VELASQUEZ-VALLE, Rodolfo; MACIAS-VALDEZ, Luis Martín  and  REVELES-HERNANDEZ, Manuel. Common pathogens of garlic seed in Aguascalientes and Zacatecas, Mexico. Rev. Mex. Cienc. Agríc [online]. 2017, vol.8, n.8, pp.1881-1885. ISSN 2007-0934.

Garlic is the most important horticultural crop during the winter in the states of Aguascalientes and Zacatecas, Mexico. The presence of abiotic and biotic damage in the garlic seed of this region is unknown, consequently, the objective of this work was to determine the incidence of pathogens and abiotic damage in garlic bulbs used as seeds during the year 2015. Bulbs of garlic of different varieties, the teeth of each bulb were separated and counted the number of healthy and damaged teeth for their observation. The bulbs of three varieties of garlic (Chilean, Hermosillo and Silver) did not show any type of damage. The most common pathogen was the fungus Ulocladium spp. although others such as Alternaria spp., Fusarium spp., Curvularia spp, Rhizoctonia spp., Penicillium spp., and Verticillium spp. The Rhyzoglyphus mite was detected in only five of the collected varieties. Chemical damage was detected affecting 52% of the varieties collected. Weight losses caused by abiotic or biotic damage were more severe in the Durango, Calerense and Spanish varieties.

Keywords : chemical damage; fungi; garlic varieties; mites.
