GDD (GROWING DEGREE DAYS)
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 is available on the web at the site below.
The range of GDD accumulations in Ohio from north to south is 917 to 1,285. Following is a report of GDD for several locations around Ohio as of June 28, 2006: Painesville, 917; Cleveland, 961; Toledo, 1,058; Youngstown, 980; Lima, 1,009; Wooster, 1,018; Coshocton, 925; Columbus, 1,008; Springfield, 1,011; Dayton, 1,122; Cincinnati, 1,240; Ironton, 1,218; Portsmouth, 1,226; and Piketon, 1,285.
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 below web site, you can see what could be taking place in the landscape around you.
Panicled goldenraintree, first bloom, 924; June bride littleleaf linden, first bloom, 953; azalea bark scale, egg hatch, 957; Japanese beetle, adult emergence, 970; rosebay rhododendron, first bloom, 1,010; 'June bride' littleleaf linden, full bloom, 1,115; bottlebrush buckeye, first bloom, 1,158; Ural falsespirea, first bloom, 1,170; panicled goldenraintree, full bloom, 1,251; and Rose-of-Sharon, first bloom, 1,347.

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. Hemerocallis spp. - Hemerocallis in Greek means "beauty for a day" and it's true that each bloom lasts just a day. However, there are numerous buds on each flowering scape, keeping most plants in bloom for a month or more. Breeders have developed daylilies in every size and color imaginable except for blues. Plants bloom in early, mid-, or late season, and there are two reliable re-blooming cultivars. There are also "tetraploid" daylilies that have double the number of chromosomes for more abundant, larger, robust blooms with heavier texture. Numerous cultivars are available.
* WOODY PLANT OF THE WEEK. Aesculus parviflora - Bottlebrush Buckeye. This summer blooming shrub requires a soil with adequate moisture, and is otherwise highly adaptable. It will take full sun to partial shade. The bottlebrush buckeye is an exceptional landscape plant with a pleasing form that is accentuated by its attractive foliage. It is striking in bloom with flower stalks up to 12" long appearing in July. The plant will spread by suckers, but is considered by many as a slow grower.

DODDER
The annual topic of dodder popped up this week. Pam Bennett reported seeing it growing in containers of ornamentals during a trip to New York. Several other BYGLers had also noted that dodder (Cuscata spp.) seems to be coming more prevalent in the landscape.
Dodder is a parasitic vine that lacks chlorophyll, so it must extract food and nutrients from a host plant. There are many species of dodder found in the Untied States and each has a wide, but different, range of host plants. All species of dodder are annuals. Initially, seeds germinate and produce a temporary root system to support an initial thread-like stalk. If the stalk makes contact with a susceptible host, modified roots, called haustoria, penetrate the host plant. The red, orange, or yellow stalks continue to entwine the plant, often covering it under a mat of dodder stems.
Small white flowers are produced later in the season. Four tiny seeds are released from each fruit and remain viable in the soil for many years. As dodder lacks a specific seed dispersal mechanism, movement to new areas is through movement of contaminated soil on plants, shoes or equipment, or as a contaminant in seed.
Control is primarily through prevention. Avoid contamination from infested soil. If dodder is found, pull or prune to remove it from the site -- do not allow it to develop and set seed as this will provide a source of dodder for many seasons. For yearly problem spots, pre-emergent herbicides may provide some relief. Also, switching to another ornamental crop may leave the dodder without a preferred host.
And, what about the New York Dodder? As one BYGLer suggested "It's New York, just call it art!"

TREES DOWN IN WOOSTER
Last Thursday evening (June 22) a major windstorm ripped through the Wooster, Ohio, area, downing scores of large trees and branches throughout the city. Some areas of Wooster had power outages through the weekend. On Friday morning, Secrest Arboretum curator Ken Cochran and Jim Chatfield canceled or postponed a number of their meetings and went out to survey the damage in the Wooster area. They noted that damage occurred on a number of different trees, from red and white oaks to Callery pears, from sugar, red, silver and Norway maples to tuliptrees, magnolias and alas ... a few crabapples. Was damage on both the just and unjust? Or did problems conform to Joe Boggs' oft-quoting of Tom Smith (Spring Grove Cemetery and Arboretum, Cincinnati) that you almost always find flaws in fallen trees?
The vast majority of Ken and Jim's observations conformed to Tom's maxim: trees with no strong leaders, snapping at the juncture of multiple stems; trees that snapped off at the ground right at the point of girdling roots; trees with thoroughly rotted root systems or very poorly developed root systems; trees where damage occurred at areas of very poor crotch angles; and trees with considerable internal decay where a thin layer of cambium and sapwood was intact but all else was rotted and providing little support.
A number of trees which superficially may have seemed vigorous (normal-sized green leaves) exhibited their underlying stress (presumably root problems) with declining annual twig growth. One example was a Norway maple which had declined from 12" of new growth six years ago to a total of only 5" over the past four years. A good lesson of their survey: do periodic hazard and stress inventories of trees under your purview regularly, and in some cases decide to pay for pruning and removal now rather than later.

WICKED WEATHER DROWNS TOLEDO
Storms rolled through the Toledo area last Wednesday, June 21st, leaving residents cleaning up well into this week. Rainfall amounts from across the county ranged from 2" - 9", and came down very quickly. A spectacular lighting storm lasted for hours that same evening. The rain flooded basements, covered streets, and turn yards and fields into temporary lakes. Standing water remained in some areas for more than 48 hours, covering lawns and surrounding landscape plants.
Once the water began receding, areas remained brown from the mud. The common tree damage observed was pretty predictable -- flowering pear, silver maple, and emerald ash borer infested ash trees were high on the list of trees damaged. One week following the storms that dumped so much rain in so little time, the City of Toledo estimates that its refuse crews have picked up over 115 tons of materials damaged as a result of the rain.

JAPANESE BEETLES FLY!
Japanese beetles were spotted last week and over the weekend by many Extensioneers throughout Ohio. This observation surprised many as normally the beetles are spotted first in southern Ohio, then they slowly appear over a 2-3 week period progressing northward through the state.
This sudden emergence should prompt turf managers and landscapers to monitor their plants for these hungry iridescent beetles. The beetles are big fans of roses, linden trees, grapes, and Japanese maples. A few beetles will "scout" for delectable dinners, then via an aggregation pheromone, mobs of beetles will be attracted and arrive to munch on the plant as well. Turf managers who have procrastinated treating turfgrass which was damaged by grubs last year should decide within the next month whether or not to treat with a systemic insecticide. New research has shown that imidacloprid (e.g. Merit) can be applied as late as the end of August and still provide good control of grubs, however other secondary pests may not be controlled with this late application.

DON'T LET BAGWORMS SNEAK UP ON YOU!
As was reported in earlier editions of BYGL, bagworms (Thyridopteryx ephemeraeformis) have already hatched, and begun feeding and spinning their little bags. This week, several BYGLers reported observing and/or receiving samples of plants beginning to show evidence of bagworm feeding. It is amazing how rapidly some of these early season populations are producing severe enough damage to be seen from a distance.
Early detection of these populations is a must to prevent extensive damage to the more susceptible plants such as arborvitae, junipers, and spruces. In addition to these susceptible plants, there are numerous trees and shrubs that will host bagworm populations that may not suffer greatly from the feeding activity of the bagworm, but may ultimately serve as a reservoir for re-infestation of neighboring evergreens. Some examples of these plants are maples, honeylocusts, and crabapples. In landscapes where evergreens are regularly infested, these and other trees and shrubs should be inspected closely for infestations of bagworms.
For early season management, look closely for new larvae feeding on the foliage and traveling up and down stems and trunks. They may be difficult to see because they are so small and camouflaged by their new bags. Currently, the young bagworms have bags that look like either "dunce caps" or "spindles." Be sure to search and find new bagworms before treating. An infestation from last year is not a guarantee they will be there this year.
At this time the biological insecticide, Bacillus thuringiensis (Bt) (e.g., Biobit, Dipel, Thuricide, Caterpillar Attack) can be quite effective against the bagworm. But dont wait too long. Once the caterpillars reach 3/4" and bigger, the effectiveness of Bt declines rapidly. After this time, more traditional insecticides will be needed. However, dont wait till late in the growing season to manage the bagworm, because even the traditional insecticides lose their effectiveness against the large bagworms. Refer to OSU Extension Bulletin 504, "Insect and Mite Control on Woody Ornamentals and Herbaceous Perennials" for details on effective insecticides.

YELLOWNECKED CATS APPEAR
First generation YELLOWNECKED CATERPILLARS (Datana ministra) have appeared in southwest Ohio. Joe Boggs reported finding two colonies of this general defoliating "summer caterpillar" munching on leaves of a small oak tree. The moth caterpillars feed gregariously in colonies. First instars feed as leaf skeletonizers, and later instars consume entire leaves. The colonies typically focus their attention on defoliating one branch before moving to another. Small trees with multiple colonies can be rapidly defoliated.
Yellownecked caterpillars have black heads, and a bright orange "neck" (prothorax) that gives them their common name. The caterpillars pass through different "color phases" during their development. First instar caterpillars are copper-colored with no distinct lines. Second instars have distinct alternating longitudinal yellow and orangish-red lines. Caterpillars in the final instar stage have alternating longitudinal black and yellow lines. Although all instars are hairy, the hairs are most evident during the last instar stage. The various color motifs allow colonies to blend with the surrounding foliage of their hosts.
The caterpillars feed on a wide variety of trees and shrubs including: crabapples and other ornamental fruit trees, oak, maple, elm, beech, linden, honey locust, azalea, and boxwood. There are two and occasionally three generations per season. Early instar caterpillars are susceptible to the biological insecticide, Bacillus thuringiensis (Bt) (e.g., Dipel, Thuricide, or Caterpillar Attack). More traditional insecticides are needed to control later instars. A more direct (satisfying?) control method is to knock the caterpillar colonies to the ground and perform the "caterpillar dance." Thus far, no populations have developed resistance to this control method.

IT'S MOSQUITO TIME
Several BYGLers reported recent piercing experiences with mosquitoes and receiving calls generated by the annual emergence of west Nile virus media blabs ... 'tis the season. Most mosquitoes are poor flyers, so prevention begins at home. Mosquito larvae, or "wigglers," require some form of moisture to survive. Even temporary standing water will serve the purpose. Stagnate pools of water in ditches is an obvious mosquito generator. Less obvious are clogged gutters, tire swings, potted plant trays, outdoor toys, etc. Mosquito breeding sites will be revealed by a slow, close inspection around homes.
A number of larvacidal products are available for controlling mosquitoes where permanent pools of water are part of the landscape, such as aquatic gardens. The products are based on two naturally occurring bacteria: either Bacillus thuringiensis var. israelensis (Bti) (e.g. Vectobac, Aquabac, Mosquito Dunks, etc.), or B. spaericus (e.g. VectoLex). These products can be highly effective; however, users must read and follow label directions for maximum effect.
The search continues for the most fool-proof, ever-lasting method to fend off mosquitoes, but don't hold your breath. Mosquitoes are attracted to carbon dioxide exhaled by large animals (e.g. people). Dark clothing as well as certain floral scents in lotions and soaps also serve as "eat here" signs to mosquitoes. DEET (N,N-diethyl-meta-toluamide) is highly effective in repulsing mosquitoes, and two new compounds have been recently added to the repellent arsenal. They are picardin (also known as KBR 3023), and the active ingredient in oil of lemon eucalyptus (a.k.a. p-methane 3,8-diol, or PMD). Products containing these repellents are not fool-proof or ever-lasting; however, they can provide some protection and relief from buzzing blood-suckers.

RUFFLED OAKS ITCH
Barb Bloetscher reported that oak leaves with tightly curled margins were submitted to the CWEPPDC for diagnosis. Dave Shetlar identified the abnormal curling as the oak's response to GALL MIDGES (Contarinia spp.), and the presence of the OAK LEAF GALL MITES (Pyemotes herfsi).
The oak leaf gall mites feed on the gall midges. In the spring, the predaceous mites hide under the marginal leaf folds made by the gall midge larvae. The mites stab and release a toxic saliva into their gall midge prey. The midge larvae are immediately paralyzed and sucked dry by the mites. As she drinks, the mite's body swells and fills with new mites. Up to 250 adult mites will emerge from her body, mate and continue feeding on hapless midge larvae. As long as midge-food is available for the mites, they will continue to produce more mites. In late summer, when the midge larvae drop from the leaf-fold galls to pupate, the mites begin to drop as well, or they may overwinter in the galls.
It is at this time that the gall mites switch their behavior to becoming itch mites and begin to bite humans working outside around infested leaves. Itch mites are so named because they can cause dermatitis and some allergy symptoms on people. A tiny red welt surrounding a raised pimple will appear 10-16 hrs after a person is bitten, and may be incredibly itchy the first 10 days. If the bite doesnt become infected, the welt will last about 2 weeks. If itch mites are suspected, clean the bite and cover it to inhibit scratching. Wearing long pants, sleeved shirts and an insect repellent containing DEET will help to protect people from these irritating mites. Dave noted that the midge galls and associated predaceous mites are especially prevalent on red and pin oaks.

WINDSHIELD WIPES
BYGLers also ran into a few other arthropods this week including:
* Joe Boggs reported observing a heavy infestation involving multiple trees of a GALL-MAKING ERIOPHYID MITE on blackgum (tupelo). The mite, Eriophyes nyssae, produced small, rounded, light green galls that appear wart-like on the upper leaf surface and beadlike on the lower surface. Joe noted that although most leaves were heavily galled, the leaves appeared fully functional since there was no leaf discoloration or necrosis associated with the galls. Thus, the galls may have made the trees look bad, but were probably having little effect on the overall health of the trees.
* Barb Bloetscher reported that it's too late to treat for IRIS BORERS since the pinkish caterpillars have already descended down the leaves and are near or in the rhizomes. At this point, the grower should hunt and crush the caterpillars by squeezing feeding tunnels in the leaves, or by excavating and excising the caterpillars from infested rhizomes.

DISEASE DIGEST
|
THE CRABAPPLE PHILES
After several rain delays, Erik Draper and Jim Chatfield did their first disease ratings of crabapples in their Crablandia evaluation plots at Secrest Arboretum in Wooster last week. How do crabapple diseases compare to previous years? At least as of this first rating, 2006 appears to be a moderate year, with a bit less apple scab (Venturia inaequalis) than in 2005 and most other years. Of the 78 crabapple taxa in the plot this year there were 38 with no apple scab observed by our June rating, compared to 29 of the 72 taxa in the plot last year that exhibited no scab by the June rating. Data relative to degree of incidence for those taxa exhibiting some scab were similar; a little less than 2005. All this may change with new infections this season, but so far this year is not a Year of the Scab in Wooster.
Similarly, bacterial fireblight (Erwinia amylovora), and frogeye leaf spot (Botryosphaeria obtuse) also did not seem to be abnormally high or low: about an average year thus far in 2006. One thing they did observe was that fruit russeting was more severe on several taxa this year than had been noticed before. This brownish to grayish discoloration (as opposed to the greenish fungal growth on fruits of the apple scab fungus this time of year) is usually not a big problem, except for one or two crabapple taxa, but this year a number of taxa exhibited over 50% of their fruits russeted, which will result in considerable loss of ornamental effect of the usually attractive fruits on these crabapples. They suspect that this russeting was due to the effects of several frosts of blooms in the Wooster area this spring. Check out their full report on russeting in the OSU Ornamental Circular at the end of this season.

FUNGICIDES "FAIL," PART 4: IMPROPER TIMING
Once the disease is properly diagnosed and the right fungicide is selected, then everything should fall into place, right? Not. Another major reason for fungicide failures is improperly timed applications. The fact is that for fungicides to be effective, we must apply them before the disease develops. This is clearly true for "protectant" fungicides, and it is effectively true even for products which are described as "eradicants" and "curatives."
Let's use as an example rose black spot disease (pathogen: Diplocarpon rosae). The fungal pathogen infects through leaves of susceptible rose taxa if there are a certain number of hours of leaf wetness at a given temperature. Under these conditions spores germinate and penetrate the leaf surface and into leaf cells where the fungus establishes a host-parasite infection. Protectant fungicides are applied to the foliage to kill the fungus during its period of spore germination and attempted penetration of the leaf. These fungicides are essentially a toxic barrier to the fungus, preventing the fungus from getting inside the leaf where the infection occurs. If the fungicide is not present and infection does occur, some time later (typically a week or more) symptoms of black spot disease become evident (black spots, foliar yellowing, leaf drop, plant stress). Eradicant or curative fungicides provide a little leeway, along the order of getting rid of the fungus within 24-72 hours of initial infection.
There are several important things to keep in mind relative to this disease progression. First of all, you cannot see any of this happen, at least until symptoms of black spot develop, perhaps 7-10 days or more after initial infection. Diplocarpon rosae spores are invisible to the naked eye and we also cannot see the spores germinate, penetrate, or infect the leaf cells. Second, even the eradicant and curative products will not stop infections beyond a few days at most. So, you may spray a fungicide on what looks like a perfectly healthy, non-infected rose leaf which is nevertheless already infected and fated to develop rose black spot. When the disease develops, of course, we rage about the fungicide not working. The fact is that it never had a chance to work if it was applied after the infection was underway. This hardly seems fair, but such is the problem with disease control. It is largely preventive in nature. You must prevent infections, not see the disease symptoms and then try to get rid of the problem.
With most diseases, all is not necessarily lost once you see the disease, since in most cases the disease is reasonably localized and prevention of new infections is helpful in disease control even if you cannot get rid of the infections already present by using fungicides. Applications after symptoms are observed make sense if there is a repeating cycle of the disease on the host. For example, rose black spot keeps coming and coming all season long, so even if you see symptoms it makes sense to prevent new infections which will surely come if weather remains wet. However, with cedar hawthorn rust disease there is no repeating infection cycle on the hawthorn after initial infections in the spring, and once you see the rust spots on the leaves there is no reason to spray: what's done is done and there are no more infections that will come that season so more fungicide applications are beside the point. Of course, the key in both cases is to prevent initial infections - if the particular disease in question is deemed important enough to prevent. Remember, that each disease is unique and that understanding the disease cycle for that particular disease is the key to effective fungicide use.

TURF TIPS
|
TO SEED, OR NOT TO SEED?
BYGLers discussed recommendations to homeowners who have open areas in their lawns that need to be fixed. Specifically, can they seed this time of the year? Joe Rimelspach noted that as summer progresses and temperatures rise, the successful seeding of cool season grasses does indeed become more challenging. However, bare areas in lawns look bad and are an open invitation to weeds.
First, a more successful approach may be to use sod rather than seed. The up-side is that sod provides an immediate effect. Soil will be stabilized, weed seed germination suppressed, and the aesthetics of the lawn quickly improved. The down-side is that sod must match the surrounding turfgrass. For example, using Kentucky bluegrass sod in a turf-type tall fescue lawn will result in a very noticeable patch. Also, sod must be watered, watered, and watered until new roots grow into the underlying soil. Care must be taken not to promote turfgrass disease by the inappropriate application of water.
Second, if bare areas are going to be seeded, the same caveat regarding matching the new turfgrass to the existing lawn also applies. The use of "lawn patching" seed mixes that do not match surrounding grass species will do exactly as the name implies -- the lawn will look patchy! As with sod, newly seeded areas must be watered, watered, and watered to promote grass seed germination as well as to support the growth and establishment of the new seedlings. Again, there is a risk that inappropriate use of water (e.g. during high-heat conditions) may support turfgrass disease development.
Bottom line: bare areas in a lawn are likely to serve as footholds to lawn weeds, and bare soil is subject to soil erosion. It is better to take a risk and address the issue, rather than doing nothing and hoping for the best. Nothing ventured, nothing gained!

INDUSTRY INSIGHT

DEADLINE SET FOR 2007 GYPSY MOTH SUPPRESSION PROGRAM
The Ohio Department of Agriculture's (ODA) Gypsy Moth Suppression Program began in 1989. Because the gypsy moth is already established in 46 counties in Ohio, the goal of the suppression program is not to eliminate the moth, but to protect trees and reduce defoliation in these areas.
This voluntary program is coordinated and funded by ODA, USDA Forest Service, and private landowners wishing to participate through a 50/50 cost share. Landowners may request the state apply an aerial treatment for the gypsy moth by submitting an application through a "block coordinator" by September 1, 2006. Once the application is received, the ODA staff will then conduct a survey to determine if treatment block meets the criteria for suppression treatment.
Treatment criteria for an area include:
* Must be located in a county that has been designated quarantine for gypsy moth by ODA
* Must contain a minimum of 50 contiguous forested acres
* Must have a concentration of at least 250 egg masses per in residential forested areas, or 1000 egg masses per acre in uninhabited forested areas
* The proposed block must have a tree canopy that covers no less than 50% of the block
* Must consist of at least 35% of tree species that are either susceptible or slightly resistant to the gypsy moth
* Must receive a favorable T&E Assessment from ODNR and the US F&W Service
Once approved, cost share payment from the landowners will be due by March 1 of the treatment year. For additional information about the suppression program, ODA can be contacted by telephone at 614-728-6400, or on the web at: http://www.ohioagriculture.gov/gypsymoth/plnt-gyp-suppression.stm.

EYES ARE OPENENED TO EAB DEVASTATION
If a picture is worth a thousands words, how many words would the real thing be worth? It was the real thing that representatives from local, county, and state government saw during Wednesday's Emerald Ash Borer (EAB) Bus Tour sponsored by the Ohio Department of Natural Resources, Division of Forestry. Also represented were The United States Department of Agriculture/Animal Plant Health Inspection Service, The Ohio State University, and The Ohio Department of Agriculture.
Three busses explored Toledo and went 20 miles north into Michigan. Participants saw woodlots and creek beds full of thousands of dead ash trees, learned about EAB research including a host preference study of 200 ash trees planted in a median in North Toledo, and saw a 40 year old planting of infested ash trees being removed on a street in a West Toledo neighborhood. The lunch speaker was the City Director from Westland, a Michigan community that has been hard hit by EAB. He shared Westland's story and urged participants to begin planning for this insect that has cost his city millions of dollars.
Program planners want Ohio communities to be prepared for what is to come. City of Toledo forester, Craig Schaar, brought along two thermometers. He placed one in the front yard of a residence where trees had already been removed, and the other in a yard where a tree remained. The difference: nearly 20 degrees on a partly cloudy day. In addition to higher heating and cooling costs for residents, there was much discussion about the cost of ash tree removals, stump grinding, and replanting.

ASH UTILIZATION WORKSHOPS SCHEDULED IN JULY
Wondering what can you do with your ash? This workshop is geared towards the urban audience. As EAB moves through the state, there will be an enormous amount of ash material to be disposed of. Instead of chipping it all, there is a resource that can be utilized. Come find out what your options are. A brochure and registration materials for the program scheduled for Friday, July 7th in Findlay, and on Friday, July 21st in Delaware can be requested by contacting Amy Stone at 419-578-6783, or by email at stonea@ag.osu.edu.
