Réad the following scientific method. g passage and determine the parts of the Kudzu was introduced with late 1800s. The invasive weed intentions first good intentions into the southeastern United States in the ivestock, ndfd was first planted as a home omamental, then as a forage as a way to control soil erosion. What we didnt know back then is that this native Asian plant instead, it hides erosion while quickly gobbling up surrounding landscapes. Kudzu of leaves. damages or kills other plants by smothering them under layers es stiil form underneath kudzu, You just cant see them says plant pathologist evidence of large-scale, Mark A. Weaver, at the Agricultural Research Services (ARS) Biological Control of Pests Research Unit in Stoneville, Mississippi. These gullies are uncontrolled soil erosion. Weaver and his colleagues are looking for quicker and more effective ways to control kudzu, which typically takes about 10 years of persistent herbicide applications to eradicate. Recently, they developed effective management programs, including one that uses an ARS-developed bioherbicide, mowing, and revegetation. We didnt just kill the kudzu and leave the solil open for erosion Weaver says. At the same time, we achieved a good establishment of a desirable native vegetation. In this case, we planted switchgrass Land infested with kudzu has no value, Weaver says. The plant disrupts native ecosystems, threatens natural resources, and inhibits use of forest land, particularly in Mississippi, where kudzu is pervasive. The faster you can get rid of kudzu, the faster you can start doing something positive with the land-establishing forestry, wildlife habitat, or recreational land. Weaver says. We wanted to know if we could achieve an even higher rate of kudzu suppression and possibly eradicate it by combining successful control programs In his study, Weaver created research plots at three different infested sites. He repeated a series of treatment programs for 2 years. He tested the effectiveness of four different commercially available herbicides, either individually or in combination, and a bioherbicide treatment We achieved a high level of suppression quickly and effectively on these mini plots after just 1 year, Weaver says. In the second year, an even higher percentage of kudzu was killed using the herbicides, which are tolerated by some crops and are compatible with livestock grazing. Results of the integrated herbicide programs were excellent: 99- to 100-percent reduction in kudzu, Weaver says.
