RAINS SOG a peanut field in Seminole County, Ga. With warm, wet weather the norm so far this year, peanut diseases will be significant. Growers are encouraged to invest in needed fungicide programs.
Alabama and Georgia peanut fields have been a bit swampy this summer.
Hard downpours and prolonged soggy times have created perfect disease patterns in peanuts and has hindered much-needed fungicide applications. It’s been a tricky year so far.
“Growers need to know that leaf spot, white mold, Rhizoctonia limb rot and even Cylindrocladium black rot are likely to be problematic this year,” said Bob Kemerait, plant pathologist with the University of Georgia Cooperative Extension. “Diseases will be of significant concern this season, and growers are encouraged to invest in the fungicide program their crop needs for optimal yields.”
Peanut farmers need to consider fungicides with both systemic and curative activity this year for leaf spot control. “With the weather this summer, there is a good chance that some leaf spot is already present in a field before a fungicide program can be established,” he said.
The best leaf spot programs, he said, include Headline or Provost. Fontelis works well on leaf spot, too. And for increased leaf spot control, growers now can mix Abound at 18.5 fl oz/acre with Alto at metconazole, 5.5 fl oz/acre.
“All of our soilborne programs are effective for use in our peanut fields. However Abound gets special attention for Rhizoctonia limb rot, Provost for CBR, and Artisan, Convoy and Fontelis for white mold,” he said. “Tebuconazole is a great value for the price. However it is not the best soilborne fungicide our growers can choose.”
