Upcoming Events
The Third Monday in July, July 17, will feature a forum on
Sustainable Hog Production and Marketing. This program
will run from 9-4pm at Wells Auditorium NCA&T in Greensboro. Presentations
will be made concerning the advantages of turning to alternative production
practices such as pasturing/grass fed, reducing stress, factors affecting the
taste of the meat and can manipulating the taste be a marketing niche?,
slaughtering options and processors, breeds suitable for pasturing, pasture
development, electric fencing, markets and marketing options (with some
upscale market buyers present), the "how-to's" on forming a cooperative for
grain purchasing and for getting into processors and markets, a field trip to
a pasture based research trial, and more. Lunch will be BBQ on locally
pastured pork. Presenters will be made up of specialists, USDA, farmers,
processors, and market buyers. Call Robert Hadad for details.
August 21, the Third Monday of the Month, will have a workshop on
COOPERATIVES: The Nuts and Bolts, Pro's and Con's of
Starting a Cooperative. This workshop will feature a cooperative
specialist from USDA Dept. of Rural Economic Development, who will go into
detailed explanation of the legalities, member responsibilities, and
everything else involved with starting a coop. Several farmer cooperative
representatives to tell their own stories on how they started a coop and what
it has meant to their marketing opportunities. This workshop will be at the
Chatham Co. Extension Center Auditorium. time to be announced. Call Robert
Hadad for details.
Nitrogen: Apply 25-50lbs of actual N/A preplant. The rate will vary based on cropping
history of the field and
general fertility of the soil. If following a sod cover crop, apply 50lbs N/A. After fruit begin
to form, sidedress
with another 50lb of N/A. Two weeks later add another 50lbs/A.

Harvest
Post Harvest
Insects
Aphids can be treated with insecticidal soaps or trapped with yellow sticky traps.
Biological controls can also be
an option for long term control if aphids are a persistent problem. Aphidiid wasps, lady
beetles, lacewings.
Beet armyworm appears sporadically. The moth is blown in from the cotton belt of
the South. Voracious eaters,
the most effective treatment is to use a neem product when the larvae is young. This insect is
tolerant to most
insecticides.
Cutworms can be managed by eliminating weedy areas. Early spring tillage can cut
down populations by
exposing them to the surface and disturbing their food source and egg laying sites.
Flea beetles may be managed by eliminating overwintering sites. Rotation around
the field, staying away from
field margin areas. Intercropping, with many smaller plots of greens rather than a large plot
will be effective in
reducing pest population damage. Spring time may be the worst time for flea beetles in some
years. A floating
row cover with a strong, narrow spaced weave may give the best protection. Drench ground
with parasitic
nematodes early in the season to build up populations to battle the generation of flea beetles
that emerge from
the soil around crops.
European corn borer is a key pest of peppers. Use monitoring traps to scout for first
migrating adults. Use Bt
products for control. Begin applications when trap catches at least 10 moths/week.
Spider mites can build up in population and can be treated with insecticidal soap or oil.
Attracting beneficials to
the area with wild flower plantings or release predatory mites into the leaf canopy can reduce
populations.
Stinkbugs can be control with a light application of insecticidal oil. Braconid wasps
attracted to the area could
help keep populations of stinkbugs lower.
Diseases
Anthracnose, Cercospora leaf spot, Alternaria fruit rot problems can be reduced
through rotations of 3-4 years in
crops not related to peppers. Anthracnose, Cercospora Leaf Spot, Alternaria Fruit Rot,
Anthracnose occurs as
sunken spots on green and ripe fruits, accompanied by pinkish spore masses in wet conditions.
Cercospora leaf
spot develops during prolonged periods of hot, wet weather, as large circular to oblong spots,
usually with a
white to gray center. Alternaria develops as a black mass of spores on damaged areas of the
fruits. Controlling
weeds, especially solanaceous weedy species will help in eliminating alternative hosts for
these diseases. Copper
dusts can be used sparingly but not in hot humid weather.
Bacterial soft rot Effective control of insects will aid in controlling the spread of
this disease. Sanitation is
important in destroying any rotting fruit found in the field. Bacterial soft rot causes a very
soft slimy rot with a
strong odor. The bacteria causing it are commonly present on the fruit surface and enter the
fruit through
wounds, especially those near the stem end. Control insect pests (especially corn borers) and
spotting diseases to
minimize wounding. If wash water is used in packing operations, it should contain 25 ppm of
available chlorine.
A number of chlorine sources are available, but for most small operations the most available
option is to use
household bleach (those containing 5.25% sodium chlorite) at the rate of 1 Tablespoon of
bleach per 8 gallons of
water or 1 pt/264 gallons of water. To keep the chlorine available, it is important that the
initial water pH be 6.0
to 7.5, that the water remain clean and changed often, and that the water temperature be near
the temperature of
the fruit (no colder than 10ø below that of the harvested fruit).
Bacterial leaf spot Bacterial Spot (Part I of II) See next frame below Bacterial leaf
spot occurs as water-soaked,
black to tan, irregular shaped spots on the leaf, especially the margins, and on fruits as raised
spots. Defoliation
of infected leaves can be extensive, greatly impacting fruit quality. This disease can be a
limiting factor to the
economic production of peppers because the weather is often ideal for bacterial spot
development and control
options are marginal. Several breeding programs in the US are working on this problem and
resistance genes
have been moved into horticulturally acceptable cultivars. Preliminary cultivar testing shows
considerable
promise. The bacterium causing this disease is seed borne, transplant borne, and overwinters
on site and nearby
in weeds and residues. Once it is introduced into the planting and under prolonged wet
conditions, control is
limited because of the rapid rate of reproduction and limitation of available chemicals.
THEREFORE,
CONTROL IS CENTERED AROUND PREVENTING INTRODUCTION OF THE
BACTERIUM RATHER
THAN ERADICATION OF IT ONCE PRESENT!
Use crop rotations of 2 to 3 years, excluding peppers, tomatoes, and tobacco for the total
rotation plus also
exclude small grains in the regime the season before peppers are to be planted. Control
broadleaf weeds during
the rotation and around the field borders. Disk all crop residues into the soil promptly after
harvest to encourage
more rapid decline of the bacterium and plow cover crops very early in the spring to
minimize carry-over. Do
not work plantings while wet. Spraying plants while wet with high pressure may encourage
spread by blowing
bacteria about the field. Resistant varieties of fresh market peppers are available and should be
utilized in areas
where bacterial spot is frequently a problem. Use western-grown, disease-free seed whenever
possible and treat
them before planting with household bleach (2 pts household bleach to 1gallon of water per lb
of seed, washing
for 40 minutes with continuous agitation). For greenhouse production of transplants, copper
can be used as long
as the temperature is not hot and humidity is low. If you buy transplants, assume there is
some bacterium in
there. Feed transplants with high N and K. Highly fertilized plants are somewhat less
susceptible to leaf spot
than nutrient deficient ones. Copper sprayed on plants early in the season seem to keep
bacterium populations at
low levels. Use once every week during wet periods to reduce any buildup and spread of the
leaf spot in the
field.
Blossom end rot is not an infectious disease but is caused by calcium deficiency.
Poor soil moisture can also
restrict calcium uptake in the plant.
Phytophthora blight is similar to tobacco black shank but form different fungi. Soil
drainage is critical for
controlling this disease. Raised beds aids in this nicely. Rotation with non-solonaceous and
non-cucurbit type
crops.
Southern stem blight Plants wilt and die due to girdling of the stem by this fungus.
Signs of the fungus include
a white mold and small sclerotia (resemble mustard seeds). This disease is often found in lots
of transplants, so
set clean plants. Avoid fields with a history of this disease and rotate problem fields with sod
crops. Sclerotinia
has a wide host range and is common on tobacco, soybeans, peppers, and tomatoes. Deep
plow to bury sclerotia
and crop debris. Incorporate cover crops early to ensure they are well rotted before
transplanting into the site.
Maintain good weed and grass control through preventative means because the fungus can
attack dying weeds
then move onto pepper transplants. Eliminate weeds and grass from around fields since this
fungus attacks dying
weeds then moves to peppers.
Tomato spotted wilt This virus disease is carried by thrips and can cause serious
losses when introduced into
young plants, especially if in the transplants. Ensure that transplants are from fields or
greenhouses certified to
be free of TSWV. Local transplant producers should take steps to reduce spread of TSWV by
following
recommended thrips control and not producing pepper transplants in houses where
ornamentals are being
produced or sold. Rogue out infected plants as soon as they are found and maintain a thrips
control program.
Virus complex Tobacco etch, potato virus Y, alfalfa mosaic virus, tobacco mosaic,
and cucumber mosaic are the
viruses are common in peppers. Except for tobacco mosaic virus, all are aphid-borne from
infected plants
(weeds, tobacco and other sources), but the application of insecticides is not the key to
control. Grow varieties
with resistance where acceptable horticulturally. In addition to the recommended varieties
listed earlier in this
section, Gator Belle, Bell Boy, Bell Captain, Super Sweet 860 are resistant to tobacco mosaic
and Tam Mild
Chile-2 has resistance to tobacco mosaic, potato virus Y and etch. Eliminate broadleaf weeds
and other sources
of these viruses within 150 ft of planting before transplanting. This can be done by locating
fields between
plantings of corn or other non-host, field crops where the weeds are killed before peppers are
transplanted. Do
not grow peppers within 150 ft of tobacco. Controlling aphids in tobacco located near
peppers, especially at the
time of tobacco harvest, helps to reduce movement of aphids and viruses to peppers. Recent
surveys indicate that
growing tobacco varieties resistant to the aphid-borne virus complex may be helpful in
reducing these diseases in
peppers, probably because the pathogen level in the nearby community is greatly reduced.
Maintain aphid control
in peppers. In problem fields, with a high value fresh market crop, spraying weekly with
stylet oils can be
helpful (using 3 qt/100 gallons) [see labels and follow the labeled protocol strictly], but the
value of this
treatment has not been evaluated. Reflective mulches show promise in reducing the incidence
of these diseases.
Powdery mildew can be treated with sulfur at the first appearance of the diseases. Be sure to
monitor
temperatures. Applying sulfur when air temperature moves much above 80 degrees will cause
leaf burn.
A word about weeds. If growing peppers on raised beds, using a living mulch
between the beds is a good
deterrent for weeds. A low growing, thickly sown crop such as dwarf white clover,
subterranean clover, or rye
can be grown. If cover crops get tall, mowing is an easy option (be sure your beds are spread
far enough apart to
allow for mower to get in).
