In 1953, kudzu was removed from the US Department of Agriculture’s list of permissible cover plants due to its recognition as a pest species. 1). Benth, and P. hirsuta (Thunb.) Estimates of the vine's spread vary, from the United States Forest Service's 2015 estimate of 2,500 acres per year to Bulletin of the Torrey     Botanical Club 116: 390-394. To control kudzu by grazing it is necessary to adequately fence the entire patch and to … Seed pods are often empty, but may contain 10 to 12 seeds per pod (Tabor, 1942). in North Carolina. Alabama     Cooperative Extension Service Circular ANR-65, Auburn University, Auburn, Alabama, USA. Only killing or removing the kudzu root crownand all rooting runners is needed. Kudzu’s nearest relative in the United States is the soybean, Glycine max (L.) Merr., which also is of Asian origin. Leaves have three leaflets with variable lobes. The vines grow up to 18m/yr in Georgia (Weschler, 1977). Kudzu seedling nurseries produced and distributed more than 73 million seedlings between 1935 and 1941 (Tabor and Susott, 1941). Pseudomonas syringae pv. Two years of testing in Mississippi demonstrated that the fungus attacks leaves and stems, with greater activity at 25 to 40°C than at 10 to 20°C. “Losses vary with the potential use of the land in an uninfested state. The vines grow up and over almost any structure, including houses, and conceal from view entire buildings in unmonitored locations.

Kudzu control on forest planting sites. are lobed leaflets, and the size of wing and keel petals, all of which can be quite variable. Alabama Agricultural     Experiment Station Circular 83, Auburn, Alabama. Thus, kudzu control for forest production is not economically feasible.” Dr. James Miller (USDA Forest Service plant ecologist, Auburn, Alabama), who has researched herbicides for kudzu control for the last 20 years, estimates control costs by power companies alone at $1.5 million per year. and Sacc. Appearance. 2nd ed. Kudzu leaves have 3 egg-shaped leaflets attached to a long leaf stalk. The condition of the state's soil, already depleted by poor agricultural practices, worsened. Distribution of Pueraria lobata in and around New York City. An exclusion cage study conducted in 1998 and 1999 revealed that low levels of kudzu seed viability were the result of arthropod damage. They are quite tasty stir-fried! [  Next  ], Warnell School of Forestry and Natural Resources, College of Agricultural and Environmental Sciences. For a middle school science fair project, he wanted to use kudzu to terraform the Red Planet and make it livable. Sun, and K. O. Britton. Characteristics that had been used previously to differentiate P. montana from P. lobata and Pueraria thomsoni (Benth.) It does not strangle competition, but simply blankets trees with a dense canopy, through which little light can penetrate. Seed production by kudzu in the United States varies from 0 to 1,800 seeds per m2 soil surface, with higher values occurring where vines are climbing on structures (Thornton, 2001). Its vines can grow to a diameter of up to 1+ inches here in Georgia. Field tests demonstrated that 95 to 100% control could be achieved within 14 days of inoculation by girdling runner stems with this fungus, which produces asexual spores in a sporodochium, with a matrix suggesting dispersal by splashing rain. The most severe infestations occur in the piedmont regions of Mississippi, Alabama, and Georgia. Maesen’s (1985) extensive examination of herbarium specimens led him to conclude that the kudzu in Japan, Korea, China north of Shanghai, and throughout the Phillipines, Malaysia, and Indonesia, was P. montana var. UGA Extension and the College of Agricultural and Environmental Sciences are working to combat this problem from all angles. Maesen and Almeida (Ward, 1998). Field inoculations showed a synergistic effect was achieved by inoculations of spores together with 20% of the recommended rate of dicamba.

This pathogen has been reported on several Pueraria species from Japan, New Guinea, Java, the Phillipines, India, China, and California (specimen at National Fungus Collection, Beltsville, Marlyand (Karling, 1964), but further investigations are necessary to confirm its host specificity. The distribution of P. montana var. Few plants can survive once smothered by kudzu. Insect feeding, mating, and egg laying behavior was observed at 10-day intervals from May through November. Please contact us with any questions or concerns you may have . However, it proved difficult to bale. 1997. Ohwi, P. thunbergiana (Sieb. 1941. (Maesen, 1985). Ornamental use accounts for the predominance of kudzu around many old, collapsed southern homesteads (Fig. In 2001, a wider range of plants common to the United States and China will be tested in China, and a host test list will be submitted to the Technical Advisory Group before United States quarantine tests are planned. You'll want to get the support and guidance of your local kudzu control program authority; even simple mowing and grazing methods require that you contain the infested area by cutting large vines and fencing it off. Contact Us. Maesen and Almeida) was originally introduced into the United States as an ornamental vine at the Philadelphia Centennial Exposition of 1876. The extremely low viability of these seeds has been assumed to be due to a lack of pollinators. January 16-19, 2001. The leaves can grow up to 6 inches long and are covered in tiny hairs, which give it a fuzzy appearance. Kudzu vines can hide logs, stumps, ditches, and anything abandoned in the area making mowing hazardous. Kudzu rarely occurs in the northeastern United States (Frankel, 1989), but is occasionally found from Connecticut to Illinois. lobata was not known to have established in Africa. Step 1… Feeding by a naturalized Asian bruchid (Borowiecius ademptus Sharp) resulted in a small amount of damage in both years (Thornton, 2001). W. S.

Seedlings develop a woody root crown, with multiple runners and extensive tuberous roots. The siege of invasive species in Midwest ecosystems, pp. A patent for kudzu control has been applied for. Castanea 61: 313-319. A strain of this widely-distributed pathogen was isolated from kudzu in Houston County, Georgia, and its virulence was increased by repeated selection for growth on Czapek Dox medium amended with kudzu extract. In inoculation studies, a surfactant was needed for good infection (Boyette, 2000). Flowers of Pueraria montana. 1995. Sturkie, D. G., and J. C. Grimes. In his 1949 book, Front Porch Farmer, Channing Cope presents kudzu as the panacea that will allow farmers to adopt a life of leisure and relaxation, as this new crop “works while you sleep.” Kudzu was widely promoted as a drought-resistant, high-nitrogen forage crop. From herbicide resistant pigweed to Asiatic soybean rust, boll weevils to kudzu, invasive species are a prevalent and persistent problem in Georgia.

However, Thornton demonstrated that there are a variety of both native and naturalized pollinators, the most important of which are native Hymenoptera. The older the crowns, the deeper they tend to be found in the ground. Revegetation of sites following treatment is an important last step to ensure that any residual kudzu does not reestablish. Pemberton (1988) reported an abundance of natural enemies of kudzu in China and Korea. Georgia Forestry     Commission Conservation Reserve Program Note 15. phaseolicola. Van der Maesen (1985) considered China, Indo-China, Japan, Malaysia, Oceania, and the Indian subcontinent the native range of the genus Pueraria.
