100-Years of Extension! Whereby, county
agents that have lifted up America’s farmers; enabling
them to become the most productive mankind has ever
known. I charge all of us to take the time in the next few
months, before this centennial year passes, to rediscover
how this legislation called Smith-Lever was so
successfully delivered; Don’t forget to let your urban
neighbor know!
Stories to tell – you bet! Henry C. Whiteford was the
first County Agricultural Agent in Anne Arundel County
Office, located in Annapolis, Maryland. Mr. Whiteford was
an Engineering graduate from the University of Maryland.
In 1916 Henry C. Whiteford spent 84% of his time in
the field and 16% of his time in the office and traveled
exclusively on horseback covering 9,611 miles in Anne
Arundel County to make 976 farm visits, conducting 36
on-farm demonstrations, 182 farmer meetings with a
total attendance of 1,092. Henry wrote and mailed 2,625
letters, published 65 local Extension articles, and
distributed 750 USDA Agricultural Bulletins and 112
University of Maryland, College of Agriculture Bulletins.
Henry received 387 calls directly to his home phone and
157 office phone calls.
In 1916 Henry started the first Maryland Hog Cholera
Eradication Program, personally vaccinating 600 hogs and
treating 1,000 hogs for mange in the county. Hog
cholera outbreaks were quickly brought under control in
the county; Henry stated, “They were uncountable at the
outset to just six reported cases in 1918.”
Henry was instrumental in moving farmers from draft
animals to tractors, reporting in 1916 that he personally
consulted on each purchase of the 24 tractors being used
in the county.
Henry’s on-farm demonstrations documented an
average corn yield increase from 46.5 bushels/acre to
66.5 bushels/acre; and a 400lb/acre tobacco yield
increase to 1200lb/acre. He conducted 62 orchard
inspections, mainly peach production.
“Champion” the best peach variety, he stated,
yielded an average of $15/tree of peaches.
Growing, harvesting and selling the peaches
from 30 Champion peach trees, a farmer could
purchase a Ford Model T truck!

County Agent. Big shoes to fill!

Potatoes
Continue to scout fields for Colorado potato beetle (CPB)
and leafhoppers. Adult CPB as well as the small and
large larvae can now be found. A treatment should be
considered for adults when you find 25 beetles per 50
plants and defoliation has reached the 10% level. Once
larvae are detected, the threshold is 4 small larvae per
plant or 1.5 large larvae per plant. As a general
guideline, controls should be applied for leafhoppers if
you find ½ to one adult per sweep and/or one nymph
per every 10 leaves.
Snap Beans
Continue to sample all seedling stage fields for
leafhopper and thrips activity. The thrips threshold is 56 per leaflet and the leafhopper threshold is 5 per
sweep. If both insects are present, the threshold for
each should be reduced by one third. As a general
guideline, once corn borer catches reach 2 per night,
fresh market and processing snap beans in the bud to
pin stages should be sprayed for corn borer. Sprays will
be needed at the bud and pin stages on processing
beans.

Vegetable Crop Insects

Cucumbers
Although populations of cucumber
beetles can vary from field to field,
higher populations are present in
fields with a history of problems.
Fresh market cucumbers are
susceptible to bacterial wilt that is vectored by the
beetles, so treatments should be applied before beetles
feed extensively on cotyledons and the first true leaves.
Although pickling cucumbers have a tolerance to wilt, a
treatment may still be needed for machine-harvested
pickling cucumbers when 5% of plants are infested with
beetles and/or plants are showing fresh feeding injury.
A treatment should be applied for aphids if 10 to 20
percent of the plants are infested with aphids with 5 or
more aphids per leaf.
Sweet Corn
Continue to sample seedling stage
fields for cutworms and flea beetles.
You should also sample whorl through
pre-tassel stage corn for corn borers
and corn earworms. A treatment
should be applied if 15% of the plants
are infested with larvae. The first silk sprays will be
needed for corn earworm as soon as ear shanks are
visible.

IPM Alert: What’s Happening with
the Brown Marmorated Stink Bug?
insects kills it but a gradual freezing is something this
insect species is built to withstand.
On the parasite research end, Tim Haye of CABI has
been looking at the parasite waspTrissolus japonica. Dr.
Hayes has been looking at this parasite in mulberry, and
jujube orchards in china just outside of Beijing. He found
that this species of wasp can parasitize up to 50% of the
egg mass of BMSB.
By Stanton Gill, UME Extension Specialist,

Did you ever wonder what happened to all of the
brown marmorated stinkbugs? Remember 2011 and
2012 when they were everywhere? Yeah, sure they are
still lingering around in a couple houses but most people
are reporting they just are not a big problem in their
house or garden this season. There was a good number
overwintering in people’s houses this winter but the late
cold, spring has delayed their movement to the outside
this year and many people are
reporting they are finding them dead
in their house – as if they just ran out
of energy. In many landscapes we
found many of our well established
predators feeding on brown
marmorated stink bugs. Several
parasitic wasp have also be found
attacking different life stages of the
bug. Many people are reporting seeing several species of
birds feeding on the bugs. This and the strange spring
weather appear to be combining to help keep this pest
suppressed in several areas in Maryland. There are still
a few hot spots like Frederick and Washington county
areas. Many of the orchards in these counties are
seeing a fair amount of damage on peaches, pears,
plums and apples.
If you are seeing lots of activity from brown
marmorated stinkbug in your area let me know. We
would like to see if there are hotspots in Maryland where
this bug is very active. Sgill@umd.edu or 410-868-9400.
Wheat Scab Management
By: Jarrod O. Miller, Ph.D., Agricultural Educator
We have made it through another season of winter
wheat, but concerns about scab should not diminish.
The effects of fusarium head blight (FHB) include
bleached, shriveled and lightweight kernels, often
identified as “tombstones” in wheat. These tombstones
can contain a mycotoxin called DON, and is restricted for
both animal and human consumption. A combination of
resistance to FHB and correctly timed fungicide
application is recommended to reduce DON in wheat. If
you still have the presence of tombstones in your fields,
there are harvesting methods to reduce infected wheat
from entering the storage bin. Nathan Kleczewski
(Delaware Extension Plant Pathologist) recommends
increasing combine fan speeds to help blow out diseased
wheat. In a recent study from Ohio State1, increasing
the combine shutter opening from 70 to 90mm (with a
1,375 rpm fan speed) in-creased test weights in wheat.
Diseased kernels can lower test weights, also causing
price discounts. Combined with the presence of DON
(>2%), these price discounts could considerably lower
profitability. If infected kernels do make it into storage
bins, Purdue University recommends2 drying grains to
18% moisture to stop DON production. Further drying
to 13% moisture should also prevent spoilage by fungi.
Lighter kernels tend to accumulate in the center of grain
bins and all attempts should be made to keep infected
grains from mixing in.
This last week I attended a conference organized by
USDA at the Delaware University Research Center in
Georgetown, Delaware to find out what is the latest
research on brown marmorated stink bugs. The bug has
been on the move. It is now getting established in
southern California and in the agricultural areas around
Sacramento. This is a big concern since it has the
potential to become a huge problem in orchards,
vineyards and vegetable production areas. California
produces 90 % of the almonds for the world and the
BMSB feeds heavily on a close cousin of the almond tree
– the peach. It is suspected that it will become a
problem for almond growers.
Following harvesting, planning for the next season
should begin. Since no one solution is effective by itself,
integrated management is the best method to limit FHB
damage. Reduced and no-till systems are great for soil
health, but corn and wheat residue provide a home to
FHB over the winter. To reduce the economic impacts
of FHB, it is recommended to couple moderately
resistant varieties of wheat with proper fungicide
application and harvesting techniques. It has also been
observed3 that FHB can travel up to 2500 feet from the
source, so adjacent fields could be infected the following
spring, no matter what your rotation is. Ehen choosing
resistant varieties of wheat to plant this upcoming fall
The BMSB has also established in Northern Italy and
parts of Milan and Torreno, parts of France, and
Switzerland. It has also been found in Hungary.
One of the questions that has come up is how cold
winters impact the brown marmorated stink bug.
Theresa Cira of the University of Minnesota reported on
this pest in Minnesota. The winter temperatures in
Northern Minnesota reach -35 F and -25 F in southern
Minnesota this past winter. She reports that BMSB
survived the frigid Minnesota winter by using special
proteins to regulate the way their body freezes and
minimize damage to cells. A rapid freeze down of the

extension tab. Contact your local extension office for

sulfate (MnSO4) at 4 lb/acre, lessoning the likelihood of
yield loss.
Look closely at the affected plants and ask yourself the
following questions:
Could there be any herbicide carryover?
Has there been adequate rainfall?

Have the temperatures been cooler than normal?
Are the younger leaves yellower than the older leaves?
Are the veins in the leaves a darker green?
Are any spider mites present?
If there are no spider mites present and the younger
leaves are yellower with greener veins, then manganese
is a suspect.
Yellow Soybeans May Reveal
Manganese Deficiency Hot Spots
We need to now concentrate on the plant roots and soil.
Do the roots appear healthy with good rhizobium
nodulation?
By R. David Myers
UME Principal Agent
myersrd@umd.edu
When the soybeans were planted did you use the
proper rhizobium inoculant, and a seed treater that
contains fungicides, and molybdenum for the
promotion of enhanced rhizobium activity?
Several farms have reported yellowing soybeans
typically, but not always on knolls within the field.
Manganese (Mn) deficiency may be the culprit, however,
there are other soybean antagonists with similar
symptoms that need to be ruled out as causal agents.
Manganese deficiency most often occurs in over-limed
soils, where the pH is > 6.8.
After cutting a nodule open the inside should be pink
-- Is it?
Both molybdenum and nitrogen deficiency resembles,
and could easily be mistaken for manganese
deficiency.
On some of the sandy/gravely knolls in Anne Arundel
and Prince George’s Counties that have a low Cation
Exchange Capacity (CEC) a lime application may
increase the pH to dramatically when rate of application
is based upon the predominate field silt or sandy loam.
Is the soil sandy or gravely at the yellowing area?
What is the pH at this particular field site verses the
entire field?
Unfortunately, complete soil sampling at the time of this
examination may not be practical due to the urgent
need for corrective action in order to offset yield loss. I
would suggest the use of a pH test kit to rapidly
compare the affected site to an area where the
soybeans appear to be growing normally.
Manganese is most available between the pH range of
5.0 to 6.5, yet, soybean rhizobium nodulation and Nfixation is more active at a pH range of 6.5 to 7.2,
posing a bit of a pH balancing dilemma.
Manganese is a minor nutrient essential in the activation
of many plant enzymes, and is also a critical element in
the chlorophyll photosynthesis electron transport
process, hence the yellowing.
An accurate, and fast in field pH determination is best
done with a wet chemistry testing kit. La Motte Soil
Testing Products located in Chestertown, Maryland offer
an excellent pH testing kit.
Manganese deficiency is characterized by uniform
yellowing of the younger leaves, with the veins
remaining green.
For a free copy of La Motte’s Soil Testing Catalog call
800 344-3100, or access their website at:
www.Lamotte.com
The symptoms are more pronounced during cooler than
normal growing conditions, and fields may overcome
early deficiency symptoms as the soil warms.
If the soil pH is above 6.8, and all other previously
discussed causal agents for soybean yellowing other
than manganese have been ruled out, then foliar apply
the manganese sulfate 4 lb/acre.
Manganese symptoms detected early in the season can
be treated with a foliar fertilization spray of manganese

This is the University of Maryland Late Blight Potato Advisory for June 24, 2014.
The first late blight fungicide application is recommended once 18 DSV’s accumulate from green row. Green row is
estimated to occur in the first week of May for much of Maryland. The table below uses May 4 as the estimate of green
row for all locations except Oakland, where green row was estimated to be May 14. We have exceeded the threshold of
18 DSV’s in most locations except Oakland. A protectant fungicide such as mancozeb or chlorothalonil should be
applied. No late blight has been reported in the region in 2014. However, continue to examine plants for signs of late
blight.
Continue to scout fields thoroughly. Late blight was reported on potato in eastern North Carolina on June 19, and on
Long Island, New York or June 20. For more details see http://www.usablight.org/

Washington, June 16, 2014 -- The United States
Department of Agriculture’s Animal and Plant Health
Inspection Service (APHIS) today issued a conditional
license to Harrisvaccines, Inc. of Ames, Iowa for a
vaccine that may aid in the control of porcine epidemic
diarrhea virus (PEDv) in swine. This is the first licensed
vaccine for PEDv. It will be used to vaccinate sows with
the intent that they build antibody, and transmit that
antibody through their milk to newborn piglets. It is
intended to protect the piglets against PEDv.
APHIS licenses veterinary biologics products for use in
controlling diseases of animals. Conditional licenses are
issued based on full safety, purity testing, and an
expectation of efficacy. Preliminary studies have been
promising, and they’ve shown sufficient data that we
think the vaccine will be effective. The company will
continue working toward completing the requirements
for a full license. In the meantime, there are no
restrictions on vaccine use under the conditional license.

APHIS supports and encourages the rapid development
of new vaccines, particularly in emergency situations.

When a company obtains a conditional license they are
able to bring an important disease management tool to
producers safely and quickly. Full licensing can occur
subsequently while producers get the products they
need to protect animal health.
EPA is Advancing Pollinator Science
and Sharing Useful Information with
Growers and Beekeepers
Porcine epidemic diarrhea is a disease that causes
significant sickness in swine, affecting their growth and
health, and causes high mortality in piglets. The disease
is common in parts of Asia and Europe, but is not
reportable to the World Organization for Animal Health
(OIE). PEDv only affects pigs and does not pose any risk
to people or pets. It is not a food safety concern.
On June 20, 2014, President Obama issued a directive to
federal agencies to create a federal strategy to promote
honey bee and other pollinator health. The President’s
directive created a Pollinator Health Task Force, cochaired by EPA and USDA, and charged federal agencies
with expanding federal efforts and taking new steps to
reverse pollinator losses. Scientists believe that honey
bee losses are likely caused by multiple stressors,
including poor bee nutrition, loss of forage lands,
parasites, pathogens, and pesticides. EPA will address
the role of pesticides and take action, as appropriate, to
protect pollinators. Read President Obama's directive.
Licensing this vaccine is another step APHIS is taking to
continue to help industry/producers.
Recently APHIS announced the availability of $26.2
million in funding to combat these diseases and issued a
Federal Order requiring the reporting of new detections
of PEDv and other new swine enteric coronavirus
disease to APHIS or State animal health officials. The
Federal Order also requires that operations reporting
these viruses work with their veterinarian or USDA or
State animal health officials to develop and implement a
reasonable management plan to address the detected
virus and prevent its spread. Plans will be based on
industry-recommended best practices, and include
disease monitoring through testing and biosecurity
measures. These steps will help to reduce virus shed in
affected animals, prevent further spread of the disease,
and enable continued movement of animals for
production and processing.
Two important tools are being released today as part of
EPA’s ongoing actions to protect pollinators. These and
other EPA pollinator protection efforts complement those
of the USDA, the lead federal agency tasked with
identifying and mitigating the causes of U.S. honey bee
decline.
EPA's New Pollinator Risk Assessment
Guidance: EPA has posted its new Pollinator Risk
Assessment Guidance online. The guidance is part of a
long-term strategy to advance the science of assessing
the risks posed by pesticides to bees, giving risk
managers the means to further improve pollinator
protection in our regulatory decisions. Among other
things, EPA anticipates the guidance will allow the
agency to assess effects from systemic pesticides
quantitatively on individual bees as well as on bee
colonies. The guidance, developed in cooperation with
the California Department of Pesticide Regulation and
Health Canada’s Pest Management Regulatory agency,
builds upon our ongoing efforts to advance the science
of pollinator risk assessment.
Throughout the PEDv outbreak, APHIS has worked
closely with the swine industry to identify risk factors in
the transmission of the virus and minimize its impact on
producers and industry.
APHIS is part of a task force with the Food and Drug
Administration and State and industry stakeholders,
including the American Association of Swine
Veterinarians (AASV), National Pork Producers Council
(NPPC), National Pork Board (NPB), veterinary diagnostic
laboratories (VDLs), and State Animal Health Officials
(SAHOs). This task force aims to investigate the virus,
identify and trace risk factors in the transmission of the
disease, and keep producers informed.
We are already implementing elements of the guidance
in our ongoing registration review of neonicotinoid
pesticides as well as in our other pesticide regulatory
work. The agency is currently reviewing new data we
required of the registrants, including refined semi-field
studies under more real-world application conditions.
Other data from ongoing full-field studies will take up to
several years to complete.

to pesticides sprayed on flowering plants, but pesticide
residues generally decrease in toxicity as the spray dries
and time passes. Farmers and beekeepers can use EPA's

RT25 data to gauge the amount of time after application

under real-world conditions to kill 25 percent of bees
that are exposed to residues on treated plant surfaces.
Some have used this information to select pesticide
products with shorter periods in which the chemicals
remain active and can affect bees.
Consistent with the recently released National Climate
Assessment, this report presents clear evidence that the
impacts of climate change are already occurring across
the United States. The report shows evidence that:
• Average temperatures have risen across the
contiguous 48 states since 1901, with an increased
rate of warming over the past 30 years. Seven of
the top 10 warmest years on record have occurred
since 1998.
Notice of Recent EPA Approval of
Maryland Section 18
• Tropical storm activity in the Atlantic Ocean, the
Caribbean, and the Gulf of Mexico has increased
during the past 20 years.
The US Environmental Protection Agency just approved
the Maryland Department of Agriculture's Section 18
request to allow the use of three Bifenthrin products to
control the Brown marmorated stink bugs
on apples, peaches and nectarines.
• Along the U.S. coastline, sea level has risen the
most along the Mid-Atlantic coast and parts of the
Gulf Coast, where some stations registered increases
of more than 8 inches between 1960 and 2013.
• Glaciers have been melting at an accelerated rate
over the past decade. The resulting loss of ice has
contributed to the observed rise in sea level.
See the attached Notice that details
the requirements for use of these 3
products under this exemption.
• Every part of the Southwest experienced higher
average temperatures between 2000 and 2013 than
the long-term average dating back to 1895. Some
areas were nearly 2 degrees F warmer than
average.
EPA Report Shows Impact of
Changing Climate on Americans’
Health and Environment
• Since 1983, the United States has had an average of
72,000 recorded wildfires per year. Of the 10 years
with the largest acreage burned, nine have occurred
since 2000, with many of the largest increases
occurring in western states.
• Water levels in most of the Great Lakes have
declined in the last few decades.
WASHINGTON – Today, the U.S. Environmental
Protection Agency (EPA) released the third edition of a
report, Climate Change Indicators in the United States.
The report pulls together observed data on key
measures of our environment, including U.S. and global
temperature and precipitation, ocean heat and ocean
acidity, sea level, length of growing season, and many
others. With 30 indicators that include over 80 maps and
graphs showing long-term trends, the report
demonstrates that climate change is already affecting
our environment and our society.
The report also looks at some of the ways that climate
change may affect human health and society using key
indicators related to Lyme disease incidence, heatrelated deaths, and ragweed pollen season. For
example, unusually hot summer temperatures have
become more common which can lead to increased risk
of heat-related deaths and illness. Warmer temperatures
and later fall frosts also allow ragweed plants to produce
pollen later into the year, potentially prolonging allergy
season for millions of people.
“These indicators make it clear that climate change is a
serious problem and is happening now here in the U.S.
and around the world,” said Janet McCabe, acting
assistant administrator for EPA’s Office of Air and
Radiation. “Everything we do to reduce greenhouse gas
emissions and prepare for the changes that are already
underway will help us safeguard our children’s future.”
EPA compiles decades of observed data in cooperation
with a range of federal government agencies,
nongovernmental organizations, universities, and other
institutions. The Indicators report focuses on long-term
trends for key measures of our environment for which
high-quality data exist. Each indicator and the report
itself were peer-reviewed by independent experts, and
extensive technical documentation accompanies the
report.
The third edition of the Indicators report, which was last
published in 2012, adds additional years of data and
four new indicators: Lyme disease, heating and cooling
degree days, wildfires, and water level and temperature
in the Great Lakes. In addition, the report adds four new
features that connect observed data records to local
communities and areas of interest, including cherry
blossom bloom dates in Washington D.C., timing of ice
breakup in two Alaskan rivers, temperature and drought
in the Southwest, and land loss along the mid-Atlantic
coast.
