Ligustrum sinense (Chinese privet) is a very common invasive non-native shrub in the region. Always read and follow the herbicide label, paying attention to site and rate restrictions and safety recommendations for applicators. Grasp privet stems by the base and pull upward, removing as much of the root system as possible. Invasive ornamentals can edge out native plants with their aggressive growth and multiplication. The Alabama Cooperative Extension System (Alabama A&M University and Auburn University) is an equal opportunity educator and employer. Ideally, you can burn it. Over a period of 20 years, Chinese privet, Ligustrum sinense, invaded a mixed hardwood forest in western North Carolina, USA. That is why I urge you to kill it wherever you find it. Don’t purchase or plant Chinese Privet in the landscape. Glyphosate products not labeled for use in or near water often contain a surfactant that is very harmful to many aquatic organisms. Additionally, when spraying along streams, ponds, and lakes, use a glyphosate product and nonionic surfactant labeled for use in aquatic environments. When referring to individual species, the common names listed above are used. Privet can be controlled with foliar, cut stump and basal bark applications of herbi- cides. Mix the herbicide with water, preparing a 25 percent solution (32 fluid ounces of herbicide product per gallon). Remove the plant and spray root system. ), is known to negatively affect biodiversity near the ground in invaded forests by forming thick layers of non-native vegetation in the midstory. This means looking for and killing regrowth or new seedlings. Privet can be effectively controlled with foliar, cut stump, and basal bark herbicide treatments. A spray indicator helps keep track of what has been treated. Varying degrees of control have been achieved using glyphosate, imazapyr, triclopyr, metsulfuron, and hexazinone. 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. Glyphosate treatments applied in the spring and summer may not provide effective control and the risk of damage to surrounding vegetation is much greater. This exotic shrub is notorious for producing dense thickets, especially in bottomland forests and in floodplains, where these thickets choke out all native plants.

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. If the privet is taller than 6 to 8 feet, consider using other methods such as brush mulching, basal bark, or cut stump treatment. Several privet species occur, and distinguishing among them can be difficult. We do not need Chinese privet in this country. Untreated cut stems will sprout. When privet is invasive species, the cost of controlling and removing privet is economically detrimental, something that is problematic for conservation efforts. Long used as a hedge in many parts of the southeast, the plant was found to escape cultivation readily. 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. Ligustrum sinense can tolerate a wide range of conditions. No guarantee, endorsement, or discrimination among comparable products is intended or implied by the Alabama Cooperative Extension System. 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.

This method entails spraying the entire circumference of the bottom 12 to 15 inches of each stem with an oil soluble herbicide (Figure 7). Ligustrum sinense is now found in all 3 physiographic and economic well-being. Let’s look at some of these controls which are most easily practiced by the homeowner. Chinese privet, Ligustrum sinense, Prospects for Classical Biological Control in the Southeastern United States. Following privet control, many factors influence which species naturally recolonize the site. Hand pulling is an option that can be used only to remove privet seedlings and small saplings. If the label recommends additional surfactant, add a nonionic surfactant at 0.5 percent (0.6 fluid ounces per gallon). Research plants before adding them and try to avoid those that are invasive. Figure 3. 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. Apply a foliar spray with 41 percent glyphosate or triclopyr mixed with oil, allow ten days. Most brush mulchers can mulch all sizes of privet and often leave a thick mulch layer. However, it can be integrated with cut stump or foliar herbicide treatments described below. However, not all glyphosate products are created equal. They work best for single-stemmed plants but can also be used for some multistemmed clumps. Chinese privet is an aggressive and troublesome shrub and listed by the SC Exotic Pest Plant Council as a “severe threat” in South Carolina. The only time cut stump treatments should not be done is in the early spring when privet shrubs are experiencing strong upward sap flow. It can be done any time of year but is easiest when soils are moist. To tackle narrow-leaf privet: control mature trees to reduce seed production; check for new seedlings; control young plants before they produce seed For more information, contact your county Extension office. There will almost always be a flush of new seedlings in the year following intensive control, especially along woodland edges. Although cattle will readily graze some other invasive plants such as kudzu and Chinese privet, they do not graze Chinese tallowtree at all. Good spray coverage over the entire plant is very important as privet shrubs sprayed only on the sides will not be completely killed. Privet (Ligustrum spp.) The invasion penetrated about 30 m under the canopy trees, providing 100% cover of the forest floor. Sign up to get all the latest gardening tips! The first step in preventative control of privet is the removal of existing plants within the landscape and to limit planting. Collect and bag any fruit if possible. 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). Privet often escapes into pastureland, where it shades out grass and other grazing crops. Both water- and oil-based cut stump treatments work on any size privet, but it is critical to treat every cut stem. Triclopyr ester does have some soil activity, and damage to nontarget species can occur when numerous privet stems are treated in a small area. Cutting Back Privet: How And When To Prune Privet Hedges, Ligustrum Care: Information On How To Grow Ligustrum Shrubs, Is Glyphosate Dangerous? Herbicides are effective, and foliar applications in early spring or late autumn (when native plants are usually dormant) are most effective. This late fall timing is very advantageous as most other vegetation is dormant and will not be harmed by glyphosate. 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. Use an herbicide concentrate product with either 41 percent or higher active ingredient glyphosate or 44 percent active ingredient triclopyr amine. Drift, however, can be a serious problem, especially on windy days. Native plant species are quickly suppressed in the dense thickets that often form when Chinese privet grows unchecked. Once established, it is exceedingly difficult to control. However, avoid formulations with lower concentrations as they do not contain enough glyphosate or triclopyr amine to be effective. These are applied to stumps at full strength. A 2% solution of glyphosate or … This method entails cutting followed by application of an herbicide to the surface of the stump. There are several ways to do this, according to information from experts on this subject. 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). There are several ways to do this, according to information from experts on this subject. © 2020 by the Alabama Cooperative Extension System. Brush mulching cannot be effectively integrated with cut stump treatment because stumps will be buried under the mulch layer. Thorough wetting is necessary for good control; spray until run-off is noticeable at the ground line. Researchers say you can achieve great control with much less herbicide than typically used. 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. Total eradication is extremely difficult with well-established plants. is an ideal shrub for hedges and decorative topiary because it grows aggressively whether planted in sun or partial shade. 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. Chinese privet was introduced ar Use a concentrate type product with at least 41 percent glyphosate. 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. By: Becca Badgett, Co-author of How to Grow an EMERGENCY Garden. Weed wrenches are effective for removing privet saplings up to 2 inches in diameter. 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 … The Act requires everyone to take all reasonable and practical steps to minimise the risks associated with invasive plants and animals under their control. For best results, cut privet stems close to the ground and remove any sawdust from the stump. Even a twig or leaf can reproduce. Spray to wet, but do not puddle the herbicide around the stump. In addition to sunlight and moisture availability, these factors include surrounding vegetation and prior land use. They do not remove the root system and sprouting will inevitably occur (Figure 4). Trade and brand names used in this publication are given for information purposes only. Therefore, many states have programs dedicated solely to the maintenance and removal of invasive plants like Chinese privet. 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). While privet seeds in the soil seed bank only survive for about one year, birds and flooding can reintroduce seed into the area. To direct this process of recolonization and site restoration, land managers may choose to actively plant desired species. This treatment may take a few months to kill privet but it is very effective. However, do not treat during extended cold weather when temperatures are at or below freezing. Mow shoots that persist after plant is removed. Skid steer mulchers can quickly grind dense stands of privet to the ground. Randall & Marinelli (1996) report effective control of Chinese privet with glyphosate herbicides stating that foliage treatment is best for actively growing plants. Over time, Chinese privet weeds began springing up in forests and other areas where it has overtaken native plants and become established. Mix the herbicide with water, preparing a 3 to 5 percent solution (4 to 6 fluid ounces of herbicide product per gallon). Using a combination of control methods is usually more successful. 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. Some sprouting from lateral roots and stumps missed during initial treatment will also be inevitable. Biological Control. Whatever the method of herbicide application, landowners should be prepared for … No single treatment will eradicate privet. If possible, removal should occur before seeds are produced. Cutting, when used alone, does not provide satisfactory control because of rapid stump sprouting. Arundinaria gigantea (giant cane) is a native bamboo species that used to be very abundant in riparian and wetland ecosystems in the region. They can shade out and exclude native understory species, perhaps even reducing tree recruitment. Be very careful where spray drift can damage or kill nearby desirable vegetation. Once established, Chinese privet is difficult to control because of the huge seedbank and the need to remove underground parts as well. 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. Figure 6. Figure 4. Plant: Chinese privet (Ligustrum sinense) and European privet (L. vulgare) are essentially indistinguishable due to hybridization. They quickly remove dense stands of privet, providing immediate access to an area. Chinese or hedge privet, Ligustrum sinense (Oleaceae), is a semi deciduous shrub or small tree of … Chinese privet, Ligustrum sinense, was originally brought to the U.S. from China for use in ornamental garden plantings. They can vary in concentration and may or may not include a surfactant, which improves absorption into the leaves. Several species of privet have been introduced in the United States since the 1700s as garden plants and hedges. Then, within a few minutes at most, spray or paint the entire cut surface with the herbicide solution (Figure 6). that ensures all people have access to information that improves their quality of life For example, Chinese privet has become well established in southeastern forests and continues to spread. Getting rid of Chinese privet that’s popped up throughout your landscape is a good place to begin Chinese privet control. Dispose of it away from your landscape. Chinese privet will colonize by abundant bird- and other animal-dispersed seeds, after which it can spread vegetatively by vigorous root sprouting. If a thicket is present, cut all stems back to the ground with a chainsaw or weed-eater with a brush blade attachment. Please review our Privacy Statement for more information. There is also a triclopyr ester ready-to-use product with no mixing required. Chinese privet is one of the most widely spread invasive plants in the South. Follow-up monitoring and spot treatment of newly established plants should be done to prevent reinfestation. Successful weed control requires follow up after the initial efforts. Privet foliar herbicide treatments can be applied with several types of sprayers, but single nozzle backpack sprayers are used in many situations (Figure 5). These seedlings and sprouts can be easily controlled with foliar glyphosate treatment, which is best done in the late fall. Do not use glyphosate formulations that are called “Ready to Use” because they generally do not contain enough glyphosate to be effective. 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. Spray the entire surface and sides of the stump. If the herbicide treatment must be delayed following cutting, a different approach must be used. Spray to wet the entire surface of the stump. Chinese privet is a nonnative shrub that has invaded mesic forests throughout the southeastern United States during the past century. This is evident when stumps appear to “bleed” water following cutting. Spray to wet, getting complete coverage of each woody stem, but do not puddle the herbicide on the soil. Find more gardening information on Gardening Know How: Keep up to date with all that's happening in and around the garden. The optimal timing for glyphosate treatment is late fall to early winter (November through early January) when day temperatures are mild. Chinese privet is very thin barked and even large diameter shrubs can be controlled with the basal bark treatment method. There is also a triclopyr ester ready-to-use product with no mixing required. Within a few weeks of cutting, use a triclopyr ester herbicide product mixed with oil instead of water. Spray the foliage to wet, but not to the point of runoff. Cut stump treatments can be done almost any time of year but late fall is the easiest from an operational standpoint. These plants adapt to extremes of heat and cold while performing important functions in the ecosystem. These non-native shrubs, which are difficult to distinguish from one another, include: common privet (L. vulgare L.), glossy privet (L. lucidum Ait.

Foliar spray methods should be used only where risk to non-target species is minimal. 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. There are herbicide concentrate products available with lower concentrations of glyphosate (20 percent) or triclopyr amine (8 percent). Figure 2. Managing Chinese Privet Getting rid of Chinese privet that’s popped up throughout your landscape is a good place to begin Chinese privet control. ), and Chinese privet (L. sinense Lour.)..). 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). Control Options for Chinese Privet (Apr 2013) Alabama Cooperative Extension System. Cooperative Extension System operates as the primary outreach organization However, brush mulching often results in very uniform privet regrowth that can easily be sprayed. A blue spray indicator or dye improves spray visibility for the applicator. It has been widely planted for hedges and has since escaped cultivation spreading throughout the Southeast and Midwest. Following mulching or other mechanical treatments, privet rapidly sprouts from stumps and lateral roots. 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). Native plants are particularly important to wildlife, as they provide food and shelter for them and support beneficial insects, pollinators, and birds. Figure 7. Brush mulching can be used anytime but may spread privet seed if used in the fall. Whether these effects extend above the shrub layer into the canopy remains unclear. 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. Methods of control may be “cultural, preventative, manual, and mechanical removal, biological control, physical controls, and herbicides” or combinations of these. Brush mulchers (Figure 3) are typically mounted on skid steers and grind or mulch entire shrubs and small trees. 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. The Alabama For many situations, herbicides with the active ingredient glyphosate are the most effective option. When applying glyphosate, volatility and soil activity are not a concern. When discussing characteristics common to all 4 species, this report refers to them collectively as privet or privets. This is not, however, exhaustive as certain herbicides used in forestry and rights-of-way are not covered. Grazing is usually not an option for Chinese tallowtree control. Chinese privet shown in all images. Visit www.aces.edu/directory. 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. All rights reserved. Plants form dense thickets, invading fields, fencerows, roadsides, forest understories, and riparian sites. 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.

Allow the cut stems to re-sprout, then spray the ground level foliage with a 5% solution of glyphosate with surfactant. Most methods of getting rid of privet require more than one application. Figure 5. Chinese privet, Ligustrum sinense , Prospects for Classical Biological Control in the Southeastern United States These recommendations for widely available privet control options can be used across a range of land management scenarios. 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. Since seeds remain on the plant for several months, care must be exercised to prevent … Chinese privet (Ligustrum sinense Lour. If the plant does not come up easily, it is likely a sprout from a lateral root and hand pulling will not be effective. This creates a good setup for a late fall foliar treatment with the herbicide glyphosate. Use a triclopyr ester herbicide product. However, with the correct approach and diligent follow-up treatments, privet can be effectively controlled. f.), Japanese privet (L. japonicum Thunb. Featured Image  by Karan A. Rawlins, University of Georgia, Bugwood.org. Cooperative Extension System, Posted by: Stephen Enloe, Nancy Loewenstein. 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. Ligustrum sinense (Chinese privet) is a very common invasive non-native shrub in the region. Always read and follow the herbicide label, paying attention to site and rate restrictions and safety recommendations for applicators. Grasp privet stems by the base and pull upward, removing as much of the root system as possible. Invasive ornamentals can edge out native plants with their aggressive growth and multiplication. The Alabama Cooperative Extension System (Alabama A&M University and Auburn University) is an equal opportunity educator and employer. Ideally, you can burn it. Over a period of 20 years, Chinese privet, Ligustrum sinense, invaded a mixed hardwood forest in western North Carolina, USA. That is why I urge you to kill it wherever you find it. Don’t purchase or plant Chinese Privet in the landscape. Glyphosate products not labeled for use in or near water often contain a surfactant that is very harmful to many aquatic organisms. Additionally, when spraying along streams, ponds, and lakes, use a glyphosate product and nonionic surfactant labeled for use in aquatic environments. When referring to individual species, the common names listed above are used. Privet can be controlled with foliar, cut stump and basal bark applications of herbi- cides. Mix the herbicide with water, preparing a 25 percent solution (32 fluid ounces of herbicide product per gallon). Remove the plant and spray root system. ), is known to negatively affect biodiversity near the ground in invaded forests by forming thick layers of non-native vegetation in the midstory. This means looking for and killing regrowth or new seedlings. Privet can be effectively controlled with foliar, cut stump, and basal bark herbicide treatments. A spray indicator helps keep track of what has been treated. Varying degrees of control have been achieved using glyphosate, imazapyr, triclopyr, metsulfuron, and hexazinone. 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. Glyphosate treatments applied in the spring and summer may not provide effective control and the risk of damage to surrounding vegetation is much greater. This exotic shrub is notorious for producing dense thickets, especially in bottomland forests and in floodplains, where these thickets choke out all native plants. Download a PDF of Control Options for Chinese Privet, ANR – 1468. Sign up for our newsletter. 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. If the privet is taller than 6 to 8 feet, consider using other methods such as brush mulching, basal bark, or cut stump treatment. Several privet species occur, and distinguishing among them can be difficult. We do not need Chinese privet in this country. Untreated cut stems will sprout. When privet is invasive species, the cost of controlling and removing privet is economically detrimental, something that is problematic for conservation efforts.
