Dan Anco Clemson Peanut Notes No. 33 2021

— Written By
Corn planting has been rolling and little by little, the thought of planting peanuts is crossing minds. We have had some warm days, though we also have a few nights dipping into the 30s. The season is still in its infancy, with better planting conditions ahead, including all of May. Rain this coming weekend should help add back moisture to soils, many dryland acres can use the rain.
As a quick reminder, planting early increases thrips and tomato spotted wilt virus risk. If planting in April with imidacloprid in-furrow, or making a blend of Velum with imidacloprid (recreating a tank mix of Velum Total since Velum alone does not have thrips insecticide), keep an eye for thrips injury come emergence time and be prepared to apply acephate over the top (near 21 DAP). Many good choices are available for thrips in-furrow, and while not putting an insecticide out is still a choice, excluding an insecticide at-planting is not the choice I would recommend for protecting seedling health and pod yield.
Some questions have been asked of newer high oleic runners, like how Georgia 16HO compares with TUFRunner 297 and FloRun 331. All three have shown great yields and economic value in our tests. 331 tends to grade a few points lower than the other two, though its yields have made up for this. 331 is probably the tallest canopy out of the 3, though all 3 close the rows well. 331 is the smallest of the three as far as seed size, being approximately 675/lb compared to 625/lb for 16HO (a tiny bit bigger than 06G) and 600/lb for 297. This makes the order of dryland drought tolerance roughly 331>16HO>297. For disease, a rough ordering for virus resistance is 297>16HO>331, though 331 is noticeably better than TUFRunner 511 shows. 331 has a little leaf spot resistance, and 297 has a little white mold resistance. All three seems to still be in the 145 to 150 day maturity range, but a warmer year can move this a little quicker.
