Plant diseases and their diagnoses are currently one of the global challenges and causes significant impact to the economy of farmers and industries depending on plant-based products. Plant pathogens such as viruses, bacteria, fungi, and pollution caused by the nanomaterial, as well other important elements of pollution, are the main reason for the loss of plants in agriculture and in forest ecosystems. Presently, various techniques are used to detect pathogens in trees, which includes DNA-based techniques, as well as other microscopy based identification and detection. However, these methodologies require complex instruments and time. Lately, nanomaterial-based new biosensing systems for early detection of diseases, with specificity and sensitivity, are developed and applied. This review highlights the nanomaterial-based biosensing methods of disease detection. Precise and time effective identification of plant pathogens will help to reduce losses in agriculture and forestry. This review focuses on various plant diseases and the requirements for a reliable, fast, and cost-effective testing method, as well as new biosensing technologies for the detection of diseases of field plants in forests at early stages of their growth.
植物病害及其诊断是当前全球面临的挑战之一，对依赖植物产品的农民和产业经济造成了重大影响。植物病原体，如病毒、细菌、真菌以及纳米材料污染和其他重要的污染因素，是导致农业和森林生态系统中植物损失的主要原因。目前，已经有多种技术用于检测树木中的病原体，包括基于 DNA 的技术，以及其他基于显微镜的鉴定和检测方法。然而，这些方法需要复杂的仪器和时间。最近，已经开发和应用了基于纳米材料的新型生物传感系统，用于早期、特异性和敏感性地检测疾病。本综述重点介绍了基于纳米材料的疾病检测生物传感方法。精确和及时地识别植物病原体将有助于减少农业和林业的损失。本综述重点介绍了各种植物病害以及对可靠、快速和具有成本效益的测试方法的要求，以及用于在森林中早期检测田间植物病害的新型生物传感技术。
