The aliphatic alcohols 1-nonanol, 1-decanol and especially 1-octanol exhibited the highest activities, as assayed by all the methods used. The terpenoid compounds perillalcohol, perillaldehyde, citral, terpineol, carveol and citronellol, as well as the reference aromatic compound cinnamaldehyde also exhibited high activity against P. digitatum. Neither hydrocarbons nor esters inhibited this fungus. The mode of action of 1-octanol, perillaldehyde, citral, perillalcohol and terpineol against P. digitatum was fungicidal, whereas 1-decanol, 1-nonanol, carveol and citronellol were only fungistatic. Application of biocidal formulations comprising 1-octanol and citral either separately or together inhibited decay of P. digitatum-inoculated lemons for three weeks after inoculation.
