Inhibition of Patulin Production with the Insecticide Naled.

Patulin is a wide spectrum biocide produced by several species of Aspergillus , Penicillium and Byssochlamys , and is a potentially important mycotoxin that may be ingested by man. The effect of the insecticide naled on fungal growth and patulin production was evaluated using three concentrations (1, 10, and 100 mg/l, ppm) and several application times both before inoculation and during growth of the fungus. If added before inoculation, naled at 100 mg/l completely inhibited mycelial growth of Penicillium urticae for 15 days and patulin production for 30 days.
