Leaf spot disease a major problem for Georgia peanut growers

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

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

UGA peanut agronomist fears Georgia’s peanut crop could be vulnerable to increased disease pressure next year

In Georgia FACES

By Clint Thompson, University of Georgia

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

Disease management is a lot like the battle of Gettysburg

In Southeast Farm Press

by Bob Kemerait, University of Georgia

As my family and I drove on a mid-July morning, passing field after field of peanuts, I said this time of the season reminded me of the Battle of Gettysburg. One child slumped in his chair and became more intent on his computer game. The other exclaimed softly, “Oh-my-gosh…..” and steeled herself for the analogy to follow.

The Battle of Gettysburg was fought between July 1 and 3 in 1863.  Though the Civil War raged for almost another two years, the die was cast for the Confederacy at Gettysburg.  On April 9, 1865, General Lee surrendered the Army of Northern Virginia at Appomattox Courthouse and the war was mercifully over.  At this point I heard a prolonged sigh and an exasperated question from the back of the truck, “What has THAT got to do with peanuts??”

Planting date impacts peanut disease pressure

In Southeast Farm Press

A cooler, rain-soaked spring in parts of the Southeast pushed peanut planting dates later than usual, a factor that can impact the type and incidence of disease growers experience throughout the remainder of the season.

“Planting dates definitely make a difference in peanut diseases, both in the type of disease you have and the pressure,” says Austin Hagan, Auburn University Extension plant pathologist.

White mold still major disease for peanuts

From Southeast Farm Press

White mold continues to be the top disease problem for Southeastern peanuts,  and that’s not likely going to change anytime soon. But new options for controlling it continue to become available.
