Shanghai Chenshan Botanical Garden (CBGS) is a new one in the global botanical gardens system, which is focused on botanical research, plant collection and public education. In CBGB, there are more than three thousand of plant species and at least six thousand of cultivars were planted. Therefore, the diseases and pests are also in a large amount. Facing to so rich plants and the status of so many visitors, in order to control the disease without harm to both plants and visitors, the pollutionfree agricultural chemicals are necessary to be used in this garden. The using of nonpolluted agrichemicals is still the start in CBGS now. A planning was confirmed by horticulture department of CBGS. According to the planning, we gave a list of pollutionfree agricultural chemicals, including biological pesticide, mineralbased pesticide and organic synthesize pesticide. There are 30 kinds of nonpolluted agrichemicals were listed, fourteen of them are biological pesticide, two is mineralbased pesticide, while the other fourteen are organic synthesize pesticide.
