GAPS Workshops in Henderson County

Fresh Produce Good Agricultural Practices Workshop Series

North Carolina State University and North Carolina Cooperative Extension are partnering with the Carolina Farm Stewardship Association (CFSA) to deliver workshops across the state with the aim of providing farmers with the tools to reduce food safety risks and meet market requirements.

This two-part Good Agricultural Practices (GAPs) workshop series will address how farmers of all sizes can achieve USDA GAPs certification, deliver information on principles of

fresh produce safety and on-farm hazard assessment, as well as provide assistance with creating a fresh produce farm safety plan.

The first workshop, Principles of Fresh Produce Safety and Navigating the USDA GAP Audit, takes place in a farm environment and will be based on newly developed components focused on navigating a GAPs audit. This workshop will combine classroom and on-farm instruction to provide producers with the tools needed to identify potential food safety concerns as well as strategies to minimize contamination. Participants will receive a certificate of attendance that fulfills a portion of the eligibility requirements to receive up to $600 in GAPs Cost Share assistance from CFSA.

The second workshop, Fresh Produce Safety Program and Plan Development will provide direct assistance to producers in completing a fresh produce safety plan. Attendees will leave this session with a well-developed working draft of their specific food safety plan, which becomes the framework for an audit, and can be used to demonstrate individual farm risk-reduction steps. Completion of the first workshop is a prerequisite and basic computer knowledge is required in order to receive the maximum benefit from this session. Please bring a laptop with wireless internet capability.

Organic Broccoli Workshop

Organic Broccoli Workshop and Field Day in Waynesville

There is a lot of interest in growing broccoli, especially organic broccoli, in the Carolinas right now. Whole Foods, Ingles, Amy's Kitchen and other big buyers are asking for it. Growers at some farmers markets/tailgate markets reported a shortage of it this season. Here is an opportunity for your growers to see how some broccoli varieties performed in an organic system under very challenging conditions. They will also see the varieties being developed in the big Eastern Broccoli Project (not organic, but great looking material). We are doing this in cooperation with Carolina Farm Stewardship Association and they will hold a listening session at the end about the enterprise budgets they are creating for vegetable crops.

Event: Organic Broccoli Workshop and Field Day

Date:  September 17, 2013

Time:  10:00 am to 4:00 pm (bonus listening session runs till 5:00)

Location:   Mountain Research Station, 265 Test Farm Road,  Waynesville, NC 28786-4016

Cost: $15


Are you interested in growing organic broccoli? Designed for the commercial grower, this workshop will also be of interest to the serious home gardener. We will start the morning with an organic broccoli taste test followed by presentations on the results from our participatory organic broccoli project, renowned organic grower, Pat Battle's perspective on growing organic broccoli, and the organic broccoli market situation.

After a catered lunch, we will head out to the field to rate the side shoot production on our organic broccoli trial (this is the participatory part), followed by a visit to the large Eastern Broccoli Project field trials where new breeding lines are being tested. The latter is not an organic trial, but the new varieties should be of interest to everyone. Then we will return to the building for a moderated discussion on issues related to organic broccoli production, such as how to control harlequin bugs! The workshop will end at 4:00 pm, but Carolina Farm Stewardship Association is hosting a special focus group session afterward to get some feedback from growers on their new organic enterprise budgets (see below).

Registration:

Pre-registration is required and should be done online through the CFSA online store at the following link:

Pest News for Week of August 12

FRUIT AND VEGETABLES

Pesky Blackberry Foes

Here in North Carolina, blackberry season is in full swing! For many North Carolinians, that means it is the perfect time to stock up their freezer or pull out those Ball jars and preserve some tangy blackberry jam. Blackberry season brings back sweet summertime memories of riding my bike down the road to the blackberry thicket at the edge of the woods, gorging myself with fresh, juicy berries (probably picking up a few chiggers in the process), and heading home with purple stains on my hands, face, and clothes. Whether you prefer to pick your own berries or buy a pack from the local Farmer’s Market, we can all agree that blackberries are a signature snack for a late summer’s day. Unfortunately, blackberries, like all things delicious, come with their fair share of pests and diseases that impact fruit production.

This summer, we have seen two similar but different diseases on blackberry samples: orange rust on blackberry and black raspberry and leaf and cane rust on blackberry. Orange rust is typically the more devastating disease because it can become systemic, moving from leaves into other parts of the plant. The orange rust fungus has two forms, Arthuriomyces peckianus (formerly Gymnoconia peckiana) and Gymnoconia nitens, which differ only in the number of spore stages produced. Pustules full of orange-yellow spores develop on the undersides of leaves in late May and early June. These spores are blown to healthy leaves and infect when humidity is high and leaves are wet. Heavily infected leaves may die and defoliate. Once the plant is infected, the rust fungus becomes systemic. It grows down the infected shoot, into the crown, and then can enter newly formed roots. Symptoms associated with shoot infections include proliferation of shoots, weak and spindly canes, and lack of spines on the shoots. In mid-to-late summer, brownish black pustules that contain dark teliospores develop on the undersides of lower leaves. Teliospores do not infect, but germinate to produce basidiospores that can infect new buds or shoots, or the teliospores can overwinter on leaves before producing basidiospores the following year. Infected plants remain infected throughout their lifetime and do not recover.

Orange rust does not kill the plant outright, but infected plants are completely lost to production due to their inability to produce blossoms and berries. Controlling orange rust is largely achieved through cultural practices. Plant disease-free stock plants, eradicate diseased plants and wild berries in the surrounding area, and completely remove and destroy the entire plant as soon as symptoms develop on canes or leaves. Thin healthy plants to promote air circulation and to reduce leaf wetness.

Leaf and cane rust is caused by the fungus Kuehneola uredinis. Leaf and cane rust produces yellow spores in pustules that split the bark of infected canes, causing them to become weak. The pustules can also be found on the undersides of leaves. Diseased old canes should be pruned after fruiting. Alternate-year fruiting programs can help reduce disease pressure and routine fungicide spray programs may be effective in preventing new infections. 

Care must be taken to differentiate systemic orange rust from leaf and cane rust because leaf and cane rust does not require drastic removal methods to control disease. Identification of the rust pathogen requires a microscope and considerable knowledge in rust morphology. Suspect samples should be sent to the Plant Disease and Insect Clinic for a formal diagnosis.

Tomato and Vegetable Field Day

NC State Researchers Help Farmers Improve Their Crops

Event:  Annual Tomato and Vegetable Field Day

Date and Time:  Thursday, August 8, 2013 starting at 12:30 pm

Location:  Mountain Horticultural Crops Research Station, 74 Research Drive, Mills River, NC 28759.

For More Information: Contact Jeanine Davis at Jeanine_Davis@ncsu.edu or 828-684-3562

Western North Carolina is well known for producing high quality tomatoes, sweet corn, cucumbers, peppers, and other vegetables. Agricultural scientists with NC State University provide support to these growers by developing new varieties and researching the best practices to grow safe, nutritious vegetables that can yield a profit for the farmer while protecting our mountain soil and water. To help diversify agriculture in the region, they are also exploring potential new crops such as hops for the craft breweries and medicinal herbs for the natural products industry. The field day will open with a trade show, tomato taste test, and registration.  Participants will then tour the research station on event trailers (with comfortable seats and protection from the sun). The event will conclude with a pig pickin’ at 6:00 pm at Lake Julian (about 10 minutes away). The field day will take place regardless of the weather, so dress accordingly. This is a free event sponsored by NC State University, the NC Department of Agriculture & Consumer Services, the NC Tomato Growers Association, and the industry.

Directions to the Mountain Horticultural Crops Research Station: From I-40 in Asheville, take I-26 South (Exit 46). Travel approximately 9 miles to Hwy 280 (Exit 40). Follow Hwy 280 South approximately 2 miles to Ferncliff Park Drive on the right. Turn right onto Ferncliff Park Drive (used to be Old Fanning Bridge Rd.).  At the entrance to Ferncliff Park, turn left onto Old Fanning Bridge Road. Cross the river and turn right onto Research Drive. IF THERE IS A ROAD CLOSED SIGN AT FERNCLIFF PARK DR., FOLLOW THE DIRECTIONS BELOW.

Revised temporary directions to the Mountain Horticultural Crops Research Station:  Construction of the Sierra Nevada Brewery near our facilities resulted in a temporary road closure. Old Fanning Bridge Road at Hwy NC-280 has been renamed to Ferncliff Park Drive. If that road is still closed on the Hwy NC-280 side at the time of the field day, people coming in from I-26 should follow these directions: continue south on Hwy NC-280 past Ferncliff Park Drive.  At the third light, turn right on Hwy NC-191 (Old Haywood Road).  Go several miles and turn right on Old Fanning Bridge Road.

Late July- Pest News for WNC Fruit and Vegetable Growers

FRUIT AND VEGETABLES

From: Hannah Burrack, Extension Entomologist

End of Harvest Concerns in Blueberries

As blueberry harvest nears the end in some areas of North Carolina, a few important insect related issues require some attention.  

Spotted wing drosophila in processing fruit

Rainfall makes spotted wing drosophila (SWD) management more challenging (http://strawberries.ces.ncsu.edu/2013/05/swd_in_rain/), as growers have discovered in the last two months.  As we move into the end of blueberry harvest, fruit being picked for processing is at higher risk for SWD infestation for several reasons: It is often softer than fruit picked for the fresh market and SWD prefer soft fruit (http://news.ncsu.edu/releases/wms-burrack-suzukii-2013/). Processing fruit may be harvested less frequently than fresh market fruit, increasing the time ripe berries are exposed to SWD. Finally, because processing fruit is often machine harvested, all the fruit in the field (good and bad) may be picked.

There are some strategies that growers can employ post harvest to decrease the likelihood that SWD infested fruit will be sent off for processing:

1. Hold fruit at cool temperatures. Work in our lab suggests that SWD eggs and larvae cease development at temperatures less than 41F. They will not necessarily die at cool temperatures, but they likely will not cause further damage to the fruit. The longer fruit are stored and the cooler the temperature of storage, the more likely that small SWD larvae will die. Holding fruit at cooler temperatures also give growers the added benefit of determining how significant the infestation, as large larvae will exit fruit as it cools.

2. Sort out soft fruit. Soft fruit is the most likely to be infested with SWD for two reasons – egg laying SWD are more attracted to soft fruit and blueberries become softer as SWD feed. If growers can remove soft fruit before sending fruit for processing, this will further decrease risk of infestation being present. I suspect our aggressive soft sorting standards for fresh market blueberries are one of the reasons that SWD has been a less significant issue in this crop than some other hosts.

3. Sample collection timing. When receiving fruit, processors can either collect samples before or after fruit are sorted/de-stemmed. Samples collected before fruit has been soft sorted are not necessarily representative of the status of the fruit that will be processed. Samples of fruit after chilling and sorting, prior to processing/freezing, are likely more representative.

Post harvest leafhopper treatments

Treatments to manage sharpnosed leafhopper (http://ipm.ncsu.edu/small_fruit/hopper.html) vectors of blueberry stunt disease typically begin post harvest (http://pemaruccicenter.rutgers.edu/assets/PDF/Blueberry/iSharp-nosed_Leafhopper.pdf). Blueberry stunt disease is caused by a phytoplasma, and symptoms include "bushy" growth due to short, stunted branches and yellowed leaving during the growing season which may prematurely turn red and fall off in late summer. Most importantly, plants infested with stunt-causing phytoplasma do not produce. 

Aerial applications of ULV (ultra low volume) malathion has been used in the past for leafhoppers due to effectiveness and ease of application. However, many growers have also used this material for SWD management during the season, and careful attention must be paid to label restrictions on the number of applications that can be made of materials when selecting tools to manage sharpnosed leafhopper. Application limits apply to the entire growing season, not just harvest season, so label limits on the number of applications also apply to leafhopper treatments. Application limits apply to the amount of active ingredient, not the trade names of those active ingredients. Sources for updated labels with current use restrictions include CDMS (http://www.cdms.net/Home.aspx) and Agrian (http://www.agrian.com/home/label-lookup/overview).

Alternatives to malathion that are effective against sharpnosed leafhopper include Assail (acetamiprid) and Asana (esfenvalurate).  Imidaclorprid and thiamethoxam are also options for sharpnosed leafhopper. The North Carolina Agricultural Chemicals Manual (http://ipm.ncsu.edu/agchem/agchem.html) has recommendations for the use of these materials. It's important to note, however, that all these materials pose some risks to pollinators. While blueberries are not in bloom, some of our most efficient blueberry pollinators (http://repository.lib.ncsu.edu/ir/handle/1840.16/7822) are ground nesting bees that may remain near fields after bloom. Therefore, any insecticide treatments should be timed to leafhopper flights, ideally determined through trapping, to provide maximum efficacy against target pests and limit unnecessary applications. See http://ncsmallfruitsipm.blogspot.com/2011/04/practicing-what-we-preach-implimenting.html for information on trapping and the following for images, http://ipm.ncsu.edu/small_fruit/hopper.html, to aid in sharpnosed leafhopper identification.

Cucurbit Downy Mildew Moves Towards Western North Carolina

Cucurbit downy mildew has been reported in Haywood, Polk, Ashe, Henderson and Chatham counties (http://cdm.ipmpipe.org/scripts/map.php) during this past week. Now that cucurbit downy mildew is present in several regions of North Carolina and surrounding states, it’s important that growers scout for the disease and keep up with preventive sprays to protect their crop and avoid yield loses.

If you are not familiar with cucurbit downy mildew symptoms on different cucurbits please see our previous alert (http://plantpathology.ces.ncsu.edu/2013/07/do-you-know-how-to-diagnose-cucurbit-downy-mildew-in-different-cucurbit-crops/) to assist you in diagnosing this foliar disease. If you think you have cucurbit downy mildew in your cucurbits please contact your local Extension agent (http://www.ces.ncsu.edu/local-county-center/) and send photos and/or physical samples to the Plant Disease and Insect Clinic (http://www.cals.ncsu.edu/plantpath/extension/clinic/submit-sample.html).

For more information about the disease and how to control it, see our factsheets in English and Spanish (http://projects.cals.ncsu.edu/veggiepathology/disease_factsheets). Control recommendations are also available in the cucurbit downy mildew IPM pipe website (http://cdm.ipmpipe.org/index.php), where you can also register to receive text, e-mail and/or phone alerts when new disease outbreaks are reported. We have also compiled previous cucurbit downy mildew alerts athttp://plantpathology.ces.ncsu.edu/tags/cdm/.
