On account of pests and diseases in greenhouse, solar cells were used for energy. Ozone was generated by corona discharge during the day which used to kill bacteria, viruses, fungi in greenhouse. Use the phototaxis lure insects with blue-violet LED, high power electrical shock to kill flying insects in the evening. Thereby reduces crop diseases and pests and reduces pesticide use. Greenhouse diseases and pests therapeutic instrument of solar consist of power supply module, ozone generator module, high voltage pest control modules. Paper focuses on the principles of the design, tentative design, function test and measurement data analysis.
