对西欧四国的植保政策的调查表明:他们都希望在未来的农业生产中减少农药的使用,但在最终减少农药用量的措施上彼此存在差异。瑞典已成功地制定了将农药使用量减少50％的计划,荷兰正在执行这样一个计划;法国试图实现一种监督指导下的病虫害防治;而西班牙则旨在减少出口产品中的农药残留,在2000年前,只有荷兰可望大量地减少农药的使用量。难于减少对农药及农药使用的依赖的原因有:没有新的防治方法,研究力量不足,执行监督不足,国家没有明确的法规和缺乏欧共体政策。
Surveys of plant protection policies in four Western European countries have shown that they all want to reduce the use of pesticides in future agricultural production, but differ from each other in the eventual reduction of pesticide use. Sweden has succeeded in developing a plan to reduce pesticide use by 50%. The Netherlands is implementing such a plan. France is trying to achieve a supervision and control of pests and diseases. Spain, on the other hand, aims to reduce pesticide residues in exported products in 2000 Years ago, only the Netherlands was expected to significantly reduce the use of pesticides. Difficult to reduce the dependence on pesticides and pesticides use are: there is no new prevention and treatment methods, lack of research strength, lack of implementation supervision, the state does not have clear laws and regulations and the lack of EC policy.
