Peracetic acid and chlorine dioxide for postharvest control of Monilinia laxa in stone fruits.

The effects of different concentrations of peracetic acid (PAA; 62.5, 125, 250, 500, and 1,000 micrograms/ml) and chlorine dioxide (ClO(2); 12.5, 25, 50, 100, and 200 micrograms/ml) on germination of Monilinia laxa conidia were tested. Conidia germination was related to the concentration of chemical product used, as well as duration of treatment. Complete inhibition of germination was observed with PAA at 500 micrograms/ml after 5 min of contact with conidia and with ClO(2) at 50 micrograms/ml after 1 min of contact with conidia. The results of in vitro tests were confirmed by inoculation of fruits with treated conidia. The PAA treatment also was effective 1 h after pathogen inoculation but only on plums, for which a 1,000 micrograms/ml treatment significantly reduced decay incidence by 50%. In a semi-commercial test, pathogen conidia dipped for 20 min in PAA at 250 micrograms/ml or ClO(2) at 10 micrograms/ml or for 5 mm in PAA at 250 micrograms/ml were completely inhibited, and no brown rot was observed in inoculated wounded nectarines and plums.
