  • Disease and Insect Resistant Ornamental Plants: Viburnum
    nysipm.cornell.edu 2018 hdl.handle.net/1813/56379 Disease and Insect Resistant Ornamental Plants Mary Thurn, Elizabeth Lamb, and Brian Eshenaur New York State Integrated Pest Management Program, Cornell University VIBURNUM Viburnum pixabay.com Viburnum is a genus of about 150 species of de- ciduous, evergreen and semi-evergreen shrubs or small trees. Widely used in landscape plantings, these versatile plants offer diverse foliage, color- ful fruit and attractive flowers. Viburnums are relatively pest-free, but in some parts of the US the viburnum leaf beetle can be a serious pest in both landscape and natural settings. Potential diseases include bacterial leaf spot and powdery mildew. INSECTS Viburnum Leaf Beetle, Pyrrhalta viburni, is a leaf-feeding insect native to Europe and Asia. In North America, the beetle became established around Ottawa, Canada in the 1970’s and was first detected in the United States in Maine in 1994 and in New York in 1996. It has since spread through much of the northeastern US (15). Reports of viburnum leaf beetle in the Midwest include Ohio, Michigan, Wisconsin and Illinois (1) and Washington and British Columbia, Canada in the Pacific Northwest (7). The beetle is host-specific and feeds only on Viburnum, but there are preferences within the genus (6). Species with thick leaves tend to be more resistant and feeding is more likely to occur on plants grown in the shade (17). Feeding by both larvae and adults causes tattered leaves and may result in extensive defoliation – repeated defoliations can kill the plant.

  • Department of Planning and Zoning
    Department of Planning and Zoning Subject: Howard County Landscape Manual Updates: Recommended Street Tree List (Appendix B) and Recommended Plant List (Appendix C) - Effective July 1, 2010 To: DLD Review Staff Homebuilders Committee From: Kent Sheubrooks, Acting Chief Division of Land Development Date: July 1, 2010 Purpose: The purpose of this policy memorandum is to update the Recommended Plant Lists presently contained in the Landscape Manual. The plant lists were created for the first edition of the Manual in 1993 before information was available about invasive qualities of certain recommended plants contained in those lists (Norway Maple, Bradford Pear, etc.). Additionally, diseases and pests have made some other plants undesirable (Ash, Austrian Pine, etc.). The Howard County General Plan 2000 and subsequent environmental and community planning publications such as the Route 1 and Route 40 Manuals and the Green Neighborhood Design Guidelines have promoted the desirability of using native plants in landscape plantings. Therefore, this policy seeks to update the Recommended Plant Lists by identifying invasive plant species and disease or pest ridden plants for their removal and prohibition from further planting in Howard County and to add other available native plants which have desirable characteristics for street tree or general landscape use for inclusion on the Recommended Plant Lists. Please note that a comprehensive review of the street tree and landscape tree lists were conducted for the purpose of this update, however, only

The mpI ortance of Geographic and Biological Variables in Predicting the Naturalization of Non-Native Woody Plants in the Upper Midwest Abstract The es lection, introduction, and cultivation of non-native woody plants beyond their native ranges can have great benefits, but also unintended consequences. Among these consequences is the tendency for some species to naturalize and become invasive pests in new environments to which they were introduced. In lieu of lengthy and costly field trials, risk-assessment models can be used to predict the likelihood of naturalization.

  • Rhodotypos Scandens Common Name: Black Jetbead Family Name
    Plant Profiles: HORT 2241 Landscape Plants I Botanical Name: Rhodotypos scandens Common Name: black jetbead Family Name: Rosaceae –rose family General Description: Rhodotypos scandens is a tough, adaptable flowering shrub. It has white flowers in late spring, handsome leaves during the summer and fall, and interesting small black fruits that hold on during the winter. It does well in sun or dense shade and is tolerant of a wide variety of landscape conditions. Rhodotypos scandens was introduced from Asia for use as an ornamental plant but has become an invasive species in eastern United States. Though not a widespread problem in this area, it has been documented in natural areas in DuPage, Cook and a few other areas on the Chicago area. Zone: 4-8 Resources Consulted: Dirr, Michael A.

We determined the species richness of Northeast Asia at various spatial scales, analyzed the floristic relationships among geographic regions within Northeast Asia, and compared the flora of Northeast Asia with surrounding floras. The flora of Northeast Asia consists of 971 genera and 4953 species of native vascular plants. Based on their worldwide distributions, the 971 gen- era were grouped into fourteen phytogeographic elements. Over 900 species of vascular plants are endemic to Northeast Asia. Northeast Asia shares 39% of its species with eastern Siberia-Mongolia, 24% with Europe, 16.2% with western North America, and 12.4% with eastern North America.

  • Diversity in Host Preference of Rotylenchus Spp. Y.S
    International Journal of Science, Environment ISSN 2278-3687 (O) and Technology, Vol. 7, No 5, 2018, 1786 – 1793 2277-663X (P) DIVERSITY IN HOST PREFERENCE OF ROTYLENCHUS SPP. Y.S. Rathore Principal Scientist (Retd.), Indian Institute of Pulses Research, Kanpur -208024 (U.P.) E-mail: [email protected] Abstract: Species of the genus Rotylenchus are ecto- or semi-endo parasites and feed on roots of their host plants. In the study it was found that 50% species of Rotylenchus were monophagous and mostly on plants in the clade Rosids followed by monocots, Asterids and gymnosperms. In general, Rosids and Asterids combined parasitized more than 50% host species followed by monocots. Though food preference was species specific but by and large woody plants were preferred from very primitive families like Magnoliaceae and Lauraceae to representatives of advanced families. Woody plants like pines and others made a substantial contribution in the host range of Rotylenchus. Maximum number of Rotylenchus species harboured plants in families Poaceae (monocots), Rosaceae (Rosids) and Oleaceae (Asterids) followed by Fabaceae, Fagaceae, Asteraceae and Pinaceae. It is, therefore, suggested that agricultural crops should be grown far away from wild vegetation and forest plantations. Keywords: Rotylenchus, Magnoliids, Rosids, Asterids, Gymnosperms, Host preference. INTRODUCTION Species of the genus Rotylenchus (Nematoda: Haplolaimidae) are migratory ectoparasites and browse on the surface of roots. The damage caused by them is usually limited to necrosis of penetrated cells (1). However, species with longer stylet penetrate to tissues more deeply and killing more cells and called as semi-endoparasites (2,3). The genus contains 97 nominal species which parasitize on a wide range of wild and cultivated plants worldwide (3).

  • IHCA Recommended Plant List
    Residential Architectural Review Committee Recommended Plant List Plant Materials The following plant materials are intended to guide tree and shrub ADDITIONS to residential landscapes at Issaquah Highlands. Lot sizes, shade, wind and other factors place size and growth constraints on plants, especially trees, which are suitable for addition to existing landscapes. Other plant materials may be considered that have these characteristics and similar maintenance requirements. Additional species and varieties may be selected if authorized by the Issaquah Highlands Architectural Review Committee. This list is not exhaustive but does cover most of the “good doers” for Issaquah Highlands. Our microclimate is colder and harsher than those closer to Puget Sound. Plants not listed should be used with caution if their performance has not been observed at Issaquah Highlands. * Drought-tolerant plant ** Requires well-drained soil DECIDUOUS TREES: Small • Acer circinatum – Vine Maple • Acer griseum – Paperbark Maple • *Acer ginnala – Amur Maple • Oxydendrum arboreum – Sourwood • Acer palmation – Japanese Maple • *Prunus cerasifera var. – Purple Leaf Plum varieties • Amelanchier var. – Serviceberry varieties • Styrax japonicus – Japanese Snowbell • Cornus species, esp. kousa Medium • Acer rufinerve – Redvein Maple • Cornus florida (flowering dogwood) • *Acer pseudoplatanus – Sycamore Maple • Acer palmatum (Japanese maple, many) • • *Carpinus betulus – European Hornbeam Stewartia species (several) • *Parrotia persica – Persian Parrotia Columnar Narrow
