University of Georgia plant pathologist Tim Brenneman studies peanut diseases and a range of pests that attack peanuts. During the 2023 Georgia Peanut Tour visit to the University of Georgia Attapulgus Research and Education Center, Brenneman discussed nematodes and the impact this pest has on peanuts.
“Nematodes are a very serious problem with peanuts,” Brenneman says. “They are round worms that live in the soil and feed on the roots and the pods of peanuts.”
Today, researchers are phenotyping new varieties that have a great level of resistance to nematodes. According to Brenneman, that’s a huge advancement because some of the most expensive chemicals put on peanuts are geared to manage nematodes.
“Management of nematodes is a huge cost of production, so these new varieties with extremely high levels of resistance are beneficial to farmers since they require no chemical inputs,” Brenneman says.
Brenneman is working with the peanut breeders to phenotype. Through phenotyping, Brenneman and the breeders work to characterize the new lines and show how resistant they really are in the field as well as making sure they have the high yield potential that growers need for new commercial peanut varieties.
“It’s very exciting to see the big differences out here in the field among current peanut varieties and some of the new nematode resistant varieties. Some of the new varieties will be available within the next couple of years that should help our industry and growers produce high yields at a lower cost,” Brenneman says. “That’s what we need to stay competitive in the world peanut market.”
During the 2023 Georgia Peanut Tour, Scott Monfort, University of Georgia Extension peanut agronomist, provided an update on the peanut crop and some of the some of the issues growers have dealt with throughout the season.
Jake Fountain, mycotoxin and post-harvest pathogen specialist at the University of Georgia, provided an update on his research program during the 2023 Georgia Peanut Tour. Fountain’s research program primarily focuses on aflatoxin issues in peanuts and also other crops overall.
Nino Brown, University of Georgia peanut breeder provided an update to 2023 Georgia Peanut Tour attendees on the peanut breeding program at the university. Brown works closely with Bill Branch, peanut breeder at the University of Georgia, as they work to develop new cultivars or varieties of peanuts for growers in Georgia and beyond.
The 35th annual Georgia Peanut Tour kicked off with a Hot Topics seminar on Tuesday, Sept. 12 at the Cloud Livestock Pavilion in Bainbridge, Georgia. The seminar provided an update on the 2023 peanut crop as well as an update on the farm bill and other legislative activities that can have an impact on the peanut industry. Each year the seminar also highlights some of the latest hot topics happening in the industry and this year’s special focus included advancements in integrative precision agriculture for enhanced peanut production and processing. The speakers provided an overview of the University of Georgia FoodPIC Center and the USDA Peanut Germplasm Collection as well as information on irrigation technologies and precision agriculture in peanut production.
