In this part of Mexico, E. crassipes flourishes from
September to October. According to Luu and Getsinger
(1988), nonflowering plants produce over twice the number
of ramets and nearly double of biomass, compared to
flowering plants. Therefore, when biocontrol was applied,
E. crassipes was in the optimal point for control, since a
decrease in its ramet production and biomass were possible
during its flourishing time. Besides, most of the E. crassipes
leaves in the reservoir, showed symptoms of Cercospora
piaropi infection before plants pathogens were applied.
