Inspire EC^® is a new cotton harvest aid currently being developed by Syngenta Crop Protection, Inc. The active ingredient butafenacil is a member of the protoporphyrinogen oxidase (PPO) inhibitor class of chemistry. The product will be formulated as an emulsifiable concentrate containing 0.83 pounds of active ingredient per gallon. As a cotton harvest aid, Inspire EC causes cell membrane disruption and a release of ethylene in the cotton leaf. Leaf defoliation begins within 7 days after application. Inspire EC has proven to be an effective cotton harvest aid material in trials established by Syngenta and university researchers across the cotton belt. An added benefit of Inspire EC is its effectiveness in desiccating vines that may be present at harvest.
