Some areas of Alabama received more than adequate rainfall this summer, but the extremely high temperatures still took a tool on cotton, peanut and soybean crops.
White mold development
White mold development also drops off considerably as peanuts enter the month of September, he adds. Later planted peanuts have a lower risk of the disease, he says.
Peanut producers in Alabama haven’t seen much tomato spotted wilt virus this year, says Hagan. “This is a good thing, but it doesn’t mean the virus is gone. All we have to do is have a mild winter or two, have good survival with the thrips that vector the virus, and it’ll be back next year. But at least we got a rest from it this year,” he says.
Even in areas of Alabama that have received timely rainfall, the extreme temperatures of this summer are taking a toll on the state’s cotton crop, says Dale Monks, Auburn University Extension cotton agronomist.
“Even in our irrigated cotton, you can look at the tops of the plant and see the damage being done by high temperatures. Look in the middle of the plant, and you’ll find a lot of little squares and bloom tags that never made it to being a boll, and that’s what the heat has done. You can replace rain some with irrigation, but when temperatures reach 95 to 100 degrees, you’ll start shedding fast,” says Monks.
At this time of year, rainfall may help to fill out the bolls, but it also may be a hindrance as defoliation begins, he says.
Potash deficiencies are showing up in some of the state’s cotton crop, says Monks. “The early season cotton shows it first because it’s drawing more out of the soil. If there’s a deficiency, it shows up on early varieties first and then follows into the full-season varieties,” he says.
