We Investigated the species of diseases and insect pests, species of natural enemies, distribution and dominant species in export vegetable bases in Shandong Province. Dynamics of main diseases and insect pests were studied.2. We investigated the main control technologies for diseases and insect pests, types and application methods of pesticides.3. Effects of crop varieties, fertilities and cultivation on diseases and insect pests, production and pesticide residues were examined.4. Control effects and application technologies of frequency trembler grid lamps, greenhouse ozone machine and insect-proof net were tested.5. By research, seven biological preparations and twelve chemical pesticides with high activity, low toxicity and low residue were screened.
