Dr. Mark Abney, research and Extension peanut entomologist at the University of Georgia Tifton Campus gave an entomology update at the UGA Southeast Research and Education Center. At this location, Dr. Abney said they have a research trial looking at different materials for managing thrips. Thrips are an early season seedling pest, but they remain a concern throughout the growing season. They cause damage to the plant by feeding on it and by spreading Tomato Spotted Wilt Virus. The research he is conducting in Midville will allow him to make recommendations to growers for how to best manage thrips on their farm.

For the 2018 crop year, thrip pressure has varied across the state. Some areas have seen very little pressure, while others have had moderate to heavy pressure, as well as higher levels of TSWV. Overall, Dr. Abney thinks virus levels are lower than they were in 2017; however, it is still there and needs to be managed.

Another major insect affecting peanuts that Dr. Abney studies is the burrow bug. The burrow bug is a stink bug that lives in the ground. It feeds on the developing peanut pod inside the shell and causes grade loss for farmers when they sell their peanuts at a buying point. This grade loss equates to financial loss for the farmer. The insect is difficult to manage; however, Dr. Abney has a few ways to monitor and control them. He is working to understand the biology of the insect better, as well as looking at potential products to use to control it. Currently, there is only one insecticide available to control the burrower bug and it is slated for cancellation by the Environmental Protection Agency, so research is being done to find another alternative product. Another soil insect pest Dr. Abney studies is the southern corn root worm. It’s not a big problem for most growers in Georgia; however, it’s an insect that likes wet weather, so during raining growing seasons, it can be seen. It is also managed with the same product used on burrower bugs, so an alternative management product is needed for it as well.

Dr. Abney said insect management is really important for peanut growers even though it’s not typically something they think about when managing their production practices. He and his colleagues continue to work to find more tools for Georgia peanut farmers’ tool belts so they can better manage insect pressure on their farms and continue to grow quality Georgia peanuts.

While at the University of Georgia’s Southeast Georgia Research & Education Center, tour attendees were given a disease update from Dr. Bob Kemerait, Extension plant pathologist at the University of Georgia Tifton Campus. Kemerait said diseases are one of the biggest problems for peanut production in Georgia and many are caused by viruses, fungi and nematodes. At the research and education center in Midville, Dr. Kemerait and others are working to learn more about managing diseases in peanuts and giving that information to the farmer to help him grow a better crop. He said the research he is doing is two-fold; one to find an integrated management system for how to manage a virus and two, to do trials and experiments to evaluate what is available in terms of varieties and fungicides that can help growers better manage diseases.

One disease Dr. Kemerait and his colleagues focus on frequently is Tomato Spotted Wilt Virus (TSWV). According to Kemerait, TSWV is one of the most devasting diseases affecting peanuts. With his research, he is working to understand the relationship between the disease and the vector that spreads the disease, which is a small pest called a thrip. By understanding the relationship, he can create models to predict how many thrips would be in the field and how to best manage the spread of the disease. Dr. Kemerait also studies how other factors affect TSWV such as variety, use of in-furrow insecticide and planting date.

Another aspect of his research is the use of fungicides for disease control. Diseases such as leaf spot and white mold can take millions of dollars to control; however, Kemerait says if they are not managed properly, they could cost tens of millions of dollars in yield reduction from the peanut crop. Kemerait says if growers want to remain profitable, they know they have to fight diseases by taking the research produced at the University of Georgia and integrating it into their production practice, as well as being “upfront” about prevention.

The final day of the Georgia Peanut Tour began at one of Bulloch County’s largest farming operations, the farm of Charley and Lee Cromley. The Cromley brothers are fifth generation farmers who grow approximately 2,600 acres of row crops. This year, 1,800 acres were planted in cotton and 800 acres were planted in peanuts. When discussing the current crop, Lee said their biggest challenges this year have been weed and disease control. The large amount of rainfall during the growing season has made it difficult to get tractors in the field to manage these two pests.

The Cromley brothers’ production practices include a good rotation of cotton and peanuts, application of Elatus for leaf spot control, Valor and Cadre for weed control, and practicing strip tillage. Strip tillage allows them to turn the dirt less, which keeps necessary nutrients and moisture in the soil for the crop. They also plant a cover crop and leave the previous year’s cotton stubble in the ground prior to planting peanuts each year.

Harvest season has commenced, so while at their farm, tour attendees got to see peanuts being dug. Here, the tractor pulls an implement called a peanut digger. This machine digs the peanuts, shakes the dirt off and inverts them upside down so the peanuts are exposed to the sun and the vines are on the ground. Lee said they can dig approximately 60 acres per day with two machines going. After they are dug, the peanuts are left on the ground to dry for approximately three days and then later harvested with a combine, which is a machine that “picks” the peanuts off the vine. Last year, the Cromley brothers harvested approximately 5,000 lbs/acre on their peanut crop. This year, they are expecting to harvest around 4,000 lbs/acre.

During the visit, Lee also pointed all the importance of peanuts to the economy; especially rural South Georgia. Agriculture makes up 10 percent of Bulloch County’s budget according to Bill Tyson, Bulloch County Extension agent. Peanuts are Georgia’s official state crop and generate approximately $2.2 billion annually to the state’s economy. They are grown in nearly half of Georgia’s counties where they account for nearly 50 percent of the peanuts grown in the United States.

According to Tyson, the 2018 peanut crop is looking good in his area of the state. The Bulloch County area started off the season wet, with a slow start, followed by cooler temperatures in May. Due to the changes in the weather pattern, much of the crop is spread out in regard to planting dates. Like many other areas, the abundant rainfall has created more disease issues than normal, as well. The farmers in the county grow approximately 75,000 acres of peanuts and cotton; however, they also grow corn, soybeans and small grain. Most of the land in Bulloch County is dryland with approximately 25 percent irrigated.

After seeing peanuts harvested on the farm, tour attendees traveled to Savannah to tour the Georgia Ports Authority’s Garden City Terminal. The Garden City Terminal is the largest single-terminal in North America and serves 20 percent of the United States population and industry. The facility is 1,200 acres and offers nine container berths comprised of nearly 10,000 ft of contiguous space. The terminal is also home to 30 container cranes; the largest on the East Coast.

According to the American Peanut Council (APC), the U.S. is the third largest peanut producer after China and India, and is the leading peanut exporter with an average annual export of 200,000 to 250,000 metric tons. Canada, Mexico, Europe and Japan account for more than 80 percent of U.S. exports. The largest export markets within Europe are the Netherlands, the United Kingdom, Germany and Spain.

Lee Beckmann, manager for government affairs for GPA, visited with the tour attendees during Hot Topics on Tuesday and gave an overview of current port projects. One key project is the Savannah Harbor Expansion Project. Here, the harbor is being dredged to 47 feet to better accommodate vessels. The vessels being used now are 14,000 TEUs – the largest on the East Coast. Currently the channel depth is 42 ft and the project is 50 percent complete. Another major project in the works is the Mason Mega Rail Project. This will end up being the largest intermodal yard for a terminal in the U.S. Currently, phase one is expected to be completed by September 2019 with the first bundle of tracks operational. Phase two is expected to be completed by September 2020.

The Garden City Terminal sees an average of 10,000 truck transactions per day. For single moves, trucks average 33 minutes and for doubles they average 53 minutes. When it comes to the containers they are transporting, the terminal houses 25,000 loaded containers and 35,000 empty containers. Nearly 55 percent of the containers are for imports and 45 percent of exports.

According to GPA, it received its second busiest month on record for containerized trade in July 2018. This was a 12.7 percent increase compared to July 2017. GPA also said rail cargo at the Garden City Terminal increased by 16 percent (60,000 containers) for a total of 435,000 rail lifts between July 2017 and June 2018. This increase in capacity is a driving force behind making Savannah an even more competitive port option on the East Coast.

When looking at Georgia’s economy, GPA says the logistics industry, including the port, provide a boost to Georgia’s economy. For GPA alone, the following statistics relate to the state of Georgia:

• 440,000 full and part time jobs
• $106 billion in sales (11 percent of total sales)
• $44 billion in state GDP (8 percent of total GDP)
• $25 billion in income (6 percent of total personal income)
• $5.9 billion in federal taxes
• $1.4 billion in state taxes
• $1.5 billion in local taxes
