    With the improvement of diagnostic technology for diseases and deepening for exploring natural environ ment, as well as the evolution of pathogenic microbiology, old animal diseases prevail frequently and new animal  diseases emerge from time to time. To enforce new viewpoint of controlling zoonosis, that is to take measure of controlling zoonosis before diseases attacking human, the fundamental control measure is ecological reconstruction in the natural diseases field. We should improve the recognition of effect of animal in controlling zoonosis, and emphasis that animal sanitation and control of animal diseases play key role in preventing the human disease. In z oonosis, the role of animal may be the origin of emerging and development of diseases, meanwhile, it is also the endpoint of diseases. If animal pathogen could not be effectively controlled and purified, it seems very difficult for protecting ourselves. In other words, human and animal play equal role in controlling zoonosis, and sometimes, animal may be play more important role on it. In order to control measures for zoonosis, the ability of diagnostic diseases and vaccine production must be improved and anti-virus drug for treating virus zoonosis should be developed.

    According to the developing facts both in China and the world, the basic countermeasures have been suggested in the area of cereal security: ① Set up the National Cereal Security Committee, so as to coordinate the relationship among different departments and layers, lead the organizational structure founded to complete the national strategic task in cereal production, and take direct action finally; ② Draw up the Cereal Security Act, and then to management cereal production according to the law, construct the structure of cereal production system gradually, which is stable, ideal, and fitting whole social benefit; ③ Implement the system of cereal balance between demand and supply again, and the system is charge by mayor in province level, to set up an cooperating mechanism between major production regions and main consumption areas of cereal, therefore, form an reliable fundament in national cereal security; ④ Construct a cereal market management system separately, to deal with the problems like cereal storage, market price in and out of China; ⑤ Improve the infrastracture of cereal production and knowledge of cereal producer; ⑥ Build up the cropping system with the components of cereal crop, feedstuff crop as well as cash crop, and develop the cereal-saving animal industry.

    The development of pesticide is greatly restricted by the protection of the environment in the new century. Along with the joining of the WTO, the adjustment of agricultural crop components, breeding of transgenic crops, extension of water saving technologies and invasive alien species, there are greatly changes in the diseases, insect pests and weeds. These changes require renovation of chemical control technologies, as well as pesticide industry. There is a large transformation on control strategy of pests in the new century. New pesticides that are environment friendly are putting into market and technologies of chemical control are improved. Therefore, the chemical pesti- cide will be developed continuously and applied widely in the next 50 years.
