To produce growers in Johnston County

Cucurbit Downy Mildew has been confirmed in Johnston County as of Friday (06/26/15) in 3 separate locations. On earlier planted crops that have already been picked several times this may not cause any concern as the heat and dry weather the last 2 weeks have aided in expiring the plants a little quicker than hoped. But on later planted crops that may not have been picked yet or are just starting to produce this could cause some potential concern. With the rain and cooler temperatures over the weekend the conditions are excellent for downy mildew to spread so a preventative fungicide spray is recommended if you have not done so already. This could help prolong the later planted crops and aid in producing a marketable product. If you have any questions or concerns please contact Brandon Parker with the Extension service.

Gavel, Bravo, Zampro, Tanos and Previcur FLex are all listed as FAIR products for downy mildew control and Ranman is listed as GOOD for downy control in the 2015 Vegetable crop handbook. Also Previcur Flex can be tank mixed with the other fungicides to help provide greater protection.

Carpenter Bees and their Control

With warming temperatures our hovering neighbor the “Carpenter Bee” is beginning to
make an appearance. These busy bees can offer quite a nuisance for homeowners with
their excessive buzzing and wood excavation. Typically, carpenter bees do not cause
serious structural damage to wood unless large numbers of bees are allowed to drill many
tunnels over successive years. The bees often eliminate their wastes before entering the
tunnel. Yellowish-brown staining from voided fecal matter may be visible on the wood
beneath the hole as seen in the picture above. Woodpeckers may damage infested wood
in search of bee larvae in the tunnels. In the case of thin wood, such as siding, this
damage can be severe. Holes on exposed surfaces may lead to damage by wood-decaying fungi or attack by other insects, such as carpenter ants.
Although carpenter bees resemble bumble bees, the two can be readily distinguished
from one another, as carpenter bees lack the yellowish hairs on their abdomens
(which are black and shiny). The male bees are easy to identify because they have
white spots in the center of their head (between their eyes), and they are typically
seen hovering around prime real estate watching for the girl bee of their dreams
and chasing off rival males at the same time. Male bees do not sting but their
aggressive behavior can be intimidating to those passing by.
After mating, the female bee goes hunting for a new place to build a nesting
gallery. Choice locations will be wooden porch rails and balusters, wooden planks and
solid wood siding. This includes treated and resistant wood species. Females will
excavate a nearly perfectly round hole and gallery that typically follows the grain of the
wood. Females then make a ball of pollen, stick it into the gallery and deposit an egg.
She will then construct a partition of chewed wood debris and repeat this process until the
gallery is furnished with multiple offspring. At that point, the female dies and for most of
the summer, no activity is seen. The offspring will then emerge in late summer and/or fall
and hang around before finding a sheltered location to pass the winter (like an abandoned
gallery). When control is warranted, there are a couple of options. First, chasing the bees
around the yard with a badminton racquet can offer some stress relief. However,
long-term control is questionable. The second, slightly more effective option is
treating individual excavated galleries with an insecticidal dust. By treating individual galleries, you are far more likely to produce a lethal effect on these bees. Wide spread surface applications of insecticide provide little control and are often dangerous for both humans and other insects. A targeted approach will provide a slightly safer and satisfactory result. After applying an insecticidal dust to the individual gallery,
following up by placing a small ball of tin foil into the hole and apply caulk. This will
help seal the hole from moisture, and reduce overwintering sites for these insects.
Always remember when applying an insecticide to READ AND FOLLOW THE LABEL
DIRECTIONS. If you would like more information about Carpenter Bees you can visit

Wayne County joins quarantine area for emerald ash borer
RALEIGH – Wayne County is the latest to come under quarantine rules
restricting the movement of hardwood firewood, ash nursery stock and other ash
materials after emerald ash borers were confirmed in a 2.5-acre stand of trees on the
Cherry Research Farm. Agriculture Commissioner Steve Troxler signed an emergency
quarantine order allowing the expansion.
An employee with the research farm noticed unusual markings on ash trees and
contacted an entomologist with the N.C. Department of Agriculture and Consumer
Services’ Plant Industry Division for confirmation of EAB. Ash trees were planted on
about 13 acres in 2000 as part of a research project.
Granville, Person, Vance and Warren counties remain under quarantine from the
first detection of emerald ash borer in the state in June 2013. North Carolina was the 20th
state in the country to confirm the presence of the destructive pest.
“This discovery comes as our Plant Industry Division prepares to begin placing
traps, readying for beetle emergence in April. Staff will be setting out traps statewide
looking for signs of this pest in other locations,” Troxler said. “If you see the purple,
triangle-shaped traps, please do not disturb them. We ask for the public’s cooperation
with these quarantine rules to restrict the movement any further.”
The beetle was first detected in the United States in Michigan in 2002. It is
responsible for the death or decline of tens of millions of ash trees across the country.
Under the state quarantine, all hardwood firewood and plants and plant parts of the
ash tree — including living, dead, cut or fallen, green lumber, stumps, roots, branches and
composted and uncomposted chips — cannot be moved outside the county.
The Plant Industry and Research Stations divisions and N.C. Forest Service are
working in cooperation with the U.S. Department of Agriculture’s Animal and Plant
Health Inspection Service.
Symptoms of emerald ash borer in ash trees include a general decline in the
appearance of the tree, such as thinning from the top down and loss of leaves. Clumps of
shoots, also known as epicormic sprouts, emerging from the trunk of the tree and
increased woodpecker activity are other symptoms. The emerald ash borer is not the only
pest that can cause these.
Emerald ash borers overwinter as larvae. The adult beetle is one-fourth to a halfinch
long and is slender and metallic green. When the adults emerge from a tree, they
leave behind a D-shaped exit hole. The larvae can also create serpentine tunneling marks,
known as feeding galleries, which are found under the bark of the infested trees.
Home and landowners are encouraged to report any symptomatic activity in ash
trees to the NCDA&CS Plant Industry Division hotline at 1-800-206-9333 or by email at
newpest@ncagr.gov. The pest can affect any of the four types of ash trees grown in the
state.

2015 Wheat Contest

 

Anyone interested in entering the 2014/15 Wheat Yield contest should contact Tim Britton at the Cooperative Extension Office at 989-5380. Remember that you must have three acres of contiguous wheat to enter the contest.

 Corn Nitrogen Needs for Coastal Plain

 A typical nitrogen uptake curve shows that corn takes up about 15 lbs/acre of nitrogen by the time corn is about 15 inches tall. It starts a rapid uptake period at this time and will grow about 3 feet the next two weeks with good moisture and take up about 80 lbs/acre of nitrogen during those two weeks, followed by another 50 lbs/acre of uptake in the next two weeks prior to tassel emergence. Therefore, at least 130 lbs/acre of nitrogen will need to be available in the four weeks after corn reaches the 15-inch height range. Over the next 6 weeks of ear formation, corn will take up another 100–150 lbs/acre of nitrogen. However, if nitrogen is adequate until tassel emergence, no yield increase would be expected from additional nitrogen application after tassel emergence. Only grain N content is increased with N applied after tassel emergence.

USDA Local Foods Directory

USDA has developed a local food directory to help farmers who have a stand, store, or
other direct-to-consumer retail outlet on the farm to be found more easily. USDA wants
to raise awareness of this resource. Details can be found here:

Pesticide Container Rinse and Recycle Program

The pesticide container rinse and recycle program has expanded to two new locations,
giving Johnston County more room to properly dispose of pesticide containers.
These sites are located at 820 Stewart Road in Four Oaks, 1096 Scout Road in the
Bentonville area, 9349 NC Hwy 96 S in the Meadow area, 5677 US Hwy 301 in Kenly,
15031 Buffalo Road in Clayton, and at the Johnston County Landfill site on County
Home Road in Smithfield.
Properly rinsed containers can be taken to these sites during normal operating hours.
You do not need a county solid waste sticker to dispose of containers. Remember, to
remove the label and lid, on buckets, remove the label and large lid, and on 35 and 55
gallon drums, drill holes in bottom and do not crush.
