[en] Fusarium crown and root rot (FCRR) of asparagus (Asparagus officinalis L.), with a complex etiology including several Fusarium spp., and Fusarium wilt (FW) of tomato (Solanum lycopersicum L.), caused by Fusarium oxysporum f. sp. lycopersici (Fol), occur in most growing areas of the world and can cause serious economic losses. Its control is difficult due to the long survival of pathogens in the soil and their easy spreading by propagation material. In addition, asparagus cultivars available often have low resistance levels and, due to the wide genetic diversity within species of Fusarium pathogenic of asparagus, implementation of resistance is difficult to develop. On the other hand, tomato cultivars resistant to Fusarium have been available for decades and provide a certain degree of control, but the emergence and development of new pathogenic races is a constant problem. In fact, commercially acceptable varieties of tomato with complete resistance are not frequent. Therefore, there are few chemical control options available for the management of these diseases. A sustainable and environmentally friendly alternative is the use of organic soil amendments that can greatly reduce the impact of soilborne plant pathogens (Lazarovits, 2001; Noble y Coventry, 2005; Bonanomi et al., 2007; Melero-Vara et al., 2011). This work has been conducted in the framework of organic farming since organic by-products from agricultural and fishing industries in the area (poultry manure, commercial pellet of poultry manure, olive residue compost and fish emulsion) have been tested as organic soil amendments aiming disease control for the pathosystems Fusarium spp./asparagus and Fusarium oxysporum f. sp. lycopersici / tomato.

[es] La Podredumbre de ra&iacute;ces y corona (PRC) del esp&aacute;rrago (Asparagus officinalis L.), de etiolog&iacute;a compleja, incluyendo varias especies de Fusarium, y la Fusariosis vascular (FV) del tomate (Solanum lycopersicum L.) ocasionada por Fusarium oxysporum f. sp. lycopersici (Fol), est&aacute;n presentes en la mayor&iacute;a de las zonas de cultivo del mundo y causan graves p&eacute;rdidas econ&oacute;micas. Su control es dif&iacute;cil debido a la prolongada supervivencia de los pat&oacute;genos en el suelo y su f&aacute;cil diseminaci&oacute;n con el material de propagaci&oacute;n. Adem&aacute;s, los cultivares de esp&aacute;rrago suelen tener escasa resistencia, que es dif&iacute;cil de implementar por la amplia diversidad gen&eacute;tica dentro de las especies de Fusarium patog&eacute;nicas de esp&aacute;rrago y, aunque los cultivares de tomate resistentes a la Fusariosis han estado disponibles desde hace d&eacute;cadas y proporcionan un cierto grado de control, la aparici&oacute;n y desarrollo de nuevas razas patog&eacute;nicas supone un problema constante. De hecho, no existen variedades de tomate comercialmente aceptables con una resistencia suficiente. Para el manejo de estas enfermedades hay pocas opciones de control qu&iacute;mico disponibles. Una alternativa sostenible y ecol&oacute;gica es el uso de enmiendas org&aacute;nicas de suelo, que pueden reducir el impacto de hongos de suelo fitopat&oacute;genos (Lazarovits, 2001; Noble y Coventry, 2005; Bonanomi et al., 2007; Melero-Vara et al., 2011). Este trabajo se ha realizado en el marco de una agricultura ecol&oacute;gica, utiliz&aacute;ndose residuos org&aacute;nicos de la industria agr&iacute;cola y pesquera de la zona (gallinaza, pellet comercial de gallinaza, compost de alpeorujo y emulsi&oacute;n de pescado) como enmiendas org&aacute;nicas de suelo en ambos patosistemas Fusarium spp./esp&aacute;rrago y Fusarium oxysporum f. sp. lycopersici / tomate.
