Thrips & TSWV Management: This is Your One Chance, Don’t Mess Up.

I will make this post as straight forward as I can.

  1. UGA research shows that for every 1% Tomato spotted wilt Virus (TSWV) incidence in GA-06G at the end of the season, peanuts lose 20 pounds of yield per acre.
  2. Most thrips management options and all TSWV management options end when the seed furrow closes.
  3. Early planted peanuts (prior to 10 May) are at increased risk to thrips injury and TSWV.
  4. Phorate (Thimet) is the only insecticide that reduces the risk of TSWV in peanut. It doesn’t matter how much we wish there was something else, there is not.
  5. Everything costs more in 2022, and most people are looking for ways to save money. Consider this: every peanut field in Georgia in 2022 will be infested with thrips, and some of those thrips will be infected with TSWV...100% chance. Thrips and TSWV management may not be the place to cut costs.
  6. Using Peanut Rx will help growers assess TSWV risk and identify practices that can reduce risk.
  7. We can do everything right and still have TSWV, but if we plant in high risk situations, there should be no surprise when virus symptoms start to show up in June and July.
  8. Our one chance to get thrips and TSWV management right, is now. Let’s not mess it up.
