OCCURENCE OF FUSARIUM HEAD BLIGHT OF WHEAT IN SLOVAKIA UNDER THE NATURAL INFECTION
Occurrence of Fusarium head blight (FHB) was documented during two consecutive years in June 2011-2012 under the natural conditions in winter wheat (Triticum aestivum L.). Observations were conducted at six different localities in four climatic regions in Slovakia. Incidence and severity of FHB were evaluated at the end of flowering stage in three replications. Each replication contained 100 spikes. These data served as a basis for FHB index calculations. Obtained FHB index values indicated that the environmental conditions of the year 2011 were more favourable to the development of FHB infection. Higher FHB index values were reached at localities with precipitation higher than 100% of long-term average. Although significantly higher incidence of heads with FHB symptoms was recorded in climatic region 02 – quite warm, dry, hilly, correlation between the climatic regions was not confirmed. Except of the climatic conditions, the FHB development can be influenced by nitrogen application. The highest levels of FHB index was in coincidence with the highest and the lowest nitrogen rates applied. In all other cases, the effect of the mineral nutrition on head blight attack was unclear. Analyses of nitrogen forms applied revealed that nitrogen forms had no impact on FHB index value
Distribution, host plants and natural enemies of sugar beet root aphid (Pemphigus fuscicornis) In Slovakia
During 2003-2004, field surveys were realized to observe the distribution of sugar beet aphid, Pemphigus fuscicornis (K o c h) (Sternorrhyncha Pemphigidae) in southwestern Slovakia. The research was carried out at 60 different localities with altitudes 112-220 m a. s. l. Sugar beet root aphid was recorded at 30 localities. The aphid was recorded in Slovakia for the first time, but its occurrence was predicted and symptoms and harmfulness overlooked by now. The presence of P. fuscicornis was investigated on roots of various plants from Chenopodiaceae. The most important host plants were various species of lambsquarters (above all Chenopodium album). Furthermore sugar beet (Beta vulgaris provar. altissima), red beet (B. vulgaris provar. conditiva) and oraches (Atriplex spp) act as host plants. Infestation of sugar beet by P. fuscicornis never exceeded 5% at single locality in Slovakia. Dry and warm weather create presumptions for strong harmfulness. In Slovakia, Chenopodium album is a very important indicator of sugar beet aphid presence allowing evaluation of control requirements. During the study, the larvae of Thaumatomyia glabra (Diptera: Chloropidae) were detected as important natural enemies of sugar beet aphid. The species occurred at each location evaluated
Aceria artemisiifoliae Vidović & Petanović (Acari: Eriophyoidea) on common ragweed – the second record in the world
Common ragweed – Ambrosia artemisiifolia L. (Asteraceae) is an invasive plant species in Europe native
to North America. Most of the records of known eriophyid mites on different ragweed species are from their native
range. Our field experiments in Slovakia, 2016–2023, aimed to identify specific species feeding on common ragweed.
We searched for symptomatic plants and collected growing tips, which were then preserved in 70% ethanol for further
study. A recently described species of eriophyid mite, Aceria artemisiifoliae Vidović & Petanović (Acari: Eriophyoidea),
was found in western and eastern Slovakia. This is the first record of the species in Slovakia and the second record in
the world. It remains unclear whether this species is invasive like Ambrosia, and whether it could be used as a potential
biological control agent
Organic Farming e-book
A agricultura biológica está-se a tornar cada vez mais importante como um caminho preferencial para a produção de produtos agrícolas, face à crescente procura do mercado mundial. A relevância da agricultura biológica é ainda maior, devido à necessidade e procura de produtos agrícolas de origem biológica, que são isentos de produtos químicos, saudáveis e amigos do ambiente. Atualmente, a agricultura biológica resulta em produtos de valor acrescentado, mas estes sistemas de produção exigem abordagens especializadas. Verifica-se uma lacuna de conhecimento especializado para enfrentar os desafios e exigências da
agricultura biológica.
Além disso, um número crescente de pessoas com níveis elevados de educação está a mudar a sua atividade para a agricultura sem qualquer tipo de formação nesta área técnica, principalmente em países com dificuldades económicas, como Portugal.
Há, portanto, necessidade de desenvolver a capacidade de pessoas com algum tipo de qualificação prévio, a fim de melhorar suas competências agrícolas e facilitar a sua capacidade de desempenho e inovação, para que possam contribuir para a Estratégia Europeia (CE) de Desenvolvimento Rural.
Este e-book foi concebido para melhorar as competências desses agricultores. O seu objectivo geral é dotar os novos agricultores com conhecimentos e capacidades necessários para o desenvolvimento da cadeia de valor dos produtos da agricultura biológica.
Os objectivos específicos são:
i) Fornecer conhecimento básico em vários aspectos da agricultura biológica e áreas afins, tais como a gestão de recursos naturais (solo, água, plantas, ambiente) e
desenvolvimento rural (conservação, agricultura biológica e familiar,
multifuncionalidade).
ii) Facilitar a troca efetiva de conhecimento e experiências em agricultura biológica, desenvolvimento rural e ambiente. iii) Oferecer suporte técnico e conhecimento em agricultura biológica num contexto de
mobilidade e em ambiente de trabalho.
Este e-livro, produzido em sete idiomas diferentes (Português, Inglês, Espanhol, Italiano, Eslovaco, Turco e Húngaro) também contribui para preservar línguas e culturas Europeias e, assim, melhorar a comunicação entre os diferentes intervenientes e grupos-alvo.
O e-book inclui os princípios e técnicas da agricultura biológica, com base no triângulo planta-solo-ambiente e nas relações entre a produção animal e o ambiente. A preparação de alimentos e rotulagem, marketing e conversão à agricultura biológica são também abordados. Os princípios e as técnicas apresentadas são explicados com base em regras e diretrizes (normas), baseados numa abordagem logística que garante o equilíbrio e integridade do sistema. O e-book apresenta também os regulamentos e normas nacionais e Europeias que são obrigatórias para os agricultores biológicos.info:eu-repo/semantics/publishedVersio

Krajinné plánování a uplatňování krajinného plánu v ČR
This work is concerned with landscape planning and application in the landscape plan in Czech Republick. It compares the application of the landscape plan in other countries, such as Germany and Slovakia. Then describe Czech legislation and defines the problem of why landscape planning in our country does not work as good as spatial planning. The teoretical basis is then supplemented by design landscape plan for the city of Brno, using the program ArcGis, which is only a brief proposal
NATURAL ENEMIES OF DIURAPHIS NOXIA (STERNORRHYNCHA: APHIDIDAE) IN SLOVAKIA
A study from 2002 documented the occurrence of natural enemies (parasitoid wasps, predatory fl ies, entomopathogenic fungi) associated with colonies of the Russian wheat aphid, Diuraphis noxia (Kurdjumov, 1913) (Sternorrhyncha: Aphididae), in the spring barley fi elds in Slovakia. Parasitization by wasps was low (<5.5%) with Diaeretiella rapae (McIntosh, 1855) the dominant hymenopterous parasitoid (91% of emerging wasps). The remaining parasitoid guild comprised of Aphidius ervi Haliday, 1834 Aphidius rhopalosiphi DeStefani, 1902, Aphidius picipes (Nees, 1811), Ephedrus plagiator (Nees, 1811), Praon volucre (Haliday, 1833) (Hymenoptera: Aphidiidae) and two hyperparasites Asaphes suspensus (Nees, 1834) (Hymenoptera: Pteromalidae) and Lygocerus spp. (Hymenoptera: Ceraphronidae). Predaceous midges (Diptera: Cecidomyiidae) were consistently found with densities ranging from 0.1 to 2.5 larvae per aphid colony. The most abundant predaceous midge was Aphidoletes aphidimyza (Rondani, 1847), while Lestodiplosis sp. was recorded infrequently. Four syrphids, Episyrphus balteatus (De Geer, 1776), Melanostoma mellinum (L., 1758), Sphaerophoria rueppellii (Wiedemann, 1830), Sphaerophoria scripta (L., 1758) (Diptera: Syrphidae) and one pathogenic fungus, Pandora neoaphidis (Remaudière et Hennebert) Humber, were recorded

Parazitácia vošiek bola nízka (<5.5%). Dominantným blanokrídlym parazitoidom bol druh Diaeretiella rapae (McIntosh, 1855) (tvoril 91% zo všetkých
parazitoidov). K ostatným parazitoidom patrili, Aphidius ervi Haliday, 1834 Aphidius rhopalosiphi DeStefani, 1902, Aphidius picipes (Nees, 1811), Ephedrus plagiator (Nees, 1811), Praon volucre (Haliday, 1833) (Hymenoptera: Aphidiidae) a dva hyperparazitoidy Asaphes suspensus (Nees, 1834) (Hymenoptera: Pteromalidae) a Lygocerus spp. (Hymenoptera: Ceraphronidae). Populačná hustota dravých byľomorov (Diptera: Cecidomyiidae) bola konzistentná a
pohybovala sa od 0,1 do 2,5 larvy na jednu kolóniu vošiek. Najhojnejším druhom dravého byľomora bol Aphidoletes
aphidimyza (Rondani, 1847), zatiaľ čo Lestodiplosis sp. bol zaznamenaný iba zriedkavo. Spomedzi ďalších prirodzených
nepriateľov boli zaznamenané štyri druhy pestríc, Episyrphus balteatus (De Geer, 1776), Melanostoma mellinum (L.,
1758), Sphaerophoria rueppellii (Wiedemann, 1830), Sphaerophoria scripta (L., 1758) (Diptera: Syrphidae) a jedna entomopatogénna huba, Pandora neoaphidis (Remaudière et Hennebert) Humber
