Active Biodegradable Starch/PBAT-poly(butylene adipate-co-terephthalate) Film with Essential Oil Incorporation.

Plastic pollution and the reduction in synthetic food additives are demands that emerge from consumers, leading to the development of biodegradable plastic materials. The use of essential oils-EOs-has been researched because it is a natural product with antioxidant properties. Due to its nature, EO is composed of volatile compounds that can be lost during extrusion.

First report of causing leaf spots on (Camb.) Berg in Brazil.

is a native tree that produces fruit that can be consumed fresh or used by industry (Donadio et al., 2002). In February 2022, in the experimental area of the Universidade Tecnológica Federal do Paraná - Brazil, disease was observed in 22 trees, with 50% to 80% severity in crown leaves.

First report of Myrtle Rust caused by on (O. Berg) D. Legrand in Paraná state, Brazil.

is a tree fruit native to Brazil, unknown to a large part of the population, with fruit consumed only locally. In October 2022, at the experimental area at Universidade Tecnológica Federal do Paraná (UTFPR) in the Dois Vizinhos city, Paraná State, Brazil, symptoms of the disease were observed on mature leaves and fruits of 17 trees. Fungal fructifications were observed in the form of bright yellow uredinia containing a large mass of urediniospores on the surface and on the leaves and fruits that resembled the structures typical of a Myrtaceae rust pathogen.

First Report of Myrtle Rust Caused by in (Camb.) Berg in Brazil.

is a Brazilian fruit tree that has ecological importance and the potential to be explored by the food and medical industries (Lima et al., 2011). In February 2019, in the experimental orchard at the Universidade Tecnológica Federal do Paraná, Dois Vizinhos city, Paraná State - Brazil, disease symptoms were observed on leaves, stems, and fruits of 22 trees.

First Report of Myrtle Rust Caused by on in Brazil.

The fruit can be consumed in natural or processed form (jellies and juices) (Infante et al., 2016). In 2019, in the UTFPR, Dois Vizinhos city, Paraná State - Brazil, yellow uredinias epiphyllous were observed on the tissue surface (leaves, stems, flowers, and fruit) of twenty-one trees of , which resembled structures typical of Myrtaceae rust.

First Report of Causing Leaf Spot of in Brazil.

(DC) is a native fruit species of forest formations in the Atlantic Complex and in the forests and savannas of the Paraná State, Brazil (Donadio, 2002). In February 2021, in the experimental area at the Universidade Tecnológica Federal do Paraná, in the Dois Vizinhos city, Paraná State, Brazil, a foliar disease was observed on twenty-two12 years old trees, with 20 to 80% of the leaves per tree affected. Symptoms were small, irregularly to circular shaped, reddish-brown lesions with yellow halos.

Management of pruning and evaluation in blackberry cultivars in relation to productive characteristics and bioactive compounds.

The goal of this work was to evaluate blackberry cultivars in terms of productivity and bioactive compounds. Two experiments were conducted: in the first experiment four cultivars were evaluated (Cherokee, Guarani, BRS-Tupy and Xavante). In the second experiment, the effects of pruning management in the BRS-Tupy cultivar were evaluated with the following treatments: drastic winter pruning (zero primocane), and maintenance of two, three or four primocanes in the winter pruning.
