Abstract: To explore the control effect of acidic electrolyzed functional water against tomato leaf mould, we sprayed different concentration of acidic electrolyzed water in seedling recovering period and early stage of the disease and used 1×106 spores/g Pythium oligadrum as control pesticide. The results showed that it could not only control the disease but also raise the production when 50 mg/L acidic electrolyzed functional water was used once a week in seedling recovering stage and 80 mg/L was sprayed once a week and lasted for three weeks in the early stage of the disease. However, if 80 mg/L was only used in the preliminary stage of disease without any treatment in the seedling recovering period, it had control efficiency on the disease, but had no obvious effect on the production.
