Abstract: The biological pesticide and chemical pesticide control experiment demonstration, biological pesticide combination medication and general prevention technology integration and demonstration, the establishment of chemical pesticide reduction control display area were developed. Integrated technology system to reduce expansion application of chemical pesticide; gradually achieve chemical pesticide reduction technology standardization. The main varieties of three principals were determined： first was to choose low dosage, super-efficient, long efficient, low toxicity pesticides and bio pesticides; second was combination of medication, the overall control, improve the comprehensive benefit of single medication; third was mixed use, alternative medication to reduce disease and insect resistance, the control Cnaphalocrocis Medinalis and rice planthopper, borer, sheath blight, rice false smut and rice blast were determined, which greatly reduced the use of chemical pesticides in rice, protection of agricultural production safety, and achieved quality and safety of agricultural products and agricultural ecological security.
