有害生物综合治理：采用多种战术协调进行，以便把有害生物的群体控制在造成经济损失允许水平之下，同时不给人类健康、作物、家畜、野生生物资源和环境造成危害。IPM是英文Integreted Pest Management的缩写，中文意思是“有害生物综合治理”。这里所谓的“有害生物”包括对农作物生产造成损失的所有病菌（含病毒、线虫类）、害虫（含软体动物类）、杂草、鸟类、鼠类等各种生物因子，广义上也包括引起非侵染性病害的各种非生物因子，如有毒气体、土壤毒素、冷害等环境因子。 IPM概念强调只有在有害生物的危害会导致经济损失的前提下才进行防治，也就是说，允许作物上存在一定数量的病菌或害虫，只要它们的种群数量不足以达到经济危害水平，就不必进行防治。另外，在IPM的实践中，非常重视包括抗性品种、栽培措施、生物天敌、化学药剂在内的综合防治技术的应用，尤其是利用天敌等生物控制因子来控制病虫害，对化学农药的施用采取慎重的态度。其主要内容是：从农业生态系整体观念出发，全面考虑作物的整个生育期主要病虫害，结合地区特点和耕作栽培制度，因地制宜地制定农业的、生物的、化学的防治措施，协调运用，最大限度地发挥自然控害因子的作用，将病虫害控制在经济允许水平之下，保证农作物优质、高产、稳产，提高经济、生态和社会三大效益。

Integrated Pest Management (IPM) is an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM programs use current, comprehensive information on the life cycles of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.The IPM approach can be applied to both agricultural and non-agricultural settings, such as the home, garden, and workplace. IPM takes advantage of all appropriate pest management options including, but not limited to, the judicious use of pesticides. In contrast, organic food production applies many of the same concepts as IPM but limits the use of pesticides to those that are produced from natural sources, as opposed to synthetic chemicals. IPM is not a single pest control method but, rather, a series of pest management evaluations, decisions and controls. In practicing IPM, growers who are aware of the potential for pest infestation follow a four-tiered approach. The four steps include: Set Action Thresholds，Monitor and Identify Pests，Prevention and Control
