ABSTRACT.
Species of the Botryosphaeriaceae are important pathogens causing cankers and die-back on many woody plants. In Uruguay, Neofusicoccum eucalyptorum, N. ribis and B. dothidea have previously been associated with stem cankers on plantation-grown Eucalyptus globulus. However, very little is known regarding the occurrence and species diversity of Botryosphaeriaceae in native Myrtaceae forests or what their relationship is to those species infecting Eucalyptus in plantations. The objectives of this study were to identify the Botryosphaeriaceae species present as endophytes or associated with cankers in both introduced and native tree hosts in Uruguay, and to test the pathogenicity of selected isolates obtained from native trees on Eucalyptus. Symptomatic and asymptomatic material was collected countrywide from Eucalyptus plantations and native Myrtaceae trees. Single spore cultures were identified based on conidial morphology and comparisons of DNA sequences of the ITS and EF1-α regions. Six Botryosphaeriaceae species were identified. Botryosphaeria dothidea, N. eucalyptorum and specimens residing in the N. parvum-N. ribis complex were isolated from both introduced Eucalyptus and native Myrtaceae trees, whereas Lasiodiplodia pseudotheobromae was found only on Myrcianthes pungens. Diplodia pseudoseriata sp. nov. and Spencermartinsia uruguayensis sp. nov. are novel species found only on native myrtaceous hosts. Pathogenicity tests showed that isolates obtained from native trees and identified as L. pseudotheobromae, N. eucalyptorum and the N. parvum-N.ribis complex are pathogenic to E. grandis. Interestingly, Lasiodiplodia pseudotheobromae has not previously been found on Eucalyptus in Uruguay and represents a potential threat to this host.

Nutrition during gestation has an important role at time of parturition for both mother and offspring. The effect of different nutritional management during the last month of pregnancy on body condition (BCS), body weight (BW) and mother-lamb behaviour at parturition was evaluated. One hundred and forty multiparous Corriedale ewes gestating a single lamb were offered native pasture (7% crude protein (CP)) during the first four months of gestation and were assigned to two differential nutritional management during the last month of pregnancy: (1) ewes grazing oat pasture (14% CP) (GO, n=71); (2) ewes fed native pasture (GNP, n=69), regarding BW and BCS at the beginning
of the treatment (49.1±0.7 vs 49.7±0.7 kg and 3.74±0.05 vs 3.77±0.05 GO and GNP respectively). At parturition BW and BCS were registered, as well as duration of labour, delivery assistance and Maternal Behaviour Score (MBS,range 1-5). In lambs, birth weight, Apgar test for newborns (score 0-10), and time elapsed to stand and suck was recorded. Data were analysed using PROC MIXED and GENMOD of SAS, (mean ± SEM; P?0.05). At parturition GO ewes had higher BW (56.7±0.8 vs 52.7±0.7 kg P?0.0001) and BCS (3.7±0.04 vs 3.4±0.06 P=0.0007) than GNP. Duration of labour was longer (32.5±4.7 vs 24.03 min, p?0.001) and percentage of delivery assistance was significant
greater (22.5 vs 4.3%) in GO group. Lambs from GO mothers were heavier (4.77±0.07 vs 4.28±0.09 kg, P=0.0037),and took longer to stand (36.4±4.2 vs 28.5±3.9 min, p?0.001) and suck (56.4±5.2 vs 51.5±4.9 min, P=0.0011) than GNP lambs. There was no effect on MBS or Apgar test. The increment in BW and BCS of GO animals resulted in heavier lambs, that led to longer time of labor and less vigor compared with lambs of GNP ewes. Higher percentage of birth assistance in GO ewes suggests that the benefit of a greater weight at birth can be exploited only if control of parturition is performed. However, grazing oat pasture should be an alternative to be used with twin bearing ewes
since lambs are usually lighter and have less vigor than single ones. MenosNutrition during gestation has an important role at time of parturition for both mother and offspring.
