PLANTS OF THE WEEK - July 17, 2008Read all about perennials and landscape trees and shrubs in the ONLA publications "Perennial Plantsfor Ohio" and "Landscape Plants for Ohio." The descriptions and photographs of plants were providedfor these publications by the OSU ENLT Team along with other industry plant lovers. These full-colorpublications 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 ].

*WOODY PLANT OF THE WEEK. TUPELO or BLACK GUM - (Nyssa sylvatica). The tupelo or blackgum is a large tree reaching heights up to 50', and is an excellent specimen tree because of itsconsistent fall color. It grows best in a moist, well drained, acidic soil with a pH between 5.5 to 6.5. The

tree however, is very tolerant of less than desirable growing conditions, and is hardy to zone 3. The habit is somewhat pyramidal whenyoung, and seems to mature into an upright-oval look. The foliage is dark green during the summer; changing to a very showy brightorange to scarlet color in autumn. The tree produces a bluish black drupe type fruit about 1/2" long, that is attractive to birds. Although thetree is difficult to transplant because of an extensive taproot, the industry does have several growers that are successfully producing thistree.

*PERENNIAL OF THE WEEK. GAILLARDIA or BLANKETFLOWER - (Galardia xgrandiflora.). This genus of perennials is anothergroup where extensive breeding has brought them back into popularity in recent years. Plants tend to grow around 3-4' tall with about a 2'spread. They begin to bloom in July and last well into August and longer if deadheaded. They are a great full sun plant, but must havegood drainage as they won't survive in wet winter clay soils. The daisy-shaped flower colors are red, yellow, burgundy, and a blend; someof the newer cultivars have bright orange flowers. One of the most interesting recent introduction is 'Fanfare' with orange and yellow flutedflowers; it grows 12-14" tall. 'Summer's Kiss' with salmon, apricot, gold, and yellow flowers growing 18" tall and 'Tokavar' with brick redflowers on 18" plants are both newer cultivars that also make great cut flowers. Some varieties only last 2-4 years in a typicalgarden.Photo: cd0011-229

*ANNUAL OF THE WEEK. CLEOME or SPIDER FLOWER - (Cleome spp.). Large flowers bloom prolifically atop long stems on thiswell-known annual. Known as the spider flower because of the "spidery-like" flowers, the cleome is an excellent plant for cottage orVictorian gardens or fillers in the perennial bed or in large containers. Many cultivars of this plant are started by simply scattering seed in



the garden. Many will also continue to self-seed throughout the years. Plants grow to around 3-4' tall and about 1-2' wide. Flower colorsare usually pink, lavender, and white depending upon the variety, and the blooms continue all summer without deadheading. Numerouscultivars have been recently introduced to compliment the old-fashioned varieties. 'Sparkler' flowers grow atop 4' stems and are greatwhen used in the middle of a pot of petunias (looking like a sparkler shooting out of the container!). One cultivar that has caught a lot ofattention lately is 'Senoria Rosalita'. The plant is a bit more compact than most and grows to around 2-3' tall with purple flowers on topthat last from the early season until frost. The best feature, however, is that the foliage remains on the plant all season whereas manyother varieties have bare legs with blooms on top.

TOXIC TREE TROUBLESThe Mahoning County Extension plant pest clinic is operated by the Mahoning Master Gardener Volunteers. These dedicateddiagnosticians take their service to the office seriously. Occasionally, samples of plant problems come into the office that perplexes thisseasoned group, as was the case last week. Dave Goerig noted reviewing a bag full of wilted vegetable plants, with roots attached thatemitted a slight nutty odor. It turns out the vegetable gardeners who brought in the sample unfortunately located their new garden close toa black walnut tree.

The roots of BLACK WALNUT (Juglans nigra) and BUTTERNUT (Juglans cinerea) produce a substance known as JUGLONE(5-hydroxyl-alphanapthaquinone). Many plants such as tomato, potato, blackberry, blueberry, azalea, mountain laurel, and rhododendronmay be injured or killed if planted within the rootzone of one of these trees. The toxic zone from a mature tree occurs on average in a 50'to 60' radius. Not all plants are sensitive to juglone. For a partial list of plants that show resistance to this toxic tree, review OSU ExtensionFactsheet HYG-1148, "Black Walnut Toxicity to Plants, Humans and Horses."


OSU Fact Sheet

HUMMERS THAT AREN'T BIRDSOnce again, BYGLers are receiving calls about hovering critters that look and act like humming birds, but are a little too small to really bea bird. Many callers describe the animal very well because they are flying during the day and thus are quite visible; and the callers alsosuspect that it is an insect, but just can't believe that it really is an insect. What they are observing are moths belonging to theLepidopterous family, Sphingidae. Moths in this family are referred to as sphinx or hawk moths. Most of the moths in this family arenighttime fliers, but a few are daytime fliers and are referred to as the HUMMINGBIRD MOTHS (Hemaris spp.). Three species ofhummingbird moths can be found in Ohio, the most common of which are the HUMMINGBIRD CLEARWING (Hemaris thysbe) and theSNOWBERRY CLEARWING (H. diffinis). The most seldom seen is the SLENDER CLEARWING (H. gracilis).

The hummingbird clearwing has a greenish body and a dark reddish-brown band near the back of the body. Its wing-span is nearly 2",and the wings are almost devoid of scales, thus the clearwing common name. The snowberry clearwing is yellow and black striped like abumblebee with a wingspan of 1- 2". The least common species is the slender clearwing moth, which is slightly smaller than thehummingbird clearwing. This moth also has a more yellow body and a gold ring between the yellow portion and the dark band near theabdomen. A distinction that needs to be made at this point is that although they are called clearwings, they are not the clearwings thatproduce larvae that are destructive borers such as the banded ash clearwing moth which belong to the Lepidopterous family, Sesiidae.

The caterpillar of the hummingbird moths are leaf feeders and are called hornworms. They commonly feed on are honeysuckles andviburnums. Their feeding may benefit the environment by feeding on the invasive honeysuckles. Perhaps they are helping to depletenoxious species of honeysuckle, growing out of control in many woods, stream edges and fence rows! Photo: cd0006-495.jpeg


Nature Guide FlashButterflies and Moths of North America

ANOTHER WEED ATTACKEDCurtis Young apparently can't stay out of the weeds. This week Curtis reported finding another weed,



GOLDENROD (Solidago virgaurea), being chewed up by insects. The goldenrod plants were exhibitingtwo types of defoliation damage. First, the tops of the plants have numerous holes in the leaves; oncloser examination, several small dark colored beetles were observed in the tops of each plant. Thesecond type of damage was found on the lower leaves of the plants that were brown and shriveled. Thebeetles that were found in the tops of the plants and were responsible for the majority of the damage onthe goldenrod were identified as the GOLDENROD LEAF MINER (Microrhopala vittata). Thus, the lowerdamaged leaves were the result of leaf mining grubs (larvae).

These beetles belong to the family Chrysomelidae: subfamilyCassidinae. This is the same group to which the BASSWOOD LEAF MINER (Baliosus nervosus) andthe LOCUST LEAF MINER (Odontota dorsalis) belong. Both of these beetles can do significant amountsof feeding on their respective hosts, American linden and black locust. At first glance, a defoliator ofgoldenrod doesn't sound bad, but goldenrod is used in perennial beds as an ornamental plant. Thus, aninvasion of this insect in a perennial bed may be an unwelcome guest. <The goldenrod leaf miner beetleis dark brown in color. Some individuals have a reddish-orange stripe down each side of the back(elytra). The adult is about 1/4" in length.


Bug of the Week by Mike Raupp

LACE BUG POTPOURRI

Participants at last week's Plant Diagnostic Academy (PDA) at the OSU/OARDC in Wooster, Ohio,observed the handiwork of a number of lace bugs (Hemiptera: Tingidae) including: HAWTHORN LACEBUG (Corythucha cydoniae); BASSWOOD LACE BUG (Gargaphia tiliae); OAK LACE BUG (C.arcuata); and CHRYSANTHEMUM LACE BUG (C. marmorata).

Lace bugs use their piercing/sucking mouth parts to suck juices from their host plants. Their feedingproduces tiny yellow or whitish leaf spots (stippling) that may coalesce to produce large, yellow-to-copper colored areas on leaves, and early leaf drop. The bugs also deposit unsightly hard, black,varnish-like tar spots of excrement onto the leaf surface as they feed. Most lace bugs have multiplegenerations per season, and their damage builds with each succeeding crop of new bugs.

Hawthorn lace bugs have a cosmopolitan palate and will feast on a variety of plants in the Rosaceaefamily, as well as a few plants outside of this family. They are commonly observed on Cotoneaster sp.and Amelanchier sp., as well as their namesake host. Hawthorn lace bugs are found on the lower leafsurface.

Basswood lace bugs should more accurately be called "Tilia lace bugs" since they may be found onseveral species in the Tilia genus. PDA participants found the lace bugs in their typical lower leafsurface location on littleleaf linden (T. cordata) and silver linden (T. tomentosa). The stippling symptomon the upper leaf surface of silver linden was very unusual in that the spots were confined to distinct1/4" diameter spots. It was speculated that the unusual pattern was produced by nymphs feedingaround egg clusters.

The oak and chrysanthemum lace bugs are unusual in that oak lace bugs live on the upper leafsurface, and the chrysanthemum bugs live on both the upper and lower leaf surfaces. Despite itscommon name, the chrysanthemum bug will feed on several herbaceous perennials, particularlyasters.




OSU Extension Bug Doc Fact SheetNC State Entomology Insect Note

GALLMANIAPDA participants were also "treated" to a wide variety of plants galls produced by a number of insect andmite gall-makers … 'tis the season! Two of the more unusual galls observed by the group were theMOSSY ROSE GALL produced by the wasp Diplolepsis rosae; and the HACKBERRY PETIOLE GALLproduced by the psyllid Pachypsylla venusta.

The round to oblong-shaped hackberry petiole galls are light-green to greenish-yellow and measure 1/2"in diameter. They occur near the base of the leaf blade and leaves may become distorted as they areincorporated into the gall structure. The galls provided a brief lesson regarding gall-terminology. Thepetiole galls are plurilocular, meaning that there are multiple chambersin each gall, as opposed to unilocular which means there is only one

chamber per gall. And, the galls are unilarval, meaning that each chamber houses a single gall-makingpsyllid nymph as opposed to multilarval which means gall chambers house more than one immaturegall-maker.

Mossy rose galls are huge, spherical, hairy-looking structures that arise from year-old rose stems andmeasure as much as 2" in diameter. The galls appear on the stems in June or July. A close examinationwill reveal that the "hairs" are actually tendrils that are covered with short spikes. The tendrils are lightgreen at first, but they quickly become much more colorful with the green becoming deep red accentedby pink overtones. The plurilocular, unilarval galls may house 10-20 wasp larvae.

The rose galls cause little harm to the overall health of rose plants; however, a heavy infestation maydetract from plant aesthetics. Old galls turn an unsightly grayish-brown and can take 1 - 2 years todegrade and disappear. Since the wasp larvae spend the winter in the galls, pruning to remove the gallsin the fall or very early spring provides an effective control by reducing wasp populations in roseplantings.

PEARLEAF BLISTER MITEPearleaf blister mites (Phytoptus pyri) were reported in an earlier BYGL this season when the damagecaused by these microscopic eriophyids was just becoming evident. PDA participants observed holesappearing in necrotic tissue on the underside of ornamental pear leaves meaning that the damage isnow beginning to peak for the season. Feeding by the mites produces small, distinct blisters on theupper leaf surface and rough, irregular patches of necrotic tissue on the lower surface. The blisters arelight-green at first, but later turn pinkish-red, and eventually brownish-black. The blisters may coalescegiving the leaf a blackened, gnarled appearance. The patches on the lower surface turn from dark brownto black and tiny exit holes appear as mites emerge.

The tiny, cigar-shaped blister mites overwinter under bud scales andinitiate blister formation as leaves expand. They first feed on the lower leaf surface, causing theepidermis to rupture. The mites then crawl into the leaf and deposit eggs. As eggs hatch, the new mites



continue feeding within the leaf, destroying more cells. Blister and necrotic patch symptoms becomemost evident after successive generations of mites have fed within the leaves. Although highpopulations of this mite may cause dramatic symptoms, damage is seldom significant relative to treehealth. Control is generally not warranted since high populations on landscape trees seldom occur oversuccessive years.

BUG ID MAKES BOGGS BUGGY

Joe Boggs reported that seed bugs (Order Hemiptera; Family Lygaeidae) found during this week'sBYGLive! Diagnostic Walk-About at Glenwood Gardens in Cincinnati provided excellent examples ofbug ID challenges that can make diagnostoids a bit buggy. Participants first came across a SMALLMILKWEED BUG (Lygaeus kalmii) hanging-out on a Canada thistle. The first ID challenge waspresented by finding the bug on a non-host, although the bug was not feeding. A number of identitieswere proposed including BOXELDER BUG (Boisea trivittatus).

Despite their common name, boxelder bugs can indeed be found on wide range of plants. Both thesmall milkweed bug and boxelder bug share the same general elongated body form and both sportgrayish-black and orangish-red color motifs. However, small milkweed bugs have black eyes whileboxelder bugs have red eyes. Also, the "red X" that is sometimes mistakenly ascribed to boxelder bugsactually appears on small milkweed bugs, although the "X" is more orangish-red. Boxelder bugs havewings outlined in orangish-red, and they have a broken orangish-red line that runs down the center oftheir back. The line ends at an inverted "V" produced by the orangish-red highlight crossing the middlepart of their wings.

<

The plot thickened when the group came across an ASTER-CONEFLOWER BUG (L. turcicus) on aplanting of Heliopsis spp. This bug presents two ID challenges. First, it does not have a commonname. The bug specializes in feeding on the developing seeds of plants in the Aster family(Asteraceae), so the aster-coneflower pseudo-common name, simply represents an amalgam ofcommon hosts. The second challenge is web-based. A web search will reveal that some websites givethe turcicus specific epithet to the small milkweed bug (wrong!). While the web offers great help ininsect identification, let the searcher beware!

The web mix-up between small milkweed bugs and aster-coneflower bugs can no doubt be traced totheir very similar appearance. Both are similar sized, both have black eyes, and both sportorangish-red "X" markings. However, the small milkweed bug has a very broad triangle in the top partof the "X" while the aster-coneflower bug has the triangle broken into two smaller arrow-shapedmarkings. Also, the orangish-red cross-marking on the "shoulders" of the small milkweed bug has twoblack spots which are lacking on the aster-coneflower bug. Finally, the plant host will tell the full story.Small milkweed bugs are very host-specific since they have adapted to feeding on toxic plants. Aster-coneflower bugs would be caught dead on milkweed.

WINDSHIELD WIPES - July 17, 2008BYGLers also ran into a number of other insects and mites including:



* Curtis Young reported that big beetles are beginning to show up at porch lights, screen doors, andsidewalks around Ohio. Two common representatives of these big beetles are the STAG BEETLES,sometimes called 'Pinching Bugs' (Psuedolucanus spp. and Lucanus spp.), and the SPOTTEDGRAPEVINE BEETLE (Pelidnota punctata). Stag beetles are brown to black and range in size from3/4-1 1/4" in length. They are so named because of the large stag horn-like branching mandibles of themales. No significant plant injury is attributed to the adults. Spotted grapevine beetles are tan totan-orange in color and about 1" in length. They have six black spots arranged along the edge of their

wings. The beetles can be found feeding on grapevine leaves, but they cause little damage. The immature stages of both types of beetlesare huge, white, grub-like larvae that live and feed in well-rotted logs and stumps. Neither beetle requires management.

* In the June 26, 2008 issue of BYGL, Curtis Young reported seeing numerous IMPORTED CABBAGE BUTTERFLIES (Pieris rapae)flying around flowering plants. Now reports of the offspring of these butterflies are coming in to BYGLers. The caterpillars are apparentlyfeeding on many of their favorite host plants in the family Brassicaceae (a.k.a. Cruciferae) (e.g., cabbage, broccoli, cauliflower, turnip,rapeseed, mustard, radish, and horseradish). Backyard gardeners are not going to be happy with all of the holes eaten in the leaves oftheir cabbage plants.

PLANT DIAGNOSTIC ACADEMY (PDA) DISEASE NOTESLast Wednesday-Friday, OSUʼs ENLT Team and Woodland Stewards Team conducted a three day Plant Diagnostic Academy (PDA) atthe Ohio Agricultural Research and Development Center (OARDC) and Secrest Arboretum in Wooster, Ohio. Here is our blight and blisterreport.

* OAK LEAF BLISTER was going strong on red oaks at Secrest Arboretum. Leaves had raised, reddish-brown 1/3-1/2" blisters on upperleaf surfaces, making some of the foliage look distorted, but causing little overall oak health problems.* GUIGNARDIA LEAF BLOTCH OFAESCULUS was going strong on horsechestnuts and buckeyes, especially on lower leaves where there was less air movement and thusmore potential for high relative humidity and leaf moisture periods long enough for fungal infections. Predictably, common horsechestnutand some of the horsechestnut-buckeye hybrids were most affected by this leaf blotch disease that results in brownish-red leaf blotches(often with yellow halos on the lesion edges). Red buckeye and bottlebrush buckeyes exhibited little to no disease incidence.

* Other disease notes from Secrest and the PDA included: light early incidence of POWDERY MILDEW OF MAGNOLIA resulting in somewhite mycelial growth of the fungus and the start of reddish to grayish leaf discoloration and desiccation; plenty of ROSE BLACK SPOT;some PHYLLOSTICTA LEAF SPOT OF MAPLE (tiny little brown lesions with red borders); and CEDAR HAWTORN RUST in which thefungus had not emerged yet from the undersides of the leaves, where fungal spores then blow back to the juniper hosts over the next fewmonths.

LOTS OF BEETLES = LOTS OF GRUBS???At the recent OTF Regional Seminar (July 14, 2008 at the Sylvania Country Club, Sylvania, Ohio),JAPANESE BEETLE (Popilla japonica) was a hot topic. The beetle has been emerging in large numbersin some areas of the state and has been emerging for a couple of weeks. A big problem that may be inour future from these large populations of adults is very large populations of new white grubs. A factorthat is going to contribute to the success of these beetles to produce large populations of white grubs isthe current soil moisture conditions. Soil moisture levels are high at the current time, which will make iteasier for female Japanese beetle adults to find suitable oviposition sites in which numerous of theireggs will hatch successfully.

Turf managers need to consider having to treat many more acres of turf for white grubs than they havein the past several years. A special note to golf course superintendents, your roughs and out-of-bounds areas may suffer greatly from thisnew batch of white grubs. All of these areas are maintaining high soil moisture contents, making them very susceptible to attack. If theseareas are not dealt with now, the raccoons and skunks will tell us with their diggings if these predictions come true.


OSU FactSheet on Japanese BeetleUniv. of Nebraska FactSheet on Japanese Beetle



ARE YOU A POTENTIAL CRIME SCENE?Your business may be an attractive target for those looking to cash in on the high price of metals. That is exactly what an Ohiogreenhouse owner reported to Dave Dyke! He went on to report the business owner lost a large number brass irrigation fittings (still in theoriginal packaging) collected over several years, copper wiring, pipe, and power tools to 3 thieves who broke into the greenhouse duringthe night. Although the alleged thieves were apprehended the following day, the metals had already been purchased and disposed of by ascrap metal yard (the tools were recovered). Business owners should be reminded that whenever possible, keep these types of items in asecure place. Identifying items with logos or company markings, along with a current equipment inventory, is a good investment of timeand money.

A RAIN GARDEN/LANDSCAPE WATER MANAGEMENT MANUALFOR SOUTHEAST OHIO UNDER DEVELOPMENT!Rain gardens are designed to capture and infiltrate rainwater in the landscape. There has been a lot of enthusiasm generated by articles,workshops, and the “Going Green” movement in Hamilton County. The Hamilton County Soil & Water Conservation District (HCSWCD)receives many calls a week asking for assistance in locating and designing rain gardens. Unfortunately, up until now, all of thepublications available have not been written to address local soils and growing climate.

As part of the Metropolitan Sewer District consent decree with USEPA for mitigation to sewer overflow, a new manual, Rain Gardens as aStormwater Management Tool in the Metropolitan Sewer District of Greater Cincinnati – Steps to Getting Off the StormWater "Grid", hasbeen written. Dave Dyke organized a committee of experts from the USEPA, The Cincinnati Zoo & Botanical Gardens, OSU, HamiltonCounty Soil and Water Conservation District (HCSWCD) and Storm Water District, the OARDC Urban Landscape Ecology Program, theENLT Team, and the Natural Resource Conservation Service, to put together a rain garden manual. Special emphasis was placed on soilamendments and both native and other cultivated plants.

You can access a copy of the 43 page manual by going to OSU Extension, Hamilton County website [ http://hamilton.osu.edu/Horticulture_Floriculture/guidelines-for-utilizing-rain-gardens/msd-manual-draft-3a-july-8-085.pdf/view ] or the website of the HCSWCD[www.hcswcd.org] and click on Newsletters & Publications in the left hand column. Please note that this is a draft with limited graphics.Additional graphics and sections on turf, contour plantings, and bio-retention will be added later this year. Please source this manual if anyparts are used for other publications or presentations.

FOUNDRY SAND IN SOIL APPLICATIONS FORUMEnvironmental Protection Agency (EPA), The Ohio State University, US Department of Agriculture (USDA), American Foundry Society,and Foundry Industry Recycling Starts Today are sponsoring a workshop on sustainable soil manufacturing July 23-24 at OSU's KottmanHall, 2021 Coffey Road, Columbus, Ohio.

This workshop will present information on the use of spent foundry sands as ingredients in manufactured soils. Foundry sands haveexcellent physical properties that are needed by many commercial soil blenders. Whether used to create general landscaping soils,nursery and horticultural soils, turf growth media, or biorentention soils, foundry sands present opportunities to achieve sustainability goalsby reusing materials that might otherwise be discarded.
