Finish™ Cotton Harvest-Aid

C. David Fritz


FINISH™ (EXP-31039) consists of two molecules: RPA90946 [1-(2,4-dichlorophenylaminocarbonyl)-cyclopropane carboxylic acid] common name cyclanilide which is a new class of chemistry and Ethephon [(2-chloroethyl phosphonic) acid]. EXP-31039 is currently under development as a cotton harvest-aid product by Rhone-Poulenc Ag Co.


cyclanilide is the approved common name for RPA90946: C.A.S. registry number 113136-77-9.

Field evaluations of the ethephon + RPA90946 combination in replicated small plot crop destruct trials have been continuing since 1988. The focus of this research has been the development of a single package cotton harvest-aid product that addresses the three key areas related to preparing cotton for machine harvest: (1) removal of leaves, (2) opening of mature bolls, and (3) the prevention or inhibition of foliage regrowth.
