ABSTRACT.- Since 2015, a high mortality rate of strawberry plants has been observed in the north of Uruguay related to crown and root diseases caused by a pathogens complex. In 2016, associated with the death of plants, Cylindrocarpon spp. was isolated with a frequency of 42.4 %, ranking third, preceded by Neopestalotiopsis sp. and Fusarium spp. Aiming to increase the knowledge of the pathogens that integrate the complex, three isolates of Cylindrocarpon spp. were characterized by molecular, morphological and pathogenicity analyses in strawberry plants. Dactylonectria novozelandica was identified as causal agent of crown and root necrosis of strawberry in Salto, Uruguay. .-.-.-.-.-.-.-.-.-.-..-RESUMEN.- Desde 2015, se observó una alta mortandad de plantas de frutilla en el norte de Uruguay relacionada con enfermedades de corona y raíz causadas por un complejo de patógenos.

Timely grazing decision-making requires routine information on the herbage mass (HM) and pasture growth rate (GR). The aim of this study was to compare the correspondence, cost, and reliability of two indirect methods -the comparative yield method (COMPYLD) and the pasture-meter (CDAX)- to estimate HM and weekly GR of a 42 ha grazing area. Weekly assessments from Apr 2017 to Oct 2018 were made with both methods to estimate HM and GR of 13 individual paddocks. In addition, estimated GR were compared to aerial net primary productivity (ANPP) estimated using remote sensing (SAT). Estimated HM was 22% lower for COMPYLD than CDAX (HMCOMPYLD=33+0.78*HMCDAX, R2=0.61, CV=17%, RMSE=291 kgDM/ha). The correspondence between methods of estimated weekly GR of individual paddocks was weak (GRCDAX=0.18*GRCOMPYLD+19.1, R2=0.05, CV=73%, RMSE=21.8 kgDM/ha/d). However, when integrated in three-week moving-averages, over the complete grazing area, COMPYLD and CDAX yielded similar GR up to 35 kg DM/ha/d. Accumulating GR of the grazing area over one year resulted similar to annual SAT-estimated ANPP. These results imply that, on one hand, decisions based on nominal HM, such as target HM and grazing strip size, would need to be adjusted depending on the method, but on the other hand, decisions based in temporal trends or GR, such as size and timing of setaside areas for reserves, would be unaffected by method. Compared with COMPYLD, CDAX would be advantageous whenever high labour costs offset higher amortization, maintenance and fuel costs, provided there is an alternative in place to monitor during downtime periods. © 2023 Cambridge University Press.
