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?

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
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
