If you want to do all you can do to minimize spotted wilt: Following strip tillage (5), AP-3 peanuts (10) are planted in twin rows (5) on May 18 (5) using Thimet in the furrow (5) with a final stand of 4.5 plants per foot of row (5). No Classic herbicide is applied (0). Risk Index = 35 You can try a “High-Point” variety and still avoid high risk: Following strip tillage (5), Flavorunner 458 peanuts (50) are planted in twin rows (5) on May 22 (5) using Thimet in the furrow (5) with a final stand of 4.5 plants per foot of row (5). No Classic herbicide is applied (0). Risk Index = 75 A "Low-Point" variety alone may not be enough: Following conventional tillage (15), Florida-07 peanuts (10) are planted in single rows (15) on April 15 (30) using Temik in the furrow (15) with a final stand of 1.5 plants per foot of row (25). Classic herbicide is applied (5). Risk Index = 115 Thimet or Phorate alone is not enough: Following conventional tillage (15), SunOleic 97R peanuts (50) are planted in single rows (15) on April 10 (30) using Thimet in the furrow (5) with a final stand of 1.5 plants per foot of row (25). Classic herbicide is applied (5). Risk index = 145 If you prefer not to use Thimet or Phorate, you can still have low risk: Following strip tillage (5), Carver peanuts (20) are planted in twin rows (5) on May 23 (5) using Temik in the furrow (15) with a final stand of 4.5 plants per foot of row (5). No Classic herbicide is applied (0). Risk Index = 55 If you must plant early, you can still have low risk: Following strip tillage (5), Tifrunner peanuts (10) are planted in twin rows (5) on April 20 (30) using phorate in the furrow (5) with a final stand of 4.2 plants per foot of row (5). No Classic herbicide is applied (0).Risk Index = 60 If you're not equipped for strip tillage or twin rows, you can still have low risk: Following conventional tillage (15), Georgia-03L peanuts (15) are planted in single rows (15) on May 12 (5) using Thimet in the furrow (5) with a final stand of 4.6 plants per foot of row (5). No Classic herbicide is applied (0). Risk Index = 60 If you ignore all the known methods to minimize spotted wilt: Following conventional tillage (15), SunOleic 97R peanuts (50) are planted in single rows (15) on April 20 (25) using no at-plant insecticide treatment (15) with a final stand of 2.2 plants per foot of row (25). Classic herbicide is applied (5). Risk Index = 155 |
