Boll Weevil Eradication: Visit History of the Boll Weevil Eradication Program for an in depth history of the Boll weevil eradication program.

Eradication is accomplished by using boll weevil pheromone traps on all cotton fields within an eradication area to determine whether or not fields within an eradication area are infested. Fields that are infested are treated with ULV malathion insecticide treatments. During the early years of an eradication program the total number of insecticide treatments applied to control boll weevils may be somewhat higher than what growers would normally apply in the absence of an eradication program. However, as the eradication program progresses into the 4th and 5th years the number of treatments required declines sharply and reaches or approaches zero.
