This is the fifth 2006 edition of the Buckeye Yard and Garden Line (BYGL).
BYGL is developed from a Tuesday morning conference call of Extension
agents, specialists and other contributors in Ohio.
BYGL is also made available on the Internet from the Ohio State University
Horticulture and Crop Science (HCS) in Virtual Perspective website
(http://bygl.osu.edu). Additional fact sheet information on any of
these articles may be found through the OSU fact sheet database (http://plantfacts.osu.edu).
BYGL is a service of OSU Extension and is aided by major support
from the Ohio Nursery and Landscape Association (ONLA), with additional
funding from the Ohio Chapter of the International Society of Arboriculture
(ISA) to the OSU Extension Nursery Landscape, and Turf Team (ENLTT).
Participants in the May 02, 2006 conference included: Pam Bennett (Clark), Barb Bloetscher (Entomology/C. Wayne Ellett Plant and Pest Diagnostic Clinic), Joe Boggs (Hamilton/OSU Extension Center at Piketon), Dave Shetlar (Entomology), Amy Stone (Lucas), Nancy Taylor (Plant Pathology/CWEPPDC), and Curtis Young (Allen).

GDD (GROWING DEGREE DAYS)
GDD is a measure of the daily maximum and minimum temperature and directly relates to growth and development of plants and insects. The GDD of any zip code location in Ohio is estimated using the GDD of ten OARDC weather stations and available on the web at the site below.
The range of GDD accumulations in Ohio from north to south is 231 to 460. Following is a report of GDD for several locations around Ohio as of May 3, 2006: Painesville, 231; Cleveland, 246; Toledo, 269; Youngstown, 270; Lima, 297; Wooster, 305; Coshocton, 338; Columbus, 372; Springfield, 328; Dayton, 347; Cincinnati, 389; Ironton, 440; Portsmouth, 442; and Piketon, 460.
To put these GDD accumulations into perspective, the following is an abbreviated listing of plant and insect species with their respective phenological event and average GDD accumulations at which these events occur. Due to variations in weather, temperature, humidity, etc., these events may occur a few days earlier or later than predicted by the average GDD. By looking at a city, town, or village near you from the above list, or visiting the above web site, you can see what could be taking place in the landscape around you.
Alder leafminer, adult emergence, 224; honeylocust plant bug, egg hatch, 230; common lilac, first bloom, 234; Ohio buckeye, first bloom, 245; eastern redbud, full bloom, 245; common horse chestnut, first bloom, 251; hawthorn lace bug, adult emergence, 253; hawthorn leafminer, adult emergence, 260; flowering dogwood, first bloom, 263; red buckeye, first bloom, 265; Blackhaw viburnum, first bloom, 269; imported willow leaf beetle, adult emergence, 274; Sargent crabapple, full bloom, 298; red horsechestnut, first bloom, 304; pine needle scale, egg hatch - 1st generation, 305; cooley spruce gall adelgid, egg hatch, 308; eastern spruce gall adelgid, egg hatch, 308; common lilac, full bloom, 315; Winter King hawthorn, first bloom, 328; lilac borer, adult emergence, 330; Ohio buckeye, full bloom, 374; holly leafminer, adult emergence, 375; Vanhoutte spirea, full bloom, 406; euonymus scale (first generation), egg hatch, 406; black cherry, full bloom, 419; Miss Kim Manchurian lilac, first bloom, 422; locust leafminer, adult emergence, 437; doublefile viburnum, full bloom, 444; and black locust, first bloom, 467.

WOODY PLANT OF THE WEEK
Red Buckeye Aesculus pavia is a small, disease resistant, native tree that reaches between 15 - 25' or more. Its bright red upright flowers are stunning. If does well in moist soils and in partly shaded to sunny sites. Check this plant and others out in ONLA's Landscape Plants for Ohio.
|
|
PERENNIAL OF THE WEEK
Japanese Tree Peony Paeonia suffruticosa - These displays of beauty are beginning to bloom in central Ohio. The tree peony forms a woody stem that does not die back but drops its leaves in the winter. Therefore, they don't require pruning as they become shrub-like. These plants prefer a rich, well-drained loamy soil; however, most Ohioans are also quite successful with these plants in clay soils. Place them in a somewhat protected area so that the wind doesn't break stems. Numerous colors and cultivars are available. One more thought, ants are attracted to the buds of peonies but its a myth that they are necessary to open the flower bud.

PURPLE MALE CONES
Curtis Young has observed and received many questions about heavy male cone production on Norway spruce Picea abies. Two things will happen with heavy male cone production: 1) as the cones mature, they dry out, open, and release vast quantities of bright yellow colored pollen grains; and 2) as the male cones finish dumping their pollen loads, the cones will die and turn brown.
Consequences of these two events are: 1) heavy shedding of pollen may cover numerous articles under or near the trees such as cars, driveways, sidewalks and furniture. 2) the dead male cones may be mistaken for dead terminal growth. Be aware that neither of these is problematic. The pollen shed will be done very soon and the male cones will fall away leaving no sign of their presence.
Other conifer species, including Austrian pine Pinus nigra and Scots pine P. sylvestris, have yet to shed their pollen. Checking their branches reveals that they too have large numbers of male cones still developing thus, the yellow dusting of items will continue for a few more weeks.

A GALLING REPORT
Cincinnati BYGLive! participants were treated to a wide variety of oak galls, no doubt due to Joe Boggs' intemperate (unhealthy?) fascination with plant galls! The group discussed some of the finer points of galls including the fact that these unusual growths are plant structures that are induced and directed by a "gall-maker" which may be a specific insect, mite, nematode, or a number of other organisms.
Indeed, most plant galls are so specific that the gall-maker may be identified to species just by observing the gall, without benefit of actually observing the gall-maker. Since the gall-maker must orchestrate the growth of the gall, these unique plant structures can only develop on developing plant tissue. For example, once leaves are fully expanded, leaf galls cannot be initiated.
Oaks are known to host almost 800 different types of galls. Only two stand out as being consistently destructive to their host; namely the HORNED OAK GALL and OAK GOUTY GALL. Both of these stem galls arise from twigs and branches, and are caused by tiny wasps that belong to the family Cynipidae. These galls harm oaks by incorporating vascular tissue within their structure. The tissue may become so disorganized that vascular flow of water and nutrients are disrupted causing branches and twigs beyond the gall to die.
The two oak galls most evident to the BYGLive! participants were the OAK APPLE GALL produced by the Cynipid wasp Amphibolips confluenta, and the WOOL SOWER GALL produced by the Cynipid wasp Callirhytis seminator. The aptly named oak apple galls are around 1/ 2" - 2" in diameter. They arise from the leaf midribs or petioles of red, black, and scarlet oaks. Currently, the immature galls were light green in color, and filled with a spongy greenish-white material that is not unlike the flesh of an apple. The galls will mature rapidly, becoming light brown in color, and their surfaces will become thin, papery shells. Opening the galls will reveal a mass of fibers radiating from a central seed-like structure that contains a single maturing wasp.
Wool sower galls look like white cotton balls 1" - 2" in diameter. They arise from leaf buds. Opening the galls will reveal a collection of green seed-like structures, each containing a single wasp larva. The galls will eventually mature into almost circular, light-brown structures with a slightly hardened surface. Both the oak apple and wool sower galls are dramatic looking, but neither cause significant harm to their hosts.

AN EMERALD ASH BORER LOOK-A-LIKE
Joe Boggs is receiving phone calls from Ohioans concerned that the emerald green beetles currently cruising wood-lots and forests in the southern part of the state, are the dreaded emerald ash borer Agrilus planipennis. The green beetle in question is actually a native insect, and it is a predator with a very predatory-sounding name, the SIX-SPOTTED [GREEN] TIGER BEETLE Cicindela sexguttata.
Tiger beetles belong to the "tiger beetle family," Cicindelidae. The common name for this family is descriptive since all tiger beetles are ferocious predators. Adults seize their arthropod prey with powerful sickle-shaped mandibles. The beetles have long legs and are fast runners. They are also very good fliers. As one would expect of a predator, they have excellent eyesight, and their protruding eyes make the beetles look like they are wearing goggles.
Most tiger beetles have a shiny metallic color. This can create confusion with Agrilus beetles, which share similar colors and are commonly called "metallic wood borers." Tiger beetles have elongated bodies, but the thorax is usually about half the width of the front wings and abdomen. The thorax of Agrilus beetles is almost the same width as the abdomen.
The six-spotted tiger beetle's fine eyesight, quick speed, and flying agility makes it difficult for people to get a close look at the beetles, hampering positive identifications. Their green color is actually more "emerald" in color than emerald ash borer. As the name implies, the six-spotted green tiger beetle has spots that are white and arranged along the trailing edge of the wing covers, three per side, however, the spots are small and the highly reflective light bouncing off their shiny green color, sometimes obscures these spots. Green tiger beetles are common insects in the woods of Ohio, and they seem to prefer zipping around forest paths. Look close ... tiger beetles are real tigers of the insect world!

MOUND-BUILDING ANTS
Barbara Bloetscher of the CWEPPDC has received a number of phone calls from homeowners reporting large ant mounds in their landscapes. Dave Shetlar noted that the most likely culprits were either ALLEGHENY MOUND ANTS Formica excectoides, or BLACK FIELD ANTS F. subsericea.
Allegheny mound ants are one of the true mound-builders of the ant world. Their dome-shaped mounds may be several feet in diameter, and reach a dizzying ant-height of 30". Mound ants range in color from chestnut red, to black, to a combination of red and black. The ants are very aggressive, and they can use their powerful mandibles to deliver a noticeable pinching bite to a probing finger. However, their threat to people is inconsequential compared to their impact on plants.
Mound ants are capable of killing small bushes and trees by injecting formic acid into wounds created by their mandibles. They use this capability to clear plants that shade their mounds. All vegetation, with the exception of large trees, may be killed within 40-50' of large, well-established mounds. They have a deserved reputation of being a serious nursery and Christmas tree production pest.
Black field ants are much less accomplished mound-builders. They form large, low-profile mounds of loose soil. These ants do not inject formic acid into plants, so they are not direct plant killers. However, they often heap soil over low-growing plants and they will pile soil high onto plant stems. Their plant-smothering mounds have been known to cause plants to decline and die. In particular, they are sometimes considered a serious pest of turfgrass. These large black ants are also very aggressive, and they will attempt to bite using their powerful, well developed mandibles.
Although both Allegheny mound ants and black field ants will protect, or "tend," plant-sucking insects such as aphids, and they will feed on honeydew produced by these insects, the ants are also very effective predators. Both species may be observed dragging (presumably kicking and screaming) their victims back to their mounds to be surgically dismantled for protein.
Since both species are considered beneficial insects, management efforts should focus on plant protection. Both species of ants can be persuaded to move by repeated destruction of their mounds. If a more powerful management tool is needed, some of the ant bait products may provide relief. As with all insecticides, applicators must read and follow label directions.

EMERALD ASH BORER QUARANTINE GROWS
Ohio's emerald ash borer (EAB) quarantine was expanded earlier this week to include an additional portion of central Ohio; Orange Township in Delaware County. The majority of the state's infestation is in northwest Ohio, where quarantines exist in 14 counties.
In Ohio, violators caught moving restricted materials that include ash logs, trees, nursery stock, chips larger than 1", and all non-coniferous firewood can face fines of up to $4,000 levied by the Ohio Department of Agriculture (ODA). ODA also noted in the media release to the press that cases in which courts in Fulton, Hancock, and Wood counties recently issued $1,600 in fines against 9 Ohio residents and 4 Michigan residents for such violations.
It is important to note that if you are located within a quarantine area, it is illegal to remove any banned materials from that area. This includes any ash wood samples that you may have collected because you are curious if you have EAB. If you believe that you have EAB, contact the ODA at 877-OHIO-EAB. As the beginning of adult flight season approaches, the movement of any potentially infested material could spread the insect further. Diagnostic check-off lists, and other valuable resources can be found on the Ohio State University Extension's EAB website, Ash Alert, at http://ashalert.osu.edu/ . For more information, check the ODA website for the latest regulatory information below.

WINDSHIELD WIPES
BYGLers also ran into some other insects and mites this week including:
* Joe Boggs noted that FOREST TENT CATERPILLARS Malacosoma disstria continue to creep up the list of "most frequently asked questions" to Extensioneers in southwest Ohio. Dave Shetlar reported the moth caterpillars are also making themselves known in the central part of the state. The caterpillars may be seen dangling from silk threads, marching up and down tree trunks and branches, or simply showing up crawling on gardeners and nature enthusiasts. Most caterpillars are just now reaching the third instar stage, so the onslaught will continue for a few more weeks. See last weeks BYGL (BYGL 2006-4, 4/27/06) for more information on this general defoliator.
* EASTERN TENT CATERPILLARS M. disstria appear to be reaching the zenith of their spring escapades in southern Ohio. Unlike their forest tent cousins, these moth caterpillars construct very obvious silk nests in branch forks of trees in the Rosaceae family, particularly cherry. The nests are now huge, and in many cases the caterpillars have stripped the foliage from their unfortunate host trees. This signals the beginning of a change in behavior where the caterpillars will crawl from their hosts and go on a crawl-about in search of other food. The wandering caterpillars may appear in many unexpected places, including on plants not normally associated with this insect. Fortunately, this behavioral change also means the caterpillars are almost done for the season.
* HONEYLOCUST PLANT BUG Diaphnocoris chlorionis nymphs are now being found scurrying amongst the expanding foliage of their namesake in southwest Ohio. Feeding by these lime-green sucking insects can cause the new foliage to become twisted, stunted, and occasionally discolored. Their feeding injury may mimic symptoms produced by growth regulator herbicides. Examine expanding leaflets carefully since the nymphs are very mobile and they scramble away from probing fingers. It has been generally recommended that a control application be considered if more than 5 nymphs are found per leaf.

DISEASE DIGEST
|
VOLUTELLA LEAF BLIGHT AND STEM CANKER OF PACHYSANDRA
Nancy Taylor reported that this common disease is showing its two faces again this spring, with samples coming in to the PPDC. Symptoms include a zonate spotting on the foliage and blackened blighting of the stems. To determine if observed stem discoloration and wilting on pachysandra are caused by this fungus (Volutella pachysandricola), put some samples in a plastic bag and wait for a few days. Orangish-pick spore masses of the fungus develop in the cankered areas.
Fungicide applications can help, if you make multiple applications during periods of active growth of the pachysandra, which unfortunately encompasses much of the growing season. Cultural management may be the more practical approach. Infected plantings should be mowed to 1"- 2", and all diseased and mowed tissue should be removed and destroyed. Overhead irrigation should also be avoided, if practical. Mowing every 3-4 years in early spring is also helpful in dense, older pachysandra plantings for which mowing is sometimes a useful renovation technique as well as a disease prevention tool.

SUDDEN PINE DEATH
Curtis Young reported observing two Austrian pines (Pinus nigra) that appear to be rapidly dying. Both trees are about 15' tall and fully branched from top to bottom. Neither tree appears to be suffering from Diplodia Sphaeropsis tip blight, yet each tree over the past couple of weeks has rapidly changed from the dull green color that pines develop through the winter, to a gray-green, to tan, to brown. Based on the limited information that was described on the conference call, Nancy Taylor suggested that it could have been caused by the PINEWOOD NEMATODE Bursaphelenchus xylophilus resulting in PINE WILT DISEASE. Nancy also added that the only sure way to tell is to collect proper samples and send them to the C. Wayne Ellett Plant and Pest Diagnostic Clinic in Columbus for analysis.
The pinewood nematode attacks a multitude of pine species; however, Japanese black pine (P. thunbergii), Japanese red pine (P. densiflora) and Scots pine (P. sylvestris) are the most susceptible. It seems that most U.S. pine species are somewhat resistant to the disease. In addition to pine, the nematode has been isolated from larch, balsam fir, spruce and deodar and atlas cedar.
Symptoms of pine-wilt disease occur rapidly usually in late spring or summer. Some of the symptoms include: a lack of resin flow from barks wounds; foliage becomes pale green, then yellow and finally reddish brown when the tree succumbs to the disease; and the wood in diseased trees is dry and totally lacks resin. Symptoms usually become evident throughout the entire crown at once in susceptible species.
Research has shown that the pinewood nematode is moved from host to host by pine sawyer beetles, a longhorned beetle in the Family Cerambycidae. These beetles breed in dead and recently killed pines. The developing beetles become contaminated with the pinewood nematode. When the beetles complete development, adults emerge from the wood carrying the nematode and fly to healthy pines where they feed on succulent pine and introduce the nematode into feeding wounds.
The only way to confirm the presence of pinewood nematode is to take wood samples from symptomatic trees and send them to the plant diagnostic laboratory. Wood samples (not bark) should be obtained from trunk or branches preferably in the lower, middle, and upper portions of the crown. Wood cores obtained with an increment borer, or one to two-inch-thick cross-sections of the trunk or branch are suitable samples. Wrap samples in paper, not plastic, for shipment (enclosing the sample in plastic may kill the nematodes).
Management of the pinewood nematode requires immediate removal and destruction of pines killed by the nematode to help prevent spread of the pest to adjacent, healthy pines. Wood from the dead pines should be chipped, buried in a landfill, or immediately burned. Maintaining the vigor of pines through periodic fertilization and irrigation during dry periods may help prevent disease development.

TURF TIPS
|
BETTER TREATMENT FOR ATAENIUS BEETLES
In last week's BYGL, we recommended treating Ataenius beetles preventively with imidacloprid or thiamethoxam when the Vanhoutte spirea blooms (early May). This recommendation must be amended. Dave Shetlar is recommending using clothianidin (Arena) instead of thiamethoxam. Arena not only has good control of annual white grubs, billbugs and chinchbugs, but it also takes out turfgrass caterpillars as well. For more information refer to
http://hcs.osu.edu/sportsturf/notes/detail.lasso?id=1001

|
ROUGHSTALK BLUEGRASS APPEARS AGAIN!
Several BYGLers reported that turfgrasses seem to have different shades of green, due to a variety of reasons. One reoccurring problem is the encroachment of roughstalk bluegrass, Poa trivialis.
Roughstalk bluegrass is a cousin to Kentucky bluegrass with a fine textured, light green color, however, it spreads by creeping above-ground stems (stolons) instead of underground stems (rhizomes) as its cousin does. Its stemmy, prostrate growth habit prevents close mowing, and during cool, wet weather, it quickly grows over the top of other grasses inhibiting their growth. Once temperatures climb and remain hot, roughstalk bluegrass turns brown and recedes. At this point, large patches of the grass suddenly appear dead. These areas may recover in the fall or the next spring, and escape the attention of the casual observer. Unfortunately, it is often misdiagnosed and treated as a turfgrass disease instead of a weed.
This perennial weed can be controlled using a systemic, non-residual, postemergent herbicide (e.g. glyphosate, or glufosinate. Multiple applications must be used with re-application as regrowth occurs. Once the herbicide has completely eliminated the roughstalk bluegrass, the affected area can be repaired by properly seeding or sodding, using the same species and cultivars found in the surrounding turfgrass.

INDUSTRY INSIGHT

CALICO SCALE CONTROL
Larry Hanks (Pampered Properties, Inc., Lexington, KY) shared with the participants of this week's BYGLive! in Cincinnati the "just-in" results of insecticide efficacy trials targeting calico scale (Eulecanium cerasorum) females in central Kentucky. Applications of TalstarOne Multi-Insecticide (7.9% bifenthrin) were made at a rate of 20 ounces per 100 gal. of water by Larry and Dan Potter (Entomology, University of Kentucky) to zelkova trees infested with the scale. Dan's application was made on 4/19/06, and Larry's application was made on 4/20/06. Larry's application included "Breakthrough" spreader-sticker at a rate of ounces per 100 gal. of water in his application.
While the inclusion of the spreader-sticker produced a more rapid mortality, both applications resulted in 100% efficacy with the populations being eliminated in less than 10 days. Larry graphically summarized the overall results by stating "the scales were fried!" Indeed, he showed photographs showing the scales had not only collapsed, but were also peeling away from their host trees. The timing and results demonstrated this application can have a significant impact on overall population reduction since the females could have produced more than 4,500 eggs per female later this spring.
The calico scale is a globular, blackish-brown soft scale that is about 1/4" in diameter. It is easy to recognize because of the distinct rows of squarish, white patches on the back. This scale can infest a wide variety of deciduous trees including honeylocust, maple, magnolia, sweetgum, ornamental fruit trees, dogwood, as well as the aforementioned zelkova. High populations and significant damage has been experienced in central Kentucky, and the scale has been appearing in increasing numbers in Ohio. Aside from stressing their hosts by sucking plant juices, calico scale is also a prolific producer of honeydew.
Dave Shetlar noted that trials in Ohio have indicated calico scale can also be managed using soil drenches of neonicotinoid systemic insecticides such as imidacloprid (e.g. Merit, Marathon), clothianidin (e.g. Arena), and dinotefuran (e.g. Safari) made from September into November. Dave also indicated that excellent results may also be achieved by making soil drench applications in late-June to early-July targeting first and second instar nymphs as they settle to feed on leaves.

USDA DIGNITARIES CELEBRATE ARBOR DAY IN OHIO
"Plant Hope" was the theme at the Arbor Day event last Friday on the campus of the Sisters of St. Francis, just outside of Toledo. Mark Rey, Under-Secretary of the United States Department of Agriculture and Ohio Representative Marcy Kaptur were in attendance to encourage people to plant trees to help preserve the region's appeal, especially in light of the discovery of EAB. The Sisters also gave away 700 seedlings that were donated by the Ohio Department of Natural Resources (ODNR).
As part of the event, Mr. Rey brought with him 2 chestnut blight resistant chestnut trees that were planted on the campus. Two additional trees were planted in Columbus later that afternoon. "What those trees symbolize is that you should never give up hope," Mr. Rey said as he spoke to nearly 150 people.
