Abstract

Application of TP as Tipimon® or TPA as Maxim® at the young fruitlet stage significantly increased yield in three lychee ( Litchi chinensis Sonn.) cultivars: `Mauritius', `Floridian', and `Kaimana'. Application of TP followed by TPA a week later increased yield more than did either substance alone. In all experiments, TPA increased fruit size and weight, relative to both controls and TP-treated trees. The increased yield did not prevent the increase in fruit size. Use of sprays of TPA may be an effective way of satisfying the market demand for large lychee fruit. Chemical names used: 2,4,5-trichlorophenoxypropionic acid (TP); 3,5,6-trichloro-2-pyridyloxyacetic acid (TPA).
