil applied to the basal parts of the shrub to a height of 12 to 15 inches from the ground. The Alabama Several mechanical control options, such as hand pulling, mowing, or cutting, may be effective, but to effectively eliminate this plant the roots must be removed. While privet seeds in the soil seed bank only survive for about one year, birds and flooding can reintroduce seed into the area. Glyphosate treatments applied in the spring and summer may not provide effective control and the risk of damage to surrounding vegetation is much greater. However, it can be integrated with cut stump or foliar herbicide treatments described below. They quickly remove dense stands of privet, providing immediate access to an area. A 2% solution of glyphosate or … This creates a good setup for a late fall foliar treatment with the herbicide glyphosate. To direct this process of recolonization and site restoration, land managers may choose to actively plant desired species. Grazing is usually not an option for Chinese tallowtree control. Chinese privet (Ligustrum sinense) is a shrub with thin opposite leaves, semievergreen to evergreen, and thicket forming to 30 feet in height.They have multiple leaning-to-arching stems with long, leafy branches. Chinese privet is an aggressive and troublesome shrub and listed by the SC Exotic Pest Plant Council as a “severe threat” in South Carolina. In addition to sunlight and moisture availability, these factors include surrounding vegetation and prior land use.
Arundinaria gigantea (giant cane) is a native bamboo species that used to be very abundant in riparian and wetland ecosystems in the region. To tackle narrow-leaf privet: control mature trees to reduce seed production; check for new seedlings; control young plants before they produce seed Chinese privet ( Ligustrum sinense) and other invasive privets in the genus Ligustrum are a serious problem for many homeowners, farmers, foresters, and land managers in Alabama. Dispose of it away from your landscape. Chinese privet spreads rapidly both from root sprouts and seed, and it can quickly overtake desirable grasses and dominate a larger and larger portion of a pasture or hayfield each year. Whatever the method of herbicide application, landowners should be prepared for … No differences were found in August comparisons of liquid versus dry glyphosate products or water-soluble versus oil-soluble triclopyr products for each of the four rates (study 2). Figure 2. This content printed from the website located at: This website would like to use cookies to collect information to improve your browsing experience. This method entails cutting followed by application of an herbicide to the surface of the stump. Methods of control may be “cultural, preventative, manual, and mechanical removal, biological control, physical controls, and herbicides” or combinations of these. that ensures all people have access to information that improves their quality of life Ideally, you can burn it. Drift, however, can be a serious problem, especially on windy days. and economic well-being. When discussing characteristics common to all 4 species, this report refers to them collectively as privet or privets. Chinese privet is a nonnative shrub that has invaded mesic forests throughout the southeastern United States during the past century. The first step in preventative control of privet is the removal of existing plants within the landscape and to limit planting. These are applied to stumps at full strength. A spray indicator helps keep track of what has been treated. Total eradication is extremely difficult with well-established plants. However, privet control was not influenced by variation in herbicide rates of 1.7, 3.4, 5.0, or 6.7 kg a.e./ha compared with each of the five application timings. The Act requires everyone to take all reasonable and practical steps to minimise the risks associated with invasive plants and animals under their control. If replanting, continued monitoring and spot treatment of new privet is critical as there are no known plant communities in the southeastern United States that will completely resist privet invasion. Spray to wet the entire surface of the stump. Mix the herbicide with water, preparing a 3 to 5 percent solution (4 to 6 fluid ounces of herbicide product per gallon). Privet control often seems insurmountable because of its aggressive growth, prolific root and stump sprouting, copious seed production, and widespread seed dispersal by birds and other animals. Chinese privet, Ligustrum sinense, Prospects for Classical Biological Control in the Southeastern United States. There is also a triclopyr ester ready-to-use product with no mixing required. Most methods of getting rid of privet require more than one application. Several privet species occur, and distinguishing among them can be difficult. This means looking for and killing regrowth or new seedlings. Herbicides are effective, and foliar applications in early spring or late autumn (when native plants are usually dormant) are most effective. However, avoid formulations with lower concentrations as they do not contain enough glyphosate or triclopyr amine to be effective. Figure 3. Jimmy Stiles, a PhD candidate at the Auburn University School of Forestry and Wildlife Sciences, has been designing and evaluating a new program to use weed torches … Control Options for Chinese Privet (Apr 2013) Alabama Cooperative Extension System. If the label recommends additional surfactant, add a nonionic surfactant at 0.5 percent (0.6 fluid ounces per gallon). Privet can be effectively controlled with foliar, cut stump, and basal bark herbicide treatments. Brush mulching can be used anytime but may spread privet seed if used in the fall. This late fall timing is very advantageous as most other vegetation is dormant and will not be harmed by glyphosate. Chinese privet is very thin barked and even large diameter shrubs can be controlled with the basal bark treatment method. Whether these effects extend above the shrub layer into the canopy remains unclear. Brush mulchers (Figure 3) are typically mounted on skid steers and grind or mulch entire shrubs and small trees. Privet control often seems insurmountable because of its aggressive growth, prolific root and stump sprouting, copious seed production, and widespread seed dispersal by birds and other animals. A blue spray indicator or dye improves spray visibility for the applicator. By: Becca Badgett, Co-author of How to Grow an EMERGENCY Garden. For best results, cut privet stems close to the ground and remove any sawdust from the stump. Brush mulching cannot be effectively integrated with cut stump treatment because stumps will be buried under the mulch layer. Plant: Chinese privet (Ligustrum sinense) and European privet (L. vulgare) are essentially indistinguishable due to hybridization. The optimal timing for glyphosate treatment is late fall to early winter (November through early January) when day temperatures are mild. You do not need Chinese privet in your garden. Chinese privet was introduced ar Mix the herbicide with an oil carrier such as diesel or bark oil, preparing a 20 percent solution (26 fluid ounces of herbicide product per gallon). Even a twig or leaf can reproduce. Everyone is welcome! Good spray coverage over the entire plant is very important as privet shrubs sprayed only on the sides will not be completely killed. Mix the herbicide with an oil carrier such as diesel or bark oil, preparing a 20 percent solution (26 fluid ounces of herbicide product per gallon). A team of scientists investigated a popular "cut and … Foliar sprays of glyphosate and triclopyr were tested in three factorial experiments that included wide ranges of application rate, timing, and formulation to refine methods for controlling Chinese privet. Sign up to get all the latest gardening tips! If the plant does not come up easily, it is likely a sprout from a lateral root and hand pulling will not be effective.

Long used as a hedge in many parts of the southeast, the plant was found to escape cultivation readily. Glyphosate products not labeled for use in or near water often contain a surfactant that is very harmful to many aquatic organisms. Figure 6. There will almost always be a flush of new seedlings in the year following intensive control, especially along woodland edges. Chinese or hedge privet, Ligustrum sinense (Oleaceae), is a semi deciduous shrub or small tree of … For many situations, herbicides with the active ingredient glyphosate are the most effective option. Ligustrum sinense is now found in all 3 physiographic Chop existing bushes in spring. Several species of privet have been introduced in the United States since the 1700s as garden plants and hedges. Within a few weeks of cutting, use a triclopyr ester herbicide product mixed with oil instead of water. When referring to individual species, the common names listed above are used. Find more gardening information on Gardening Know How: Keep up to date with all that's happening in and around the garden. That is why I urge you to kill it wherever you find it. Thorough wetting is necessary for good control; spray until run-off is noticeable at the ground line. Sign up for our newsletter. Chinese privet, Ligustrum sinense, was originally brought to the U.S. from China for use in ornamental garden plantings. Download a PDF of Control Options for Chinese Privet, ANR – 1468. Collect and bag any fruit if possible. f.), Japanese privet (L. japonicum Thunb. Native plants are particularly important to wildlife, as they provide food and shelter for them and support beneficial insects, pollinators, and birds. These plants adapt to extremes of heat and cold while performing important functions in the ecosystem. Chinese privet, Ligustrum sinense , Prospects for Classical Biological Control in the Southeastern United States Use a triclopyr ester herbicide product. Remove the plant and spray root system. Chinese privet (Ligustrum sinense Lour. Fall is generally the best time for this treatment but it may be used any time of the year. ), and Chinese privet (L. sinense Lour.)..). Privet foliar herbicide treatments can be applied with several types of sprayers, but single nozzle backpack sprayers are used in many situations (Figure 5). Invasive ornamentals can edge out native plants with their aggressive growth and multiplication. Cutting, when used alone, does not provide satisfactory control because of rapid stump sprouting. This is evident when stumps appear to “bleed” water following cutting. Hand pulling is an option that can be used only to remove privet seedlings and small saplings. We do not need Chinese privet in this country. These recommendations for widely available privet control options can be used across a range of land management scenarios. However, do not treat during extended cold weather when temperatures are at or below freezing. Since seeds remain on the plant for several months, care must be exercised to prevent … Recommended control procedures: Thoroughly wet all leaves with one of the following herbicides in water with a surfactant (August to December): a glyphosate herbicide as a 3-percent solution (12 ounces per 3-gallon mix) or Arsenal AC* as a 1-percent solution (4 ounces per 3-gallon mix). Chinese privet (Ligustrum sinense) and other invasive privets in the genus Ligustrum are a serious problem for many homeowners, farmers, foresters, and land managers in Alabama. Because of these characteristics, the major impact of Chinese privet is its ability to displace native species and disrupt various terrestrial ecosystems. Remove all stems, including the suckers. Research plants before adding them and try to avoid those that are invasive. Cut stump treatments can be done almost any time of year but late fall is the easiest from an operational standpoint. It has been widely planted for hedges and has since escaped cultivation spreading throughout the Southeast and Midwest. There is also a triclopyr ester ready-to-use product with no mixing required. Chinese privet shown in all images. Plants form dense thickets, invading fields, fencerows, roadsides, forest understories, and riparian sites. When privet is invasive species, the cost of controlling and removing privet is economically detrimental, something that is problematic for conservation efforts. Chinese privet is a restricted invasive plant under the Biosecurity Act 2014.; It must not be given away, sold, or released into the environment without a permit. The way to do this is to cut off the trunks an inch or so above the soil during the growing season and then immediately paint the remaining cut surfaces with Roundup or Brush Killer. These seedlings and sprouts can be easily controlled with foliar glyphosate treatment, which is best done in the late fall. Additionally, when spraying along streams, ponds, and lakes, use a glyphosate product and nonionic surfactant labeled for use in aquatic environments. Spray the foliage to wet, but not to the point of runoff. Some sprouting from lateral roots and stumps missed during initial treatment will also be inevitable.
Ligustrum sinense (Chinese privet) is a very common invasive non-native shrub in the region. Weed wrenches are steel, handheld tools that grasp woody stems at the base and use leverage to lift the plant out of the ground (Figure 2). You can take these steps to rid your landscape of other invasive ornamentals too. Although cattle will readily graze some other invasive plants such as kudzu and Chinese privet, they do not graze Chinese tallowtree at all. Privet control is challenging because of its aggressive growth, prolific root and stump sprouting, abundant seed production, and widespread seed dispersal by birds and other animals. Then, within a few minutes at most, spray or paint the entire cut surface with the herbicide solution (Figure 6). Figure 7. Native plant species are quickly suppressed in the dense thickets that often form when Chinese privet grows unchecked. There are herbicide concentrate products available with lower concentrations of glyphosate (20 percent) or triclopyr amine (8 percent). If a thicket is present, cut all stems back to the ground with a chainsaw or weed-eater with a brush blade attachment. Grasp privet stems by the base and pull upward, removing as much of the root system as possible. There are several ways to do this, according to information from experts on this subject. Mow shoots that persist after plant is removed. Goats will graze Chinese tallowtree, but they do not prefer it. Ligustrum sinense can tolerate a wide range of conditions. If possible, removal should occur before seeds are produced. The annual cost of removing Chinese privet in the United States is estimated to be $737 per acre when a mulching machine and two-person herbicide application crew are employed. Identification: Thicket-forming shrubs reaching 30 feet tall are semi-evergreen with soft, woody stems and long, leafy branches.Shrubs have opposite or whorled branching that increases upward, with shorter twigs that are long and slender and projecting outward … Do you accept? However, not all glyphosate products are created equal. Let’s look at some of these controls which are most easily practiced by the homeowner. © 2020 by the Alabama Cooperative Extension System. Using a combination of control methods is usually more successful. They work best for single-stemmed plants but can also be used for some multistemmed clumps. Allow the cut stems to re-sprout, then spray the ground level foliage with a 5% solution of glyphosate with surfactant. It can be done any time of year but is easiest when soils are moist. Untreated cut stems will sprout. However, brush mulching often results in very uniform privet regrowth that can easily be sprayed. Cut and Paint Treatment Apply this treatment during the fall. All rights reserved. While this treatment can be effective … Mix the herbicide with water, preparing a 25 percent solution (32 fluid ounces of herbicide product per gallon). The invasion penetrated about 30 m under the canopy trees, providing 100% cover of the forest floor. Triclopyr ester does have some soil activity, and damage to nontarget species can occur when numerous privet stems are treated in a small area. Biological Control. Randall & Marinelli (1996) report effective control of Chinese privet with glyphosate herbicides stating that foliage treatment is best for actively growing plants. Be very careful where spray drift can damage or kill nearby desirable vegetation. Always read and follow the herbicide label, paying attention to site and rate restrictions and safety recommendations for applicators. Spray to wet, but do not puddle the herbicide around the stump. They do not remove the root system and sprouting will inevitably occur (Figure 4). Over a period of 20 years, Chinese privet, Ligustrum sinense, invaded a mixed hardwood forest in western North Carolina, USA. The weed wrench uses leverage to easily lift privet saplings out of the ground. Chinese privet will colonize by abundant bird- and other animal-dispersed seeds, after which it can spread vegetatively by vigorous root sprouting. Trade and brand names used in this publication are given for information purposes only. Because privet has a shallow fibrous root system, pulling may severely disturb the soil and is not recommended along stream banks or steeply sloped areas where erosion may be of concern. Following mulching or other mechanical treatments, privet rapidly sprouts from stumps and lateral roots. Foliar spray methods should be used only where risk to non-target species is minimal. Spray to wet, getting complete coverage of each woody stem, but do not puddle the herbicide on the soil. Follow-up monitoring and spot treatment of newly established plants should be done to prevent reinfestation. Ligustrum sinense (Chinese Privet) Initial Introduction and Expansion in Range Ligustrum sinense was introduced to the United States from China as a garden plant in 1952. This exotic shrub is notorious for producing dense thickets, especially in bottomland forests and in floodplains, where these thickets choke out all native plants. Privet can be controlled with foliar, cut stump and basal bark applications of herbi- cides. Mark Zeller, is a biologist in the Bureau of Invasive Plant Management, Florida Department of Environmental Protection, 3917 Commonwealth Boulevard, M. S. 710, Tallahassee, Florida 32399-3000. These non-native shrubs, which are difficult to distinguish from one another, include: common privet (L. vulgare L.), glossy privet (L. lucidum Ait. Spray the entire surface and sides of the stump. Use an herbicide concentrate product with either 41 percent or higher active ingredient glyphosate or 44 percent active ingredient triclopyr amine. For more information, contact your county Extension office. Varying degrees of control have been achieved using glyphosate, imazapyr, triclopyr, metsulfuron, and hexazinone. There are several ways to do this, according to information from experts on this subject. They can vary in concentration and may or may not include a surfactant, which improves absorption into the leaves. Getting rid of Chinese privet that’s popped up throughout your landscape is a good place to begin Chinese privet control. Weed wrenches are effective for removing privet saplings up to 2 inches in diameter. Chinese privet is one of the most widely spread invasive plants in the South. Don’t purchase or plant Chinese Privet in the landscape. Visit www.aces.edu/directory. ), is known to negatively affect biodiversity near the ground in invaded forests by forming thick layers of non-native vegetation in the midstory. Successful weed control requires follow up after the initial efforts. No guarantee, endorsement, or discrimination among comparable products is intended or implied by the Alabama Cooperative Extension System. Two studies, a multisite field investigation and a controlled approach on a single site, were conducted to examine the role of Chinese privet (Ligustrum sinense) on decomposition within riparian forests of the Georgia Piedmont. Managing Chinese Privet Getting rid of Chinese privet that’s popped up throughout your landscape is a good place to begin Chinese privet control. When applying glyphosate, volatility and soil activity are not a concern. Over time, Chinese privet weeds began springing up in forests and other areas where it has overtaken native plants and become established. If the herbicide treatment must be delayed following cutting, a different approach must be used. Skid steer mulchers can quickly grind dense stands of privet to the ground. The Alabama Cooperative Extension System (Alabama A&M University and Auburn University) is an equal opportunity educator and employer. Please review our Privacy Statement for more information. Figure 5. Therefore, many states have programs dedicated solely to the maintenance and removal of invasive plants like Chinese privet. Most brush mulchers can mulch all sizes of privet and often leave a thick mulch layer. Featured Image by Karan A. Rawlins, University of Georgia, Bugwood.org. http://southernforesthealth.net/plants/chinese-privet. Once established, it is exceedingly difficult to control. Privet often escapes into pastureland, where it shades out grass and other grazing crops. Apply a foliar spray with 41 percent glyphosate or triclopyr mixed with oil, allow ten days. is an ideal shrub for hedges and decorative topiary because it grows aggressively whether planted in sun or partial shade. Once established, Chinese privet is difficult to control because of the huge seedbank and the need to remove underground parts as well. Use a concentrate type product with at least 41 percent glyphosate. Cutting Back Privet: How And When To Prune Privet Hedges, Ligustrum Care: Information On How To Grow Ligustrum Shrubs, Is Glyphosate Dangerous?
