Control of Callery Pear in Pastures, Right-Of-Way, and Natural Areas
CONTROL OF CALLERY PEAR IN PASTURES, RIGHT-OF-WAY, AND NATURAL AREAS Scott Flynn, PhD (Dow AgroSciences LLC) Reid Smeda, PhD, and Carey Page (University of Missouri) www.RangeAndPasture.com www.RangeAndPasture.com Overview • Pyrus calleryana Dcne. (Rosales: Rosaceae) is quickly becoming one of the most widespread, aggressive invaders of ROWs, and Pastures. Currently some states have convinced nurseries, and big box stores to stop the sale of ornamental pears to slow the spread. To-date there have been no products labeled for Pyrus calleryana control in the US. ™®Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow www.RangeAndPasture.com Background • P. calleryana was introduced to the US by Frank Reimer, Southern Oregon Experiment Station, to combat fire blight in common pear (Pyrus communis). • Native of Southeast Asia • Common varieties > ‘Bradford’ – 1962, Maryland > ‘Chanticleer’ - mid-1965 Ohio • Select’, ‘Stone Hill’, ‘Select’, and ‘Glenn’s Form’ > ‘Aristocrat’ – 1969, Kentucky > ‘Whitehouse’ – 1977, Maryland > ‘Autumn Blaze’ – 1878, Oregon > ‘Capital’ – 1982, Washington DC Culley and Hardiman (2007) ™®Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow www.RangeAndPasture.com Range and Adaptation Comparison of adaptation of Pyrus calleryana between the US and China based on similar latitudes.

Pyrus Calleryana 'Aristocrat' 'Aristocrat' Callery Pear
Fact Sheet ST-536 October 1994 Pyrus calleryana ‘Aristocrat’ ‘Aristocrat’ Callery Pear1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION ‘Aristocrat’ Callery Pear quickly grows 35 to 45 feet high and 30 to 35 feet wide, with widely-spaced, upright-spreading, thornless branches (Fig. 1). The more dominant trunk and open form of ‘Aristocrat’ Callery Pear helps to make it less susceptible to wind and ice damage than ‘Bradford’. Branch angles are wider and lateral branches grow at a slower rate than on ‘Bradford’, therefore the branches are better attached to the trunk. In spring before the new leaves unfold, the tree puts on a brilliant display of pure white flowers which, unfortunately, do not have a pleasant fragrance. The leaves emerge as red/purple, then become 1.5 to 3 inches long, glossy green with wavy margins and a red blush. They turn red again in fall before dropping. The small, pea-sized, red/brown fruits which form are quite attractive to birds and other wildlife, and mummify on the tree persisting for several months to a year. Planting two or more cultivars of Callery Pear together could increase fruit set. GENERAL INFORMATION Figure 1. Young ‘Aristocrat’ Callery Pear.

Origin, Domestication, and Dispersing of Pear (Pyrus Spp.)

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The pear (Pyrus communis L.) is a typical fruit of temperate regions, having its origin and domestication at two different points, China and Asia Minor until the Middle East. It is the fifth most widely produced fruit in the world, being produced mainly in China, Europe, and the United States. Pear belongs to rosaceous family, being a close “cousin” of the apple, but with some particularities that make this fruit special with a delicate flavor. Thus, it deserves a special attention and a meticulous review of all the history involved, and the recent research devoted to it, because of the economic and cultural importance of this fruit in a range of countries and cultures. Therefore, the purpose of this literature review is to approach the history of the origin, domestication, and dispersal of pears, as well as reporting their botany, their current scenario in the world, and their breeding and conservation.

The Rise and Fall of the Ornamental Callery Pear Tree
The Rise and Fall of the Ornamental Callery Pear Tree Theresa M. Culley ne of the most notable heralds of spring in the eastern United States Ois the profuse blooming of orna- mental pear trees in front yards and along ARCHIVES OF THE ARNOLD ARBORETUM city streets. The Callery pear (Pyrus calleryana), and particularly its many cultivars such as ‘Bradford’, ‘Cleveland Select’, and ‘Aristocrat’, has become one of the most popular ornamental trees in North America. However, its commercial success has now become overshadowed by its tendency to spread along roadways and into natural areas through reseeding. Today this tree is considered invasive in many states, in stark contrast to how it grows in its native range in Asia. How did this tree become the scourge of land man- agers across North America? What has led to its fall from grace? To understand this fascinating story, we need to start at the beginning. Seeds From China Plant collector Frank N. Meyer in China in 1908. Toward the end of the nineteenth century, farm- stamina to tolerate the physical discomforts ing began to replace ranching in the western and social isolation of travelling for months in United States and there was a growing demand distant lands.

This research reflects the data available at the time this evaluation was conducted. General Information Status: Completed Screener: Emily Russell Evaluation Date: August 23, 2017 Plant Information Plant: Pyrus calleryana 'Bradford' If the plant is a cultivar, how does its behavior differs from its parent's? 'Bradford' was the first selection of Pyrus calleryana to become commercially available in the United States in 1962. 'Bradford' was selected at the USDA Plant Introduction Station in Glenn Dale, Maryland. The crown is pyramidal with densely packed branches which are prone to structural problems and breakage, more so than later cultivars. 'Bradford', however, is the most fireblight-resistant cultivar. It is thornless, unlike the species, but is often grafted onto seedling rootstock in the nursery trade. It is self- incompatible but does produce fertile fruit after pollination by other cultivars.

Pyrus Calleryana ‘Aristocrat’ (Callery Pear)
FEATURED TREE Pyrus calleryana ‘Aristocrat’ (Callery Pear) Notes Prune trees early in their life to space lateral branches along a central trunk, otherwise not a lot of pruning required to develop good structure. Only buy trees with well-spaced branches. Tree will require periodic crown lifting to maintain clearances. Fruit are persistent on tree with no significant litter problem. Origin A cultivated variety Habit Medium deciduous tree with an oval to pyramidal form. Mature height of about 10-12m x 7-10m wide. Description Dense crown of foliage. Leaves are dark green glossy, simple, ovate with undulating margins, alternating on thornless branches, turning red in autumn. Thin, grey-black bark, which can be damaged by mechanical impact. Flowers are pure white and profuse in spring followed by small, pea-sized, red/brown fruits. Tolerances Tolerates a wide range of soil conditions including both slightly alkaline and acid soils. Tolerant of drought, poorly drained soils, compaction and air pollution. Grows well in limited soil space in urban areas. Transplants easily. Uses & management ‘Aristocrat’ pear is very susceptible to fire blight (Not an immediate concern in Australia). Trees can be infested with aphids and scale. Borers can attack damaged areas. Good street tree, car parks, pavement cut outs other restricted soil spaces. Reference Gilman, E.
