Drought and Harvest Question Greene County Peanut Notes No. 258 2025

Question:

I looked at three fields this morning, all on sandy land and planted around May 8th. This area has been dry. The grower noticed this issue starting to occur about 2-3 weeks ago but now the plants are very wilted and brown. The field is patchy but large areas of the field are starting to look like this. There are still some areas of the field that still look healthy. The affected plants have less pods than the healthy plants. I will attach a few photos of this to this email. Inside some of the pods the peanuts look to be molding.

They do want to wait longer in the other fields for the peanuts to mature more. They asked if they should dig the affected areas and leave everything else. Do you have an opinion on doing that? I figured it would be best to just wait and dig at one time.

Jordan:

It depends on what percent of the field is in that shape. If the healthy plants are not mature and need more time and are the primary type of plant, the grower should wait. While not ideal, the stressed plants won’t completely shed if they stay out longer. What percent is not wilting?

Follow Up:

I am not the best at guessing percentage so I took drone photos. The last 2 photos are the same field. I would say the first 2 fields are maybe 40%-50% not wilted but the last field has a lot of wilting.

Jordan:

Great images! The last one could be dug at any time. I don’t think it will get any better. First could wait. Not sure how far they are from being mature.

Jordan:

I might not have answered your question at the end. I just looked back and saw the mold statement. If they can dig bad areas and good areas separately that might help keep a load from going seg 2 that had good peanuts. Actually, they can dig at the same time but harvest separately. Your drone images might help them a lot in this case.

*Seg 3 is a potential issue for the drought stressed peanuts because of A. flavus and production of aflatoxin. Growers in the southeastern US with center pivot irrigation often harvest the corners of fields that are outside the circle separately from the irrigated peanuts to avoid Seg 3 status for the good peanuts. Same logic might hold for the situation we find ourselves in here.
