The theme of the Symposium was the Development of Insecticide under the Zero-growth Policy for Pesticides. Prof. YUAN Huizhu, the secretary of Working Committee of Extension of Plant Protection Products chaired the opening ceremony.

DDG ZHENG Yongquan thanked the experts and officials who were present at the Symposium on behalf of organizers of the Symposium and greeted the participants. He said in his address that since the first exchange symposium for insecticides used in rice was held in Changsha, Hunan Province, in 2011, several similar exchange symposia had been held for the development, extension and application of insecticides, fungicides and herbicides. Such, it formed series special exchange symposia, with the due authority, for plant protection products. This year, he said, the Working Committee of Extension of Plant Protection Products organized, together with co-organizers, the 2nd Exchange Symposium for Insecticide Development, Extension and Application to continue with the analyzing and probing the current status quo and future trend of insecticides, exchange the experience in insecticide R&D, production, marketing and application, and speed up the extension and application of new products and new techniques. Facing issues in the increasing difficulties in development of novel insecticides, increasing of insect resistance due to unreasonable use of pesticides, the complicated of and changing in the occurrence of crop diseases and insect pests, and profound impact brought about by zero-growth policy for pesticides, the organization of this Symposium provided a good platform for colleagues in the industry to communicate.
