Southern rust of corn confirmed in Calhoun Co., FL today. Detected by consultant Caleb Traugh & confirmed microscopically by Ethan Carter @UFIFASPeanut. Special thanks to @bobkemerait for his help and teamwork! @CropNetwork https://t.co/6JgFmWzh85
“Late” leaf spot detected on peanuts at 62 days after planting in Williston, FL. Excellent photo and scouting by 6Gen Ag Services. This field had already received three fungicide sprays starting at 28 DAP. Info & photo courtesy De Broughton - 6genagservices.cca on Instagram.
Likely symptoms of Watermelon mosaic virus. Causes patterns of dark & light green to yellow patches on leaf. Leaf distortion is common. Symptom vary by virus concentration, timing of infection, single/mixed infections or temperature. WMV is spread by aphids #Plantdisease#Virus

Pnut digging and stem rot rating in Marianna, FL research plots. Plenty of late leaf spot too. Thanks for all the help! @ UF IFAS North Florida Research and Education Center (NFREC) Marianna https://t.co/oYI8Flwu0S
Took soil samples for nematodes in peanut trial @nfrec_sv. Leafspot trial (collaboration with @IanMSmall1) with root-knot nematode there. Fungicide regimes, cultivars, and winter cover crops.
Chlorosis mostly leafspot. Variable canopy closure among cultivars partly nematodes.
