| Abstract | Pycnidiospores of Botryodiplodia theobromae Pat. germinated within 5 h on solid media. The rate and amount of germination in liquid media were lower than on solid media. Near maximum germination occurred over the range 15–42 °C and at 100% relative humidity. Light, which is essential for pycnidium production, had no effect on germination. Five fungicides (Dinocap (Karathane WD), Pano-drench, Bordeaux mixture, Captan, and copper sulphate) commonly applied to fruits, and four potato sprout suppressants (diethylene glycol monobutyl ether, ethylene glycol monobutyl ether, n-amyl and isoamyl alcohol), at concentrations ranging from 0.001% to 2.5%, inhibited germination and germ-tube growth. The potential use of the germination inhibitors as protectants against Botryodiplodia theobromae rot is discussed. |
