Method of defoliating crop plants and minimizing regrowth Following defoliation, and plant composition for defoliating crop plants and minimizing plant regrowth.
Concurrent or sequential application of an auxin transport inhibitor and a defoliating agent synergistically improve defoliation of crop plants and minimize crop plant regrowth. Preferably, the auxin transport inhibitor is a semicarbazone compound. The defoliating agent may be an ethylene response or ethylene-type response agent such as a phosphonic acid derivative. Most preferably, the semicarbazone compound is diflufenzopyr and the phosphonic acid derivative is ethephon (i.e., ethephon (2-chloroethyl) phosphonic acid).
