SUMMARY In laboratory trials, fumigation with acetaldehyde vapour at 0–75 to 20 % concentration (v/v) for 0–5 to 120 min at 21 o C killed six species of post‐harvest citrus pathogens grown on agar media. The fungicidal effect of acetaldehyde vapour at this temperature was a function of concentration and exposure. Penicillium digitatum and P. italicum were not as susceptible to inhibition of spore germination as Alternaria citri, A. tenuis, Colletotrichum gloeosporioides and Glomerella cingulata. A concentration of 10 % acetaldehyde vapour at 21 o C for 10 min was fungitoxic to all the pathogens tested.
