Abstract
Experiment results showed that Imazalil(500g/L) emulsifiable concentuates(EC) had a significant role in inhibiting Penicillium italicum Wehmer and Penicillium digitatum Saec on orange.The EC_(50) of Imazalil on P.italicum and P.digitatum was 0.0136mg/kg and 0.0129mg/kg respectively.When oranges were dipped into the liquid with Imazalil 400~800mg/kg for 1 min,then dried and encased,and maintained under natural conditions for 60 days,the inhibiting effect on P.italicum and P.digitatum was 93.11%~96.48%,which was significantly higher than that with 600mg/kg of 70% Thiophanate-methyl(84.30%).During orange storage Imazalil did not produce harmful effect on color,luster and taste of oranges.
