AbstractTwo rates of the ethylene blocker ReTain® were evaluated on four varieties of cotton in the Palo Verde Valley during the summer of 2005. Data indicated that responses to ReTain® varied greatly by variety. Application of ReTain® to DPL 555BR resulted in significant increases in numbers of fruiting structures per plant, however, these increases were not realized at harvest, as ReTain® treatments resulted in numerically reduced yields for this variety. Bolls per plant at harvest were not signficantly different for DPL 449BR, DPL 5415R or STV 5599BR. Both rates of ReTain® significantly increased uniformity of DPL 555BR cotton lint, but the lower rate of ReTain® evaluated usually resulted in slightly higher cotton lint quality for most components measured than did the higher rate. Quality and yield data were not collected for DPL 449BR, DPL 5415R or STV 5599BR.
