Georgia scientists help map the genetic code of peanuts

Posted on January 5, 2018 by rhallberg

by J. Faith Peppers, University of Georgia

An international group of agricultural scientists, including University of Georgia and USDA scientists based in Georgia, have mapped the genetic code of the peanut. Results of the five-year research project give scientists around the world a map with which to unlock some of the genetic potential of the peanut plant.

“Mapping the genetic code of the peanut proved to be an especially difficult task, but the final product is one of the best ever generated,” said Steve Brown, executive director of The Peanut Foundation (IPF). “We now have a map that will help breeders incorporate desirable traits that benefit growers, processors, and most importantly, the consumers that enjoy delicious and nutritious peanut products all over the world.” Continue reading →

Southern SARE research shows cover crops reduce pest populations

Posted on February 22, 2017 by rhallberg

Preliminary research from University of Florida has found that incorporating root-knot nematode-resistant cover crops in a perennial peanut rotation reduces pest numbers in the cash crop and improves yields.

The results may be helpful for producers who choose top-yielding, yet susceptible, peanut cultivars, as well as resistant cultivars that historically carry a lower yield. Root-knot nematodes, soil parasites predominant in areas with hot climates and short winters, can reduce perennial peanut yields and affect plant health by feeding on plant roots. Continue reading →

Leaf spot disease a major problem for Georgia peanut growers

Posted on December 1, 2016 by rhallberg

by Kyle Dawson, University of Georgia

Georgia peanut growers are experiencing problematic leaf spot diseases this year due to susceptible varieties and weakening fungicide treatments, according to Albert Culbreath and Tim Brenneman, plant pathologists at the University of Georgia Tifton Campus.

Brenneman said this year’s dry conditions should have set up an environment that’s less favorable for leaf spot. Continue reading →

Disease control is essential for high peanut yields

Posted on April 12, 2016 by rhallberg

In Southwest Farm Press

by Ron Smith

Variety selection, rotation, field history, and fungicide applications play important roles in controlling foliar and soilborne diseases in Oklahoma peanuts, and with depressed commodity markets, the challenge is choosing the right variety, maintaining a proper rotation, and developing an efficient, economical, and effective fungicide program.

“Variety selection is the first decision,” says Oklahoma State University Extension Plant Pathologist John Damicone, who spoke at the recent Oklahoma Peanut Expo at Altus. “But, it has become a lot harder for growers to get the seed they want; they’ve had to plant a lot of varieties from the Southeast lately.” Continue reading →

Peanut-cotton rotations help prevent nematodes, weeds

Posted on February 4, 2016 by rhallberg

In Southwest Farm Press

Peanuts are a good complement to cotton, especially in fields infested with cotton root knot nematodes, says Jason Woodward, Texas A&M AgriLife Extension plant pathologist at Lubbock. The microscopic pest won’t affect peanuts and the peanut root knot nematode won’t injure cotton.

He discussed the nematode factor and peanut best management practices by Skype hookup during the recent Red River Crops Conference at Altus, Okla., as well as disease issues, varieties, and market types. Continue reading →

Root knot nematode is a real problem for peanuts

Posted on January 29, 2016 by rhallberg

In Southeast Farm Press

Rome Ethredge, Contributing writer

I remember one year a grower was going to plant peanuts in a small field that had been in pasture for over 15 years. He said the last time he had peanuts there he had noticed some nematode damage at harvest time. We thought that with the good rotation, he shouldn’t have a problem. We were wrong.

The peanut root-knot nematode (Meloidogyne arenaria) is a force to be reckoned with and caused yield limiting damage again after all those years since we used no nematicide or resistant variety. Continue reading →
