Black Walnut Harvest

The field crew started harvesting black walnuts for a research trial being conducted in cooperation with Hammons Black Walnut company in Stockton, Missouri. The nuts for each grafted variety are collected, hulled, bagged and labeled. Hammons will generate data for the improved varieties including total lbs., % moisture, shell weight, nut meat % and grade them. The guys were kind enough to stop working and pose for a photo.

Brown Marmorated Stink Bug Found In High Tunnel

Brown Marmorated Stink Bug (BMSB) was collected in the High Tunnel on the raspberry plants and identified by our Entomologist Dr. Maciej Pszczolkowski.  The BMSB is native to East Asian and was introduced to the US in 1996. It has since been identified as a potential risk to agriculture and a nuisance to homeowners. BMSB feeds on a wide range of fruits, vegetables and other plants. The feeding usually begins in May-June and causes distortions of the fruit.  Offspring produced during the summer survive by overwintering as adults in structures.  As raspberry harvest is still going strong, we will continue to monitor and collect BMSB.

Ningxia University Students Tour the Fruit Station

Representatives from MSU International Leadership and Training Center and approximately 50 students from the Ningxia University in China visited the Fruit Station to learn about the research we are conducting and the facilities and resources we have to offer.  The students are currently attending Missouri State University in Springfield, Missouri.  Students were introduced to the Mountain Grove campus faculty, participated in presentations about the Fruit Station and current research projects.  Then students then had the opportunity to tour the laboratory, the distillery/winery, visit our sales floor and the weather cooperated and we were able to take a wagon ride through the research fields.

USA tour of Mountain Grove Campus

The USA staff Ambassadors visited the Mountain Grove Campus on Friday, October 7 in the afternoon. We started out with a meet and greet with Dr. Hwang and all available faculty and staff followed by a tasting of MSU wines and spirits with C. J. Odneal, Shelia Long and Jeremy Emery. Martin Kaps, Susanne Howard, Randy Stout and Jeremy Emery then took the group on a hay ride through the field plantings followed by a winery and distillery tour. At the end of the tour, staff picked up any wine or honey that they ordered from Leslie Akers and Pam Turner. Lovely weather and a fun event for all of us.

Sweet potato fasciation

John Rumfelt brought his weird looking Beauregard sweet potato vine in to the station wondering why it looked so strange. It is fasciated – flattened and ribbed – due to hormonal imbalance from a mutation or other factors. Fasciation is not contagious and John told Leslie Akers that the vines had a good amount of sweet potatoes. I have seen this symptom on highbush blueberry and apple branches, but this is the first time I saw a fasciated sweet potato! To read more about fasciation, see Fascinating Fasciation at https://hort.purdue.edu/ext/fascinatingfasciation.html

This sweet potato vine is fasciated showing a flattened, ribbed stem.
