Thus, both in terms of quantities produced and the value of its products, the vine constitutes a particularly important cultivation. THE HOST PLANT AND ITS CULTIVATION The original area of distribution of the genus Vitis was broken up by the separation of the continents; although numerous species developed, Vitis vinifera has been cultivated from the beginning for its fruit and wine producing qualities (43, 75, 184). This cultivation commenced in Transcaucasia about 6000 B.C. Subsequent human migration spread its cultivation, at firstaround the Mediterranean coast; the Roman conquest led to the plant's progressive establishment in Europe, almost to its present extent. Much later, the WesternEuropeans planted the grape vine wherever cultiva­ tion was possible, i.e. throughout the temperate and warm temperate regions of the by NORTH CAROLINA STATE UNIVERSITY on 02/01/10.

It outlines the mission-related goals, objectives, and anticipated accomplishments as well as the approach for conducting a Grape Commodity survey and control program and the related roles and responsibilities of the Kansas Department of Agriculture and USDA-APHIS-PPQ as negotiated. I) OBJECTIVES AND NEED FOR ASSISTANCE In 1985, Kansas passed the Farm Winery Act establishing guidelines for wineries and by 2005, 13 licensed farm wineries in Kansas produced 50,000 gallons of wine from only 170 total acres of grapes. In January 2010, the number of licensed farm wineries had grown to 23 located in 21 counties from central to northeastern Kansas. In 2010, the total number of acres of grapes in Kansas vineyards was 342.1 acres on 73 farms and this continues to grow. There were 174.1 acres of grapes harvested with 354.7 tons of grapes produced. Over 60 percent of grapes produced are used at their own operations. The total value in 2010 of grapes produced was $401,150 and this continues to rise.

  • 2017 Grape Survey Report
    2017 Grape Survey K. Buckley & M. Klaus 2017 Entomology Project Report - Plant Protection Division, Pest Program Washington State Department of Agriculture 2 May 2018 2017 Grape Survey Report Katharine D. Buckley & Michael W. Klaus, Washington State Department of Agriculture Summary The WSDA conducted a Grape Commodity Survey in 2017 to determine the status of invasive pests and diseases in Washington State affecting juice, wine and table grapes. Except for Grape Phylloxera, which is known to occur in Washington, no other target pests of this survey were found. Background Washington State is 2nd in the US in wine grape production with 55,445 acres currently in production (Mertz et al. 2017), which support over 900 wineries (washingtonwine.org). The impact of this wine industry on the state is estimated to be $4.8 billion (washingtonwine.org). Washington is also the largest producer of juice grapes (Honig et al. 2017) with 21,632 acres of primarily Concord and some Niagara varieties (Mertz et al. 2017). The value of these crops could decrease substantially if certain invasive pests established here. Additional pesticide sprays would be required, which would disrupt Integrated Pest Management (IPM) programs already in place. All of these pests and diseases are also restricted by various countries, making exports of vine stock, nursery stock and fresh fruit more difficult. 1 2017 Grape Survey K. Buckley & M. Klaus Light Brown Apple Moth (Epiphyas postvittana (Walker)) Light brown apple moth (LBAM) is a highly polyphagous species with more than 1,000 plant species including over 250 fruits and vegetables such as apples, citrus, corn, peaches, berries, tomatoes and avocados (Weeks et al.

Received: 30 March 2020; Accepted: 4 May 2020; Published: 7 May 2020 Abstract: Ochratoxin A (OTA) is the most toxic member of ochratoxins, a group of toxic secondary metabolites produced by fungi. The most relevant species involved in OTA production in grapes is Aspergillus carbonarius. Berry infection by A. carbonarius is enhanced by damage to the skin caused by abiotic and biotic factors. Insect pests play a major role in European vineyards, and Lepidopteran species such as the European grapevine moth Lobesia botrana are undoubtedly crucial. New scenarios are also emerging due to the introduction and spread of allochthonous pests as well as climate change. Such pests may be involved in the dissemination of OTA producing fungi even if confirmation is still lacking and further studies are needed.

  • European Grape Berry Moth Eupoecilia Ambiguella Juliet Carroll and Nicole Mattoon, New York State Integrated Pest Management Program, Cornell University
    hdl.handle.net/1813/44259 NEW YORK STATE Invasive Species Integrated Pest Management PROGRAM & Exotic Pests European Grape Berry Moth Eupoecilia ambiguella Juliet Carroll and Nicole Mattoon, New York State Integrated Pest Management Program, Cornell University European grape berry moth is native to Europe and Central Asia. It primarily feeds on grapes (Vitis vinifera) but has also been found in honeysuckle and currant berries. While European grape berry moth has yet to be discovered in the United States, its arrival could negatively impact the grape industry because it is a direct pest feeding on berries. Concern Grapes are used in a variety of production industries, and the introduction of European grape berry moth could greatly affect wine, juice, and table grape industries. The larvae may also feed on various other horticultural and native plants. European grape berry moth prefers Northern, humid climates making it of particular concern to the grape growing regions of New York, as well as the Great Lakes European grape berry moth adult. Photo: Todd and Northeast. In Northern Europe and Southern Germany this moth Gilligan, Screening Aids, USDA APHIS ITP, can cause severe damage in wine production areas. Bugwood.org. Description Adult European grape berry moths have forewings that are about ¼ inch long, yellowish brown with a dark brown band down the middle. Females are slightly larger than males. These moths have two generations per year and can be seen between May and June (1st generation) and between August and September (2nd generation). The first generation of eggs can be found on buds, pedicels, and flowers while the second generation of eggs can be found on grape berries.

The total area under vines is about 189.7 thousands ha, being an intensive culture, the area of grapevine has 2% of the agricultural area and income from viticulture is 10% from the value of the agriculture production. It is analyzes the situation of the main pests from grapevine plantations of Romania in the light of problems related to the emergence of new or modifications of the importance of harmful pests. European regulations are the main pest management of vine plantations, as well as national regulations it is analysed. Given the increasing use of pesticides is emphasized as a comparison of European and national legislation on the approval of pesticides used in plantations of vines, is also comparing the European and national legislation on the marketing and use of pesticides in plantations vines. The impact of exotic pests varies considerably depending on the species and the area being invaded. Some species are able to rapidly colonize an area and become serious pests, often because they are no longer under control of predators or diseases that limited their numbers in their native habitat.
