Breeders always seek for new mandarin-type cultivars with distinctive and valuable characteristics. This study allows the characterization of the cultivars under study from a chemotaxonomic point of view, providing valuable data on their nutraceutical properties.

Since its appearance two centuries ago, the disease known as tristeza, is considered the most devastating virus-related illness of the citrus industry worldwide. Citrus tristeza virus (CTV), the causing agent of the disease, is transmitted by graft or by aphids. Here, we report the results of the biological, molecular and evolutionary full-genome characterization of the most relevant genotypes in the country.

Citrus tristeza virus (CTV) (Closteroviridae:Ampelovirus) is the pathogen of viral origin that causes more economic losses to the cultivation of citrus fruits. These preliminary results demonstrate the importance of studying tristeza disease situation in the current context of Cuban citriculture due to the threat of the emergence of a new epidemic and to update management strategies for the disease.

Semiochemicals, such as pheromones and volatiles form plant hosts, provide sustainable and eco-friendly tools to be included in integrated pest management programs of many insects. Uruguayan citriculture is majorly aimed for the international trade of fresh fruit, where the allowed limits of pesticide residues are important limitations.

RESUMEN. El rayado tanto en los cítricos como en otras especies frutales, es una práctica cultural utilizada con frecuencia para modificar su respuesta productiva. Si bien sus efectos directos han sido ampliamente descritos, poco es sabido acerca de su mejor época de realización, respuesta de las diferentes variedades, de los efectos negativos que puede inducir, así como los mecanismos de defensa subyacentes que se activan para mitigarlos. ABSTRACT. Girdling in both citrus and other fruit species is a cultural practice often used to modify its productive response.

En nuestro país Citrus tristeza virus (CTV) es endémico. Fue detectado en más del 90% de las plantas en relevamientos recientes de montes comerciales.

El cancro bacteriano del tomate causado por Clavibacter michiganensis subsp. michiganensis (Cmm) es considerada la enfermedad más importante de este cultivo a nivel mundial. En Uruguay, ha habido epidemias severas de esta enfermedad en los últimos años, causando importantes pérdidas económicas.
