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 →

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 →

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 →

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 →

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 →

This year’s peanut yields in Georgia was among the state’s highest, but University of Georgia peanut agronomist Scott Monfort fears that next year’s crop will be vulnerable to increased disease pressure.
Monfort, a guest speaker at Thursday’s (Jan. 21) Georgia Peanut Farm Show at the UGA Tifton Campus Conference Center in Tifton, Georgia, said Georgia farmers averaged 4,470 pounds per acre this year, the state’s second highest total over the past several years. However, because commodity prices remain low, he fears farmers are hesitant to grow cotton and corn crops at the acreage they’ve grown in the past. Continue reading →
