​This presentation begins by asking “How did we get here?” and identifying factors underlying the current bollworm situation: sharing Cry proteins among hosts; Cry proteins not being “high dose” for bollworms; and low refuge compliance. Discussion then covers bollworm scouting in cotton; neonates in three-gene cotton; foliar insecticide performance; effects on yield; and Vip technology. The presentation ends by making recommendations for cotton producers.
