Bob Kemerait answers a few questions about PEANUT Early-Season Treatments
Question 1: “Bob, do I have to use a fungicide seed treatment on my peanut seed?”
Answer 1: “Only if you want to pick peanuts at the end of the season.”
Question 2: “Bob, which peanut fungicide seed treatment should I use?”
Answer 2: “Most peanut seed will be treated with Rancona this year because it was more effective in 2020 against pathogens such as Aspergillus flavus and Aspergillus niger than was Dynasty PD. If, for some reason, your seed is treated with Dynasty PD in 2021, this does not mean you will have a stand problem, it is still a good treatment, but there will be higher risk to stand issues.”
Question 3: “Bob, does every peanut farmer in Georgia need to use an in-furrow fungicide to compliment the fungicide seed treatment?”
Answer 3: “Great question, and the answer is “NO”. Many growers, especially those with high-quality seed, good rotation, careful planting dates and conditions, do NOT need an in-furrow fungicide. In-furrow fungicides provide additional stand insurance, that may or may not be needed. Growers MOST likely to consider use of an in-furrow fungicide product at planting are those who have questions on quality of their seed, 2) are planting saved seed (but not always), 3) growers planting into cool and wet or hot and dry soils, 4) growers who are planting in a field where getting a good stand has been a historical problem, and 5) growers who will just sleep better at night knowing they put one out.
Question 4: “Bob, what about putting Azoxystrobin out in-furrow?”
Answer 4: “Azoxystrobin is inexpensive and effective against some important fungal pathogens, especially Rhizoctonia. It is less effective against Aspergillus crown rot. As an inexpensive “good but not great” fungicide, I like it. But, it may not be needed and it does have limitations.”
Question 5, “Bob, in addition to azoxystrobin, what else is there and when would we use them in-furrow?”
Answer 5: “Glad you asked, see below.”
Peanut nematodes (single row, in-furrow only) Velum 6.5-6.9 fl oz/A (Remember “VELUM” is NOT “VELUM TOTAL” and does not include a thrips material. To control thrips would require coupling Velum with Thimet or imidicloprid, etc. Also provides additional control of Aspergillus crown rot and some early-season control of leaf spot.
Peanut nematodes (single row, in-furrow only): AgLogic, 7 lb/A also controls thrips
Peanut nematodes (single row, in-furrow only) Propulse 13.6 fl oz/A + Velum 1.5 fl oz/A. Note, this option also covers Aspergillus crown rot, CBR, early season leaf spot and some suppression of early -season white mold. MUST ADD something for thrips control CBR and other diseases but not nematodes (single row, in-furrow only) Proline, 5.7 fl oz/A OR Propulse 13.6 fl oz/A. Propulse is also good on Aspergillus crown rot.
Note: If you are using Velum or Propulse, there is no need to also include Azoxystrobin, unless there is some reason to be concerned about Rhizoctonia seedling blight. FOR TWIN ROW Peanuts: All above rates are cut in half for EACH twin row. Yes, if effects efficacy, but that is the way it is.
