Physcion can induce plant resistance to disease, and is registered to control powdery mildew by spraying in China. Seed coating is a widely applied precision method for pest prevention and control. To explore its potential in disease control and yield increase by seed coating, mixtures containing physcion and commonly used fungicides were designed and applied in a field trial. Greenhouse experiments screened the optimal concentration of physcion for seed coating an found it to be 1:50, with excellent promotion of plant growth and powdery mildew control. In field trials, seeds coated with a combinations of physcion with validamycin and pyrimidine nucleotide (2#) at 1:50 exhibited the highest emergence rate, tillering number, control effect of wheat powdery mildew, enzyme activity of ascorbate peroxidase (APX), glutathione reductase (GR), and peroxidase (POD), photosynthetic pigment content, and yield. These results provide an effective approach to wheat disease control and yield increase in wheat fields, and can lay the basis for reasonable application of physcion in Huang-huai-hai plain in China.
