Teratosphaeria nubilosa severely affects young plantations of Eucalyptus globulus and Eucalyptus maidenii in Uruguay. This work analyzes the effect of the damage caused by T. nubilosa on tree growth and survival of E. globulus and E. maidenii, based on data from a trial naturally infected by this pathogen. The effect of defoliation and proportion of adult foliage on tree growth and mortality was evaluated at 50 months of age. Defoliation in E. globulus was higher than in E. maidenii, reaching average values of 52.5 and 28.8 %, respectively, at 21 months of age. By contrast, E. globulus showed higher precocity of vegetative phase change than E. maidenii. Although the damage threshold for diameter growth was 40 % on E. globulus and 20 % on E. maidenii, the detrimental effect on growth was similar in both species, where the most defoliated trees suffered a reduction in diameter of 49.4 and 47.5 %, respectively, at 50 months of age. Mortality increased significantly when defoliation exceeded 30 % in E. globulus and 40 % in E. maidenii. The results showed that E. maidenii has lower defoliation, higher growth and lower mortality than E. globulus after epidemics of T. nubilosa. However, the lower defoliation and higher proportion of juvenile foliage showed by E. maidenii represent a greater source of inoculum, suggesting that a large-scale replacement of E. globulus by E. maidenii in areas where T. nubilosa is a problem could be risky from an epidemiological point of view. |

ABSTRACT.
Excessive vine growth not only negatively impacts fruit composition but also fosters bunch rot incidence. The goal of our study was to improve Vitis vinifera (Tannat) grape and wine composition and decrease bunch rot incidence by achieving adequate vine vegetative growth in a humid climate. Our approach was to use under-trellis cover crops (UTCC) to limit vine water availability and reduce excessive vine growth. We tested UTCC consisting of full cover of the vineyard soil with red fescue (Festuca rubra) versus conventional alleyway red fescue with 1.0 m wide weed-free strips under the trellis (H). As excessive competition with grapevines remains the main reason for UTCC rejection, this strategy was tested in combination with two irrigation schedules?irrigation to avoid water restriction at bloom (Ir) vs. no early irrigation?and two nitrogen inputs (0 vs. 100 kg N ha−1) over three growing seasons in southern Uruguay. Treatments were arranged in a split-split-plot randomized block design with cover crop schemes as main plots, water availability as subplots and nitrogen inputs as sub-subplots. Shoot growth rate, mid-day stem water potential (Ψstem), berry size and berry composition were monitored over the season, as well as final yield, cluster and pruning weights. UTCC significantly reduced vine vegetative growth, while no significant differences were detected between H and UTCC when irrigation took place early in the season. Even nitrogen input showed positive effects on grapevine vegetative growth in some cases, water availability at bloom was the key driver of vegetative growth. UTCC treatments increased grape soluble solids (TSS) in the last two out of three seasons and consistently increased anthocyanin concentration in grapes. Independent of vegetative growth, strong differences in bunch rot incidence were detected between H and UTCC treatments. Seasonal variations in water status and/or free amino nitrogen content of grapes may have a relevant impact on disease susceptibility at harvest.
