Weather across most of Georgia, hot with better-than-even chance of rain, remains perfect for development and spread of fungal diseases in our row crops.<\/span><\/p>\n

Southern corn rust arrived very late, but is spread across the Coastal Plain of the state.\u00a0 Southern corn leaf blight and northern corn leaf have been much more problematic this year.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

CORN ISSUE OF MOST CONCERN NOW:\u00a0 Ear rots and mycotoxins (aflatoxin and fumonosins)\u00a0 Please refer back to e-mail from Dr. Noland about harvest and management of mycotoxins.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

\u00a0<\/span><\/p>\n

SOYBEAN RUST still only found in kudzu in Appling, Decatur and Grady Counties, though it has likely spread.\u00a0 Remember that critical times to protect the soybean crop are between first bloom (R1) and full-seed (R6) growth stages.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

COTTON:\u00a0 Target Spot is here and across the Coastal Plain.\u00a0 Not every grower will benefit from protecting the crop with a fungicide; however every grower SHOULD be aware of the potential for loss and the opportunity to protect the crop.\u00a0 Considerations for protecting the crop should be made from the first week of bloom through the sixth week of bloom.\u00a0 Growers are encouraged to scout their fields for early detection of the disease; conditions are perfect now.\u00a0 When defoliation of the crop is greater than 25% or so, it is not clear a fungicide will help any more.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

AREAOLATE MILDEW of cotton (looks a lot like a powdery mildew) is reportedly back in some cotton as far west as Colquitt County.\u00a0 Normally areolate mildew comes in late and does not cause a problem as far as yield goes; however if the diseases develops early, premature defoliation could be a problem.\u00a0 If areolate mildew develops well before intended defoliation timings, fungicides (same as used for target spot) could be helpful, though WE HAVE VERY LITTLE DATA TO SUPPORT that recommendation.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

PEANUT:\u00a0\u00a0<\/span>\u00a0 Conditions are PERFECT for white mold and leaf spot now in the peanut crop.\u00a0 Growers are strongly encouraged to stay on a timely fungicide program.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

NO PROGRAM WILL KEEP ALL WHITE MOLD OUT OF A FIELD.\u00a0 Individual affected plants are going to happen.\u00a0 A good program keeps individual hits of white mold from turning into 10-foot runs of wilted plants.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
