ABSTRACT - Fungi of the genus Pyricularia have a wide range of host plants and are capable of infecting more than 50 species of grasses, causing the blast disease, with damage to the ears. Species of the forage signal grass (Urochloa spp.) can be hosts of this genus of fungus and can be an important source of inoculum of the pathogen for other agri...
Leaf rust, caused by Puccinia triticina (Pt), is a major disease of wheat and a significant problem for wheat production in Brazil. The Brazilian variety Toropi, released in 1965, has maintained high levels of field, adult plant resistance (APR) to leaf rust across global locations, while microscopic studies have indicated prehaustorial resistance ...
The study aimed to characterise the flag-leaf metabolomes of two spring wheat cultivars (Triticum aestivum L. cv. PF 080719 [PF] and cv. Fundacep Horizonte [FH]) following challenge with Ptr to gain insights into TS disease development.
Os eventos de calor extremo tem sido reportados com mais frequência nos últimos anos. Entretanto, poucos estudos abordamos efeitos destes eventos sobre os fluxos turbulentos na camada limite atmosférica. Este estudo tem como objetivo investigar ocomportamento anômalo nos fluxos de calor sensível e latente e sua relação com eventos de calor extremo ...
[ES] Como consecuencia del gran incremento previsto de la población mundial, la demanda de alimentos no hará más que aumentar. Si se pretende garantizar la adecuada ingesta de la población se deberá recurrir a nuevas herramientas que permitan el buen manejo de los recursos finitos con que contamos, así como el mantenimiento del medio ambiente en un...
[ES] La Fusariosis de la Espiga (FHB) representa una amenaza significativa para la producción global de trigo, causando pérdidas de rendimiento, contaminación por micotoxinas y poniendo en peligro la seguridad alimentaria. El desarrollo de variedades de trigo resistentes a FHB mediante métodos convencionales de mejora es un desafío debido a la comp...
In this study, we gathered data on Fusarium head blight (FHB) severity, deoxynivalenol (DON), and wheat yields from 19 cooperative fungicide trials conducted in Southern Brazil over five growing seasons (2017?2021). We tested three premixes of Quinone Outside Inhibitors (QoIs) + demethylation inhibitors (DMIs) (PYRAclostrobin + METConazole, TEBUcon...
