WEATHER WATCH
|
This week's weather summary includes data from July 1 - July 5, 2006. This weather summary includes information from 4 OARDC weather stations across the Buckeye state.
Once again there were weather extremes across the state, from the north, where rainfall was once again measured in inches, to the south where temperatures topped 90F. Amy Stone reported receiving 3" in the "Stonescape" late Monday evening. Erik Draper received nearly 2" of rain in Geauga County since Sunday. The rain that fell in southern Ohio was widely scattered and areas missed by the showers were dry following 3 consecutive days above 90F.

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 1,058 to 1,482. Following is a report of GDD for several locations around Ohio as of July 5, 2006: Painesville, 1,058; Cleveland, 1,107; Toledo, 1,220; Canfield, 1,132; Lima, 1,158; Wooster, 1,186; Coshocton, 1,095; Columbus, 1,178; Springfield, 1,163; Dayton, 1,319; Cincinnati, 1,482; Ironton, 1,426; Portsmouth, 1,434; and Piketon, 1,480.
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 nearby from the above list, or visiting the above web site, see what could be taking place in the landscape.
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; rose-of-Sharon, first bloom, 1,347; pine needle scale egg hatch, 1,349; euonymus scale, egg hatch - 2nd generation, 1,923; magnolia scale, egg hatch, 1,938; and banded ash clearwing borer, adult emergence, 2,195.
This is the last reporting of GDD for this year. Most locations for which GDD is reported have accumulated enough GDD's to have exceeded most of the pests and flowering plants that are included in the phenology table. Reporting of GDD will return in next year's BYGL. Thanks for following along!

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. Feather reed grass (Calamagrostis xacutiflora). One of the earlier-blooming ornamental grasses, feather reed grass, is in bloom at this time. The narrow, upright shape lends itself nicely to massed plantings in the perennial or landscape border. It gets about 3-5' tall and has green to pinkish flowers that last through the winter. 'Avalanche' has white-striped foliage and 'Karl Foerster' has a pink inflorescence that matures to a golden tan.
*WOODY ORNAMENTAL OF THE WEEK. Falsecypress (Chamaecyparis spp.). This genus is not that well-known and is often underused in landscapes but provides great choices for something "different" in the garden. Plants literally come in a variety of sizes, shapes, colors and textures and make great specimens or massed plantings. Try some of the smaller varieties as specimen plants in the perennial border or feature planting. C. obtuse 'Nana' is a very slow growing, dwarf, dense plant that gets to around 3-5' tall and has wonderful curly, graceful branches. C. pisifera 'Gold Mop' has yellow and green variegated, thread-like foliage that mounds to around 3-4' tall. C. pisifera 'Boulevard' has a great blue-green color and thread-like leaves and drooping branches. C. nootkatensis 'Pendula' is a gracefully branching, pendulous plant with elegant drooping branches. It's also a great plant to be used near water features and grows to 30' tall.

REVEALING WINDS IN LIMA
The wrath of Mother Nature was unleashed upon numerous counties across northern Ohio on Thursday, June 22. Curtis Young reported having to abandon his office and evacuate to the nearest sturdy structure with a basement that day. Local weather services recorded 80-100 mph winds with straight line blasts and five F0-F1 tornadoes in Van Wert and Allen counties.
Fortunately there were no human fatalities; although 17 people were injured by the storms. However, many trees of all ages, sizes and species did not fair as well. The tornado and straight line winds revealed many hidden weaknesses in the trees. The damage and destruction that occurred in some species was not surprising (e.g. Callery pears) but was much more surprising in other species (e.g. oaks) because of the hidden weaknesses that led to failures.
Following are some of the observations made by Curtis in Allen and Hardin counties following the storm: Numerous small limbs to major branches were twisted and ripped out of many basswoods, Callery pears, Chinese (lace bark) elms, honeylocusts, lindens, Norway maples, Siberian (lacey) elms and silver maples. Spruces and pines were either uprooted because of their relatively shallow root systems or snapped cleanly off at some point midway up their trunk. Many of these evergreens were 12-18" in diameter at breast height (DBH). Trees of many species broke at ground level or at double trunk unions causing additional damage as they fell to the ground. These failures were the most disturbing because of the factors that led to the collapses. For example, the OSU Lima Campus, where the Allen County Extension Office is located, lost over one dozen majestic black, red and white oaks and shag bark hickories. The breaks in these trees occurred because of extensive brace root and trunk rots, and bark inclusions between double-trunked trees. These trees were 18-24" in DBH. If any of these trees had fallen on a person, they would have been crushed.
One of the take home messages from these observations is to conduct periodic hazard and stress inventories of trees in public places before an unfortunate accident occurs. In addition, avoid developing these hazard trees with early maintenance in a trees' life before it develops bad growth patterns that could lead to bark inclusions. Finally, select trees that are not prone to developing problems.
Curtis made an interesting observation regarding the storm-damaged trees as he was examining some of the felled tree trunks. He observed FLATHEADED APPLE TREE BORER (Chrysobothris femorata) adults and other roundheaded borer (Cerambicidae) adults flocking to the damaged trees to lay their eggs. This is a common occurrence following major tree-destroying events during the summer.

MAGNOLIA SCALE A STICKY PROBLEM
Magnolia scale (Neolecanium cornuparvum) females are now pumping out copious quantities of sticky honeydew in southwest Ohio. Aside from possibly sticking homeowners to their sidewalks, the sugary honeydew also attracts bees and wasps and is frequently colonized on leaves, outdoor furniture, slow-moving gardeners, etc., by unsightly black sooty molds.
Magnolia scale is one of the largest "soft scales" found in Ohio with mature females measuring as much as 1/2" in diameter. The brownish-purple females will soon give birth to live young (nymphs) that hatch from eggs contained within the female's body. Production of nymphs, also called "crawlers," occurs over an extended period of time. New nymphs are found from late-July through early September, which presents a serious challenge to using topically applied insecticides. Multiple applications are required.
However, research conducted by Dan Herms (OSU Entomology) and others has shown that a single soil drench application of the systemic insecticide imidacloprid (Merit) made in the spring or fall is effective in reducing or eliminating populations. There is also anecdotal evidence that a soil drench application of imidacloprid made now not only reduces populations, but also halts honeydew production.

FIREFLY LOOK-A-LIKES
Joe Boggs noted that PENNSYLVANIA LEATHERWING (Chauliognathus pennsylvanicus) beetles, also called SOLDIER BEETLES, are now showing up in abundance on flowers in southwest Ohio. The elongate 1/2" long, soft-bodied beetles of this species are tannish-brown to yellowish-orange and have two oblong dark marks near the back of their front wings (elytra). These markings, coupled with the beetle's color, support the common name of soldier beetles because they appear to be in uniform. The soft, cloth-like structure of the elytra supports the other common name of leatherwings.
The elytra do not extend the full length of the beetle which leaves the tip of the banded abdomen exposed. Their exposed abdomens, size, shape, and general appearance make these beetles appear as dead-ringers for fireflies in some people's eyes. However, no amount of prodding or cajoling will cause them to flash as they lack the necessary bioluminescent equipment. Soldier beetles cause no harm to plants since they feed on pollen and nectar. Indeed, they are considered beneficial insects since they will also hunt down and consume caterpillars, aphids, and other soft-bodied insects that are plant pests.

AILANTHUS WEBWORM
Barb Bloetscher and Curtis Young reported observing ailanthus webworms (Atteva punctella) in western and central Ohio, respectively. Reports of plant pests generally solicit concerns; however, since the caterpillars of this ermine moth feed exclusively on the non-native, invasive TREE OF HEAVEN (Ailanthus altissima), their report generated delight, if not great hope!
The webworms produce nests by pulling several leaflets into a network of loose webbing. They live within the nests consuming the leaflets bound by the webbing. The webworms can grow up to 1-1 1/2" long and they have a wide, light greenish brown stripe down their backs and several thin, alternating white and olive green stripes along their sides. The caterpillars are sparsely covered with short, erect hairs, which help to suspend them within the webbing. When disturbed, the caterpillars move backwards out of the nest and drop towards the ground on strands of silk.
Ailanthus webworms are capable of defoliating their odoriferous namesake and may feed on stem tissue once all leaves are devoured. Unfortunately, such extreme damage is rare on large trees. Although feeding by this webworm has yet to halt the spread of tree of heaven, hope springs eternal since this is one of only a few insects known to infest this invasive plant.

SPIDER LOOK-A-LIKES
Joe Boggs reported receiving a phone call from a homeowner describing large numbers of "black-legged spiders" roaming among the leaves of their landscape shrubs. The "spiders" had reddish-orange abdomens which they held in an elevated position. Joe noted he was stumped trying to I.D. this unusual "spider" until he looked at photo images he had taken just last week. The images helped Joe to realize the critters in question were not spiders, but ASSASSIN BUG nymphs.
With their long, spindly black legs, these Hemipterans (true bugs) are indeed spider look-a-likes. And as with spiders, these descriptively named bugs are insecticidal maniacs! Spiders brandish fangs to dispatch their insect prey. Assassin bug nymphs and adults wield long, piercing-sucking mouthparts which are used like soda straws to extract the essence of insects. The bugs belong to the family Reduviidae which has over 160 species that are found in North America. All are predators. Like spiders, they should all be left undisturbed in their beneficial selection of prey!

JAPANESE BEETLES ON THE RISE
As was reported in last week's BYGL (BYGL 2006-13), some Japanese beetle (Popillia japonica) adults had already emerged across most of the state, seemingly and unusually synchronously. To add to the unexpected, Curtis Young reported massive populations of Japanese beetles accumulating on favored host plants, such as LITTLELEAF LINDENS (Tilia cordata). Curtis observed several linden trees on the campus of Ohio Northern University in Ada, Ohio that had been heavily damaged by the Japanese beetles. Their feeding had skeletonized 1/2 to entire canopies of trees approximately 15-20' tall. The unexpected part of this observation is that BYGLers, such as Joe Boggs in the southern part of Ohio have not seen any populations of this size yet this year. Usually, the southern BYGLers see the worst first!
Some factors that may have led to this unusual distribution of Japanese beetle populations include: distributions of last year's populations; more favorable environmental conditions for survival of larvae last year and this year; differences in levels of management undertaken at different sites; and amounts of rainfall over the past couple of weeks in the northern versus the southern parts of the state. The southern part of the state has been somewhat droughty while the northern part has been receiving abundant amounts of rain. However, once again the real take home message from these observations is that readers need to get out there and make observations to know for sure what is happening.

WINDSHIELD WIPES
Curtis Young and Barb Bloetscher reported hearing ANNUAL or "DOG-DAY" CICADAS (Tibicen spp.) in Ada and Columbus respectively. These cicadas emerge every year starting in mid-summer, although each species may take 2-5 years to complete their nymphal development. After emerging and continuing for about two months, the adult cicadas sing their droning song, an unmistakable sign of the season (Egad . . . already on the downward side of summer?).

DISEASE DIGEST
|
POWDERY MILDEW NOW?
Erik Draper reported that the first colonies of this fungal disease, which afflicts most of the vine crops, was spotted (ha ha) on leaves of butternut squash this week. The two fungi mainly responsible for wreaking this white demise on vine crops are namely Sphaerotheca fuliginea and Erysiphe cichoracearum with S. fuliginea being the most common in Ohio. Symptoms of powdery mildew develop quickly under favorable conditions such as high relative humidity, warm temperatures, low light (due to canopy density), high plant fertility, and succulent plant growth. These fungal spores are most often blown into Ohio during the spring from warmer southern areas where the disease over winters on plants. The older, mature foliage is most susceptible to infection while very young leaves are nearly immune. The length of time between infection and the appearance of symptoms is usually only 3-7 days.
As the fungus overwhelms the leaves, it causes them to wither up and die, resulting in the premature exposure of the fruit to the sun. This sudden exposure often causes the immature fruit to sunburn or ripen prematurely, form dinky fruit with poor taste, or have incomplete ripening from one side of the fruit to the other due to being overheated by the sun. It is especially annoying on pumpkins because the rind color will not develop consistently and the affected pumpkins don't seem to store as well or as long as unaffected fruit. A particularly annoying trait of infected pumpkin peduncles or "handles" is when they become dry and pithy, only to snap off at harvest. Control of these fungi is best achieved with genetic resistance; however, that resistance is prevalent mainly in cantaloupes and cucumbers. Fungicides are effective but must be applied when the first symptoms of powdery mildew are found and every 7-10 days thereafter, depending on the chemical, until harvest.

PEPPERS PEPPERED
Erik Draper reported that this has been an interesting year in the fields of northeast Ohio from a vegetable grower's point of view. The wind-driven rains appear to have started the current veggie dilemma by creating wounds for diseases to enter into plants. One of the prevalent diseases noted is BACTERIAL SPOT of tomatoes and peppers. Many growers were frustrated when it appeared that the applied fungicides failed. Of course they were not failures, they were just trying to control a bacterium with a fungicide, which by the way doesn't work! This disease invaded and overwhelmed many plants before it was correctly identified. With all of the driving rains and steady downpours, bacterial spot of peppers was happily splashed from plant to plant, all the way down the rows! This makes harvesting and care of these vegetables a real trial.
The challenge and trials come while trying to pick produce between cloudbursts. Hustling to get work done and vegetables picked, one naturally moves through a row of plants searching for any peppers or tomatoes. A few days later some of the leaves have spots and begin turning yellow around those spots. The spots appear to be defined by the veins, sort of angular rather than round. The leaves begin to turn yellow and those spots begin to dry up and drop out of the leaf. The really bad part is that because the plants were worked when the foliage was wet, the bacterium was spread right down the row, plant to plant.
Then to top it all off, that same disease can be transferred to both the bell peppers and tomatoes if they are worked when the foliage is wet. It all comes down to allowing the leaves to dry off before harvesting or working around the plants and applying a fixed copper spray to knock down the population of bacteria on the leaves. It also means not missing or skipping any copper sprays from that point on until the fruit is harvested. On the other hand, one of the best ways to get control of the disease is to pull out the infected plants and get rid of them.

WHY FUNGICIDES "FAIL," PART 6:
Over-reliance on Fungicides. Fungicides are an important tool in fungal disease control, but they are rarely stand-alone miracle answers to disease problems. Rose black spot provides a good example; it is important to remember the concept of the disease triangle. This simple, but important concept is that for disease to occur it is necessary for all three of the following to be present: a susceptible host, an environment conducive to disease, and a virulent pathogen. In managing a rose garden for rose black spot disease, attacking the components of the disease triangle means: 1). Planting as many rose taxa as possible that have good genetic resistance to black spot disease; 2). Limiting leaf wetness by avoiding overhead watering, by planting in the sun and otherwise promoting good leaf drying conditions; and 3). Limiting the pathogen. Limiting the pathogen involves good sanitation by removing diseased leaves and canes during and after the season, and the use of fungicides to prevent infections.
Of course, complete success in breaking the disease triangle at any point would control disease. For example, with the host part of the triangle, use of only roses with excellent genetic resistance to black spot would prevent the disease. Similarly, the environmental part of the disease triangle can be attacked by never allowing the leaves to get wet. This seems impossible until one realizes that greenhouse rose growers can do exactly that, with greenhouse roofs stopping the rain and through the use of trickle irrigation in which the leaves stay dry. Finally, complete sanitation of black-spotted rose tissue in the garden (and nearby gardens) or complete and perfect timing and coverage with the proper fungicides could theoretically break the pathogen component of the triangle.
Reality, though, is far different. Black spot susceptible roses are planted or inherited by the manager due to lack of information on resistance or because certain horticultural characteristics are desired from a particular rose taxon despite black spot susceptibility. As opposed to greenhouse production, roses grown outdoors are subject to unwanted and uncontrolled irrigation (rainfall); wet years mean bad black spot years. Finally, sanitation and fungicide timing and coverage are never perfect. The upshot of this is that one cannot rely on any single form of disease control; this includes fungicide use. Good plant health management programs require integrated approaches in which fungicides are only one component. Avoid the mistake of waiting until there is a major problem and then trying to solve it with a quick fix.

INDUSTRY INSIGHT

NUTRIENT DEFICIENCIES OF WOODY ORNAMENTALS
The two most common micro nutrient deficiencies of woody plants are Iron (Fe) and Manganese (Mn). Fe deficiency is particularly evident in Ohio on pin, white and scarlet oak, white pine, sweet gum, star magnolia and oriental photinia. Fe deficiencies are also common in acid loving plants such as Rhododendrons, Pieris, and blueberries. Iron exists in the soil as both ferric (Fe+3) and ferrous (Fe+2) cations. The Fe+2 form is thought to be the one that is actively taken up by plants. The root tips are extremely important in Fe uptake. The development of young root tips or destruction of root tips can strongly influence the availability of Fe to the plant. One source of Fe that can be applied to correct deficiencies is iron sulfate (FeS04). Trunk injections and implants in landscape trees of FeS04 have been effective for correcting deficiency symptoms for one season with oaks and other species.
Manganese deficiencies are particularly evident in Ohio on Norway, sugar, red, and silver maples, and flowering cherries. Mn plays an essential role in photosynthesis and respiration. Mn deficiency symptoms are often confused with iron and zinc because the chlorosis symptoms are similar. Leaves of deficient plants may develop pale, brownish or purplish spots. The incidence and severity of Mn deficiency appears to be somewhat dependent on seasonal conditions. The deficiency is often worse in cold wet seasons possibly because of a reduction in root metabolic activity affecting Mn uptake. One source of Mn for plants is manganese sulfate (MnS04). Implants of MnS04 have been effective in correcting Mn deficiencies.

WEED CONTROL IN MIXED LANDSCAPE BEDS
The recent frequent rains are extending weed seed germination over a longer period of time and are reducing the effectiveness of weed control procedures implemented earlier in the spring. Under the current conditions, it may be necessary to implement additional weed control practices in mixed landscape beds or nurseries. Mixed landscape beds include annual and herbaceous materials and woody shrubs and tress.
The most tender materials in a mixed bed are the annual flowers, followed closely by the herbaceous perennials. These plants are far more sensitive to herbicide injury than the woody plants in the bed, and in some cases are even more sensitive than the weeds. If one chooses to apply a preemergent herbicide to the chemical, physical and cultural controls already implemented this season, below is a list of some possible suggestions. Carefully read the labels of any of the products before using. Many are not safe on all plant materials or effective on all the weeds one may find in the mixed bed.
*Surflan A.S. T/O [Oryzalin] - do not apply to un-established ground covers or areas where chemical may runoff into lawns.
*Ronstar 50 WSP [Oxadiazon] - do not apply under wet conditions when granules can collect on the leaves; uniform application essential for control; does not leach or photodecompose; and do not apply to soft, annual flowering plants, ferns, or bulbs.
*Barricade [Prodiamine] - established wildflower & perennial beds and restrict quantity applied in season.
*Pendulum 2G [Pendimethalin] - do not apply in greenhouses, shadehouses or other enclosed structures and can be incorporated into landscape and grounds maintenance programs to provide extended preemergence control of most annual grasses and certain broadleaf weeds.
*Treflan 5G [Trifluralin] - greater rate on clay and loam soils, lower rate on sandy soil; do not apply on soil with high OM; incorporate twice in cross directions for best results; and does not control mustards, nightshades or ragweed
*Devrinol 2-G Ornamental [Napropamide] - do not apply to soil with high OM; do not apply more than once a season; and should be incorporated evenly into the soil using a hand cultivator to a depth of 1-2" or irrigation or natural moisture (rainfall or snow, 1/2" within 2-3 days) for optimum results.

GLYPHOSATE CARRYOVER DAMAGE
The symptoms of injury from phenoxy type herbicides such as 2, 4-D include: tip chlorosis, tip dieback, epinasty, twisting and abnormal foliage appearance. Symptoms depend on the concentration to which the plant has been exposed. Low concentrations cause shoot tips to twist, leaves become cup-shaped with margins curling up or down. Leaf petioles may bend down giving the plant a wilted look. At low concentrations, leaves which develop after contact may be long, strap-shaped, darker green in color with prominent veins. At higher concentrations, shoot tip and leaves turn chlorotic and die, eventually leading to the death of the entire plant.
The symptoms described above can also occur due to misapplications or drift from glyphosate (e.g. Round-up). Glyphosate is broken down quickly in the soil by microorganisms; however, once it is in a plant it breaks down very slowly. The glyphosate is bound in the plant during the growing season in which it was applied and phloem-transported throughout the plant the following spring, resulting in symptoms similar to 2, 4-D injury or what is called "carryover" injury. As a result, the most common type of injury seen with glyphosate is carryover injury. Carryover injury can persist for 1-3 years. It is often misdiagnosed, since the spraying of glyphosate occurred several months or years before and has long been forgotten. Carryover injury can occur on one branch of a plant and the rest of the plant may look normal, or the injury may be scattered over the crown, or all new growth may be effected.
