Morphological description of Globodera rostochiensis and its relationship with the phenological cycle from potato (Solanum tuberosum)

Abstract

In this paper, the relationship between the nematode Globodera rostochiensis and Solanum tuberosum was studied. The nematode occurs at different stages of S. tuberosum development. It could be observed as small cysts under the microscope. This study was carried out in a potato crop at El Cebollero, a farm located at Ixtacamaxtitlan in Puebla state, Mexico. It will be described step by step how the G. rostochiensis was identified through the various stages of the potato, in which it attacks the potato, so that this influences to decrease to 58% or sometimes the loss is complete. Different chemicals are applied, each year, to control such as methyl bromide, Organophosphate and carbamate, however, the parasites have developed hight resistance to these, therefore a high economic impact on many farmers that grow the tubers.
