The early detection of plant pathogens is an appropriate preventive strategy for the management of crop yield and quality. For this reason, effective diagnostic techniques and tools, which are simple, specific, rapid and economic, are needed to be developed. Although several such technologies have been developed still most of them suffer one or the other limitation. Major limitations of the widely used diagnostic methods are requirement of trained staff and laboratory setup. Development of point-of-care diagnostic devices (handy portable devices) that require no specialized staff and can directly be used in fields is need of the hour. The aim of this review is to compile the information on current promising techniques that are in use for plant-pathogen diagnosis. Additionally, it focuses on the latest in-field pathogen diagnostic techniques with associated advantages and limitations.

全面介绍目前用于田间植物病害诊断的技术。

植物病原体的早期检测是作物产量和质量管理的适当预防策略。为此，需要开发简单、特异性、快速和经济的有效诊断技术和工具。尽管已经开发了几种这样的技术，但它们中的大多数仍然受到一个或另一个限制。广泛使用的诊断方法的主要限制是需要经过培训的人员和实验室设置。开发不需要专门工作人员且可直接在现场使用的即时诊断设备（便携式便携式设备）是当务之急。本综述的目的是汇编有关当前用于植物病原体诊断的有前途技术的信息。此外，
