Japanese knotweed, Fallopia japonica is one of the most troublesome invasive alien plant in Europe and North America. In 2012 we started monitoring for possible indigenous natural enemies of Japanese knotweed in Slovenia. In Zgornji Log, near Litija (46°4′38.09″N, 14°49′31.65″E; 245 m) on the river ...

Symptoms of downy mildew were observed in buckwheat trials at the Washington State University (WSU) Mount Vernon Northwestern Washington Research and Extension Center (NWREC) in Skagit Co. in 2014, 2015 and 2016 and in growers' buckwheat crops in Jefferson and Skagit counties in 2016 at incidences...

Biological invasions are an important problem of human-induced changes at a global scale. Invasive plants can modify soil nutrient pools and element cycling, creating feedbacks that potentially stabilize current or accelerate further invasion, and prevent re-establishment of native species. The aim ...

A greater theoretical awareness is growing in recent years more and more researchers lave turned to ethnobiology. In this essay the author provides a background to ethnobiology as a scientific field, which traditionally investigates local knowledge, use, beliefs, folk taxonomies and names of...

The impacts of the invasive plant Japanese Knotweed (Fallopia japonica) on native plant and invertebrate communities in its introduced range have been relatively well studied, and studies have revealed predominantly negative impacts. However, little research has focused on the impact of knotweed on ...

Nitrogen (N) limits plant growth in many ecosystems and denitrification is a major source of N loss from soils. Fallopia spp. is an invasive plant species complex adapted to low-fertility soils, which is responsible for biological denitrification inhibition (BDI) through the production of...

Fallopia japonica (Japanese knotweed) native to Japan is an aggressively invasive plant in the world, but also it contains a biological active natural compounds. Most important compounds of anti-aging by which can activate responsible gene sirtuin in nature is stilbenes trans-resveratrol (...

Anthracnose lesions on curly dock (Rumex crispus) were found in a plant nursery in Changchun, Jilin, China, in July 2013 and 2014. Symptoms on diseased leaves initially included small, scattered, red, circular spots 1-2 mm in diameter. As the disease progressed, circular spots developed and...

The paper presents the results of floristic and vegetation analyses of the landfill Supíkovice. Ruderal, segetal and meadow vegetation units were recorded in June 2015. The most interesting findings were threatened weed species growing in decontamination patches on loamy and nutrient-poor soils in...

Knotweed is an invasive plant that creates high compact growth when uncontrolled that can suppress the growth of native plants and thus reduce biological diversity. These invasive plants contain many antioxidants that require identification and quantification. In this work, aqueous 2% acetic acid,...
