DISEASE ALERT
BOXWOOD BLIGHT – A NEW DISEASE IN THE NURSERY AND LANDSCAPE Within the past few years, boxwood blight, which is characterized by a leaf blight and shoot dieback of several
boxwood (Buxus sp.) species, has jumped the ‘pond’ from England and/or Western Europe to the U.S. either
through the importation (legal or not) of cuttings or container stock. Through the early winter months, this disease
has primarily been found on boxwood in the landscape as well as container and field-grown nursery stock in the
New England and Mid-Atlantic States into more recently Ohio, Virginia and North Carolina. So far, boxwood
blight has not been identified in Alabama. However, the recent discovery of boxwood blight on nursery stock in
Oregon indicates that this disease will be introduced into Alabama nurseries on diseased liners and container stock
as well into landscapes via diseased plants sourced from Mid-Atlantic States. There is considerable field and con-
tainer production of boxwood in North Alabama, while several nurseries produce container-grown plants in the
Baldwin-Mobile area.
Symptoms
The causal fungus Cylindrocladium pseudonaviculatum (C. buxicola) infects the leaves, shoots, and main stem(s)
of boxwood. On the leaves, early symptoms appear as light to dark brown spots that often have a dark brown bor-
der (Fig. 1A). Leaf spots, which may coalesce to cover much of the leaf surface (Fig. 1B), may eventually exhibit
a zonate or ‘target spot’ pattern. Eventually, badly disease brown or straw-colored leaves are shed leaving the dis-
eased plants almost completely defoliated (Fig. 1C). Brown to reddish-brown colored lesions with tan to light
brown centers form on the shoots and larger stems (Fig. 1D). Later the lesion surfaces as well as the underlying
tissues turn black (Fig. 1E). Boxwood typically does not succumb to boxwood blight. Symptomatic nursery field
or container stock is unattractive and unsalable, while diseased plants in the landscape are unsightly and may not
recover even with appropriate fungicide treatments. Unlike some Cylindrocladium sp. the causal fungus of box-
wood blight does not cause a root rot.
Pathogen Biology
The causal fungus C. pseudonaviculatum readily sporulates on leaves and shoots (Fig 2A). On the leaf under-
sides, a white layer of fruiting structures (sporodochia) on which conidia are produced (Fig. 2B). Similar struc-
tures may also be seen forming on stem lesions (Fig. 2C). The cylindrical, hyaline (clear) conidia are splash dis-
persed short distances to healthy leaves and shoots (Fig. 2D). Long distance spread occurs via the distribution of
‘diseased’ liners and nursery stock, which in reality may appear perfectly healthy until exposed to weather patterns
favoring infection and subsequent symptom development. While disease development may over a wide range of
temperatures up to 86F, ideal temperatures are in the mid-60’s to mid-70’s. Summer afternoon temperatures
above 91F over a week may be lethal to the causal fungus C. pseudonaviculatum. Depending on the location,
disease development on container or field stock in Alabama would most likely occur from mid-fall into mid-spring
during extended periods of wet, mild weather. While winter disease development probably would cease in North
Alabama due to low night temperatures, weather patterns may continue to favor boxwood blight development dur-
ing the winter months near the Gulf Coast. Disease development is also likely to occur all winter in North Ala-
bama on container stock or liners stored in unheated poly houses. Continued on next page...
INDUSTRY PUBLICATION DISCUSSES EARLY SEASON CORN FUNGICIDES This article is a nice summary of work done concerning early fungicide applications on corn. I agree that these
treatments have little value with respect to late season disease control, particularly for southern rust in Alabama.

Host Range
Boxwood blight has been reported on all cultivar species of boxwood, though there are differences in species and
cultivar susceptibility to this disease. The English boxwood (Buxus sempervierns ‘Suffruticosa’) and American or
common boxwood (B. sempervierns) are likely to suffer from heavy leaf spotting, defoliation, and shoot dieback.
Cultivars of the Korean B. sinica var. insularis), Japanese (B. microphylla var japonica), little leaf (B. microphyl-
la), and hybrid boxwoods (B. sinica var. insularis x B. sempervierns) have identified as hosts of boxwood blight.
Control
For Alabama nursery producers, scouting current stock as well as incoming liners and other plant material for
symptoms will be the key to preventing the accidental introduction of boxwood blight into a field or container
nursery. As previously noted, this disease is being spread on liners, B&B, and container stock from nursery to
nursery as well as from the nursery into home landscapes. Ideally, boxwood stock plants and liners should be
sourced from nurseries in areas of the U.S. where boxwood blight has not yet been found. Alabama propagators
should propagate cuttings taken from healthy stock plants known to be free of boxwood blight and other foliar dis-
eases such as Volutella blight rather than newly purchased plant material. Regardless of the source, all incoming
liners, B&B, and container boxwood stock received by a nursery must be isolated from existing boxwood stocks
and monitored for several weeks when weather patterns favor disease development for foliar symptoms. As a fur-
ther precaution, boxwood blocks, regardless of age and container size, should be scattered around a nursery rather
than located in a single block. Should suspicious leaf spot or blight symptoms appear, immediately send a sample
to the Auburn University Plant Diagnostic Laboratory and isolate disease stock. Should boxwood blight be diag-
nosed, burning and not recycling or composting diseased stock and media. Other sanitation practices that will help
slow disease spread include sanitizing any reused containers as well as collecting and burning fallen leaves and
other boxwood debris. Refer to ANR-359, ‘CONTROL OF DISEASES ON TREES AND SHRUBS’ for additional
information concerning the use of sanitation and other management practices to reduce the risk of disease in con-
tainer and field grown nursery stock.
While fungicides can be used to prevent the spread of boxwood blight to healthy plants, they will not ‘cure’ dis-
eased nursery stock or landscape plants. Ideally, protective fungicide applications should be made to liners during
the rooting process to prevent the accidental introduction and subsequent spread of boxwood blight. Depending on
the location, fungicide treatments may be needed on Alabama-grown boxwood in the spring and fall when mild
and wet weather patterns favor disease development. Along the Gulf Coast, the treatment window for boxwood
blight control may extend through the winter months. Since the fungus can attack all above-grown plant parts,
thorough coverage of the leaves, shoots, and stems with the fungicide mixture will also be critical for control of
boxwood blight.
Currently, little if any information is available concerning the efficacy of available fungicides or the ideal treat-
ment schedule required to control boxwood blight in the U.S. Some possible fungicides for controlling boxwood
blight are listed in this publication. Please refer to the product label for use instructions and restrictions, particular-
ly the target hosts, surfactant guidelines, and re-entry periods. Also, many cleared for use in nurseries and garden
centers are not registered for use in commercial or residential landscapes. Since numerous fungicide screening
trials are likely to be conducted in 2012 for the control of boxwood blight, modifications of the fungicide list are
likely to occur.
For residential landscapes, few fungicides can at this point be suggested for controlling boxwood blight. One of
the many formulations of chlorothalonil or mancozeb may be the best option for the control of this disease on box-
wood in the landscape. For best results, fungicide applications would have to begin either before or just as symp-
toms appear on the leaves. Repeat fungicide applications every 7 to 14 days depending on the fungicide selected
until weather conditions no longer favor disease development. Fungicide treatments will likely have to repeated
every year. As noted above, fungicides may have to be applied in the spring and fall to protect plants from attack
but should be unnecessary during the hotter and usually drier summer months. For severely boxwood blight dam-
aged plants, replacement of boxwood with another evergreen shrub such as a selection of Japanese, Compacta or
other dwarf holly may be necessary.

WATCH FOR IPM TRAINING EVENTS THIS SUMMER! In Spring 2012, ACES Regional Extension Agents (REAs) completed a
record number of horticulture crop production & IPM training work-
shops at various locations across the state. Remember, IPM covers in-
sect, disease and weed management. The workshops were catered to the
training needs of conventional AND organic producers. In other words,
the ACES Commercial Horticulture Team has now separate programs
for you in order to provide more in-depth training and to make a greater
impact (increase technology adoption).
At present, the REAs are planning the hands-on IPM Field Days and
there could be an event near you! An easy way to stay updated is to
subscribe to the newsletter sent out by REAs and subscribe to the Ala-
bama Vegetable IPM page on Facebook. If you are subscribed to the Alabama IPM Communicator weekly news-
letter (visit https://store.aces.edu/ListItems.aspx?CategoryID=180), then you are already receiving pest alerts and
messages from the IPM team. These are some of the many ways the ACES Commercial Horticulture Team is
reaching to many producers in Alabama and across the state line. Stay tuned!

INSECT ALERT
ROSE CHAFER DAMAGE TO GRAPES High spring temperatures caused an early rose chafer (Macrodactylus subspinosus Fabricius) development in vine-
yards this season. Rose chafer adults attack grapes at bloom as they emerge from the soil. Not only do they destroy
the fruit at blossom, in addition, they frequently skeletonize the leaves,
leaving only the large veins intact. This insect is especially abundant in
areas of light, sandy soil where beetles may appear suddenly as grapes
begin to bloom.
The adult rose chafer is a tan, slender, about 0.5 inches in length beetle
with a straw-colored body with black undersurface, a reddish head and
long, spiny, reddish legs (image on right). The female is somewhat more
robust than the male. The wings do not quite cover the abdomen. Eggs of
the rose chafer are oval, white, shiny in appearance, and about 1 to 2 mm
long. Larvae are C-shaped white grubs that resemble a May beetle larva,
but are smaller - up to 18 mm in length and more slender. Larvae are
found in sandy soil feeding on grass roots. The light yellow-brown pupa is 16 mm long and has the last larval skin
clinging to the posterior.
Life Cycle
Although the adult rose chafers become active in northeastern North America from late May to early June, we
observed them to emerge in early May in North Alabama vineyards during the last few years. The adults appear
suddenly. Beetles feed and mate soon after emerging from the soil and it is common to see mating pairs in the
newly formed grape clusters. Females deposit eggs singly a few centimeters below the soil surface. Mating and
egg laying occur continuously for about two weeks with each female depositing 24 to 36 eggs. The average
lifespan of the adult is about three weeks. Approximately two weeks after being deposited, eggs hatch into grubs.
The larvae feed on the roots of grasses, weeds, grains, and other plants throughout the summer, becoming fully
developed by autumn. Larvae move downward in the soil as soil temperatures decline and form an earthen cell in
which they overwinter. In the spring, larvae return to the soil surface, feed for
a short time, and pupate in May. After two weeks in the pupal stage the adults
emerge and crawl to the soil surface to begin their cycle again. There is one
generation per year.
Damage Symptoms
The adult rose chafer attacks the flowers (image on right), buds, foliage, and
fruit of numerous plants including grape, rose, strawberry, peach, cherry, ap-
ple, raspberry, blackberry, pear, hydrangea, clover, and many more plants,
trees, and shrubs. Adults emerge about the time of grape bloom and often
cause extensive damage to foliage. Blossom buds are often completely de-
stroyed, resulting in little or no grape production. Feeding activity on various plants may continue for four to six
weeks. Damage can be especially heavy in sandy areas. A toxin present in the beetles may kill poultry.
Monitoring
Scouting for this pest within your vineyard should begin in April. Newly emerged adults may be found feeding
upon young grape buds and foliage. If adult insect numbers reach 2 beetles per vine, control methods should be
utilized. Monitoring may also be conducted by utilizing the attractant developed for rose chafer. Traps should be
placed around the perimeter and dissecting the vineyard. For monitoring purposes these traps may be spaced every
100 ft. and should be checked daily for newly emerged chafers. Control methods should be considered if beetles

ROSE CHAFER DAMAGE TO GRAPES (CONTD.)
Management
When only a few beetles are present one may handpick them from the plant and destroy them. Where populations
are large and pose a threat to the grape crop, massive trapping may be a safe alternative to applying insecticide.
The desired effect of mass trapping, which is to bring the beetle population to below threshold level, is usually
achieved after a couple years of trapping. Chemical control methods should be utilized when beetle pressure ex-
ceeds an average of two beetles per vine.

DRAIN FLY AND “GNATS” IN HOME Fungus gnats and drain flies are often the nuisance pest in home. These are both flies, with several species in each
basic grouping, and their common names are given to them for good reason.
There are some similarities and differences between drain flies and fungus gnats.
Similarities: Both groups are small creature, live and breed in moist organic materials. They do not have the abil-
ity to bite or otherwise harm us and animals, simply a nuisance pest.
Differences:
Fungus gnats (in picture) can manage to breed in simply damp condi-
tions where tiny bits of mildew or mold may grow. Fungus gnats are
some of our tiniest flies, with thin, dark bodies that end in a point and a
pair of tiny, clear wings. The larvae will feed on mildew and fungi of some
sort the adult flies look for the damp conditions that will grow this food
resource.
Inside the home a common place to find perfect conditions for fungus
gnats will be house plants, more specifically the soils these plants grow
in. There may be other possibilities indoors as well, such as areas beneath
or around leaking plumbing, perhaps under the kitchen sink or, worse,
within walls where pipes and fittings may have begun to leak. It could be
carpets or other flooring below windows that are leaking rainwater inside,
catch pans under the fridge, mildew growing on or below a window sill
that has condensation dripping down off the window continually in the winter.
Drain flies (image next page) need a much larger buildup of organic materials to breed. Drain fly is also
called a “moth” fly, because it has wide and hairy wings resemble a tiny, gray moth, though it has only one pair of
wings (real moth has 2 pairs of wings). Drain fly is tiny, usually no larger than 1/8 inch. Inside home, common
places are sink, floor, or bathtub drains, as hair and many other things get washed into sinks there eventually
will be an accumulation that could even become a complete plug in that drain (photo 3). Another coomon breed-
ing habitat is the inaccessible “overflow drain” where overflowing water gets into through the overflow hole in
the sink. These areas remain continually wet, with organic buildup coating the sides of the pipes below the sink,
and drain flies look at this as just heavenly.

DRAIN FLIES AND “GNATS” IN HOME (CONTD.)
Control: For control of these gnats and most other nuisance flies we cannot
focus on controlling the adult fly. There is no reason to set off bug "bombs" in
the home, and very little reason to use other kinds of aerosol foggers to spray
in the air.
Effort should focus on identify and eliminate the conditions that allow them to
breed and live. Otherwise, the flies will be quickly replaced by new flies com-
ing from larval habitat.
Gnat control, obviously, is to eliminate the water problem, for it definitely is a
"problem" that needs to be corrected.
Drain flies are controlled by cleaning the drains or other areas of or-
ganic buildup, especially the over-flow drain and build-ups. There are
not harsh and dangerous drain cleaners, but are products that use bacterial
or enzymatic action to actually eat the organic buildup and allow it to be
washed away. It may take a few days to a week, but the result is far friendli-
er to the environment and to your family than the use of caustic cleaners.
Also pesticide use is not encouraged in control of these nuisance flies.
There are gel products on market but none products are more efficient than
Eliminating Breeding Habitats in home.

IPM IN ORGANIC VEGETABLE PRODUCTION This article briefly describes some basic approaches to organic crop pro-
duction and pest management. The first step to pest management starts with
pest monitoring & scouting. Remember, pest prevention should be the IPM
goal in organic cropping system not pest control. Don’t try to control 100%
of the pest populations, try alternative integrated pest management tactics
to reduce the onslaught of insects and prevent buildup.
Grow vigorous vegetable varieties! Organic crop production is harder
than conventional system, and one of the best pest management tools for the organic gardeners is choosing the
right plant variety for your garden. Choose vigorous crop hybrids with multiple disease and insect resistance,
when available. This will reduce dependence on insecticides that are generally quite expensive.
Organic producers should use cultural control tactics. Use mechanical and cultural insect control tactics first to
reduce or repel insects on crops. For example, use trap cropping and companion planting to confuse insects from
finding your crop. You can use pieces of bird nets and row covers to cover fruits and stem portions to reduce
squash bug and vine borers. Stem collars and nets may also work well to keep cutworms away.
Apply living insecticides the right way! Organic insecticides are often slow acting or don’t last very long after
application. Insecticides like Bacillus thruringiensis (DiPel) and Beauveria bassiana (Mycotrol-O) applied on top
of leaves may die quickly from direct solar radiation and high temperature. Botanical insecticides, like neem and
pyrethrin, are also susceptible to solar radiation and rainfall. Therefore, it is recommended to apply above insecti-
cides to the underside of leaves (during evening hours) in order to extend the life of products. It is also a good idea
to treat the bottom stems and soil at the plant base with insecticides in order to contaminate insects jumping off the
plant as you spray.

IPM IN ORGANIC VEGETABLE PRODUCTION (CONTD.)
Rotate insecticides! Not all organic insecticides are safe to beneficial insect, so
choose insecticides carefully and apply timely for maximum effectiveness. Make
sure that you also rotate insecticides to prevent resistance buildup (YES, insects can
become resistant to some organic insecticides). Commercial organic producers
should purchase OMRI-approved industrial formulations instead of over the counter
gardening products in order to get strong and effective formulations that can be
applied using small equipment. Organic producers should also consult their certify-
ing agency to ensure compliance with the National Organic Program Standards
(NOP) for pest management and get a list of approved pesticides.
Want to know more about the NOP pest management recommendations? Then stay tuned for the next issue of this
newsletter AND come to organic production field events! Contact a Regional Extension Agent today.
