Teratosphaeria nubilosa severely affects young plantations of Eucalyptus globulus and E. maidenii in Uruguay. This work analyzes the
effect of this pathogen on the growth and survival of both species, based on data from a naturally infected field trial. The degree of defoliation was quantified at 21 months old, and its effects on diameter and mortality were evaluated at 62 months old. Defoliation in E. globulus was higher than in E. maidenii, with an average of 52.5 and 28.8%, respectively. Four years after the epidemic, defoliation classes of 40% or higher had significant growth losses on E. globulus, while losses in E. maidenii were significant when defoliation was 30% or higher. An average loss in DAP of 27.5 % in E. globulus and 12.5 % in E. maidenii was observed. The most affected trees, with 70-80% of defoliation in E. globulus and 60% in E. maidenii, had similar growth loss in both species, suffering a reduction in DAP of 43.9% and 42.5%, respectively. By contrast, the average mortality that occurred between 21 and 62 months old was significantly higher in E. globulus (16.7%) than in E. maidenii (3.3%). Mortality in the higher defoliation classes reached 44.7% on E. globulus and 47.1% on E. maidenii. Although E. globulus showed greater susceptibility to the disease and higher productivity losses, the significant defoliation and growth losses registered in E. maidenii suggest that this species is not as suitable as previously thought to replace E. globulus on sites with high risk of T. nubilosa.

ABSTRACT.
The chemical control of Fusarium Head Blight (FHB) using fungicide has remained an unresolved challenge worldwide. Experiments using fungicides to control the disease have shown large difference of effi ciency due to multiple factors (fungicides, moment and method of application, nozzle types, and weather conditions at the time of application, etc.) responsible for disease development. Besides adequate disease control, the fungicides are also expected to act on toxin production. Results have shown that highly susceptible cultivars cannot be fully protected under severe epidemic conditions. For this reason these cultivars need to be withdrawn from commercial production and chemical control be applied as
preventive measure based on the FHB developmental models and weather forecasts. Presently one of the most effi cient fungicides to control FHB in the Southern Cone region is Metconazole followed by the Tebuconazole. Other fungicides (Prochloraz, Thiabendazole, Carbendazim, etc.) used earlier are less effi cient compared to the triazoles mentioned earlier. Under experimental conditions, nozzle types like Twinjet 60 or Turbo TeeJet Duo have shown an increase the disease control effi cacy. The earliest time to spray is after complete heading, beginning of fl owering or mid fl owering depending on the year and weather conditions.
