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 http://onla.org .
*PERENNIAL PLANT OF THE WEEK. BLANKET FLOWER (Gaillardia x grandiflora) Yes, the chrysanthemums and asters are in their glory right now, but do not forget some of the summer favorites to give you great fall flower power. Gaillardia x grandiflora, a member of the drought-tolerant sunflower family (Asteracea), is native to North America. Blanket flowers do best when grown in full sun, light, well drained soil, and are relatively trouble-free. Hardy in zones 2-10, blanket flower forms a dense mound growing 8" - 2' tall. It has bright daisy-like single or bi-color blooms ranging from yellow to red or orange. Reaching from 2 - 4"across the blooms may be single or double flowers. The long blooming season of blanket flowers, (through early frosts), make this plant our choice for perennial plant of the week.
Some of the popular cultivars include:
*WOODY PLANT OF THE WEEK. SEVEN-SON TREE, Heptacodium miconoides is a very attractive large shrub or small tree during late summer through fall. This plant has an attractive, fragrant, cream colored, cluster of blossoms in late summer which are succeeded by clusters of showy, purple fruit. The calyx on all the fruit of this plant is unique, purple, and showy as well. Expect this plant to survive in any part of Ohio with moderate care. It will grow to 20' in height and spread half that distance if planted in full sun and drained soils. The fall color of H. miconoides is a bright purple with bronze over-tones. As the foliage falls away the Seven-Son tree shows off even more by revealing an impressive exfoliating bark.
*ANNUAL PLANT OF THE WEEK. IMPATIENS (Impatiens walleriana). Whether you call them balsams, poor man's orchid or just plain Impatiens, cultivars of this species of annual seem to perform without fail. If the shady garden calls for ankle high color, the many cultivars of Impatiens walleriana offer every color imaginable and ask for minimal care in return. The annual plant trials at the Cincinnati Zoo & Botanical Garden has historically sought to select cultivars for their merit- not species. With this species, however, the need for an exception gradually became obvious when the sheer number of exceptional cultivars sharing the parentage of I. walleriana was considered. Some of the notable series that have been trialed at the Zoo and Botanical Garden are 'Accent', 'Super Elfin', 'Salsa mix', 'Fanciful', and 'Cajun'. All of these series have all been outstanding. The size, color and single vs. double flowers seem to be the only questions for the decision of which plant variety you will choose for the flower beds. Therefore, like several of our annual of the week selections, this annual was a top pick at the Cincinnati Zoo and Botanical Garden.

THE WEEKLY WEED
DEERTONGUE or deertongue panic grass, (Panicum clandestinum.) - Recently, a Lucas county client brought in an aggressive grass growing along the roadside and creeping into his property and was looking to Extension for identification and control options. After taking the weed to Farm Science Review for expert identification, Jeff Stachler, an OSU Extension Program Specialist for Weed Science identified the hairy grass as deertongue or Panicum clandestinum. This perennial grass has long creeping rhizomes making a dense patch of grass.
Since most Panicum species are warm-season grasses, control strategies should be considered soon. As a perennial grass, glyphosate would be the most effective herbicide. However, glyphosate is a non-selective herbicide. Jeff's recommendation was an application rate of at least 1.5 lb active ingredient per acre of glyphosate. He suggested that the client add, ammonium sulfate, (AMS) to the mix at 17 lb/100 gallon of spray mixture. He cautioned that glyphosate needs to be applied before a frost, which means the application should be applied soon and that the minimum height of the grass should be 10" to achieve maximum control in a single application.

BEWARE OF POISON IVY!
POISON IVY (Rhus radicans), Many BYGLers have received phone calls about poison ivy. Poison ivy is showing brilliant, yellow, orange and red fall color. Many folks hike in the woods to enjoy this great fall weather. Unfortunately, a contact with poison ivy can ruin that experience for many.
The best way to identify poison ivy R radicans is by its characteristic compound leaf consisting of three leaflets. The leaflets are two to four inches long, dull or glossy green with pointed tips. The middle leaflet is generally larger than the two laterals. The margins of the leaflets are variable, appearing irregularly toothed, lobed, or smooth. The leaves are positioned alternately on the stems. In contrast, VIRGINIA CREEPER Parthenocissus qinquefolia, a non-poisonous vine often mistaken for poison ivy, has five leaflets radiating from one point of attachment.
The blistering rash caused by poison ivy is the direct result of contact with the oily toxicant, known as urushiol. It is found in resin ducts within the plant's phloem. These ducts are found throughout the plant, including the roots, stems, bark, leaflets and certain flower parts. The plant has to be crushed, broken, or in some way injured to release the resin. The injury may be something as little as an insect chewing on the plant.
Once urushiol is released, it can find its way to your skin by direct contact with the plant and then spread by touching other parts of the body. Because the sticky, oily substance is easily transmitted, there are indirect ways to contact it, for instance, from the fur of the family pet, garden tools, garden gloves, clothing, golf balls or other objects that have come in contact with an injured plant. Contrary to popular belief, the rash from poison ivy cannot be transmitted from touching the oozing blisters.
If you know you have contacted poison ivy, wash the area as soon as possible with soap and cool water. Warm water may cause the resin to penetrate the skin faster. Because urushiol can penetrate in a matter of minutes, you may still get a rash, but have minimized the infected area. A visible reaction, redness and swelling may be apparent within 12 to 24 hours. Contact your family physician or pharmacist for recommendations for effective non-prescription medication.

ONE PERSON'S WEED
One person's weed is another person's flower. That sums up the weed observations of BYGL callers this week. Fencerows and fields are full of color from the more ornamental weeds that were left to grow this season. The majority of the fall color is provided by plants in the Composite or Aster family (Asteraceae).
WHITE HEATH ASTER (Aster pilosus) grows as clumps of erect semi-woody stems 3' - 4' tall. Leaves and stems of this perennial are hairy. Later in the season, the leaves are often absent on the lower portion of the stems. The small white flowers are produced in such large numbers they often weigh the plant down, pulling the stems to the ground.
Before flowering, the NEW ENGLAND ASTER (Aster nova-angliae) is similar in appearance to the white heath aster. Leaves and stems are covered in hairs and it grows in clumps. However, flowers are purple and not as numerous. The lower portion of the stem tends to retain older dead leaves and the overall height is less than the white heath aster.
The last composite making a show this fall is CANADA GOLDENROD (Solidago canadensis). Their numerous yellow flowers are born on drooping panicles. This clump-forming perennial can reach heights of 3' - 4'.
Representing the Pokeweed family (Phytolaccaceae) is COMMON POKEWEED (Phytolacca americana). This showy weed is huge, reaching heights of 4' or more. It resprouts from a perennial rootstock every spring. Large succulent leaves and stems are tinged with red or purple. It grows so large and fast it is often misidentified as a small tree. At this time of year, the plant is quite ornamental, festooned with red stems and racemes of dark purple berries. The berries are eaten by birds, and though attractive, be warned that every part of this plant is toxic.
What makes such showy plants a weed is determined by the grower. Cultivated forms of these common weeds are in the garden centers and being grown in perennial gardens. A similar species planted by a bird, a few feet away in a fencerow might very well be considered a weed. It just depends on what side of the fence you are on.

PRE-FROST CHECKLIST
The cooler evening low temperatures are reminding us that autumn is here. With the arrival of fall we can count on two things occurring in our outdoor environments, shorter days and an eventual hard freeze. According to the OSU Extension Bulletin 672, The Ohio Vegetable Production Guide; Ohio ranges from an average high of 200 growing days without a killing frost along Lake Erie's shoreline to as few as 140 growing days around the Mahoning Valley in East-Northeast Ohio. Average hard frost damage generally occurs around Ohio during the month of October. Keeping this in perspective, Dave Goerig and fellow BYGL'ers have assembled this "Pre Frost Checklist" of some of the late season tasks to perform soon if you haven't managed them already. Can you think of other fall chores we may have missed? Email them to goerig.1@osu.edu to be included in future BYGL articles.

GIANT "MUTANT MOSQUITOES" REAPPEAR
CRANE FLIES (Tipula spp.) Several BYGLers reported that crane flies are beginning to cruise lawns in several areas of Ohio. Crane flies look like giant, mutant mosquitoes, and they can startle homeowners when they venture indoors. Fortunately, they do not possess mosquito-like piercing-sucking mouthparts, so they do not bite. However, clouds of crane flies billowing above lawns can be a real nuisance.
Adults usually appear in Ohio landscapes during two peak periods. Some species produce a heavy adult emergence in the spring while other species generate adults in the fall. The larvae of most species feed on decaying organic matter in the soil, and they especially appreciate areas that are continuously moist. For this reason, the heaviest populations appear to be relegated to the parts of the state that experienced heavy rainfall earlier in the season. Indeed, Joe Boggs noted that these gangly insects are a rare sight in the droughty southwestern part of the state.
Larvae of crane flies that feed beneath turfgrass are called "leatherjackets" because of their tough, leathery exoskeleton. Like the adults, these legless maggots occasionally appear en masse spilling onto driveways or sidewalks. Such a dramatic appearance may signal that the lawn has a thatch problem since the larvae are particularly fond of decaying thatch. However, the species found in Ohio cause no damage to the turfgrass.
The same cannot be said for two non-native species that have been found in the northeastern states and eastern Canada. Both were accidentally introduced from Europe. Larvae of the EUROPEAN CRANE FLY (Tipula paludosa), and the MARSH CRANE FLY (T. oleraceae) feed on the crowns and blades of living grass plants. Both can cause serious damage to turfgrass. Fortunately, these species have not yet been found in Ohio.

GRASSHOPPER HORROR SHOW
Joe Boggs reported recently finding large numbers of grasshopper cadavers in various stages of disintegration clinging to goldenrod stems. The macabre scene was the work of a fungal grasshopper pathogen, Entomophaga grylli. Earlier this season, we reported that grasshopper populations have been high in the drought stricken southwestern part of the state. The fungal infection was probably inevitable given the large numbers of grasshoppers rubbing tarsi.
E. grylli is actually a fungal species complex that has at least two distinct pathogens in North America: E. macleodii and E. calopteni. These fungi are common in the Western U.S. and Canada where they are very important agents in managing grasshoppers in crops and rangelands. Infected grasshoppers crawl to the tops of plants and die with their heads pointing upward and their legs wrapped tightly around the stalks of the plants. The disease is commonly called "summit disease" because of the grasshopper's weed-climbing behavior.
The cadavers remain attached to the plants for several days until their bodies, having been digested and consumed by the pathogen, dry out and fall apart. As the grasshopper disintegrates, millions of resting spores are released into the environment. These spores fall to the ground were they remain on or under the soil. When these spores germinate, in the current or following year, they produce sticky spores that are ejected into the surrounding area to adhere to the exoskeleton of unsuspecting foraging grasshoppers. The spores then germinate and penetrate the body of the new host, and the bizarre effects of the fungal infection repeats.
Summit disease is capable of causing high mortality in grasshopper populations. Unfortunately, epizootics (outbreaks) are usually sporadic and localized. Heavy infections generally occur late in the season after the heaviest grasshopper feeding damage has occurred. Indeed, Joe noted that there appeared to be plenty of new fungal hosts that were continuing to hop about.

DISEASE DIGEST

FISHING FOR PHYTOPHTHORA
John Hartman (University of Kentucky, Plant Pathology) provided participants at the 10th Annual Buckeye-Bluegrass BYGLive! with a description of a fascinating new method to detect Phytophthora ramorum, the fungal-like pathogen responsible for Sudden Oak Death (SOD). John stressed to the group that SOD has not yet been found in Kentucky. His report was answered with a collective sigh of relief from the group.
However, John noted that past methods used to detect this potentially devastating disease placed a strong emphasis upon the "yet" regarding SOD since they relied heavily upon finding infected plants. This approach is fraught with a number of challenges, including geographical coverage. The chances of happening upon an infected plant in the forests of Kentucky would be statistically equivalent to winning the Lottery; however, a Phytophthora find would not be a win.
The method John described relies upon exploiting the strong association that Phytophthora have with water. Indeed, the microorganisms in the genus are sometimes referred to as water molds because they can be found free-living in water. Of equal importance, the Phytophthora in the water will infect leaves, and rhododendron is highly susceptible to these pathogens. Plant pathologists simply cage rhododendron leaves in nylon mesh bags, and allow them to remain immersed in streams for one week. They then collect the leaves and identify the Phytophthora species that have taken the "bait."
John noted that this method of "fishing for Phytophthora" has yielded highly accurate results in California and Oregon. He indicated that by placing cages in streams, and moving upstream from points of detection, Phytophthora hunters have been able to discover individual infected plants by zeroing in on locations between "positive" and "negative" stream detections. The method has had a significant impact on learning the extent of spread of the disease. In a discussion with Dave Dyke, John indicated the method may be applied to detecting other forms of Phytophthora in irrigation ponds, including those that can infect greenhouse crops.

DISTILLERY BLACK MOLD: A DIAGNOSTIC CHALLENGE
The 10th Annual Buckeye-Bluegrass BYGLive! was held Monday at the historic Buffalo Trace Distillery in Frankfort, KY., the oldest continually operating distillery in the U.S. The Distillery is best known for its production of bourbon whiskey, a unique American product. Participants learned far more from our guide, Freddie Johnson, a third generation employee, than can be summarized in the BYGL.
However, here are a few factoids that led to an interesting plant diagnostic challenge. Bourbon whiskey must be aged in charred white oak barrels, and no additives are allowed including flavors and colorants. The barrels are housed in unheated aging warehouses for years. All of the color and most of the flavors arise during aging from the ambient temperature-driven interactions between the charred oak and the whiskey. In fact, 60 - 70% of the identified flavors are oak-based. Consequently, the group learned that the industry is pursuing several lines of research to illuminate the exact effects that white oak has on bourbon flavors. Indeed, there was a hint that breeding programs may be underway to produce the "perfect" tree.
The 110 acre distillery has 49,000 barrels of bourbon whiskey aging in warehouses located throughout the property. During the aging process, as much as 50% of the whiskey may be lost to evaporation, depending upon length of aging. The loss is called the "angel's share." The alcoholic-rich vapor supports a unique phenomenon associated with distilleries: the rampant growth of black sooty molds. The growth has many names including distillery black mold, angels breathe, and Torula mold; based on the genus of one of fungi identified in Europe as being associated with the growth.
The sooty mold growth was very evident at the Buffalo Trace Distillery on the outside walls around the windows of the barrel warehouses. It looked like a fire had taken place in the warehouses. The black mold also covered the tops of outside pipes, the roofs of buildings, and it coated the stems of landscape plants. The mold on the landscape plants presented an interesting diagnostic challenge since it strongly resembled black sooty mold associated with plant-sucking insects, such as aphids and scales. Participants marveled at two large rose-of-Sharons with their main stems thoroughly blackened.
Three nearby magnolias also sported stem blackening, as well as black mold growth on the leaves. However, a closer observation revealed the blacking did not arise from alcohol escaping the barrels, but from "honey dew" escaping the back-ends of a soft scale. The scale was tentatively identified as TULIPTREE SCALE (Toumeyella liriodendri) and is well known to be prolific producer of honeydew. Aside from its namesake host, it also infests magnolia as well as lindens. The infestation was heavy, with scale bodies piled on top of one-another. The trees were literally buzzing with wasps, yellowjackets, and flies imbibing on the sugar-rich honeydew.
Participants also observed an interesting mealybug-like creature moving among the scales, which presented another diagnostic challenge given that mealybugs produce honeydew. However, the mealybug look-a-like was the larval stage of a lady beetle. The larvae of several species cover themselves in white, flocculent material, a variant on the saying that "you are what you eat." All-in-all, the distillery black mold, coupled with the sooty mold from the scale, and the mealybug-like lady beetle provided a highly educational lesson in the importance of untangling plant problem look-a-likes.

BYGLIVE! RESEARCH UPDATES
BYGLers Jim Chatfield, Erik Draper, Dave Dyke, Cindy Burskey (Clermont County), and Joe Boggs, along with the rest of the participants in the 10th Annual Buckeye-Bluegrass BYGLive! in Frankfort, KY., were treated to an enlightening research update provided by University of Kentucky researchers and graduate students. It was very evident that a lot is happening at the University of Kentucky! Here is a brief snapshot of results reported and new research being pursued that has not been previously mentioned in this BYGL.
Dan Potter (UK, Entomology) updated the group on research that has been completed on the MAPLE SHOOT BORER (Proteoteras aesculana). Dan reported that they have identified the pheromone and worked-out the biology of this serious Kentucky nursery pest. Previously, it was thought that the insect originated from outside of the state; however, they learned the moth is native to Kentucky. It was also thought that control required making a well-timed insecticide application at the time leaves reached the "mouse-ear" stage. The research on the moth's biology revealed that the application window is in fact open for about a month. Finally, they now know the accumulated Growing Degree Days that signal moth activity which further refines application targets.
Dan also reported on their work with controlling CALICO SCALE (Eulecanium cerasorum). Central Kentucky has experienced serious localized outbreaks of this soft scale resulting in tree stress, decline, and even death. He was glad to report that their research showed that a single spring application of dinotefuran (e.g. Safari) mixed with Pentra-Bark to the main trunk of zelcova trees provided an 85% reduction in scale populations.
Dan then introduced his impressive (as always!) group of graduate students pursing a range of fascinating research. Carl Redmond (Ph.D. candidate) reported that he conducting research to illuminate that white grub complex that is occurring in Kentucky as well as the predators and parasitoids that may be helpful in suppressing grub populations. He has already learned that MASKED CHAFERS account for around 85% of the white grubs found in the state. Andrea Bixby (Ph.D. candidate) is pursuing an NPV (virus) specific to black cutworms to learn whether the virus can provide continual reduction of caterpillar populations with a single inoculation of golf course tees and greens.
Craig Keathley (Ph.D. candidate) reported that he is investigating a classic "unintended consequences." Various tall fescue plant breeding programs around the county are developing cultivars that are more palatable to cattle, and safer for them to eat because they have reduced levels of endophytic fungi. Of course, the reduced endophyte also reduces alkaloids produced by the symbiotic fungi that help protect the plants against top-feeding insects. Craig will investigate whether or not these new tall fescue cultivars are now more susceptible to insect damage. Finally, the newly arrived (within weeks) Sara Mack (M.S. candidate) is planning to investigate the impact ants have on predators and parasitoids of soft scales. It is known that ants will defend aphids in exchange for their honeydew; however, the impact of removing the protectors is not well documented. Of course, Sara was quickly shown the aforementioned soft scale infestation at the distillery!
Amy Bateman, who is just about to complete her M.S. thesis work with John Hartman, provided a very interesting follow-up to her research report she made at last year's Buckeye-Bluegrass BYGLive! Amy has investigated infectivity of the Sphaeropsis formally known as Diplodia tip blight fungus on scotch pine in Christmas tree plantations. She has learned that although pruning tools can pick-up infectious spores, shearing infected plants in July resulted in very little initiation of new infections. The results will have a significant impact on Christmas tree growers.
Finally, Bill Fountain (UK, Horticulture) provided a fascinating look at the range of impacts weather conditions can have on tree health, with a strong look at the effects of the historical drought experienced this season in central Kentucky. BYGLive! participants were keenly interested given that conditions in Cincinnati have mirrored those experienced in Kentucky.
Bill reminded the group that this season's tree disasters actually started in the spring. The April freeze damaged or killed actively growing cambium in trunks and branches of species that had been tricked into growing too early by the unusually warm March weather. The summer drought provided a double-whammy by reducing annual ring growth of the sapwood. The smaller sapwood has reduced the ability for some trees to conduct sufficient water throughout the plant to off-set high water loss through enhanced evapotranspiration caused by high temperatures. As readers can imagine, Bill's final prognoses was not optimistic.

EAB RESEARCH UPDATE, NOVEMBER 7TH
The Ohio State University's Emerald Ash Borer Outreach Team is sponsoring an all day program, Emerald Ash Borer Research Update - What We Know and What We Need to Learn. It will be held from 9:00 am - 3:30 pm at All Occasions Catering, 6869 Waldo-Delaware Road in Waldo, OH. The registration deadline is Friday, November 2nd. Registration materials and program information is available on the ashalert website at http://ashalsert.osu.edu or by contacting the OSU Extension at Toledo Botanical Garden at 419-578-6783.
When the emerald ash borer (EAB) was discovered in North America nearly 5 1/2 years ago, it did not take long for many to realize that there was a lot to learn about this tree killing wood borer. The challenge of the lack of the knowledge quickly became an opportunity to learn through research. Join is to find out what has been learned about EAB through research. From insect biology to insecticide trials, researchers will share their findings. We are excited to have such an outstanding group of presenters able to share their day with us. Presenters include: Joe Boggs/OSU; Deb McCullough/MSU; Therese Poland/USFS; AnneMarie Smith/ODNR; Davis Sydnor/OSU; Kamal JK Gandhi/OARDC; and Dan Herms/OSU and OARDC.
