Checking Peanut Maturity

The following update was prepared by Clemson peanut specialist Dan Anco.

Just a quick note to stay on top of checking peanut fields for maturity. Several fields from Barnwell, Dorchester, and Calhoun County are showing fields ready to dig. In some cases (not all), Bailey at 123 days after planting are showing 80% of blasted pods with orange-brown-black color. Another field with Georgia 06G at 121 DAP is registering 73% color with 45% brown. Many areas of the state have had fairly frequent rains and favorable temperatures, and as such some places are seeing some maturities a little on the early side. This is not the case for all parts of the state or every field in each part of the state.

No two fields/crops are the same, and the best decision for our field may not be the same as for our neighbor’s. Nevertheless, scouting our fields and getting an idea where each one sits maturity-wise helps keep us informed and can prevent untimely surprises. Checking maturity is also beneficial when determining if we need one last fungicide spray. From past years we know the weather can surprise us sometimes and delay harvest, but if evidence shows particular fields are ready to dig within the next week, according to the label most fungicides require a preharvest interval of 14 days.

As a guide, for Virginia type varieties we target harvest around 70% of blasted pods with color (orange, brown or black), with 30% of pods in the brown + black category.

For runners, we generally target 75 to 80% pod color, with 40% in the brown + black category.

Friday, September 1 there will be a blasting clinic at Pee Dee Peanut in Mullins starting at 10 am (Pee Dee Peanut: 843-464-2300).
