For the pests control on crops, we can use friendly non synthetic chemicals, combined farm management, field monitoring and other technologies to design a workable integrated pests management (IPM) strategies. Achieve the purpose of producing fruits and vegetables without synthetic pesticides. The first, by preventing the pest invasion ways that are five: loopholes on net house, Resident pests, The foreign medium, Carried by seedlings and Carried by human and farm tools. In addition, by field monitoring, early detection of invasive pests is also the focus of work. According to the species and abundance of pests, the appropriate control methods and intensity can be adjusted to work in time. Hanging yellow sticky paper after planting can play monitoring and assisted control. The powdery mildew and smaller body size pests as aphids, spider mites, silver leaf white fly etc. will be slow down if spray "vegetable oil mixture" or "emulsified sunflower oil" 400-500 folds of water dilution weekly. However, all of above acts are intended to fulfill the spirit of prevention rather than treatment, early detection and early treatment. The synthetic pesticides can be really gotten rid of in many crop pests management.
Key words: Non Synthetic Chemicals, IPM, Net House.
