Abstract : Chemical flower removal with Ethrel-48 (ethephon) at 0, 800 or 1600 p.p.m. was compared with manual removal on mango cv. Keitt trees. Hand thinning or application of Ethrel at 800 or 1600 p.p.m. increased the number of terminals with normal fruits compared with controls and yield was increased from 1924.4 g/10 panicles for controls to 3552.6 g and 4124.3 g by hand thinning and 800 p.p.m. Ethrel, respectively.
