===================================================
April
is the cruelest month: Winter injury on ground covers, broadleaved
evergreens and herbaceous plants.
April
is a month that has inspired idyllic images in painting and
poetry, probably having beginnings back when our ancestors watched
the glaciers of the last ice age retreat. Unfortunately in the
Northeast, April is often less like its benign depictions but
more like that ancient scene left after a retreating glacier.
This seems especially true after this past winter, the weather
patterns of which left those who work in the green industry,
from landscapers to golf course professionals, scratching their
heads. After an autumn that never seemed to come to an end,
characterized by daytime highs into the 70's occurring as "late"
as January, the party finally ended with temperatures plummeting
before January ended. From all visual indications, the sudden
and protracted appearance of cold weather after such a long
and unusually warm autumn and early winter caused many plants
to be caught without having become properly acclimated to cold
temperatures. The result seems to be a greater than usual number
of calls to our diagnostic lab concerning injury to any number
of plants such as rhododendron. Some rhododendrons in the landscape
appear to have sustained damage from top to bottom. Others are
still somewhat green but have leaves on many branches that are
still rolled tightly, despite the return of milder weather.
Other plants, such as English Ivy have been described by some
callers as looking as though they have been "hit with a
sand blaster". Other species seem to have been victims
of total defoliation, where normally only some of the leaves
would have been lost during winter. The latter seems to have
been described concerning euonymus and American holly. From
the reports of callers, herbaceous plants have not escaped injury
from winter's sudden and late appearance. Instead of "a
host of golden daffodils" swaying above verdant foliage,
some daffs are displaying their blooms atop foliage with several
inches of browned tips, often with stunted dead buds within
the display. Daylily beds look equally bad, the late flush of
greenery that was present into January having received the cold
slap of reality when winter kicked in.
In
deciding what to do concerning winter injury on any given plant,
first be sure that the injury has indeed been caused by cold
and desiccation. Foliar leaf spot diseases may cause broadleaved
evergreen species to drop foliage. Cankers can kill stem tissue
of woody shrubs, causing flagging and browning of foliage. Poor
drainage can kill roots, especially after a wet summer, such
as that experienced in 2006. This, in turn, can cause above
ground plant parts to die. If winter injury is indeed discovered
to be the culprit, be sure that stem tissue is actually dead
before you begin to prune away injured portions. This is important
because if only foliar portions have sustained injury and not
the stem tissue, a new flush of growth may completely re-foliate
a shrub by the end of spring. Look for plump healthy buds on
the stem and nick the bark of twigs with your fingernail to
see if the stem is still green. Prune dead stems down to green
tissue. This practice can also be used for ivy beds or other
"vine types" of ground cover plants. The best thing
to do regarding bulbs such as daffodils is to let the plants
grow and flower normally, not cutting any foliage until it browns
and matures on its own. Perennials with injured foliage, such
as daylilies, will likely repair cosmetic damage with new growth
in time.
The
four seasons are not always as well behaved and timely in their
demeanor as we would like, but plants are usually much hardier
and more resilient than we realize. With some judicious observation,
we can usually address any injury that may have occurred. When
in doubt regarding the cause of your post-Winter landscape problems,
feel free to access the resources of your local Cooperative
Extension office for accurate diagnoses and the best way to
help solve the problem.

Asian Longhorned Beetle Infested
Trees Found on Uninhabited New York Island off Staten Island
WASHINGTON, March 12, 2007 - The U.S. Department of Agriculture's
Animal and Plant Health Inspection Service today announced evidence
of Asian longhorned beetle (ALB) infestation in hardwood trees
on Prall's Island, N.Y., an 80-acre, uninhabited island lying
between Staten Island, N.Y., and northern New Jersey.
Inspectors from APHIS' New York ALB eradication program in cooperation
with New York State Departments of Environmental Conservation
and Agriculture and Markets, surveyed the island on March 1
for signs of the ALB and discovered several heavily infested
red maple trees and infested gray birch trees. They found a
total of 15 infested trees upon their first inspections of the
northern sector of the island.
Several of the infested trees had the perfectly round ALB exit
holes that indicate beetles have emerged from the trees; healed-over
exit holes were also present, indicating the infestation is
more than a year old. All of the infested trees will be cut
down and the wood chipped to destroy all beetle larvae. Surveys
will continue at Prall's Island, weather permitting, to determine
the full scope of ALB infestation.
The property is owned by the New York City Department of Parks
and Recreation and maintained as a bird sanctuary. Prall's Island
lies outside of the established boundaries of the Middlesex-Union
County, N.J., ALB quarantine zone. As a result of this find,
quarantines will be placed on Prall's Island and on Staten Island
due to its proximity to Prall's Island. Surveys on Staten Island
will also take place to determine if any infestations occur
in that area. Quarantines are put in place to regulate movement
of firewood, lumber, nursery stock, tree limbs and other woody
materials that serve as hosts for the invasive beetle.
In New York, quarantines currently exist on Long Island in an
area bordering the Nassau County and Suffolk County boundary
line and also in the Islip area of Long Island. Portions of
Queens, Brooklyn and Manhattan are also quarantined. A total
of 132 square-miles are in quarantine in that state. The ALB
was first discovered in New York in 1996.
In New Jersey, two separate ALB infestations have been detected,
one in the Middlesex and Union County area in 2004 and the other
in Hudson County in 2002. With the Hudson County, N.J., quarantine
lifted in 2005, only 25 square-miles remain in quarantine in
that state. Hudson County, N.J., could be declared free of ALB
in 2008.
Chicago, Ill., where ALB was discovered in 1998, had the final
nine-mile quarantine lifted in 2006. Chicago could be declared
free of ALB by early 2008.
A mature ALB is about 1 to 1.5 inches long, has a shiny, jet
black body with distinctive white spots and long antennae that
are banded in black and white. The adult beetles are most evident
between June and October. As developing larvae during the winter
months, ALB tunnel through the heartwood of various tree species,
damaging the pathways that move water and nutrients throughout
the tree and ultimately killing the tree.
APHIS and its cooperators eradicate the ALB by imposing quarantines,
conducting visual inspections around confirmed sites to determine
the scope of infestations, removing infested and high-risk exposed
trees and chemically treating host trees as part of an area-wide
integrated pest eradication strategy.
The goal is to eliminate this destructive insect from the United
States before it can establish itself elsewhere.
APHIS' partners in the New York ALB cooperative eradication
program are the New York State Department of Agriculture and
Markets; New York City Department of Parks and Recreation; New
York State Department of Environmental Conservation and USDA's
Forest Service.
Also, Canadian officials told members of the NAPPO Forestry
Panel in late February that ALB had been detected again in Toronto;
the eradication program there must continue.

New Online Guide for Identifying the
World's Seeds and Fruits
By Erin Peadoy, USDA-ARS, March 2007
Scientists with the Agricultural Research Service (ARS) in Beltsville,
Md. have created a special online database called the "Family
Guide for Fruits and Seeds" for identifying the world's
myriad seeds and fruits.
Seeds are what enable plants, even those rooted well in one
spot, to disseminate their reproductive material over hundreds,
if not thousands, of miles. That's impressive when considering
the wide variety of plants we value and cherish including agricultural
crops that help feed and clothe us and the ornamental species
that make our gardens dazzle.
But invasive plants those ecologically destructive species that
are spreading at an alarming rate in the United States and elsewhere
also derive a big boost from scattering seeds. Small and lightweight,
seeds from invasive plants make the perfect stowaways, hitching
rides in cargo and plant material traversing the globe.
It falls to regulatory agencies, like USDA's Animal
and Plant Health Inspection Service, to try to stop the
entry and spread of noxious weeds into the country. The new
seed database created by ARS will be a critical tool to aid
their efforts, helping inspectors make tough and tricky seed
identifications.

(Holbrook, New York - March 14, 2007) - Be a part of the largest
environmental education event for composting. The U.S. Composting
Council officially invites you to join in celebrating International
Compost Awareness Week, May 6-12, 2007. Celebrated across the
United States, Canada, UK and Europe, composting advocates are
encouraging everyone to compost! This year's national poster
theme, "The Possibilities Are Endless - Compost!"
is a great way to get the message out. All types of composting
from backyard to large-scale, community-wide composting are
promoted during this week.
Compost Awareness Week is a fun and educational week of events
that offers an opportunity to learn more about the many benefits
of composting while enjoying interactive activities. To bring
positive attention to the possibilities that composting can
provide to communities, ICAW was designed to rally composting
advocates and build awareness in their communities. Compost
discussions, State ICAW proclamations, promotions with local
dealers and landscape supply stores, informal lectures by well-known
gardening experts, backyard composting bin promotions and urban
gardening programs are just some of the many events that are
held. To find out what's going on in your area - or to learn

Regional Updates
Westchester County
Well, spring has sprung!!! With green industry businesses moving
forward with their annual outdoor spring clean-ups, and some
daytime temperatures reaching the 60's over the past couple
of weeks, we can say without too much hesitation that the 2007
growing season has officially begun.
For much of the northeast region, the winter of 2006-2007 proved
to be a relatively warmer one, with temperatures on average
about three to four degrees above seasonal norms. Average winter
precipitation was significantly lower than normal with many
places indicating they received approximately half the amount
of expected totals for the winter of 2006-2007. Growing degree
day (GDD) accumulation has once again begun and as of April
1st, our count for Westchester County totaled 11 GDD.
Many entomologists / specialists seem to be speculating that
because of the warm winter weather we should be on the lookout
for higher emergence populations of overwintering landscape
insect and arthropod pests. Some of these may be visible right
now, including the eggs of spruce spider mite (SSM) and pine
bark adelgid as well as overwintering females (sometimes referred
to as "stem mothers") of the eastern spruce gall adelgid.
Other insects that may be visible include a variety of scale
insects such as the overwintering females of the azalea bark
scale and juniper scale. It is important to note that on a recent
scouting trip we observed very high populations of Hemlock Woolly
Adelgid (HWA). We noted large numbers of the "cottony-waxy"
substance that this insect produces and lives in, on a number
of hemlock shrubs that had been uninfested in previous growing
seasons. These substances were filled with overwintering females
that were busy feeding and laying plenty of their trademark
salmon-colored eggs.
As always, knowing the location of the these - and other - pests
allows a landscape professional to forecast areas that may require
follow-up monitoring or treatment as insect and arthropod emergence
occurs with the onset of warmer temperatures. Also, keep an
eye out for the elusive white pine weevil adults which may be
active (and managed) at this time in the growing season.
Read more about these and other common landscape pests (and
their management) in our newly printed 2007 Pest Management
Guide for Commercial Production and Maintenance of Trees and
Shrubs. They may be obtained by stopping in at your local Cooperative
Extension office. In Westchester County, green industry professionals
may call us at 914-946-3005 for more information or stop by
the office on 26 Legion Drive in Valhalla.

Orange County
Here in Orange County we have seen greenhouse pests starting
to become quite a nuisance- thrips on gerbera daisy, two-spotted
spider mites on herbs and sweet potato vines, aphids on sweet
potato vines, and whitefly outbreaks in many crops to name just
a few. Diseases like botrytis have flourished under some of
the cool cloudy conditions. We have not confirmed any Impatien
Necrotic Spot Virus (INSV) yet, but it has been a problem in
other areas.
There has been a lot of winter damage reported due to the cold
weather. I have seen elongate scale on Christmas trees and the
telltale brown banding of needles on Douglas fir from 2006 rhabdocline
needlecast.
I just received the first issue of Branching Out for this season.
It is full of field sightings and good information. I highly
recommend that you check out the subscription information online
at http://branchingout.cornell.edu/.
In our community horticulture lab we have received a lot of
questions on wildlife- chipmunks, squirrels and woodchucks.
Pruning, grubs, and ladybugs have also come up. I am sure that
with spring weather coming we will be getting a lot of gardening
calls!

Alternative Fungicides for Reduction
of Rhabdocline Needle-cast on Douglas Fir
Douglas fir is a major component of the Christmas tree and nursery
industries in New York State. Unfortunately during some recent
growing seasons weather conditions lead to severe cases of rhabdocline
needlecast. The infections are sometimes so severe that affected
trees appearance becomes unacceptable and the trees are lost.
One grower estimated losses of approximately $10,000 per year
due to a recent outbreak of this needle-cast disease.
Fungicides currently labeled for controlling Rhabdocline on
Douglas fir are perceived as costly and require repeated application.
Also, over-use of these labeled products is suspected to have
potential for adverse environmental effects and pest resistance.
Certainly, organic alternatives are being sought in nearly all
phases of agriculture, and they are increasingly demanded by
homeowners with children and pets. Even the perception of a
hazard can influence farm neighbors and customers, particularly
at cut-your-own operations.
Current IPM strategies recommended to control Rhabdocline include:
weed control (mowing), lower branch removal, selecting plant
sites with good air drainage, and removal of severely infected
trees. However there have been problems with IPM implementation
involving lack of growers time to perform the labor-intensive
tasks involved and a lack of efficacy information on possible
alternative products.
This problem prompted the implementation of an alternative Rhabdocline
needlecast control study sponsored by the New York State Integrated
Pest Management Program. The project was conducted on two farms
in Wayne County, New York. At each site 20 trees exhibiting
Rhabdocline needlecast were selected per treatment. Treatments
included: potassium bicarbonate, lime-sulfur, active compost-tea,
copper sulfate, with chlorothalonil for comparison. Rates and
frequency of application were from the label or manufacturers
recommendations. In general, it was a relatively low infection
season in the study area, probably due to the lack of rainfall
events during the sporulation period. This, along with several
other factors, makes definitive conclusions problematic. However
some indications can be mentioned.
The standard, chlorothalonil, was lowest in terms of both product
cost ($0.12 per tree per season) and labor cost (3 applications)
and gave acceptable control (0-2% infected needles). Of the
alternatives, potassium bicarbonate was least costly ($0.80
per tree per season, 4 applications) but did not provide acceptable
protection (7% infected). The copper sulfate pentahydrate product
cost was $2.24 per tree per season, had the highest number of
applications (7) and thus the highest labor costs and required
personal protective equipment (PPE). Control was acceptable
(1% infected). The compost-tea did not give an acceptable level
of control (3% infected), left a black residue similar to sooty
mold and had the highest product costs ($5.04 per tree per season,
4 applications). The lime-sulfur gave excellent protection but
at $1.28 per tree per season and high labor cost (5 applications,
requiring PPE) it may not be economically viable. The double
rate dormant application of lime-sulfur left a noticeable white
residue on older foliage that persisted into the following season.
If acceptable control can be achieved without the dormant application,
and with fewer seasonal applications, the costs may be brought
within reason.
While the economic information on material and labor costs should
give growers useful guidelines when selecting a treatment approach,
none of the treatments, as tested, gave us a clearly superior
alternative to chlorothalonil. The inability to predict infection
periods or detect the early stages of infection are both areas
requiring further research. Further testing of lime-sulfur may
yield an acceptable solution for those growers seeking an organic
approach.

New Greenhouse Miticide/Insecticide
has Potential for Use with Biological Control
The New York State Department of Environmental Conservation
has granted a Special Local Needs label for the Miticide/Insecticide
Judo (EPA Reg. No. 432-1280-59807) for greenhouse use on ornamental
plants, flowers, and foliage plants only. The Special Local
Needs labeling is assigned SLN No. NY-070001. Judo is allowed
for use in Nassau and Suffolk counties. Outdoor use is prohibited
pending data concerning impact on honeybees by the active ingredient,
spiromesifen. Applicators should have a copy of the SLN label
when applying Judo.
Judo is labeled for spider mites, tarsonemid mites (broad and
cyclamen) and tenuipalpid mites, and greenhouse, silverleaf
and sweet potato whiteflies (see label for specific species).
It is reported to be active on all mite development stages,
with juvenile stages more susceptible than adults, and to be
most active against whitefly nymphs and pupae. Dan Gilrein has
found Judo to be effective against the Q-biotype of silverleaf
whitefly (Bemisia argentifolii), which is less susceptible to
many of the insecticides currently used to manage the A and
B biotypes of silverleaf whitefly in the greenhouse, and has
the potential to become an increasing pest in New York State
greenhouses.
Judo is reported by the manufacturer to be soft on beneficial
insects used for biological control. Based on the Koppert Biological
Systems website on side effects (www.koppert.com
and click on Side Effects), it would be appropriate for use
with some of the common biological control agents for whitefly
or spider mites. Spiromesefin is listed as harmless to Encarsia
formosa adults and Amblyseius swirskii adults and eggs. However,
it is slightly to moderately harmful to adult Phytoseiulus persimilis.
There is no information concerning impact on other life stages
of these beneficial insects or on Eretmocerus eremicus or Amblyseius
californicus. While Judo has a reported residual control of
20-30 days, depending on the pest species, it has only short
residual effects (low persistence) on some of the beneficial
species. Persistence is 2-3 weeks for P. persimilis and 0 weeks
for A. swirskii and E. formosa, but has not been determined
for A. californicus or E. eremicus.
Spiromesefin is a lipid biosynthesis inhibitor in the class
tetronic acids and can be rotated with all other labeled miticides
for resistance management purposes. It affects water balance
in the insect, resulting in desiccation. Feeding stops after
one to two days and death occurs four to ten days after treatment.
While no injury has been reported on poinsettia, there is an
expanded list (not yet on the label) of plants that show sensitivity
to Judo. Other crops require the use of lower rates. Both lists
are included on the Judo product information bulletin. Growers
are advised to check for phytotoxicity on other crops, as not
all crops have been included in the manufacturers tests.
See our web site for the special needs label http://nysipm.cornell.edu/nursery_ghouse/newsletters/newsletters07/JUDO
SLN label.pdf
and the Tech bulletin for this product http://nysipm.cornell.edu/nursery_ghouse/newsletters/newsletters07/judo.asp

Whitefly Update Q & A (Biotype
B too)
The Q biotype whitefly is a new variant of the common A and
B biotypes of Bemisia whiteflies, the silverleaf whitefly and
sweet potato whitefly. (Biotypes are genetically distinct strains
of a species, similar to varieties of plant species, although
some have been given species designation.) Q and B biotypes
are visually indistinguishable and require lab tests for accurate
identification. Growers' first indication that they have Q biotype
is that the usual insecticides are less effective on what appears
to be silverleaf whiteflies (not greenhouse whitefly). However,
it is possible to have mixed populations of B and Q so lack
of efficacy may not be clear-cut.
There were at least six cases of Q biotype reported from New
York State greenhouses in 2006, on poinsettia and hibiscus.
If you suspect that you have Q biotype whiteflies, contact your
local Extension personnel and they can help you get the necessary
lab analysis and treatment options.
Following are some suggestions to growers on managing whiteflies,
particularly the Q-biotype whitefly:
Carefully check plant shipments for even low levels of whiteflies.
Use good non-chemical controls.
Correctly identify the whitefly species present!
Monitor whitefly population levels as the crop is growing.
Use sentinel plants to check for pesticide performance.
Consider using biological control right from the start.
For unusual silverleaf whitefly control problems, contact a
regional Extension specialist for more information on preparing
and shipping samples.
