Introduction North Avenue, Geneva, NY 14456. (Email: [email protected]) Field bindweed (Convolvulus arvensis L.) is a perennial vine in the Convolvulaceae, or morning- glory family, which includes approximately 50 to 60 genera and more than 1,500 species (Preston 2012a; Stefanovic et al. 2003). The family is in the order Solanales and is characterized by alternate leaves (when present) and bisexual flowers that are 5-lobed, folded/pleated in the bud, and trumpet-shaped when emerged (Preston 2012a; Stefanovic et al. -

Owing to the superior quality of their grapes, these cultivars were long considered the only suitable for the production of high quality wines. However, the lack of resistance genes to fungal diseases like powdery and downy mildew (Uncinula necator and Plasmopara viticola) makes it necessary the application of huge amounts of chemical products in vineyard. Thus, the search for alternative and more sustainable methods to control the major grapevine pathogens have increased the interest in new disease tolerant varieties. Chemical characterisation of these varieties is an important prerequisite to evaluate and promote their use on the global wine market. The aim of this project was to produce a comprehensive study of some promising new disease tolerant varieties recently introduced to the cultivation by identifying the peculiar aspects of their composition and measuring their positive and negative quality traits. -

NF585 Bindweed Identification and Control Options for Organic Production By Laurie Hodges, Extension Vegetable Specialist Two species of bindweed are commonly found in the small and green. Each plant can produce 11,000-30,000 Great Plains and one unrelated weed is often confused with seeds between June and September. Although most of the bindweed. Field bindweed (Convolvulus arvensis) is also viable seed will germinate the following year, seeds can known as small morning glory. It has smooth, slender remain viable for about five years. This plant is a strong stems two to seven feet long that twine or spread over the climber and can compete for light in dense crop stands. It soil surface. The leaves are shaped like arrowheads. The can spread rapidly and is highly competitive for moisture white or pale pink flowers are about one inch across. -
Assembled by Mark Frey with Help from Many Volunteers 1/9/2015 DRAFT 1. No Apparent Leaves
Vine key for the National Capital Region This key includes vine and vine-like plants found in the National Capital Region. Much of the information was drawn from Gleason and Cronquist (1991) and Weakley (2013). Vines and vine-like plants are defined here as species you might, at least occasionally, encounter growing above your knee and requiring the support of another plant or structure to grow that high. Brambles (Rubus spp.) are not included because they don't act as vines and multiflora rosa (Rosa multiflora ) is included because it does occaisionally act as a vine. Plants found only under cultivation are not included. Assembled by Mark Frey with help from many volunteers 1/9/2015 DRAFT 1.

Kentucky Unwanted Plants
Chapter 6 A Brief Guide to Kentucky’s Non-Native, Invasive Species, Common Weeds, and Other Unwanted Plants A publication of the Louisville Water Company Wellhead Protection Plan, Phase III Source Reduction Grant # X9-96479407-0 Chapter 6 A Brief Guide to Kentucky’s Non-native, Invasive Species, Common Weeds and Other Unwanted Plants What is an invasive exotic plant? A plant is considered exotic, (alien, foreign, non- indigenous, non-native), when it has been introduced by humans to a location outside its native or natural range. Most invasive, exotic plants have escaped cultivation or have spread from its origin and have become a problem or a potential problem in natural biological communities. For example, black locust, a tree that is native to the southern Appalachian region and portions of Indiana, Illinois, and Missouri, was planted throughout the U.S. for living fences, erosion control, and other uses for many years. Black locust is considered exotic outside its natural native range because it got to these places Kudzu is an invasive exotic plant that has spread by human introduction rather than by natural from Japan and China to become a large problem in dispersion. It has become invasive, displacing native much of the US. Local, state, and the federal species and adversely impacting ecosystems and governments spend millions of dollars per year to several endangered native bird species that depend on control the spread of kudzu. Even yearly control other plants for food, as well as several endangered may not be enough to successfully remove kudzu. Seeds can remain dormant in the plant species.
