16 Do current cultivars have sufficient TSWV resistance to minimize risk of early planting? Not without combining with other risk factors Thimet Plant stand 4/foot Twin rows Resistant cultivar ( points or less) Why?

25 Georgia-12Y Georgia-06G How would I manage: Variety Planting Thimet Twin Rows May 1-31 if planting earlier than May Yes, especially if planting before May White mold program Early season Yes, especially if planting early Mid season May need more than folicur if weather conditions warrant: Convoy, Elatus, Fontelis, Alto+Abound, Evito, Provost,etc. Leaf spot program Bravo and Folicur (or generic equivalents) are okay espeically if rotation is 2 years or more April 15- May 31 if planting earlier than May Probably not needed for spotted wilt control May not be needed Okay with Bravo and Folicur (or generic equivalents), especially if rotation is 2 years or more Bravo and Folicur (or generic equivalents) are okay especially if rotation is 2 years or more

26 Georgia-13M Georgia-09B How would I manage: Variety Planting Thimet Twin Rows White mold program Early season Mid season Leaf spot program May - 31 use on all plantings Yes, especially if planting before May Yes, especially if planting early Will likely benefit from Convoy, Elatus for WM control Will likely benefit from fungicides with better activitiy on LS: Priaxor, Elatus, Alto+Abound, Fontelis, Evito, Provost, etc. April 15- May 25 if planting earlier than May Yes, especially if planting before May Yes, especially if planting early Will likely benefit from Convoy, Elatus for WM control Need to use fungicides with better activitiy on LS: Priaxor, Elatus, Alto+Abound, Fontelis,, Evito, Provost, etc

27 TUFRunner 297 TUFRunner 511 Variety Planting May - 25 May 1-25 How would I manage: Thimet Twin Rows use on all plantings if planting earlier than May White mold program Early season Yes, Probably especially if planting before May needed only if high risk of white mold Yes, Probably especially if needed only planting if high risk of before May white mold Mid season Probably okay with Bravo and Folicur (or generic equivalents), especially if rotation is 2 years or more Probably okay with Bravo and Folicur (or generic equivalents), especially if rotation is 2 years or more Leaf spot program Need to use fungicides with better activitiy on LS: Priaxor, Elatus, Alto+Abound, Fontelis, Evito, Provost, etc If risk is high, will benefit from fungicides with better activitiy on LS: Priaxor, Elatus, Alto+Abound, Fontelis, Evito, Provost, etc. If risk is low, may be okay with Bravo,

28 Georgia-14N Tifguard How would I manage: Variety Planting Thimet Twin Rows May 1- May 31 if planting earlier than May Yes, especially if planting before May White mold program Early season Mid season Probably needed only if high risk of white mold Probably okay with Bravo and Folicur (or generic equivalents), especially if rotation is 2 years or more Leaf spot program Bravo and Folicur (or generic equivalents) are okay espeically if rotation is 2 years or more May 1- May 31 if planting earlier than May Yes, especially if planting before May Probably needed only if high risk of white mold Probably okay with Bravo and Folicur (or generic equivalents), especially if rotation is 2 years or more Bravo and Folicur (or generic equivalents) are okay espeically if rotation is 2 years or more
