Disease and Insect Resistant Ornamental Plants Mary Thurn, Elizabeth Lamb, and Brian Eshenaur New York State Integrated Pest Management Program, Cornell University nysipm.cornell.edu 2019 Search for this title at the NYSIPM Publications collection: ecommons.cornell.edu/handle/1813/41246 Disease and Insect Resistant Ornamental Plants Mary Thurn, Elizabeth Lamb, and Brian Eshenaur New York State Integrated Pest Management Program, Cornell University Pyracantha Firethorn Pyracantha is a small genus of spiny evergreen shrubs in the rose family. White flowers are followed by a showy display of bright red, orange or yellow fruit which persist into fall and winter. Aside from their ornamental interest, the dense thorny growth habit provides a natural barrier and cover for wildlife. Like other members of the rose family, Pyracan- tha is susceptible to several diseases, including scab and fire blight. There are resistant cultivars and hybrids available. DISEASES Scab is a disease caused by the fungus Venturia inaequalis f.sp. pyracanthae, formerly known as Spilocaea pyracanthae (13). Perhaps the most important disease of Pyracantha, it occurs across the United States and Canada and is believed to have been imported from Europe. The disease spreads during rainy or humid weather. Infection is more common on fruit than leaves, and may result in premature leaf drop and blackening of the fruit.

Named for the scorched appearance of affected leaves, blossoms and twigs, it can cause severe damage and death in nursery and landscape settings. Fire blight is favored by warm, humid weather, so it is especially prevalent in the Southeast. Insects and rain can spread the bacteria. Cultural practices that prolong succulent growth such as excess fertilization and heavy pruning can increase disease incidence and severity.

Many plants in the rose family are susceptible, but Pyracantha is a preferred host. Lace bugs feed on the underside of leaves creating small chlorotic spots visible mostly on the upper surface. Damage is unsightly and may spread to cover the entire leaf surface. Repeated infestations decrease plant vigor and may result in death of the plant. In a caged feeding study, researchers report P. atalantiodes ‘Aurea' was a less preferred host compared with P. coccinea ‘Orange Glow' and ‘Loboy', P. koidzumii ‘Ingleside Crimson', and P. angustifolia ‘Varie- gata' (12). Japanese Beetle, Popillia japonica, is a common foliage feeder of many landscape plants. Some resistance is reported for P. coccinea with only occasional feeding observed (9). REFERENCES 1.

  • Baies... 8. Buisson-Ardent Gui Houx
    BAIES ROUGES... 8. BUISSON-ARDENT 1 Pyracantha Pyracantha , communément appelé « Buisson ardent » est un genre botanique de buissons persistants et épineux de la famille des Rosacées , sous-famille des Maloideae . Le mot Pyracantha vient du grec Pyros , le feu et Acantha , l'épine. Le nom de Buisson ardent est une allusion à l'épisode biblique rapporté dans l'Exode 3,2. C'est un proche parent du Cotonéaster , mais les Pyracanthas ont des feuilles dentelées coriaces de 2 à 4 cm de long et de grosses épines alors que le Cotoneaster n'en a pas. Le Pyracantha est originaire du sud de l'Europe et de l'Asie. Il peut atteindre 6 m de haut. Outre son superbe feuillage, il propose de magnifiques baies colorées à l’automne... Il donne, en fin de printemps, des fleurs blanches en corymbe, mellifères (quoique malodorantes) donnant naissance à des pommettes rouge, orange, ou jaune mûres en automne.

Here it is provided the updated checklist of the alien vascular fora of Tuscany. Together with those taxa that are considered alien to the Tuscan vascular fora amounting to 510 units, also locally alien taxa and doubtfully aliens are reported in three additional checklists. The analysis of invasiveness shows that 241 taxa are casual, 219 naturalized and 50 invasive. Moreover, 13 taxa are new for the vascular fora of Tuscany, of which one is also new for the Euromediterranean area and two are new for the Mediterranean basin. Keywords: Vascular plants, Xenophytes, New records, Invasive species, Mediterranean. RIASSUNTO. Si fornisce la checklist aggiornata della fora vascolare aliena della regione Toscana. Insieme alla lista dei taxa che si considerano alieni per la Toscana che ammontano a 510 unità, si segnalano in tre ulteriori liste anche i taxa che si ritengono essere presenti nell’area di studio anche con popolazioni non autoctone o per i quali sussistono dubbi sull’effettiva autoctonicità. L’analisi dello status di invasività mostra che 241 taxa sono casuali, 219 naturalizzati e 50 invasivi. Inoltre, 13 taxa rappresentano una novità per la fora vascolare di Toscana, dei quali uno è nuovo anche per l’area Euromediterranea e altri due sono nuovi per il bacino del Mediterraneo. Parole chiave: Piante vascolari, Xenofte, Nuovi ritrovamenti, Specie invasive, Mediterraneo. Introduction establishment of long-lasting economic exchan- ges between close or distant countries. As a result The Mediterranean basin is considered as one of this context, non-native plant species have of the world most biodiverse areas, especially become an important component of the various as far as its vascular fora is concerned.

  • Abies Concolor (White Fir)
    Compiled here is distribution, characteristics and other information on host species featured as ‘Host of the Month’ in past issues of the COMTF Monthly Report. Abies concolor (white fir) This is an evergreen tree native to the mountains of southern Oregon, California, the southern Rocky Mountains, and Baja California. Large and symmetrical, white fir grows 80 – 120ft tall and 15 – 20ft wide in its native range and in the Pacific Northwest. White fir is one of the top timber species found in the Sierra Nevada Mountains of CA and is a popular Christmas tree, as well as one of the most commonly grown native firs in Western gardens. Young trees are conical in shape, but develop a dome-like crown with age. The flattened needles of white fir are silvery blue-green, blunt at the tip , and grow 2 – 3in long. Often curving upwards, the needles extend at right angles from the twig, and twigs produce a citrus smell when needles are broken. White fir is monoecious, producing yellow- to red-toned, catkin-like male flowers and inconspicuous yellow-brown female flowers. The oblong cones grow 3 – 5 in upright, are yellow-green to purple in color, and are deciduous at maturity, dispersing seed in the fall. New twigs are dark- orange, but become gray-green, then gray with maturity. The bark of saplings is thin, smooth, and gray, turning thick, ash-gray with age, and developing deep irregular furrows. P. ramorum- infected Abies concolor (white fir) was first reported in the October 2005 COMTF newsletter as having been found at a Christmas tree farm in the quarantined county of Santa Clara.

  • Plants Resistant Or Susceptible to Armillaria Mellea, the Oak Root Fungus
    Plants Resistant or Susceptible to Armillaria mellea, The Oak Root Fungus Robert D. Raabe Department of Environmental Science and Management University of California , Berkeley Armillaria mellea is a common disease producing fungus found in much of California . It commonly occurs naturally in roots of oaks but does not damage them unless they are weakened by other factors. When oaks are cut down, the fungus moves through the dead wood more rapidly than through living wood and can exist in old roots for many years. It also does this in roots of other infected trees. Infection takes place by roots of susceptible plants coming in contact with roots in which the fungus is active. Some plants are naturally susceptible to being invaded by the fungus. Many plants are resistant to the fungus and though the fungus may infect them, little damage occurs. Such plants, however, if they are weakened in any way may become susceptible and the fungus may kill them. The plants listed here are divided into three groups. Those listed as resistant are rarely damaged by the fungus. Those listed as moderately resistant frequently become infected but rarely are killed by the fungus. Those listed as susceptible are severely infected and usually are killed by the fungus. The fungus is variable in its ability to infect plants and to damage them. Thus in some areas where the fungus occurs, more plant species may be killed than in areas where other strains of the fungus occur. The list is composed of two parts. In Part A, the plants were tested in two ways.

Mycosphere 8(5), 485–511, Doi 10.5943/mycosphere/8/5/1 Abstract The family Rosaceae includes a large number of species ranging from herbaceous (Fragaria) to ornamental plants (Rosa and Pyracantha) and fruit trees (Malus and Pyrus). Diaporthe species have been associated with twig canker, shoot blight, dieback, wood decay and fruit rot on members of the Rosaceae. In this study a collection of isolates from several Rosaceae hosts were characterised by multi-locus sequence analyses using the internal transcribed spacer, translation elongation factor 1-alpha, beta-tubulin, histone H3 and calmodulin loci. The phylogenetic analyses of the combined five loci revealed that the isolates studied were distributed among four clades, of which two correspond to D. foeniculina and D. eres. The other two clades, closely related to D. passiflorae and D. leucospermi represent two new species, D. pyracanthae sp. nov.
