Abstract:

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.

Key words: pesticide, chemical control, disease, insect, weed, requirement

摘要：

在21世纪，农药的发展显著受到生态环境保护的制约。随着加入WTO、农业结构的调整、转基因作物的不断问世、节水技术的发展以及外来生物的入侵，病虫草害正在发生着重大的变化，这些变化需要化学防治技术的革新，也对中国的农药工业提出了新的需求。在新世纪，有害生物的化学防治策略也有很大的转变，环境相容的农药品种也在不断地推向市场，防治技术也有很大的提高。因此，在未来50年，化学农药仍将继续发展并仍得广泛地应用。
