Dan Anco Clemson Comments Peanut Notes No. 263 2025

(Updated: Sept. 27, 2025, 8:54 a.m.)
In what continues to be a dynamic year, rain we had been looking for may come in a lump sum. Amounts over the next week vary from different prediction models, and a lot can change in a short amount of time. For some areas, the amount of rain may end up being just right — time will tell.


Still, for most cases, in the light of the potential amount of rain we may receive over the coming week and the number of days where we may have rainy conditions, including those days where it is misting, peanut generally fares better in the ground than it does above the ground. This is in large part due to the increased risk of mold/Seg issues if peanut is dug and exposed to increased and prolonged moisture. Windrows becoming matted and later not drying out well, or in some cases moved, can be another issue from heavy rain.


We have fields widely ranging in condition. Situations where I might consider digging before the storm would largely be limited to where Virginias are currently at over maturity with a majority of coal black pods, or where leaf spot defoliation is more than a third of the canopy. Both of those situations are currently at risk of facing higher loss that will increase with time, but even then they are not immune from risks on top of the ground. Runners tend to be more forgiving, even if their maturity now would otherwise be ready to dig.

Normally, fungicide coverage helps to provide insurance if we are not able to get back into the field following wet conditions. Based on the year we have had so far, I would reserve this for fields where the canopy (and pods) is in overall good to decent condition and those that need the extra time to finish out maturity. If a field has been under heavy drought stress and the vines are crispy or crashing, I would think more about saving the money and not spraying them, with the plan of digging them one the field is accessible again.


7-Day Quantitative Precipitation Forecast for September 25-October2, 2025. Showing rain fall amounts from 1 inches in Georgia to upwards of 5-10 inches in South and North Carolina.
