Pest Alerts for Week of June 24th


Fruit and Vegetable Pest Problems 


Hello Fruit and Vegetable Growers

There are a number of pest problems showing up that you may want to keep you eyes open for and treat.  If you are in doubt or need assistance please feel free to call your local Cooperative Extension office.

Those we have seen or are getting alerts for are included below:

Potato Late Blight Alert

Late blight was found on tomatoes on the Eastern shore of Virginia on June 20, 2013. Also, the Plant Disease and Insect Clinic (http://www.cals.ncsu.edu/plantpath/extension/clinic/) at North Carolina State University also received pictures of a potato sample from Watauga County, North Carolina that appears to be infected with late blight. However, this is an unconfirmed report and we are waiting for a physical sample to verify. Potato and tomato are susceptible to this disease, and can be significantly defoliated within days if environmental conditions favor the pathogen.

Active scouting and immediate action to protect potato crops in North Carolina from late blight is recommended, since we have been experiencing wet and cool weather that is conducive to disease. For more information about potato late blight and how to control it see factsheets in English and Spanish (http://projects.cals.ncsu.edu/veggiepathology/disease_factsheets) produced by Dr. Lina Quesada-Ocampo (http://plantpath.cals.ncsu.edu/faculty/lina-m-quesada-ocampo) at Department of Plant Pathology (http://plantpath.cals.ncsu.edu/). Control recommendations are also available in the USAblight website (http://www.usablight.org/), where you can also register to receive text and/or e-mail alerts when new disease outbreaks are reported.

For tomato late blight information and control recommendations, please refer to the alert released by Dr. Kelly Ivors (http://plantpath.cals.ncsu.edu/faculty/kelly-l-ivors) and the related factsheet for tomato late blight (http://www.ces.ncsu.edu/wp-content/uploads/2013/06/Tomato_late_blight_ki.pdf).

If you think you have late blight in your potatoes 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. If late blight is confirmed in your samples by an expert, please send a report at the USAblight website to alert other growers.

Control strategies are provided in the factsheets for commercial growers. Homeowners can use gardening fungicides that contain chlorothalonil as an active ingredient. Organic growers can use copper-based products to slow down disease progression.

Tomato Late Blight Alert

Late blight of tomato, caused by Phytophthora infestans, is knocking on the doors of our state border. On Thursday, June 20, 2013, the clinic received pictures from an Extension agent of what appears to be classic symptoms of late blight on potato from Watauga County, North Carolina. The clinic has yet to receive a physical sample for confirmation. Given the fact that this disease has been confirmed in Maryland, Virginia, West Virginia, Tennessee and possibly Kentucky, in addition to the recent wet and cool weather that is conducive for the pathogen’s growth and spread, we are concerned the disease will be soon arriving to North Carolina, if it’s not already here.

Without proper preventative measures, late blight can completely defoliate and destroy a crop within one to two weeks. The disease can be severe on tomatoes grown in the mountains of North Carolina, as well as in late plantings in the piedmont.

For more information about tomato late blight and how to control it see a tomato late blight factsheet produced by Dr. Kelly Ivors at the Department of Plant Pathology. Control recommendations are also available in the USAblight website, where you can also register to receive text and/or email alerts when new disease outbreaks are reported.

For potato late blight information and control recomendations please refer to the alert (http://plantpathology.ces.ncsu.edu/2013/06/pest-news-potato-late-blight-alert/) released by Dr. Lina Quesada-Ocampo and the related factsheets in English and Spanish.

Japanese Beetles Adults

We have a couple reports from around North Carolina and even reports that they are emerging in Maryland. So I guess they are trickling out, but populations seem to have gotten lower and lower in the past several years. For three years in a row we have had severe droughts during the time Japanese beetles are ovipositing. They need moist soil so their eggs do not dehydrate and so tiny young larvae can borrow into the soil. Droughts have restricted successful reproduction to only well irrigated areas. 

So keep an eye out and remember a few key things. Japanese beetle traps do not offer any protection to landscape plants, or cane berries and may actually attract more beetles on to your property so hang them in your neighbor’s yard. Likewise, treating a lawn for Japanese beetles grubs will not reduce defoliation of plants on that property since beetles fly in from great distances.  These pest are feeding aggressively in areas of ornamental plantings as well as cane berries and grapes.  Application of Bifentrhrin (Capture), Carbaryl (Sevin) or Azadirectin (Aza-Direct)  may be warranted if  you have an infestation.

Fire Ant Program

While Fire Ant's may not be a concern to many of you right now- think again, they are invading WNC and you should be prepared to control them on your farm.  Many vegetable and fruit growers move materials around that these pest can find ways of moving from your farm to that of another or from elsewhere to your farm.  Consider attending this program on July 17th to learn more about this pest.  Fire Ant Program

Cucurbit Downy Mildew Found in NC

Downy Mildew Found in NC Cucurbit Crops

Hello Vegetable Grower
This post comes from our new Vegetable Disease Plant Pathologist at NC State University; Lina MarĂ­a Quesada:  
.................................................
Hello all,

I hope you are having a good day. I am the new vegetable pathologist at NCSU and I am writing to let you know that cucurbit downy mildew was found in Wayne county, NC, yesterday. Cucurbit downy mildew can be a devastating disease and I am hoping this information will help you assist cucurbit growers this growing season.
See the pest news with further information here:
http://plantpathology.ces.ncsu.edu/2013/06/pest-news-5313/
See current cucurbit downy mildew reports here (you can sing up to receive alerts):

See a fact sheet in English and Spanish about cucurbit downy mildew with control recommendations here (if you have any problems downloading, I can email the pdf files to you):
http://projects.cals.ncsu.edu/veggiepathology/disease_factsheets
We recently developed a plant pathology extension portal were we are centralizing plant disease information. Myself and other extension specialists in the department of plant pathology will be using that portal to post pest alerts: http://plantpathology.ces.ncsu.edu/
You can sign up to receive news feed from the plant pathology portal into your county local portal if you want to receive these pest alerts, either the person that handles your county portal or extension IT here on campus should be able to provide guidance on how to do this. You can also follow me on Twitter (https://twitter.com/QuesadaLabNCSU) and/or Facebook

If you have any problems accessing this information, or have any questions please send me an email.
Thanks for your help and have a good rest of the day!
