GDD (GROWING DEGREE DAYS)
GDD is a measure of the daily maximum and minimum temperature and directly relates to growth and development of plants and insects. The GDD of any zip code location in Ohio is estimated using the GDD of ten OARDC weather stations and available on the web at the site below.
The range of GDD accumulations in Ohio from north to south is 492 to 896. Following is a report of GDD for several locations around Ohio as of May 30, 2007: Painesville, 492; Cleveland, 539; Toledo, 616; Canfield, 579; Lima, 638; Wooster, 630; Coshocton, 632; Columbus, 708; Springfield, 772; Dayton, 790; Cincinnati, 840; Ironton, 874; Portsmouth, 877; Piketon, 896; Marietta, 845; and Jackson, 872.
To put these GDD accumulations into perspective, the following is an abbreviated listing of plant and insect species with their respective phenological event and average GDD accumulations at which these events occur. Due to variations in weather, temperature, humidity, etc., these events may occur a few days earlier or later than predicted by the average GDD. By looking at a city, town, or village near you from the above list, or visiting the above web site, you can see what could be taking place in the landscape around you.
Black locust, first bloom, 467; common ninebark, first bloom, 478; oystershell scale, egg hatch, 497; smokebush, first bloom, 501; arrowwood viburnum, first bloom, 534; American yellowwood, first bloom, 546; and bronze birch borer, adult emergence, 547; black locust, full bloom, 548; American Holly, first bloom, 556; mountain laurel, first bloom, 565; potato leafhopper, adult arrival, 568; juniper scale, egg hatch, 571; common ninebark, full bloom, 596; American yellowwood, full bloom, 599; arrowwood viburnum, full bloom, 621; multiflora rose, full bloom, 643; northern catalpa, first bloom, 675; black vine weevil, first leaf notching due to adult feeding, 677; Washington hawthorn, full bloom, 731; calico scale, egg hatch, 748; greater peach tree borer, adult emergence, 775; rhododendron borer, adult emergence, 815; northern catalpa, full bloom, 816; mountain laurel, full bloom, 822; dogwood borer, adult emergence, 830; oakleaf hydrangea, first bloom, 835; cottony maple scale, egg hatch, 851; panicle hydrangea, first bloom, 856; fall webworm, egg hatch (first generation), 867; mimosa webworm, egg hatch (first generation), 874; fuzzy deutzia, full bloom, 884; winged euonymus scale, egg hatch, 892; spruce budscale, egg hatch, 894; winterberry holly, full bloom, 897; and panicled goldenraintree, first bloom, 924.
Take some time to go to the GDD website at http://www.oardc.ohio-state.edu/gdd/ and see what it offers because it is more than just current GDDs. New additions to the Summary of Phenological Events chart include links to factsheets, bulletins and images related to most of the plants and pests highlighted on the web page. The information covered by these materials includes diseases, pests and research.

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 OF THE WEEK. YARROW (Achillea spp.) - Yarrow adds exciting color to the perennial border in late spring and early summer. The large flat yellow flowers are quite prominent and showy in any perennial border. Yarrow is extremely easy to grown and tolerates dry soils and full hot sun. The blooms can be cut for fresh bouquets; they make excellent dried flowers as well. Cut plants to the ground after blooming to encourage new growth and avoid the straggly stage for this plant. Heights range from 18" to 3' tall depending upon the cultivar and colors vary. Try 'Fireland' with the lacey foliage and bright reddish flowers or 'Summer Pastels' with a blend of apricot, salmon, scarlet, white, rose and yellow blooms.
*ANNUAL OF THE WEEK. Dragon Wings begonia (Begonia x hybrida 'Dragon Wings'). This hybrid cross between angel wing begonia and wax begonia offers the best qualities of both plants, growing denser and larger than most angel wing types with the heat tolerance of wax begonias. It is excellent in both beds and containers and thrives in the heat and humidity of Ohio summers, as evidenced by the selection of Dragon Wing Pink and Dragon Wing Red begonias as "Zoo's Best" winners in the 2002 Cincinnati Zoo and Botanical Garden Annual Plant Trials. Dragon Wing begonias are 18" - 24" tall, cane-forming plant with deep, glossy-green, 5" long leaves and drooping clusters of flowers. Because the hybrid is sterile, it blooms continuously from spring to frost and is available with red, pink or white flowers. It does best in fertile, well-drained but never dry, organic soil in the shade, or in the sun if given ample water. To keep it growing throughout the summer, make sure it is regularly fertilized.

THE WEEKLY WEED
While ORANGE HAWKWEED (Hieracium aurantiacum) was looking like the winner for weed of the week, COMMON PURSLANE (Portulaca oleracea) gained the upper hand when Randy Zondag pointed out that this summer annual needs to be controlled now. Warming soils have spurred the germination of summer annuals across the state. There is a tendency to control these weeds later in the season when they are larger. At this point, the plant may already be producing seed which will add to the weed population next year.
Common Purslane is currently very small in northern Ohio, but will go from germination to flowering in only 4 to 6 weeks. It is a low, sprawling plant with succulent red stems and oval leaves. The yellow flowers are small and usually go unnoticed. Most broad leaf weed control products will eliminate purslane. Because it is an annual, successive cultivations while the plant is young will eradicate multiple generations, but broken stems of the plant readily re-root at the nodes. Burndown herbicides work well, as do nonselective herbicides such as glyphosate. Control is relatively simple but timing is critical to get ahead in the weed control game.

TREE SQUIRREL SHENANIGANS
Extension personnel are reporting office inquiries concerning the removal of buds and bark from ornamental trees in the urban landscape. The damage accounts consisted of debarked sections of branches and removal of terminal and lateral buds on the plant material. Also reported, was the evidence of numerous gnaw marks across the xylem tissue of the affected plants. Ohio is home to several different species of tree squirrels. The tree squirrels genus Sciurus includes fox squirrel (S. niger), and eastern gray, (S. carolinensis). The genus Glaucomys contains the northern flying squirrel (G. sabrinus), which is found only in extreme northeastern Ohio and (G. volans), the southern flying squirrel, found throughout most parts of Ohio.
Tree squirrels inhabit our natural woodland areas. As with all living things, these animals are constantly searching for food, water, shelter and nesting material. Squirrels favor acorns, hickory nuts and walnuts in the fall. They seem to prefer tree buds in the spring. During summer they can be seen eating fruits, berries and plant material. Because they are opportunistic, they are occasionally seen raiding back yard bird feeders or bird nests for food. They will also dig up bulbs and planted seeds and may even sample ripened vegetables. The number of these animals in a yard is directly proportional to the amount of food, water and cover made available to them.
There are several theories as to why these animals strip bark from trees. Some believe this behavior is necessary to sharpen, clean and maintain their dental hygiene. Still others have written it is a process for gathering nesting materials. There are also accounts describing squirrels as being naturally "high strung" and mischievous creatures. This could explain why they also bite into communication and power lines. Some squirrels are designated small game species in Ohio and may be legally taken during the regular hunting season. In the urban areas, box trapping is an effective method to help manage population numbers. Check with your local wildlife officer for the legal options you have. Cultural controls include elimination of the animal's easy access to food, water, and cover in your yard. Finally, repellents can be applied to affected areas to prevent further damage. Products containing Naphthalene (moth balls), Capsaicin, and Polybutene are recommended.

BUG BYTES
|
GALLS, GALLS, GALLS, AND AN UN-GALL
Several BYGLers reported observing interesting plant galls demonstrating the diversity of insect and mite gall-makers gracing the Buckeye State. Representing the Dipteran gall-makers (midge flies), Curtis Young observed gnarled, green BOXELDER VEIN-POCKET GALLS arising from veins on the undersides of boxelder leaves. The galls are the handiwork of the midge fly Contarinia negundifolia. Curtis noted maggots were exposed (and presumably made angry) when he opened the galls.
The Homopteran gall-makers (aphids, psyllids, and phylloxerans) were represented by Jim Chatfield. He reported regaling in finding a great diagnostic workshop specimen by spotting a bountiful infestation of HICKORY PHYLLOXERAN GALLS on a hickory in the Chat-scape. The leathery, ball-like, hollow green galls are the creation of Phylloxera caryaecaulis and arise from new shoots and leaf petioles. Multiple galls may resemble a cluster of green grapes. Jim opened a few galls to find that the phylloxerans are still in the nymphal stage.
Joe Boggs represented the mighty-mite eriophyid gall-makers by reporting that the bizarre looking broccoli-like ASH INFLORESCENCE (FLOWER) GALLS created by the mite Eriophyes fraxinivorus are now becoming evident on the namesake host. The galls consist of a profusion of light green, clubby, distorted flower parts that eventually turn brownish-black and become unsightly later in the season.
Joe also noted that ERINEUM PATCH "GALLS" created by the eriophyid mite Acalitus fagerinea on American beech leaves, and the mite Eriophyes elongates on sugar maple leaves are becoming evident. There is a debate as to whether the felt-like erineum patches are "true galls." They appear to arise like scar tissue from leaf cell damage caused by mite feeding activity rather than by a gall-maker exuding chemicals to direct plant growth. Regardless, as the patches on beech turn from green, to gold, to brown, and the maple patches turn from green to red, they become very noticeable and are often mistaken for leaf spot diseases.

BOXELDER BUG-MANIA
Several BYGLers reported heavy boxelder bug (Boisea trivittatus) activity. Dave Dyke noted a call from a homeowner plagued by huge numbers of boxelder bugs meandering around their landscape, and Dave Shetlar observed heavy boxelder bug activity in landscapes in Columbus. This insect is most notorious for invading homes en masse in the fall as they search for winter quarters and in the early spring as they emerge from their winter nap. However, both the adults and nymphs suck plant juices and they may be encountered in large numbers feeding on plants during the growing season.
The 3/4" long boxelder bug adults are narrow-shaped, flat-backed, and dark gray or dark brownish-black. They have three highly visible orangish-red stripes running lengthwise on the pronotum, the area behind the head. The abdomens of the oblong-shaped nymphs are bright red with a faint orange line running down the middle, and an obvious orange spot in the middle of the line. Their antennae, head, thorax, legs, and wing-pads are bluish-black. When encountered in a home, the nymph's shape sometimes causes them to be mistaken for bed bugs.
Besides sucking juices from boxelder seeds, the bug commonly feeds on seeds of other trees in the genus Acer, as well as on ash. Boxelder bugs have even been observed feeding on alder, apple, buckeye, cactus, geranium, grape, honeysuckle, lilac, linden, oak, peach, plum, spirea, strawberry, and tulip. As seed-feeders, the bug causes no harm to the health of trees. However, their feeding activity on tree fruit and strawberries has been known to reduce fruit quality. The boxelder bugs wide-ranging feeding activity simply demonstrates that insects pay little attention to their common name.

FLIES REALLY BITE!
One of our BYGLers made the mistake of mixing terminology in the presence of several entomologists when referring to how some flies inflict pain. They were all over him like flies on s. . . well, you know what I mean. The slip of tongue made by the BYGLer was that the black flies were out in full force 'stinging' his party while they were trying to enjoy the great out doors. The problem is flies cannot sting. They do not possess an anatomical structure with which to sting. Stinging is done by insects in the Order Hymenoptera, the bees, wasps, hornets, yellow jackets and ants. These insects have a hard ovipositor (the stinger) connected to a venom gland. However, several species of flies can inflict pain by biting with hard mouth part structures. The terms sting and bite are not and should not be used interchangeably.
Flies that bite are after a blood meal and are usually female. If given the chance to bite and begin feeding, the fly usually spills or injects saliva into the wound to prevent the blood from clotting. Some people react to these fluids resulting in a localized allergic reaction. This exchange of fluids may also result in disease transmission between the fly and the host. Examples of biting flies include: STABLE FLIES; HORSE FLIES; DEER FLIES; BLACK FLIES; BITING MIDGES; and MOSQUITOES.
Hymenopterans that sting are frequently defending their colony or nesting site, and are always female. The 'sting' of being stung is not caused by being impaled by the stinger, but from the venom injected through the stinger into the wound. Venoms vary from one hymenopteran to another. Some people are highly allergic to the venoms and can have severe reactions to being stung. In some cases, the allergic reaction can quickly lead to the death of the victim. Disease transmission is not usually associated with stinging. Examples of stinging insects include: HONEY BEES; PAPER WASPS; YELLOW JACKETS; and FIRE ANTS.

IS THAT AN ANT OR A SPIDER?
Curtis Young reported observing a strangely behaving ant while visiting the Mahoning County Extension Office. The movements of the ant didn't look quite right. The thing that looked most odd was how the antennae were moving. They were moving too rapidly and jerky for a typical ant. Through a hand lens it was determined that the ant was not an ant at all, but rather an ANT MIMICING SPIDER belonging to the spider Family Salticidae, the jumping spiders. The mimic looked like a typical black field ant. The 'antennal' movements were jerky and rapid because the antennae were actually the front legs of the spider.
Mimicry can be used as either a defense or a deception. In some cases, one insect mimics another to avoid being eaten by a predator. In other cases, the mimic may be trying to slip past guards to a colony to get into the colony for a quick meal. Mimicry is a game of deception that can lead to misidentification. Thus, the take home lesson for this observation of a small insignificant ant mimic is to be careful, things aren't always what they appear to be. Look at specimens carefully with a hand lens or a dissecting scope to verify what you are truly seeing.

WINDSHIELD WIPES
BYGLers also ran into a few other insects and mites this week, including:
* HOLLYHOCKS BEING ATTACKED. Two perennial attackers of the hollyhocks are already doing their thing to make hollyhocks look ugly in the perennial garden, the HOLLYHOCK WEEVILS (Apion longirostre) and HOLLYHOCK SAWFLIES (Neoptilia malvacearum). Curtis Young reported seeing both of these pests nibbling away hollyhocks in Lima, Ohio.
*For individuals trying to grow sweet corn this year, they may wish to know that adult EUROPEAN CORN BORERS have begun to fly. Curtis Young reported seeing several adults at his porch lights over the past couple of nights. Although corn may not be in everyone's garden, European corn borers have used other crops and ornamental plants as alternate hosts when corn was not available (e.g., petioles of sugar beet leaves).
* COUCH POTATO LEAFHOPPERS ATTACKING AMERICA'S MIDSECTION. Potato leafhoppers are indeed beginning to arrive in production areas and landscapes in our area of the country. These tiny insects blow in from Southern states and feed on field crops as well as trees including crabapple and maple. Feeding can cause malformation of leaves and growing tips, as well as "hopper burn", the apparent scorching of the tissue resulting from feeding by large numbers of these insects.
* Dave Shetlar noted that GYPSY MOTH caterpillars are already at the 4th or 5th instar in Delaware county.

DISEASE DIGEST
|
DOTHISTROMA NEEDLE BLIGHT OF AUSTRIAN PINE
In the last several weeks the C. Wayne Ellett Plant and Pest Diagnostic Clinic has received several samples of Austrian pine with Dothistroma needle blight, a fungal disease caused by Dothistroma pini. Samples arrived from Pickaway, Lucas, Shelby, Franklin, Scioto, Union and Huron counties.
Dothistroma needle blight tends to be more severe on the lower branches, but can occur throughout the tree. The symptoms currently being seen are browning of the inner needles and spotting of the fully expanded needles which were developed in 2006. The fungus can infect needles from May to October, with intensification of symptoms from midsummer onward. In the late summer or fall, symptoms appear as spots or bands on the needles, often with a yellow margin. Eventually, the tip of the needle beyond the band will turn brown, leaving the base of the needle green. Infections developed during the 2006 growing season have started to produce spores, and these spores can produce additional infections (on needles developed during 2007) during periods of rainy, overcast, cool weather.
It is important to note that this disease is a needle disease. Unlike Diplodia tip blight; this pathogen does not invade the woody parts of the tree. Trees can be very unsightly but can be restored with care and treatment which may take several years. The difficulty with treatment is the cost and the fact that large trees will require equipment than many home gardeners do not have.
While recent research has shown some of the newer fungicides may be effective for control of Dothistroma needle blight, the products are not labeled. Copper fungicides can be used as well as fungicides containing mancozeb (for example, Junction® is labeled). Although the disease can be active from May to October, it is not practical to treat season-long. Most recommendations suggest two to several applications from the time new growth begins in the spring until sometime in June when new growth has hardened off. While additional infections can occur later in the summer, most occur early in the season.

MOIST CHAMBER
Other diseases noted by BYGLers around Ohio include:
* POWDERY MILDEW on common ninebark (Physocarpus opulifolius). The symptoms include leaf curling which can be confused with herbicide injury.

TURF TIPS
|
THIRSTY TURF SEEDS
The Extension Nursery, Landscape, Turf Team (ENLTT) conference call on Tuesday heard Educators from around the state reporting dry conditions in their areas. These favorable weather conditions across the state have made it possible for turfgrass seeding work to progress. Favorable weather conditions for lawn installations unfortunately are not always the most desirable for grass seed germination and turf establishment.
Successful seed germination is a simple process. Neglect any of the items in the process, and germination will not occur. First, the seed must be capable of germinating. Always purchase seed from a reputable dealer. Read the label to determine the germination percentage and testing date of the mixture you are considering. A grass seed is similar to other seeds in that it consists of an outer coat which protects a dormant seed embryo that is attached to a food supply. If the embryo in the seed is alive, it is said to be viable. In order to wake up a viable seed from dormancy, Nature requires the seed to be subjected to a few basic environmental conditions. Those conditions include availability of water, proper temperature, a supply of oxygen, and sometimes light. In the seed bed, the seed absorbs water and swells which activates enzymes that turn the seed food supply into soluble carbohydrates. The carbohydrates then move towards the embryo and provide the food necessary for cell division that in turn develops into new root and shoot growth.
Current environmental conditions around the state do not favor successful lawn seed germination because we are too dry. It is important to suggest to clients the need for additional water on newly seeded lawns. Application of clean straw or manufactured mulching materials can help conserve the moisture in the seed bed. Any experienced lawn care firm owner knows there is a big difference between lawn seed germination and lawn establishment. Our goal is to sprout this seeding and provide sufficient moisture for the new plant to send roots deep enough into the soil to help the plant survive wind and hard rain soil erosion on its way to becoming a successful lawn establishment.

MOWER OPERATOR OMISSION
Curtis Young reported observing strange circular patterns in commercial turf areas around Lima this week. When asked if he thought that we may be seeing another unidentified encounter as a result of alien spacecraft, he paused a moment and then said, "As best as I can tell, I believe the circular patterns are not the landing marks from an unidentified flying object, they are in fact, the landing marks of a commercial mower's bent cutting blade." We all breathed a sigh of relief as Dr. Young reassured us aliens had not landed in Lima. We certainly have too many other things to keep tract of and turf death by aliens would certainly tip us over the edge.
So, as for the bent mower blade, BYGL'ers would like to take the time to remind commercial turf care firms to rededicate themselves to practicing daily machinery maintenance and care. Mowing equipment used on an average of 8-10 hours each day logs nearly 50 hours of use per week. Many of us are moving into week 11 of the mowing season and these machines have seen a lot of terrain. For the most part, this mowing equipment was washed, greased, and properly adjusted for the start of the season. Employees should take the time each day to keep up with this important preventative maintenance part of the job. Inspecting the machinery they operate each day not only identifies performance issues with the equipment, but also exposes potential unsafe conditions for the operator and the unaware public that seem to always be around the mowing area.

PREVENTIVE CONTROL OF WHITE GRUBS IN LAWNS
Dave Shetlar, the BugDoc., reminded BYGLers about applying preventive controls for white grubs in lawns - especially those that had grub damage last year. The lawns that are irrigated and had evidence of grubs (skunks & racoons digging) last year are also at elevated risk. Now is the perfect time to apply the season-long grub control products, such as Merit, Mach II, and Arena. If granular products are used, they need to be applied before a rainfall event so that the product can reach the root zone. Products listed for preventive control have long soil residual and are meant to be applied before a potential grub problem develops.
It is too early to apply insecticides that provide curative control. They are normally applied during first three weeks of August, after the eggs have hatched and grubs are present and not too large. Two examples of such material are trichlorfon (Dylox) and carbaryl (Sevin).

INDUSTRY INSIGHT
|
GREENHOUSE/GARDEN CENTER SALES STRONG IN SOUTHWEST OHIO
During recent visits, Dave Dyke was greeted by growers pleased with strong spring sales. Other than some aphid and thrips, there have been few significant plant problems and sales have been very strong. One large upscale greenhouse/garden center owner reported that sales are up 50% to 60% from last year (but up only 2% the year before). He also reported that customers were purchasing 3 or 4 large ticket items, such as $90.00 container plantings, rather than a larger number of less costly items. Other growers also reported strong sales. Most attribute the good sales volume to the weather, which has been generally warm and sunny. For example, FIBROUS BEGONIAS, have been in very short supply, with some wholesale growers running out of those plants 2 weeks ago and some retailers finding their supplies depleted over the Memorial Day weekend.
