ABSTRACT.- This study evaluated the in vitro effects of common insecticides used for stink bug (Hemiptera: Pentatomidae) control in soybeans on Beauveria bassiana and Lecanicillium attenuatum. The effects of thiamethoxam + lambda-cyalothrin, imidacloprid + beta-cyfluthrin, thiamethoxam and trichlorfon were tested at field-recommended (FD), half and double FD doses for their impact on vegetative growth and conidial production. At FD only thiamethoxam did not significantly affect the mycelial growth of both strains 14 d after inoculation.

ABSTRACT.- Long-term interdisciplinary research rooted in Agricultural Long-Term Field Experiments (LTEs) is crucial for understanding the sustainability of agroecosystems. This is particularly relevant for designing agroecosystems that prevent further land and environment degradation and support farmers to achieve long--erm goals of sustainabilityby promoting internal ecological cycles, reducing the dependency on non-renewable and external inputs, and optimizing the use of water and energy. @2024 Agrociencia Uruguay.

ABSTRACT.- The retail sector has a significant impact on the meat supply chain, playing a key part not only in logistics but also in shaping production and consumption patterns. Latin America is an important region for livestock production and global trade in animal products, with Mexico emerging as a major player in the sector due to its remarkably resilient livestock industry. Previous studies suggest that the Latin American meat industry is not meeting consumer demand for products with specific attributes.

ABSTRACT.- Tomato leaf spot, caused by the ascomycete fungi Stemphylium spp., including S. lycopersici, S. solani and S. vesicarium, is a severe threat to tomato production worldwide. In Uruguay, the disease has become more prevalent in both field and greenhouse production systems in recent years, primarily due to the use of susceptible tomato varieties. This study focuses on the identification, morphological characteristics, genetic diversity and virulence of Stemphylium isolates responsible for leaf spot in Uruguay's major tomato-producing regions.

ABSTRACTS.- The efficacy of natamycin (Fruitgard Nat 20) and Proallium (an extract of allium including propyl thiosulfinate oxide (PTSO)) against sour rot and green mold in mandarins was evaluated under controlled and commercial conditions. The study involved artificial inoculation of Nova, Tango, Orri, Afourer, Murcott, and Nules Clementine mandarins with isolates of Penicillium digitatum resistant to imazalil and pyrimethanil and an isolate of Geotrichum citri-aurantii susceptible to propiconazole fungicides. © 2024 by the authors.

ABSTRACT.- Amaranth (Amaranthus spp.) resistant to glyphosate and diclosulam represent the most important weed complex in Uruguayan agricultural systems. The objective of this study was to evaluate the use of cover crops (CC) and herbicide strategies (HS) in the management of amaranth. The work was divided into two stages, the first conducted at the field, where the use of CC and pre/post-emergent HS was evaluated. Black oat and Rye were used as CC, and 15 HS (pre and/or post-emergent) were applied to manage amaranth in soybean crops.

ABSTRACT.- The thirtieth anniversary of the Sociedad Uruguaya de Fitopatología -SUFIT- celebrated in 2023, signalled a time of growing depth of the discipline and
marked a milestone in the process of outreach to other fields directly related with plant protection and plant health, like entomology and weed science. © 2024 Informa UK Limited, trading as Taylor & Francis Group

ABSTRACT.- Paspalum L. is a genus of the Poaceae family, with many species serving as well-adapted forage plants in subtropical climates and continuous grazing systems. However, Claviceps paspali, an ascomycete of the order Hypocreales, represents a major threat to Paspalum species. This fungus induces ergot disease, characterized by the replacement of infected flower seeds with sclerotia, which adversely affects seed production and animal health through mycotoxin production.
