SOTO-PLANCARTE, Alejandro et al. Methods for detecting Huanglongbing in citrus. Rev. Mex. Cienc. Agríc [online]. 2024, vol.15, n.4, e3300.  Epub Oct 14, 2024. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v15i4.3300.

In Mexico, citrus farming represents one of the most important economic activities for national fruit growing, with a production of 8.8 million tonnes and an economic spillover of more than 47 billion pesos per year. Nonetheless, production is affected by pests and diseases, with Huanglongbing (HLB), ‘yellow dragon’ or citrus greening, standing out as the most devastating disease worldwide, caused by a proteobacterium of the genus Candidatus Liberibacter (Ca. L.). Because there is no effective method to control this disease, correct and timely detection can significantly reduce its spread. The purpose of this review is to compile methods used for detecting the presence of Ca. L. in citrus plants, covering general aspects of the symptomatology of the disease, molecular methods for accurate and rapid detection when sampling both in plants and in the vector. In addition, different protocols are mentioned that analyze some compounds produced during infection with Ca. L. and images in citrus with HLB.

Keywords : diagnosis; images; PCR; sampling; spectrometry; symptoms.
