Abstract： In order to study the effects of different concentrations of multi-effect azole on the cold tolerance of strawberry，strawberry leaves were sprayed with 40， 80，120， 160， 200， 240mg/kg multi-effect azole with clear water as control（CK）. Strawberry plants were treated at low temperature of 3～-15℃. According to the relative conductance and Logistic equation，the semi-lethal temperature（LT50）was obtained. At the same time，the field freezing injury index and mortality were measured. The results showed that the semi-conductivity death temperature of 7 treated strawberry leaves was 120mg/L（-9.00℃）

Key words： Strawberry; Multi-effect azole; Relative conductivity; Half lethal temperature; Cold tolerance
