Many Teratosphaeria species are associated with leaf diseases on Eucalyptus spp. (Myrtaceae). However, only a few of these are major pathogens that cause serious losses, particularly to plantation forestry globally. Several species in the Teratosphaeraceae and Mycosphaereaceae species are known to occur in Uruguay where they cause leaf and shoot diseases on Eucalyptus plantations, but most are of minor importance. However, two species have had a serious negative impact on the performance of certain Eucalyptus species. Since its first detection in 2007, Teratosphaeria nubilosa has eliminated Eucalyptus globulus from the available species for pulpwood production. Species substitution has been the main management tool for this pathogen resulting in negative consequences such as limited access to external markets. More recently, in 2011, Teratosphaeria pseudoeucalypti was reported causing leaf blight that has resulted in severe defoliation and death of established Eucalyptus camaldulensis, E. tereticornis, and their hybrids. This pathogen was first described in Australia in 2010 and simultaneously reported in Argentina, Brazil and Uruguay four years later. This disease is a serious threat to Uruguayan plantations and has already imparted a significant social and economic impact in the country where it has damaged urban parks and plantations used for shelter and shade for livestock production. These two examples of serious diseases caused by Teratosphaeria spp. have highlighted that accidentally introduced non-native pathogens can have in a country. They have also raised concerns that such pathogens could threaten the many native Myrtaceae found natural forest ecosystems in Uruguay.

This research sought to minimize inorganic arsenic levels in polished rice grain by using different irrigation and phosphorous fertilization practices while also maintaining crop yield and water productivity. Two experiments were conducted during seasons 2018?2019 and 2019?2020 using a split-plot design with three blocks, five irrigation treatments (main-plots) and two phosphorous levels (sub-plots). Irrigation treatments consisted of a traditional continuous flood (CF) control and four alternatives irrigation techniques with one or two drying
events during the irrigation cycle. The phosphorous fertilization levels investigated were an unfertilized control (0 kg P2O5 ha− 1 ) and the recommended fertilization level of 50 kg P2O5 ha− 1 . Soil pH and redox potentials were measured in each treatment. Strategically-timed, low severity drying events were effective at achieving aerobic soil conditions, resulting in Eh values over 50 mV. The alternative irrigation treatment with two drying events, implemented at panicle initiation and full flowering, was the most effective in reducing inorganic arsenic in grain without affecting grain yield or the amount of irrigation water applied. This irrigation technique could be considered as an alternative management to the traditional continuous flooded to reach minimal inorganic arsenic accumulation in grain in order to attend special quality standards or specific market requirements. Accumulated inorganic arsenic in grain was below international maximum levels in all analyzed samples, with an average value of 0.084 mg kg− 1
