我国城市园林植物病虫害的现状及对策

Current situation and countermeasures of urban garden plant pests in China

近年来 ,城市园林绿化格局的大调整、不合理的植物配置、城市生态恶化以及一些国外病虫的不断传入改变了环境植物病虫害的发生和危害。因此 ,在防治战略上要变短期行为为可持续发展 ,在防治战术上要变单纯打药杀灭为预防为主 ,综合治理 ,在防治效果及业绩评价上要变以彻底消灭为主为有虫不成灾 ,注意植物间的他感作用 。

The occurrence and damage of environmental plant pests have been changed in recent years by reason of the adjustment of urban garden greening patterns,unreasonable disposition of plants,deterioration of urban ecological environment and continuous introduction of foreign pests.So its suggested that the control strategy be changed from short term behavior to sustainable development,tactics be changed from simple application of pesticides to prevention first and integrated management,attention be paid on interaction among plants and mutual promotion in plant protection be encouraged.
