Opis:: The subject of the following study is the reaction of six varieties of soybeans (Glycine max L. Merr.): Abelina, Augusta, Merlin, Mavka, Aligaor, Lisabon, on an aqueous decoction of dried Artemisia absinthium L. used as wet seed treatment. The experiment was carried out in a greenhouse belonging to the Experimental Station for Variety Testing in Karzniczka. Two combinations of the extract were used: 24h soaking of seeds in the decoction followed by sowing and soaking in distilled water followed by sowing, but untreated seeds with simultaneous dosing of herbal extract. The control group were seeds not treated with preparations. After sixteen days of the test, the average number of plant growth was determined for each experimental combination. The morphological characteristics of the seedlings: length of shoots and roots as well as fresh and dry mass of shoots and roots were evaluated for ten randomly selected plants from each experimental combination. The results of the greenhouse experiment showed different reaction to the application of the decoction in the form of a seed treatment. Soil application of the extract led to the improvement of soybean growth. Seedlings of all varieties, the seeds of which were treated and sown, developed a longer and stronger root system at the expense of a slight reduction in the length and weight of the shoots. The 24h soaking of seeds in the decoction of Artemisia absinthium caused the deterioration of emergence and the visible inhibition of the growth and development of soybean seedlings. The inhibition of germination and emergence by the tested extract excludes the possibility of agricultural application. Further research is needed to identify the bioactive compounds contained in the used decoction and to assess the real effectiveness of the soil application of the extracts under field conditions.

Opis:: The purpose of the research conducted was to define the impact of the various aqueous extract concentrations, prepared from the dried (in concentrations 2%, 5% and 10%) and fresh (in concentrations 10%, 20% and 30%) tansy (Tanacetum vulgare L.) mass, on the feeding of pea leaf weevil (Sitona lineatus L.), and the mortality rate of black bean aphid (Aphis fabae Scop.). The studies showed that in order to limit the feeding of pea leaf weevils considerably, it is necessary to use at least 5% extract of the dried tansy mass or 20% extract of the fresh tansy mass. The impeding effect on the feeding of pea leaf weevils was correlated positively with the extract concentration. The insecticide effect of the aqueous extract of tansy on black bean aphid was revealed not earlier than after 12 hours with the use of at least 20% extract of the fresh tansy mass and 5% extract of the dried mass (only in relation to aphid larvae). Nevertheless, the extracts of lower concentration also demonstrated the insecticide effectiveness although delayed (36–60 hours after the application). As compared to other studies conducted according to the same methodology, it was demonstrated that the tansy aqueous extracts are characteristic for a high deterrent activity in relation to the pea leaf weevil beetles (higher than the extracts of absinthe and similar to the extracts of pepper mint and sage) and a quite high aphicidal activity (higher effectiveness than in the case of the aqueous extracts of lemon balm but lower than the extracts of tarragon and absinthe).

Opis:: The aim of this study was to determine the effect of water extracts prepared from fresh and dry matter of wild thyme (Thymus serpyllum L.) on feeding adults and larvae of Colorado potato beetle (Leptinotarsa decemlineata Say.). The experiment was conducted in the laboratory, in six replicates. Dry extracts were prepared at concentration of 2%, 5% and 10%, while the fresh plant at concentration of 10%, 20% and 30%. Feeding intensity assessment was conducted by dipping leaves of potato in respective solutions of the extracts and determining the mass of food consumed by adults and larvae, and changes of larvae body weight once daily. In addition, absolute deterrence index and palatability index were calculated. The results of the experiment showed that for an efficient limitation of the feeding adult Colorado potato beetles, an extract from dry matter of wild thyme with a concentration of at least 10% should be used. L4 larvae appear to be considerably more susceptible to the effect of T. serpyllum extract. In their case, an efficient limitation of the feeding, as well as body weight gain can be obtained using extracts from both dry and fresh matter, at concentrations of over 5% for dry matter and over 20% for fresh matter. With the increase of extract concentration, the value of the calculated palatability index decreases, and the deterrence index value increases.

Opis:: The Solidago canadensis (Canada goldenrod) species is an invasive plant in Europe and Asia. It grows mainly in anthropogenic environments, including those with a high content of heavy metals in soil. Goldenrod is also a honey plant, and its inflorescences and leaves are used in herbal medicine. The aim of the study was to determine the content of metals: Mg, Mn, Cu and Zn, in inflorescences and leaves of S. canadensis and in water extracts prepared from them. Material for the research was obtained in Poland. The content of the metals was determined by atomic absorption spectrometry. It was found that leaves of S. canadensis contained more Mg and Zn, but less Cu compared with inflorescences. The content of the metals in water extracts was proportional to their content in the raw material, except the content of Mn in leaves. Among the metals studied, the highest extraction of Cu and Mg was noted in infusions of leaves and inflorescences, while Zn achieved the highest extraction in infusions of inflorescences. Mn was extracted to the least extent both in leaves and inflorescence infusions. Infusions of goldenrod leaves provided similar amounts of Mg, Cu and Zn as tea infusions. Infusions of inflorescences provided more Cu and Zn than infusions of chamomile flowers. Considering the use of S. canadensis in phytotherapy, water extracts from goldenrod leaves and inflorescences had a negligible share of the analysed metals (on average about 1% or less) in the recommended daily allowances (RDAs).

Opis:: The objective of this study was to determine the effects of various concentrations of water extracts prepared from the fresh or dry matter of lemon balm on Sitona lineatus L. and Aphis fabae Scop. behaviour. The assessment pertaining to the feeding intensity of beetles was carried out by measuring the surface of feeds caused by S. lineatus. While examining the effect of extracts on A. fabae, the mortality of wingless female and aphid larvae was determined. In the studies on the olfactory reaction glass olfactometer "Y tube" and 4 armed arena olfactometer were used. The results of the experiment showed that the water extract prepared from dry matter of lemon balm with 2% concentration limited the feeding of both female and male of S. lineatus. The increase in the mortality of the black bean aphid females and larvae was obtained only after applying the extracts from fresh and dry matter at highest concentrations. The evident deterrent reaction of the odour substances obtained from the lemon balm plants towards the beetles of S. lineatus, could find application in ecological farms via introducing the plant as an accompanying crop to the main crops. The winged individuals of A. fabae did not react to the abovementioned factor.

Opis:: The experiment presented in this article contributed to the assessment of the potential applicability of plant extracts for insoil treatment of leguminous plant seeds. Germination capacity of yellow lupine (Lupinus luteus L.) ‘Taper’ variety and field pea (Pisum sativum L.) ‘Milwa’ variety seeds was assessed after pre-treatment of the seeds with aqueous extracts of green plants selected in earlier in vivo laboratory tests. The extracts consisted of garlic (Allium sativum) bulb infusion for the treatment of yellow lupine seeds and dense-flowered mullein (Verbascum thapsiforme) flowers infusion for the treatment of field pea. Direct-soil germination of seeds was assessed in three combinations. The first combination used as the control combination consisted of non-treated seeds being sown into the soil; the second combination consisted of seeds pre-treated with plant extracts before being sown into the soil, while the third combination consisted of non-treated seeds being sown into the soil locally pre-treated with plant extracts. The experiments were carried out for two soils differing in physical characteristics. Direct application of plant extracts into the soil showed to have better impact on germination when compared to the pre-treatment of seeds, with the response observed in field pea being higher than that in yellow lupine. At the same time, probable factors that inhibited germination were also identified.
W pracy wykorzystano wyniki zdolności kiełkowania nasion łubinu żółtego (Lupinus luteus L.) odmiany ‘Taper’ i grochu siewnego (Pisum sativum L.) odmiany ‘Milwa’, po zaprawieniu ich wyciągami wodnymi z roślin zielonych, wybranych we wcześniejszych badaniach laboratoryjnych in vivo. Stymulujące działanie na kiełkowanie nasion wybranych roślin w przypadku łubinu żółtego, wykazał napar z cebul Allium sativum (czosnek zwyczajny), a grochu siewnego napar z kwiatów Verbascum thapsiforme (dziewanna wielokwiatowa). W artykule wymienione wyciągi wodne zastosowano w do oceny wschodów roślin bobwatych w glebie. Próbami badanymi były nasiona zaprawiane w/w wymienionymi naparami i w tej formie wysiewane oraz nasiona niezaprawiane wysiewane w miejscu wcześniejszej aplikacji punktowej naparów. Próbą kontrolną były nasiona niezaprawione wysiane do gleby bez aplikacji wyciągów. Badania przeprowadzono w dwóch różnych rodzajach gleby. Pochodziły one z upraw ekologicznych oraz konwencjonalnych. Stwierdzono, że w warunkach glebowych na wschody roślin bobowatych lepiej działało aplikowanie wyciągów do gleby, a nie na nasiona, przy czym lepiej zareagowały nasiona grochu siewnego. Gleba z ekologicznego systemu gospodarowania okazała istotnie lepsza dla wschodów wybranych roślin.

Opis:: Presented work aimed at estimating potential applications of water extracts of stinging nettle leaves (Utrica dioica L.), birch (Betula verrucosa Ehrh.) bark and walnut (Juglans regia) leaves in protection of beetroot (Beta vulgaris var. conditiva) and root parsley (Patroselium crispoum) against fungal diseases. Field experiments revealed a considerable limiting of Cercospora leaf spot (Cercospora beticola) and powdery mildew (Erysiphe umbelliferarum) development in effect of the applied plant water extracts. However, the extract from the nettle leaves revealed the highest efficacy in the diseases limiting. Soil application of the tested plant water extracts much more inhibited the intensity of infection with C. beticola and E. umbelliferarum extracts than foliar application.
Celem niniejszej pracy była ocena możliwości wykorzystania wodnych wyciągów roślinnych z ziela pokrzywy zwyczajnej (Utrica dioica L.), kory brzozy brodawkowatej (Betula verrucosa Ehrh.) i liści orzecha włoskiego (Juglans regia) w ochronie buraka ćwikłowego (Beta vulgaris var. conditiva) oraz pietruszki zwyczajnej korzeniowej (Patroselinum crispum) przed chorobami grzybowymi. W badaniach polowych stwierdzono istotne ograniczenie rozwoju grzybów Cercospora beticola (chwoscik buraka) i Eryspiphe umbelliferarum (mączniaka prawdziwego pietruszki) pod wpływem zastosowanych wodnych wyciągów roślinnych. Jednak najwyższa skuteczność w ograniczeniu chorób wykazał wyciąg z ziela pokrzywy. Doglebowa aplikacja testowanych wodnych wyciagów roślinnych w porównaniu z nalistną istotnie silniej ograniczała nasilenie porażenia przez C. beticola i E. umbelliferarum.

Opis:: Celem badań była ocena zawartość metali ciężkich w wyciągach wodnych sporządzonych z osadów dennych, które potencjalnie mogą być składowane w środowisku lądowym. Do badań pobrano osady ze zbiornika zlokalizowanego na terenie miasta Rzeszów w woj. podkarpackim. W niniejszych badaniach wykazano, że ryzyko zawiązane z wymywalnością metali ciężkich podczas składowania niezanieczyszczonych osadów dennych może stanowić zagrożenie dla środowiska. Zatem wydobyte osady z dna zbiornika rzeszowskiego powinny być składowane w warunkach kontrolowanych.
The aim of study was to assess the content of heavy metals in water extracts prepared from the bottom sediment, which potentially can be stored in the terrestrial environment. Sediments were collected from reservoir located in the city of Rzeszow in the province Podkarpackie. In this study was shown that the risk tied with to leaching of heavy metals during storage of uncontaminated sediments can be a threat to the environment. In the present study demonstrated that the risk tied to leaching of heavy metals during storage of uncontaminated sediments may pose a threat to the environment. It is also bottom sediment extract from the Rzeszów reservoir should be stored in controlled conditions.

Opis:: The aim of this study was to determine the effect of water extracts prepared from fresh and dry matter of winter savory (Satureja montana L.) on mortality of wingless females and larvae of black bean aphid (Aphis fabae Scop.). The experiment was conducted in the laboratory, in six replicates. Dry extracts were prepared at concentration of 2%, 5% and 10%, while the fresh plant at concentration of 10%, 20% and 30%. Stomach poisoning of extracts was determined by soaking broad bean leaves in the respective solutions, and then determining mortality of wingless female and larvae feeding on leaves thus prepared at 12 hour intervals. The results of the experiment showed that the extract prepared from dry matter at the highest concentration (10%), as well as the extracts from fresh matter at concentration of 20% and 30% contributed to an increase in mortality of wingless female of black bean aphid. Meanwhile, extracts prepared from both dry and fresh matter at two highest concentrations caused an increase in mortality of larvae of this pest. Furthermore, with increasing concentrations of analysed extracts prepared from both fresh and dry matter of winter savory, their negative effect on wingless females and larvae usually increase.

Opis:: The objective of this study was to determine the effects of various concentrations of water extracts prepared from the fresh or dry mass of lemon balm on the feeding of Colorado potato beetle larvae in L2 and L4 stages. The extracts from the dry matter were prepared at the concentrations of 2%, 5% and 10% and from the fresh matter at the concentrations of 10%, 20% and 30%. The feeding intensity assessment was conducted by dipping leaves of potato in respective solutions of the extracts and determining the mass of food consumed by larvae, as well as the changes of larvae body weight. In the studies on the olfactory reaction of adult insects, a glass “Y-tube” olfactometer was used. The feeding by L4 larvae of Colorado potato beetle was effectively limited by the extract prepared from the dry matter of lemon balm with 10% concentration. The larvae at L2 stage turned out to be more susceptible to the effects of extracts – the extracts in almost all used concentrations limited the feeding of the studied pest. The body weight gain in L2 and L4 larvae of Colorado potato beetle were effectively limited by the extracts prepared from the dry plants of lemon balm in as low concentration as 5%. However, the effect of extracts prepared from the fresh matter of lemon balm plants was effective in limiting the body weight gain of L4 larvae at the minimum concentration of 20%, whereas for L4 larvae the effective concentration was 30%. The evident deterrent reaction of odour substances originating from lemon balm plants towards the females of Colorado potato beetle was found. The males did not react to the above-mentioned factor.
