辣椒疫霉(Phytophthora capsici)是一种重要的植物病原卵菌,寄主范围广泛,除了辣椒以外,还可以侵染番茄、茄子及多种瓜类,造成疫病,危害作物生产。随着设施农业的大规模发展,蔬菜种植面积日益扩大,该菌所致病害及造成的经济损失逐年加重。对辣椒疫霉菌进行早期检测可以及时采取防治措施,控制病害进一步扩展。而传统的检测方法主要为直接观察发病症状、病原物分离后进行形态鉴定,费时费力,不适合于病原物的早期快速鉴 Phytophthora capsici is an important phytopathogenic oomycete with a wide range of hosts. In addition to pepper, it can also infect tomatoes, eggplants and various melons, causing disease and endangering crop production. With the large-scale development of facilities and agriculture, the planting area of ​​vegetables is expanding day by day, and the disease caused by the bacteria and the economic loss are increasing year by year. Early detection of Phytophthora capsici can take timely control measures to control the disease to further expand. The traditional detection methods mainly for the direct observation of the onset of symptoms, pathogens after the separation of morphological identification, time-consuming and laborious, not suitable for the early rapid pathogen Kam
