Nitrogen is the key component in mineral fertilizers applied to citrus groves. N has more influence on tree growth, appearance, and fruit production/quality than any other mineral element. Nitrogen affects the absorption and distribution of practically all other elements, and it is particularly important to the tree during flowering and fruit set.

Informacion para los propietarios: Cancro Citrico (PP298)
El cancro cítrico es una enfermedad introducida en Florida y es muy perjudicial económicamente para la industria comercial. La enfermedad no está presente en todas las regiones tropicales y subtropicales productoras de cítricos donde el cancro cítrico puede ser problemático, por lo tanto, las restricciones para exportar fruta con cancro cítrico son muy estrictas. Esta enfermedad también concierne a los propietarios, no solo por sus efectos en la industria económica, sino también porque es altamente contagiosa y la mayoría de la fruta contagiada en un árbol muy afectado se cae de éste prematuramente. This 4-page fact sheet was written by M. M. Dewdney, P. D. Roberts, J. H. Graham, K. R. Chung, and M. Zekri, and published by the UF Department of Plant Pathology, January 2013.

Identificacion de los sintomas del cancro citrico y procedimientos de descontaminacion (PP214SP/PP138)
El cancro cítrico es una seria enfermedad de los cítricos. La mayoría de los cultivos de cítricos son susceptibles, la toronja, la lima mejicana y algunas naranjas tempranas son las más susceptibles. Una infección severa puede causar defoliación, una muerte regresiva de la rama, una decadencia general del árbol, una caída prematura de la fruta, y manchas en la misma. Los árboles severamente infectados se vuelven débiles, improductivos y no rentables.
