Abstract:
Taking tomato variety 09888 which was susceptible to tomato powder mildew as material，the induced resistance of different concentrations of β-amino butyric acid (BABA)，benzothiadiazole (BTH)，chitin sugar (CTS) and potassium silicate(K2SiO3) to tomato powder mildew were investigated.Four chemicals were spraying at seedling stage and then the whole plant was inoculated with powdery mildew.The results showed that the inductive effect of BABA and BTH were the most obvious and the biggest relative cure effect were 67.50% and 64.00% respectively.BABA and BTH can induce tomato resistant to powdery mildew and improve the activities of disease-related enzymes，such as catalase (CAT) and peroxidase (POD).The effects of 500 mg/L BABA and 50 mg/L BTH were significantly better than others.
