Abstract：Onion oil and garlic extraction were studied to test the inhibitory action on conidia germination,mycelium development and the control effect on gray mold disease with strawberry fruits.The results showed that onion oil of 0.5 g?L-1 and garlic extraction of 200 g?L-1 were effective enough to control conidia germination.In another experiment,after 24 h,onion oil of 0.5 g?L-1 and garlic extraction of 100 g?L-1 could effectively inhibit mycelium growth,the inhibitory rates(IRs)were 89.3 % and 85.9 % respectively.After 48 h,the effective concentrations of onion oil and garlic extraction were 2.0 g?L-1 and 200 g?L-1,the related IRs were 90.5 % and 85.6 %.Onion oil and garlic extraction didn’t work well to control gray mold.At the same time,we found that chemical fungicide(Seibear)showed better control efficiency against gray mold and inhibitory action on fungal mycelium development.But it didn’t express effective action on fungal conidia germination.
