ABSTRACT.- Pecan scab caused by Venturia effusa is the main crop disease affecting leaves and fruits, resulting in defoliation and yield and fruit quality losses. Recently, pecan groves expanded into Uruguay, Brazil and Argentina, where the temperate-humid climate is conducive for scab development. Chemical control is difficult given the height of adult trees which exceeds 20 m. Therefore, the strategy consists on selecting tolerant cultivars accompanied by cultural management aimed at providing a good ventilation and light interception. The objective of this work was to assess the susceptibility of pecan cultivars to Venturia effusa in the Uruguayan agroclimatic conditions. Disease severity index (DSI) in fruits and leaves were determined in 18 cultivars throughout four consecutive seasons. Most of the cultivars evaluated were classified as resistant with fruit disease severity index (DSIF) below 2.0, being Elliott and Sumner the most resistant ones (DSIF < 1.5) while Mahan was susceptible (DSIF > 3.0) and Apache and Wichita were very susceptible (DSIF > 4.5). © 2022 Informa UK Limited, trading as Taylor & Francis Group |

ABSTRACT: Objective: Our objectives were to compare the effects of feeding eucalyptus bark or eucalyptus wood chips, both by-products from the pulp industry, on voluntary feed intake, animal performance, and physiological variables of heifers finished on high-concentrate diets. Materials and Methods: Forty-eight British-breed heifers (Angus, Hereford, and their crosses) that were 22 to 24 mo of age and had an initial BW of 355 ± 8 kg were used. Four heifers were allocated to each of the 12 pens (experimental units). The experiment was a randomized complete block design with 2 treatments and 6 replications each. The 2 different fiber sources (wood chips or bark) were included in the fattening diet in the same proportion (8.9% DM basis). The rest of the ingredients in the diet were the same. The final diet was offered 3 times per day, and heifers were fed for 84 d. Results and Discussion: Fiber source (wood chips vs. bark) did not affect ADG or G:F (P > 0.10). However, DMI (P < 0.01), DP (P = 0.04), and hot carcass weight (P = 0.06) were greater in heifers fed with bark compared with those fed with wood chips. Heifers from the bark treatment spent less time (P = 0.02) chewing than heifers from the wood chips treatment. Implications and Applications: In conclusion, bark could be used as a source of fiber for finishing cattle in high-concentrate diets at the same levels as wood chips. This finding is relevant for the feedlot industry because eucalyptus bark has no industrial uses and would represent a cheaper fiber source than wood chips.
