Applications of ethephon at rates from 300 to 500 ppm, applied when most of the basal figs had turned yellow, resulted in an earlier and more compact maturity period, without adverse effects to the crop. Earlier maturity in turn insured improvement of external and internal fig quality, without decreasing individual fruit weights. Ethephon is not registered for use on figs and is not recommended for use at this time by the University of California.
