Field Observations from
Southern Maryland

bbeale@umd.edu
9 Scattered showers have helped crop conditions. Rains
have been sporadic, with some areas receiving a total
of several inches and others less than a half of an
inch. Harvest of summer crops continues well. Many
farmers are beginning to plant fall brassica crops.
9 Squash vine borer is prevalent in some pumpkin and
squash fields, and spider mites are present in many
fields, so scouting is highly recommended. Corn ear
worm pressure is increasing in sweet corn fields.
9 Powdery mildew has really ramped up in the last two
weeks in cucurbit and fruit crops.

Plasticulture Strawberries
Planting will begin in September. Depending on your
location, the optimum time for planting the variety
Chandler can vary by several weeks. Because we cannot
predict with any certainty what the 2012 fall and 2013
winter temperatures may be, some folks will stagger
their planting dates over several weeks.
If this variety is planted too early in September and
we have a mild fall, plants can make too many crowns
resulting in smaller berry size and producing many fall
runners. If we plant in late September and we have a
cool fall, we can utilize a floating row cover to increase
fall plant growth. My Chandlers will be ready to plant the
week of September 17th and I have a 1.2 ounce floating
cover ready to deploy if needed later this fall.
Volume 3 Issue 9 August 16, 2012
Here are a few key points to note prior to preparing the
field for bed shaping and laying the plastic:
9 Soil sampling for nutrient analysis.
9 Work down cover crops in a timely manner so
preparing the raised bed in time for planting is not
compromised.
9 Adjust soil pH to 6.0-6.2.
9 Adjust phosphorous, potassium, magnesium and
micronutrients based on soil analysis.
9 On very sandy soils, additional sulfur and boron should
be applied.
9 One-half to two-thirds of the total nitrogen
requirement should be applied before bed shaping,
with the remainder applied in the spring.
9 If manure or other organic fertility inputs are used,
apply these at rates needed to supply nitrogen to the
strawberry crop. When using organic inputs for
fertility, proceed with caution in the spring with
additional nutrient needs. Always use leaf and petiole
analysis to gage plant nutritional needs.
9 If using a soil fumigant, be sure to allow enough time
(follow the label or use a lettuce seed test) for the
fumigant to dissipate before planting.
If you are attempting to carry-over a Plasticulture
planting of Chandlers, you should have mowed the
leaves off after final harvest, kept the plants alive with
minimal watering and maintained insect and disease
control. If you had any Anthracnose, you should
not be carrying-over this field! Disease pressure
in general can be greater in carry-over fields.
Starting in early September, the crowns need to be
thinned back to 2 -3 crowns per plant. If this crown
thinning is not done, spring fruit size will be small.
After crown thinning, begin fertigation with 20-30 lbs.
of nitrogen per acre. Since there is most likely residual
fertility in the beds, spring leaf and petiole sampling
will be necessary to gauge additional fertility inputs
beginning shortly after first new leaves emerge.

reminder, Orthene (acephate) will not provide effective
corn earworm control in processing snap beans. If
Orthene is used for corn borer control you will need to
combine it with a material that is effective on corn

Important Note – This is the time of year when we see
significant increases in trap catches so be sure to check trap
catches in your area. You can get updates by calling the Crop

Once pins are present on fresh market snap beans, a 7day schedule should be maintained for corn borer and
corn earworm control.
Cole Crops
Continue to sample for cabbage looper, diamondback
larvae, armyworms and Harlequin bug. Although the
pyrethroids will provide control of Harlequin bugs they
are not effective on diamondback. So be sure to scout
and select controls options based on the complex of
insects present in the field.
Sweet Corn
The first silk sprays will be needed as soon as ear
shanks are visible. Be sure to check both blacklight and
pheromone trap catches for silk spray schedules since
the spray schedules can quickly change. Trap catches
are generally updated on Tuesday and Friday mornings
at: http://ag.udel.edu/extension/IPM/traps/latestblt.html
and
Lima Beans
Continue to scout for spider mites, stink bugs and lygus
bugs. Be sure to sample for corn earworm larvae as
soon as pin pods are present. A treatment will be
needed if you find one corn earworm larvae per 6 ft-ofrow. With the increase in local corn earworm catches we
are starting to see an increase in larval populations.

You can also call the Crop Pest Hotline in state: 1-800345-7544; out of state: 302-831-8851.
A whorl stage treatment should be considered for fall
armyworm when 12-15% of the plants are infested. We
continue to find pockets of high fall armyworm
infestations. Since fall armyworm feed deep in the
whorls, sprays should be directed into the whorls and
multiple applications are often needed to achieve
control. Be sure to check all labels for days to harvest
and maximum amount allowed per acre.
Melons
Continue to scout all melons for aphids, cucumber
beetles, and spider mites. We continue to see an
increase in aphid populations. Treatments should be
applied before populations explode and leaf curling
occurs.
Peppers
In areas where corn borers are being caught in local
traps, fields should be sprayed on a 7-day schedule for
corn borer control. As soon as corn borer trap catches
increase to above 10 per night, a 5 to 7-day schedule
may be needed. Since trap catches can increase quickly
at this time of year, be sure to check local moth catches
in your area by calling the Crop Pest Hotline in state: 1800-345-7544; out of state: 302-831-8851 or visiting our

Stink Bugs Bad in
Some Tomato Fields But it is Not BMSB
By Jerry Brust, IPM Vegetable
Specialist
University of Maryland
jbrust@umd.edu
http://ag.udel.edu/extension/IPM/traps/latestblt.html
We continue to find beet armyworms (BAW) so be sure
to watch for feeding signs and apply treatments before
significant webbing occurs. We continue to find aphids in
fields and populations can explode quickly, especially
where beneficial insect activity is low. As a general
guideline, treatment may be needed if you find one or
more aphids per leaf and beneficial activity is low.
I have seen a great deal of stink bug damage to
tomato fruit this year-more than usual (fig 1). The fruit
has the characteristic white spots that when peeled back
reveal spongy white areas. As the fruit turns red these
white areas turn yellow (fig 1). When adults or especially
nymphs feed on the fruit they create a star burst pattern
in the surface of the fruit. I guess the surprise is that I
have found very few if any Brown marmorated stink
bugs (BMSB) in any of these tomato fields. Almost all of
the stink bugs have been brown stink bugs (Euschistus
spp), although lately (last 2 weeks) I have seen more
green stink bugs. There have been very few reports or
observations of BMSB being much of a problem so far
this year in vegetables. Adult brown stink bugs are
Snap Beans
At this time of year, you will need to consider a
treatment for both corn borer and corn earworms.
Sprays are needed at the bud and pin stages on
processing beans for corn borer control. An earworm
spray will also be needed at the pin stage. Just as a

grayish-yellow to light brown with dark punctures on
their back (fig 2). They DO NOT have two white spots
on their antenna as do BMSB.
Adults overwinter in woods, fence rows and under the
bark of trees. A female oviposits a total of about 60 eggs
over the summer. The nymphs, which are pale green,
develop through five instars and require about one
month for development. Because the adults are strong
fliers they rapidly can move between hosts.
Brown stink bugs are very difficult to scout for and
often the only thing that is seen is the damage they
cause to large green or ripening fruit. Some of the most
heavily fed upon fruit had very dark areas that when cut
into appear as a dry rot (fig 3). What microorganisms
are in this dry rot area is something we are looking into.
It appears that our native stink bugs can inject
organisms almost as readily as do BMSB when they
feed.

This has been a very hot dry summer so far and we
would expect to see pests such as twospotted spider
mites and their damage to be common, which we have.
However, I have been surprised by the amount of worm
(Lepidoptera larvae) damage in tomatoes. Usually
worms are a problem in a few fields every summer
where they do some damage, but the amount of
damage they have done in some fields this year is much
greater, around 15-20% of harvestable fruit in several
instances.
The biggest culprit seems to be yellow striped
armyworm (YSAW) Spodoptera ornithogalli (Fig. 1). As
the name implies the larvae have two bright yellow
stripes on the upper part of the worm running the length
of its body. The yellow stripe is often flanked towards
the inside with black triangular-shaped markings. This
worm species tends to feed on the foliage of many
plants, but most of the damage I have seen this summer
has been on the fruit with little feeding on the foliage.
The fruit damage usually appears as surface feeding
(Fig. 1) or feeding holes that are very shallow and do
not penetrate too deeply into the fruit (Fig. 2). This
often leads to a dry type of damage as opposed to the
smaller, deeper holes that often lead to a wet rot (Fig.
2).
The YSAW overwinters as pupa in the soil and
becomes active in late May or mid-June in our area. This
year it has become active much earlier than it normally
does and has built its population earlier too. We usually
do not see this much damage until late August.
Management must take place early when larvae are
small; once larvae become large they are difficult to
control.

reveal spongy white cells.

Figure 2. Yellow striped AW damage to ripening tomato fruit.
Dry (yellow arrows) and wet damage.
Figure 4. Tomato pedicels and blossoms with bacterial spot.
Another surprise is that bacterial diseases are turning
up in many tomato fields. Moist weather and splashing
rains are most often needed for spreading bacteria.
Maybe the presence of bacteria in the field is not too
surprising, but what is surprising is the widespread
nature of the bacterial spot, speck and sometimes
canker diseases.
Most tomato fields I have looked at in the last two
weeks seem to have at least some if not a considerable
amount of bacterial disease, usually on the lower leaves
(Fig. 3) that in some cases has moved up to the pedicels
of the fruit (Fig. 4). Infection of the flower or pedicel
with bacterial spot is serious, causing early blossom drop
(Fig. 5). From the pedicel the next stop for the bacteria,
after a heavy thundershower, will be the fruit.
A weekly mixture of mancozeb plus fixed copper or
ManKocide should help with bacterial spot or speck, but
once in the field, bacterial diseases are difficult to
control. If a grower has an older tomato field that has
bacterial spot in it that field should be plowed under as
soon as possible as it will act as a nursery for spreading
the disease to the younger tomato fields.
Figure 5. Blossom drop due to bacterial infection (yellow
arrows) and the start of a flower being aborted (red arrow).
The last ‘surprise’ pest has been the seemingly sudden
appearance of downy mildew in cucumber fields (Fig. 6).
This disease usually needs cooler weather that we have
had little of this summer. But on July 21st we had a cool
wet period when several areas in the mid-Atlantic set a
record low for the daily high (77o F). Right after this brief
cool down the downy mildew seemed to explode.
Many of the cucumber fields I visited in southern and
central Maryland that had been harvested at least once
had downy mildew. Once it starts it can defoliate a patch
of cucumbers very quickly leaving any fruit to sunburn
(Fig. 7).

There are several fungicides registered for managing
downy mildew. The “targeted” products below should
all be used in a tank mix with protectant product such as
chlorothalonil or mancozeb. (These products are not
effective on powdery mildew, so remember to include a
product to control powdery mildew, also.)

Downy mildew on pumpkin and butternut squash is
now present in many fields in Maryland and Delaware.
Growers should scout their fields carefully. Preventative
sprays are more effective than fungicides applied after
the disease is established. On the lower surface the
lesions are brown and angular. If viewed through a good
hand lens, black flecks, which are the sporangia, may be
visible. On the upper surface of the leaves the
symptoms are more general and mimic many other
diseases. Lesions on the upper surface appear as yellow
angular spots that eventually turn brown and necrotic.
Also, be aware that powdery mildew is also be abundant
in a fields. Powdery mildew will appear as white granular
spots, and are prevalent on the leaves below.

BMSB & SWD Update for
Central Maryland
By Bryan Butler
Senior Agent, Carroll County & MidMaryland Tree Fruit Agent, UME
It has seemed this season that BMSB has been
looming on the borders and in wooded areas since June.
Every once in a while they seem to be moving into
orchards and other crops. Monitoring the perimeters has
shown some fairly large numbers in corn and an
increased interest in soybeans but damage has not
appeared to be significant in horticultural crops that are
being well managed.
As we move into the end of the 2012 season and as
the number of crops in the field begin to decrease, it is
important to remember BMSB numbers tended to
increase in the 2008-2010 seasons and 2012 could be
following the same trend. That could mean trouble for
late crops. We have seen increasing BMSB captures in
light traps and baited pyramid traps in many locations.
In addition, bugs have been found in orchard blocks
near woodlots in one location – likely moving in from
wild hosts. At WMREC numbers in fall raspberries and
apples are definitely on the rise.
This information is presented simply to encourage
everyone to be vigilant in terms of scouting, especially
considering the value of the apple crop this year.
As far as SWD this pest appears to have become
ubiquitous where we have been sampling. Based on last
year’s monitoring numbers will continue to increase

through the late fall. It will be important to keep a close
eye on blackberries and fall raspberries the remainder of
the season. Any attempts at increased sanitation in the
fields will certainly be useful but a seven day spray
schedule is probably more practical in pick your own
situations.
There is no question this is a pest that we will have to
deal with in the long term and it certainly does not make
any of our lives easier. However, I do not think this is
going to be catastrophic to soft fruit production. I feel
this way because I have observed this season when
SWD has appeared to flare up in fruit, that after closely
examining the circumstances there have been reasons
that predisposed the crop to infestation i.e. absence of
insecticides or allowing the crop to overrippen, and
when the larva in the fruit were reared out, many of
them were not SWD but rather other fruit flies that have
been around a long time. I have also had to dissect fruit
to look more closely than I ever have before to find the
larva in the fruit and wonder if there have been a certain
number of fruit fly larva in the fruit in seasons past that
went undiagnosed.

To Weigh or Not to Weigh
I recently took a call from a vegetable produc‐
er who operates a roadside stand. He was
selling very large tomatoes and was having
trouble pricing them. His standard sales meth‐
od was to fill a quart container with tomatoes
and price them by the container. But he found
these large tomatoes didn’t work well in his
model. I suggested selling them by the piece
or be er yet, by the pound. He was reluctant
to use a scale because it took me to weigh
the veggies and then calculate the price. Also,
he didn’t want to have to make exact change.
Retail sale of fruits, vegetables, and other
items is regulated by the Maryland COMAR.
Vendors may erroneously believe that they are
exempt from these regula ons because they
sell rela vely li le compared to a supermarket
or because they only sell for a few months of
the year. Most businesses are to some degree
affected by weights and measures laws. This
will vary on the type of business. In general, if
you will be using any type of weighing and
measuring device (scale, gas pump, and meter)
you will be directly affected. If you will be
packaging commodi es you will need to
know packaging, labeling, and net quan ty
requirements. The regula on was established
to ensure that buyers receive sufficient and
accurate informa on with which to compare
quan ty and price. Even if you sell by count,
“three ears of corn for $1,” for example,
compliance with the Weights and Measures
is necessary. As a vendor, complying with the
regula ons protects you from percep ons of
shortchanging customers or misrepresen ng
your product.

made available using several different types
of containers or measures. These container
sizes may not convert directly to common

measures are required at all mes when selling to
consumers at farmers’ markets, roadside stands,
or other commercial outlets. Produce may be sold
by weight, count, or measure. For example:
Direct sale by weight: Apples: 50¢ per pound
By weight in prepackaged form: 2‐pound package
for $2 per package
By count: Apples: 6 for $1; Watermelon: $3 each
By measure: Strawberries: $2 per dry quart
and 4.61 pounds respec vely for a total of 22.50
pounds. Priced at $3.75 per pound, the net sale
would be $84.38.
Purchasing and Maintaining Legal Trade
Produce Scales:

While selling at a farmers’ market, it’s o en more
expedient to price items so that when people pay,
making change is quick and easy to deal with the
rapid flow of customers. But if you’re not using a
scale in your roadside stand or farm market, you
may be leaving money on the table. For example:
You sell a quart container of tomatoes for $4.00.
But if you sell those same tomatoes for $1.49/
pound and the container weighs 3.00lb, that’s
$4.47, or rounded to $4.50, for the same volume
of product. Scales are par cularly important
when selling meat and poultry products by the cut
or package. If you market your free‐range broilers
by the package for $15 each, five chickens will add
$75 to your cash box. But, most meat cuts and
chickens vary in weight per package. Those same
five chickens might weigh 4.33, 4.10, 4.48, 4.98,
commercial use.

scale inspected and maintain the accuracy.

volume. Using a traceable measure—peck,
quart, labeled boxes or berry baskets. Another
method of sale is by the count. A few items
such as parsley may be sold by the bunch.
