WEATHER WATCH
|
This week's weather summary includes data from August 1 - 9, 2006. This weather summary includes information from 4 OARDC weather stations across the buckeye state.
It is important to note that rainfall amounts can vary greatly in any given area. It was noted that while some areas have received sufficient rainfalls, neighboring areas can be dry. Nothing beats putting a shovel in the ground to assess soil moisture!
Below is a quick rainfall comparison of actual vs. normal or average for the four areas: Perry, 36.84" vs. NA; Hoytville, 25.23" vs. 20.94"; Miami, 27.04" vs. 23.26"; and Jackson, 26.25" vs. 27.74".

PLANTS OF THE WEEK
Read all about perennials and landscape trees and shrubs in the ONLA publications "Perennial Plants for Ohio" and "Landscape Plants for Ohio." The descriptions and photographs of plants were provided for these publications by the OSU ENLT Team along with other industry plant lovers. These full-color publications are available at http://Buckeyegardening.com for $5.00. Click on "garden store" and then "onla plant guides." ONLA members can purchase these in quantities at a reduced price at onla.org.
*PERENNIAL PLANT OF THE WEEK. Summer phlox, (Phlox paniculata). About the time when the blossoms of most well known perennial garden favorites have faded, and are looking a little dull, P. paniculata is at its best! Summer phlox does best in fertile, moist, well drained soils that are located in full sun or partial shade. They are available in whites, pinks, reds, blues, and purples. The clump-forming plant can reach heights from 2-4', and are utilized in the landscape as border plantings. Summer phlox is susceptible to powdery mildew, but selective placement in the garden, careful watering, and other cultural practices can help to minimize the effects of this disease. P. paniculata is blooming right now and can be found in most garden centers around the state.
*WOODY PLANT OF THE WEEK. Rose-of-Sharon, (Hibiscus syriacus). This old garden favorite has earned new life in modern landscapes with many new taxa. It is an increasingly popular shrub or small tree (8-12') with open, showy flowers ranging in colors from whites to reds and purples with many variations of color combinations. Rose-of-Sharon (not related to rose) is adaptable to both alkaline and acid soil pH, as well as most soil types, although you should avoid moisture extremes to the extent possible. This plant provides welcome colorful landscape floral effect for mid summer. The wide range of cultivars includes such taxa as 'Diane', with pure white flowers; 'Helene', in white with throats of splotchy red-purple; and 'Blue Satin'.

SUNBURN ON TREES
(Part 2 of "Tree Maladies Caused by Cold Temperatures") Sunscald damage on trees is common on young, thin barked trees, such as red maple or apple in northern climates where snow cover remains throughout the winter. Alan Siewert, Ohio Department of Natural Resources-Division of Urban Forestry, indicated that when he came to Ohio in 1987, this kind of damage was rare because the snow would periodically melt away during the winter however, in recent years, Northeast Ohio has experienced more persistent snow cover.
Sunscald is a large area of damage, typically located on the southwest side of the tree, beginning 6 - 12" above the ground and extending up about 4' on the tree; although, in certain situations, it can occur on the south side of the tree. Another common name for this type of damage is "southwest winter injury". During late winter or early spring, fluctuating temperatures cause the snow to melt and create a glazed snow cover, which easily reflects the winter sunlight.
The cambium on the southwest side of the tree heats up from the combination of direct sun striking the trunk and the reflected sunlight from the snow. This heating effect causes the water in the cambium layer to melt. With air temperatures below freezing and the decreasing heat from the setting sun, the melted water rapidly begins to re-freeze in the cambium. The freezing water forms crystals, which rupture the cells, causing them to desiccate, cease to function and eventually die. Consequently, those abused cambial areas which are often located on the most exposed portion of the tree trunk, are repeatedly heated and then frozen; therefore, these cambial areas are most often damaged or killed on young, thin-barked trees.
Within a year or two, the sunscald damage becomes visible by forming an area with dead, peeling bark and a sunken hollow formed by the callus roll. The callus roll typically forms and pushes out from the remaining live cambial tissue surrounding the damaged area. The damage often involves about 25-33% of the circumference of the trunk, and the damaged bark will be dark and sloughs off.
To prevent this type of winter injury, young, susceptible trees can be wrapped in the fall with a white or light colored paper or a light colored tree wrap, to reflect the sunlight. These papers or tree wrap should be removed in the spring as the trees begin to leaf out. Tree trunks may also be painted white or whitewashed, using a latex paint, to create that same reflective surface on the tree trunk. Once bark on the trunk has aged and is roughened, sunscald is not usually a problem however, once sunscald damage has occurred, little can be done to correct the problem. Tree health care practices, like proper watering, mulching, pruning, etc. can help fortify a damaged tree against additional stresses.
One of the great challenges of diagnosing an "abiotic disease," such as sunscald, is there are no signs of a pathogen, only those dang, confusing symptoms. There is no pest to easily identify and give a scientific name; therefore, we typically use common names or descriptors of the malady. As with all common names, they may change over time and often become regionally common. What is sun scald in Wisconsin, may be southwest injury in Minnesota. Most abiotic diseases do not come with a standardized scientific name for clarification.

ARACHNAPHOBIA
This is the time of the year when panicked calls to Extension offices concerning spiders begin to balloon. Spiders are predators and populations of these meat eaters take much longer to swell during the growing season, compared to plant eaters. There are over 600 species of spiders found in Ohio, most feed primarily on insects. Some of the more interesting spiders currently being seen include FUNNEL WEB SPIDERS (Family: Agelenidae) and the ORB WEAVERS (Family: Araneidae).
Funnel web spiders produce large, flat, sheet-like webs spun across grass, under rocks or boards, or over the branches of shrubs such as yews and junipers. The webs slope gently towards a narrow funnel or tube where the spider resides, awaiting its next victim. The spiders are medium-sized and resemble small wolf spiders. Funnel webs can become very evident when covered by early morning dew, or when they snare dust during droughty conditions.
Orb weavers are the true master engineers of the spider world. They spin vertical round webs with radiating spokes of structural silk covered by a spiral of sticky silk. One of the most spectacular orb weavers found in Ohio is the GARDEN SPIDER (Argiope aurantia). This large spider has a leg span that can exceed 2". The legs are black with reddish or yellow bands. The mostly black abdomen is conspicuously marked with yellow or yellowish-orange spots and bands. This spider is active during the day and usually spins its web in tall weeds. The spider can be found resting in the middle of the web atop a zig-zag pattern of coarse webbing that reflects ultra-violet light and attracts insects.
Although there are several insecticides labeled for spider control, this is not a recommended practice. Spiders are important in reducing insect pest populations. Homeowners are urged to practice restraint, appreciation, and understanding. Aside from providing free Halloween decorations, spiders also provide a great service by reducing the need for controlling more significant pests.

DON'T KILL THOSE GIANT CATERPILLARS!
Joe Boggs provided a cautionary tail regarding giant caterpillars. An arborist participating in the Cincinnati BYGLive! showed the group two dead mature CECROPIA MOTH (Hyalophora cecropia) caterpillars. There had been several caterpillars on a purple sand cherry in the landscape of a convenience store. The arborist noted they were causing no apparent damage. However, the caterpillars somehow offended the store owner who had them sprayed. The dead were collected by the arborist during a visit to the caterpillar-inconvenient store.
Cecropia moths belong to the family Saturniidae. Larvae of moths in this family are commonly referred to as "giant silkworm" caterpillars. Other notable members of this moth family include; LUNA (Actias luna); POLYPHEMUS (Antheraea polyphemus); PROMETHIA (Callosamia promethean); and the impressively named HICKORY HORNED DEVIL (Citheronia regalis).
These moths have several things in common. First, despite impressively large sizes (4 - 5" long), their caterpillars cause little damage to plants. Most are solitary feeders, and they are not considered serious plant pests. Second, the caterpillars become some of our most impressive moths, adding beauty to our landscapes. Finally, for reasons not entirely known, populations of these moths have been tumbling over the past few decades. Reducing already depleted populations through misinformed insecticide applications robs us of these beautiful moths. Indeed, while a digital version of a luna moth graces a current sleep-aide commercial, the real thing now rarely graces Ohio evenings.

ANOTHER "GREAT" DIGGER WASP
In the last issue of BYGL (August 3, 2006, Issue 18), it was reported that the CICADA KILLER WASPS (Sphecius speciosus) were causing concern around many golf course sand traps and sand volleyball courts. This week, another large solitary digging wasp is stirring concerns, the GREAT GOLDEN DIGGER WASP (Sphex ichneumoneus). The adult great golden digger wasp is about 1"-1 1/4" long. The head and thorax are black and covered with golden-yellow hairs, hence its common name. The back half of the abdomen is also black. The wings are brownish, with the legs and front half of the abdomen reddish-orange.
Even though these wasps are solitary, there may be several females working independent nests in a small area with a soil type favored by the females, and several males may be "patrolling" in the vicinity. The females often start their burrows in crevices between the stones in pathways or in sidewalk cracks. Gravel or sand pathways are also a favored location. Female wasps dig nearly vertical burrows, with individual larval cells branching off horizontally. They provision them with live but paralyzed insects of the order Orthoptera (grasshoppers, crickets, and katydids), then lay a single egg beside the prey. The paralyzed insects remain alive and therefore are "fresh meat" for the newly hatched larvae to consume.
Usually it is not necessary to control these digging wasps unless their presence is a major nuisance. Many insecticides are labeled for wasp control. One can apply a dust formulation of an insecticide such as carbaryl (e.g. Sevin) around and into each nest entrance to reduce numbers of wasps in specific locations.

THE BAGWORM SAGA CONTINUES
Although many of you may be getting tired of hearing about the bagworm (Thyridopteryx ephemeraeformis), the activities of this insect continue to astound BYGLers and we feel compelled to report on it again. Much of the emphasis in past reports about the bagworm have focused on their impacts to evergreen trees and shrubs. This week, the report focuses on the bagworm's impact on deciduous trees and shrubs and its apparent range expansion.
Curtis Young in Lima, Ohio reported observing several species of deciduous trees showing severe defoliation by bagworms. These trees included: honeylocust (Gleditsia triacanthos), bald cypress (Taxodium distichum), London plane tree (Platanus hybrida), and an unidentified species that had no foliage left to identify. All of these trees stood out in the landscape because of the lack of foliage on their branches.
Upon closer inspection of the trees, Curtis found bagworms hanging in midair from silken threads, hundreds of bagworms on the ground, bagworms climbing up the trunks and frass (excrement) all over the ground beneath the trees. Some of the bagworms had discovered neighboring trees and were ascending their trunks as well including ash (Fraxinus sp.) and 'Crimson King' Norway maple (Acer platanoides). The main injury to deciduous trees is a loss of attractiveness; however, one should keep in mind that the populations of bagworms living on these trees could spread to more susceptible trees such as the evergreens.
Distribution of the bagworm appears to be expanding. Amy Stone in Toledo, Ohio is also reporting large populations of bagworm on a number of trees as well as receiving numerous calls from homeowners who are unfamiliar with the insect. Both Dave Shetlar and Joe Boggs mentioned that it was not that many years ago that bagworm was not very common north of I-70. When either of these two entomologists included bagworm in their presentations in the northern part of Ohio, no one knew what they were talking about. This has changed dramatically. Reports of large bagworm populations are now common place in many northern Ohio counties. We BYGLers are interested in knowing what you might be seeing in northern Ohio and southern Michigan. How far north are the bagworms? Let us know by e-mailing Curtis Young at: young.2@osu.edu.

SWARMS OF GROUND BEETLES
Curtis Young and Barb Bloetscher reported receiving calls about hordes (1000's) of beetles swarming to security lights in the country. The beetles have only been identified as a species of ground beetle (Family: Carabidae). The beetles are dark brown to black in body color with tan to yellow legs.
Callers had two complaints: 1) the shear number of beetles was discomforting; and 2) many of the beetles were finding their way inside of structures through cracks under doors and through cracks in foundations. We currently have no explanation for the large numbers that are present. However, ground beetles are predators and a possible explanation as to why they were coming to the security lights is that they were coming for a free meal. Joe Boggs reported that he too had seen the ground beetles at his porch lights, although not in as great of numbers as reported above, and the ground beetles were capturing everything that landed close to them from the many other insects that had been attracted to the lights.

WINDSHIELD WIPES
Joe Boggs reported that early season FOREST TENT CATERPILLAR (Malacosoma disstria) damage remains very evident on oaks and maples where caterpillar populations were high in southwest Ohio. Canopies of trees that had not been stimulated to produce new leaves after suffering heavy defoliation now appear thin, and have been described as "see-through." A close examination reveals that most leaves have pieces missing. However, it is speculated that the damage is mostly aesthetic and does not present a serious challenge to the overall health of the affected trees.

DISEASE DIGEST

CUKE GROWERS IN A REAL PICKLE
Erik Draper reported vegetable growers in Northeast Ohio have been inundated by DOWNY MILDEW on cucumbers and muskmelons. This important foliar fungus (Pseudoperonospora cubensis) only infects members of the Curucbitaceae family like cucumbers, melons, squash, and pumpkins. This disease is particularly obnoxious due to the rapid rates of infection followed by leaf death. The rapid loss of leaves exposes the fruit to excessive sun, which rapidly overheats any immature fruit, resulting in sunscald and reduced fruit quality.
On cucumbers, downy mildew is easily identified by the appearance of yellow and green checkerboarding on older leaves. The leaf infections cause a rapid chlorosis of areas seemingly restricted by leaf veins, resulting in angular lesions that are sharply defined. At first, just the leaf blade dies and turns brown while the remaining leaf petiole and the vine remain untouched and green. Eventually, the entire plant collapses due to the rapid loss of the leaves. In moist, humid conditions, on the underside of yellow leaf infections, there may appear a fungal layer that is white to purplish to almost black in color.
On muskmelons, downy mildew is much harder to identify initially, but the end result of total leaf loss remains the same. Leaf infections appear as mottled, yellow spots on top of the leaf, while on the underside, leaf infections appear as watersoaked areas.
Unfortunately, when downy mildew symptoms become readily apparent on the plants, it is usually too late to do anything about this disease. However, if symptoms are caught early, by using specific fungicides, it is possible to hold off the plant's demise long enough to get the crop picked. If infection has already occurred, the strobilurin and phenylamide fungicides may provide some relief. Useful protectant fungicides consist of chloronitriles and dithiocarbamates. As always, one of the better ways to manage this deadly foliar disease is to select and plant cultivars with genetic resistance to downy mildew.

MILDEW ON 'MATERS MATTERS
Erik Draper reported seeing POWDERY MILDEW on tomato plants in a high tunnel planting that just made him marvel about diseases. High tunnel plantings are essentially inflatable poly houses, or hoop huts, with roll up sides for ventilation and the crop is planted directly into the ground. In previous years, the biggest disease threat within that environment tended to be Botrytis, or grey mold. This year however, the powdery mildew fungus, Oidium neolycopersici took over one of the high tunnels operations and infected every plant in the planting. Interesting enough, tomatoes are rarely affected by powdery mildew when planted outdoors in Ohio.
Powdery mildew symptoms first appear as light green to bright yellow spots on the upper surface of the leaf. These lesions are indistinct and progressively become more noticeable as they develop into the typical white, powdery spots. However, it seems this disease differs from most other common powdery mildews because it is apparently much more aggressive than other mildews. For example, once tomato leaves are infected, they quickly turn brown and shrivel on the plant. This rapid death of infected leaves and defoliation of plants is not typical of most mildews. The fungus spreads easily to nearby leaves or plants by the numerous spores produced, which are easily moved in air currents.
The conditions that favor disease development consist of relative humidity levels greater than 50% (optimum RH >90%) and temperatures ranging from 50-95F. The tomato powdery mildew fungus has a very broad host range, which includes rosemary, pepper, eggplant, and many other bedding plants. This fungus can also survive within certain weed hosts to re-emerge and infect tomatoes the following year, so rotate those garden crops to new spots.

MOIST CHAMBER
* POWDERY MILDEW OF CALLERY PEAR. This disease is not something typically noted in Ohio landscapes, but was noted by Jim Chatfield the past several weeks both in the Cincinnati area in southern Ohio, and in Wadsworth in northeast Ohio. In addition to white mildew colonies on leaf undersides, on petioles and on the stems of twigs, the disease results in yellowish blotches on upper leaf surfaces and some leaf distortion, though damage is not severe.
* DIPLODIA or SPHAEROPSIS TIP BLIGHT OF PINE is a common problem, but often symptoms for the new season's infections do not become fully evident until mid-summer. The PPDC is now receiving samples with needle stunting and browning due to this year's spring infections.
* The high relative humidity and frequent rains very common to northeast Ohio's Geauga County are prime environmental conditions conducive to DOWNY MILDEW OF CRANBERRYBUSH VIBURNUM. Sure enough, Erik Draper is now finding this disease on these viburnums in Geauga County, resulting in downy grayish-white patches of the fungus on leaf undersides and scorched angular lesions due to the infections on the upper surface of leaves.
* Joe Boggs in Cincinnati reported GUGNARDIA LEAF BLOTCH of Aesculus from their BYGLive! program this week. There was severe leaf blotching and reddening on horsechestnuts and horsechestnut hybrids, but only a few lesions on yellow buckeye. As noted in previous BYGLs, the development of evaluation trials of buckeyes and horsechestnuts in Ohio is long overdue. Planning for an "Aescularium" or two is in the works.
* Other diseases reported or noted this past week included confirmed cases of Phytophthora root rot on a number of samples sent to the PPDC (yew, juniper, holly, rhododendron, lilac), anthracnose on lily-of-the-valley, and Septoria leaf spot on a number of plants including sweet woodruff and shrub dogwoods. A creeping myrtle sample had both Phoma dieback/leaf spot and Thielaviopsis black root rot. Black root rot is a considerable problem for many plants in the landscape, especially petunia. We do not have adequate chemical controls for black root rots in most landscape cases, though crop rotations sometimes are recommended for certain plantings. For example: Black root rot problems on your creeping myrtle groundcover? Try a non-host such as ornamental grasses.

TURF TIPS
|
HOW HOT WAS IT?
Dr. Karl Danneberger (OSU, HCS) wrote an article for his SK Turf Notes regarding the heat suffered these last few weeks, and how it affected the turfgrass. To understand the heat faced by turfgrass, his team took canopy temperatures of different species of turfgrass and various surfaces. One day, the ambient air temperature was roughly 95 to 96 degrees F. Well-watered Kentucky bluegrass athletic field turf measured 101 degrees F with the canopy temperature almost 10 degrees F warmer, if the slight breeze was discounted. The artificial surface produced with crumb rubber measured 144 degrees F.
They also measured the temperature before and after mowing. Interestingly, although not statistically different, the canopy temperature declined up to 5 degrees immediately following cutting. His theory is that the cut blades released moisture which cooled the air around the turfgrass however, the decrease in temperature was observed for less than an hour, then rose in the afternoon. Moisture stressed turfgrass would most likely show an increase in temperature directly after mowing. For this reason, he recommends syringing the turfgrass after mowing, if it appears droughty. If possible, however, mowing should be delayed until the evening, when the sun is less intense, and the turfgrass under less stress.
Finally, soil temperatures were taken at three different depths in two days. The temperatures for both August 1st and 2nd were 78 degrees F at 3, 6 and 12 cm at 8:30 a.m., then the surface temperature rose to 92 degrees F by 2:00 p.m. The soil temperature 12 cm. deep increased proportionately with the surface temperature to reach 92 degrees F as well. "Needless to say, these... soil temperatures are not conducive for root growth", wrote Karl.

CHECK OUT THE ANNUAL PLANT TRIALS AT THE CINCINNATI ZOO & BOTANICAL GARDEN
Want to see some beautiful gardens, and perhaps treat your family to some great entertainment at the same time? Now is the time to take a tour of the Cincinnati Zoo and Botanical Garden (CZBG). Notice the splendor provided by the bright colors of 150 varieties of annuals in gardens just about everywhere you go. There are mass plantings and many, many individual containers. Also notice that all plants are nicely labeled. Take a notepad . . . and a camera. Use the camera to record the outstanding plant combinations that Steve Foltz, Director of Horticulture, and his staff, always come up with.
Aside from their ascetic beauty these gardens are also annual plant trials that are a cooperative effort of the CZBG, the Cincinnati Flower Growers Association (CFGA), and the OSU Extension, Hamilton County. This is the 5 th year for these trials. As in past years, the trials are being conducted with three goals.
The first is to evaluate herbaceous annuals on the basis of quality and performance throughout the growing season in order to determine which should be recommended for planting in area gardens. Conditions encountered in the "average" or "normal" garden in the area are replicated as closely as possible. The soil, mostly a heavy clay, is amended only with some softwood pine fines. Fertilization consists of an irregular schedule of water soluble fertilizer applications (a few a month initially, which taper off through the rest of the growing season) from an injector and tank on a trailer. Most beds are irrigated with spray stakes. No pesticides are used.
The second goal is to provide the general public and commercial growers and landscapers an opportunity to observe many varieties of the latest, yet fairly well-proven, annuals available that were professionally grown in attractive garden settings (including in planters).
The third goal is to promote those annuals that performed well enough to be recommended for planting in area gardens. Only those that perform well throughout the growing season are recommended. Most that pass the test are generally planted for several years to see how well they respond to a variety of environmental conditions over time.
Plants for this year's trials have been provided by: Pan American Seed Co., Sakata, Proven Winners, 4-Star Greenhouse, Raker's, and members of the Cincinnati Flower Growers Association. Three interns were hired to plant plugs and grow and maintain the plants in greenhouses and the landscape. What a great education they are getting!
The results of these trials are published by the zoo every year in very nice pamphlets. The pamphlets are available at the Botanical Center at the zoo. They are also available online at www.cincyzoo.org/Exhibits/GardenBest/Gradens.html and the links below.

OCTOBER 11 TREE FORUM
The "Why Trees Matter" Community Tree Forum, featuring the "Environmental, Economic and Social Benefits and Impacts of Community Forests" will be held on October 11 at OSU's OARDC in Wooster. This forum is a program of the OSU Next STEP (Street Tree Evaluation Program), OSU's Secrest Arboretum, and the OSU Extension Center at Wooster. "Why Trees Matter" is for all those interested in Ohio's community forests, including street tree commissions, mayors, arborists and urban foresters, utility companies, economic development and resource managers, nurserymen and landscapers, and all citizens of Ohio interested in the resource of trees in our urban and suburban areas.
The keynote address will be by Dr. David V. Bloniarz, the project coordinator of the USDA Forest Service's Northeast Center for Urban and Community Forestry at the University of Massachusetts/Amherst. Dr. Bloniarz has worked on numerous urban forestry projects throughout the northeast U.S., including volunteer street inventories in communities of various sizes in Massachusetts and in New York City. He is a key scientist in developing models and software for determining values of streetscape trees, developing volunteer-driven inventories of urban forests, and in community and natural resource management in community forests. Dr. Bloniarz will address "Why Trees Matter" in terms of current and emerging research of environmental, social and economic benefits of trees.
Additional programs at the Forum will include the current and future Street Tree Evaluation Program of OSU partnering with the Ohio Department of Natural Resources Division of Forestry and the development of the new OSU Community Tree research plots at Secrest Arboretum and in communities throughout Ohio. For further information and registration materials for October 11, contact Sue Beasley at the OSU Extension Center at Wooster Beasley.37@osu.edu , 330-263-3799, fax = 330-263-3667, 1680 Madison Avenue, Wooster, OH 44691).
