    Manual de campo: enfermedades y plagas comunes del trigo
    (CIMMYT, 1977) Christensen, C.M.; Dubin, H.J.; Fuentes Fuentes, S.; Prescott, J.M.; Saari, E.E.
    El propósito del manual es el de ayudar a los técnicos agrícolas que trabajan en el campo a identificar las enfermedades y plagas comunes del trigo. No se dan aquí procedimientos específicos de control químico, puesto que estos pueden diferir de un país a otro. Se sugiere que se consulte a los fitopat61ogos y entomólogos locales en lo que atañe a las medidas específicas de control.

    Manuel des maladies: des ravageurs et des accidents communs du ble
    (CIMMYT, 1977) Christensen, C.M.; Dubin, H.J.; Fuentes, J.M.; Prescott, J.M.; Saari, E.E.
    L'objectif vise par ce fascicule est de faciliter l'identification des maladies, des ravageurs et des accidents du ble par les chercheurs, les vulgarisateurs et les producteurs de ble. Aucune mesure specifique de lutte n'est suggeree parce que ces moyens sont susceptibles d'etre differents d'un pays a l'autre. Les phytopathologistes et les entomologistes qui sont sur place devront Gtre consultes pour I 'identification des maladies et des ravageurs, ainsi que pour les mesures specifiques de lutte a utiliser.

    A systematic review of rye (Secale cereale L.) as a source of resistance to pathogens and pests in wheat (Triticum aestivum L.)
    (BioMed Central, 2017) Crespo Herrera, L.A.; Garkava-Gustavsson, L.; Ahman, I.
    Wheat is globally one of the most important crops. With the current human population growth rate, there is an increasing need to raise wheat productivity by means of plant breeding, along with development of more efficient and sustainable agricultural systems. Damage by pathogens and pests, in combination with adverse climate effects, need to be counteracted by incorporating new germplasm that makes wheat more resistant/tolerant to such stress factors. Rye has been used as a source for improved resistance to pathogens and pests in wheat during more than 50 years. With new devastating stem and yellow rust pathotypes invading wheat at large acreage globally, along with new biotypes of pest insects, there is renewed interest in using rye as a source of resistance. Currently the proportion of wheat cultivars with rye chromatin varies between countries, with examples of up to 34%. There is mainly one rye source, Petkus, that has been widely exploited and that has contributed considerably to raise yields and increase disease resistance in wheat. Successively, the multiple disease resistances conferred by this source has been overcome by new pathotypes of leaf rust, yellow rust, stem rust and powdery mildew. However, there are several other rye sources reported to make wheat more resistant to various biotic constraints when their rye chromatin has been transferred to wheat. There is also development of knowledge on how to produce new rye translocation, substitution and addition lines. Here we compile information that may facilitate decision making for wheat breeders aiming to transfer resistance to biotic constraints from rye to elite wheat germplasm.
