理想的作物保护应该经济、安全地防止害虫、疾病和杂草的破坏性影响，而不损害环境或引起后续的控制问题。目前的方法，主要是基于农药和抗性作物品种，有效地控制许多有害生物，但有重要的局限性。最严重的问题可能是容易出现耐受性害虫或病原体;化学方法的选择性也往往不足，而且非常浪费。然而，对这些方法的依赖将继续存在，因此必须设法尽量减少其缺陷。改进的前景进行了讨论，需要更好的情报虫害及其后果，需要确保控制措施仍然有效，需要提高作物保护剂的利用效率。实施改进建议可能需要从根本上改变作物保护做法的组织。
Ideally crop protection should prevent damaging effects of pests, diseases and weeds economically, safely and without harming the environment or inducing subsequent control problems. Present methods, based mainly on pesticides and resistant crop varieties, control many damaging organisms effectively but have important limitations. Vulnerability to the emergence of tolerant strains of pest or pathogen is probably the most severe; chemical methods are also often insufficiently selective and very wasteful. Dependence on these methods will continue, however, and it is therefore essential to seek ways of minimizing their deficiencies. The prospects for improvement are discussed in relation to the need for better intelligence about infestations and their consequences, the need to ensure that control measures remain effective and the need to improve the efficiency of utilization of crop protection agents. Implementation of the suggestions for improvement could require fundamental changes in the organization of crop protection practices.
