Here are some pointers:
- The new polymer coated seed treatments are not red. The color “red” is not magic. The response to green colored seed has me thinking about Dr. Seuss when I get some questions. “I am afraid to pour green seed from the bag; I am afraid to put green seed in the hopper; I am afraid to plant green seed in the field; I am afraid I do not like them Sam-I-Am”. For generations, “red” has been the color of peanut seed treatments. “Green” is going to be a huge innovation for out peanut seed industry and our growers.
- Growers who do not have a problem with nematodes, or who have a problem with nematodes and plant a root-knot nematode resistant peanut variety, and who have good quality seed likely do not need any additional fungicide or nematicide in the furrow.
- Peanut growers with a root-knot nematode issue are encouraged to plant a root-knot nematode resistant variety or use a nematicide (Telone II fumigation, AgLogic 15G, or Velum) to fight the nematodes. We continue to assess the Vydate CLV (34 fl oz/A in-furrow at plant for nematode control) which is labeled as well.
- Use of Velum not only helps against nematodes, but also helps against Aspergillus crown rot and early season leaf spot. Velum alone does not fight thrips; something must be mixed with it. Because of cost, I would not use Velum unless I have a nematode problem. Velum is the “Cracker Jack” extra seedling disease and leaf spot control is the “prize” at the bottom of the box. You don’t buy Cracker Jack for the prize, though you are glad it is there.
- Use of AgLogic, Velum, or perhaps Vydate is an essential tool for protecting a peanut crop against roo-knot nematode. Because the lesion nematode affects the pegs, protecting against lesion nematode, like further protection against root-knot nematode, usually involves an application of propulse (or perhaps Vydate) at pegging time.
- Growers with a problem with CBR (cylindrocladium black rot) whould consider using Proline (5.7 fl oz/A) in-furrow at planting; this could also help with early season white mold, though efficacy against early season white mold with an in-furrow application is not a sure thing.
- Use of Propulse infurrow provides fluopyram (velum) and prothioconazole (Proline).
- Both Proline and Propulse are expected to be in tight supply this year, as will be Provost Silver.
- Azoxystrobin (Abound etc) is the least expensive product to put in furrow and it does have good activity against Rhizoctonia, a seedling pathogen which can be a problem in some fields, especailly in cooler soils or where peanut follows peanut. Azoxystrobin generally goes out at a rate of 6 fl oz/A; it has less affect not against Aspergillus.
- Unfortunately for growers planting twin rows, the rate of most in-furrow products must be cut approximately in half when plance under each twin. That would be 3.5 lb/A aglofic under each twin and about 3.4 fl oz/A Velum under each twin.
