Opis:: Soybean [Glycine max (L.)], one of the most important crops in Argentina, is commonly infected by Colletotrichum truncatum, the causal agent of anthracnose. Tagetes filifolia essential oil (EO) is presented as a natural approach to minimize the dose of chemical fungicides applied to the crop. The fungus Trichoderma harzianum is used as a biocontrol agent because of its ability to produce secondary metabolites that destroy cell walls of phytopathogenic fungi. However, its performance can be affected when it is exposed to chemical fungicides. The objective of this work was to evaluate the antifungal activity of T. filifolia EO both individually and combined with chemical fungicides against C. truncatum, and its effect on T. harzianum. Fungi were isolated from soybean crops. The following pesticides were assessed: carbendazim (F1), difenoconazole (F2) and trifloxystrobin + cyproconazole (F3). The EO was obtained from native plants and its chemical composition was analyzed by gas chromatography–mass spectrometry (GC–MS). The minimum fungicide concentration (MFC) was determined for each compound. Fungicides were combined with the EO to look for combinations that allowed a reduction of pesticide doses. Among fungicides, F1 showed the strongest antifungal activity against C. truncatum (MFC = 0.25 µl ⋅ l–1) and T. harzianum (MFC = 1.5 µl ⋅ l–1). The sensitivity of both fungi to the EO was lower than to fungicides. The EO presented MFCs of 6,000 and 9,000 µl ⋅ l–1 against C. truncatum and T. harzianum. The EO and F1 affected the growth of T. harzianum at concentrations that controlled C. truncatum (31 and 10%). Eight combinations of fungicides and the EO allowed fungicide concentration reductions of up to 80%, although the growth of the biocontrol strain was also affected. The results demonstrated that T. filifolia EO can be used to control anthracnose and reduce doses of chemical fungicides applied to soybean crops. Its effect on T. harzianum should be considered in the design of integrated pest management strategies.

Opis:: It was expected that there would be a relationship between plant density and arrangement within soybean plantations and ground beetles due to changes of abiotic habitat conditions. The aim of this study was to determinate the effect of different plant arrangements of soybean plants on the abundance and species diversity of ground beetles (Coleoptera, Carabidae). The studies were conducted from 2015 to 2017 at the Experimental Research Station, Wrocław, Poland. The occurrence of beetles was examined on soybeans, growing in four different treatments: row spacing of 15 cm or 30 cm, and seeding density of 50 or 90 seeds per m2. The experiment was conducted in a split-plot design in four replicates. Ground beetles were collected with 16 pitfall traps, with one trap in the middle part of each plot. The obtained results show that the general number of ground beetles was similar between the treatments. Some minor effects were found in species number, which was higher in the lower row spacing treatment. Only less abundant species were significantly affected. The most abundant species in all years and treatments were Pseudoophonus rufipes, Harpalus affinis, Calathus fuscipes and Pterostichus melanarius. The abundance of the above-listed common ground beetle species did not differ significantly between treatments.

Opis:: The production of domestic protein for feed in Poland is insufficient. The import of feed raw materials, especially soybean, which is genetically modified (GM) is necessity. In 2016, Poland imported about 2 million tonnes of GM soybean. In Poland was introduced a ban for using and production of GM feed (Law – animal feed from 2006). This ban has already been suspended few times, mainly due to the fact, that the complete replacement of imported GM soybean meal with other components was impossible. The Minister of Agriculture and Rural Development appointed “Team for alternative sources of protein”, responsible for finding solutions that will impact on reducing imports and will increase the share of domestic sources of protein in animal feed. To achieve this aim research are needed to indicate plants and their possibilities for using. The aim of the article is to analyse selected feed components such as: soybean and rapeseed meal, sunflower meal and oilcakes. This analysis concerns the area of cultivation of soybean, rapeseed and sunflower, purchase costs of meals and oilcakes, properties of these components and foreign trade in Poland.

Opis:: The “second generation” of glyphosate-tolerant soybean (GT2 soybean) was developed through a different technique of insertion of the glyphosate-insensitive EPSPs gene, in comparison with “first generation” of glyphosate-tolerant soybean. However, there is not enough information available about glyphosate selectivity in GT2 soybean and the effects on the quality of seeds produced. The aim of this study was to evaluate tolerance to glyphosate and seed quality of soybean cultivar NS 6700 IPRO (GT2) with cp4-EPSPs and cry1Ac genes, after application at post-emergence (V4). The experiment was conducted in a randomized block design with four replicates and seven treatments, or rates of glyphosate (0; 720; 1,440; 2,160; 2,880; 3,600; 4,320 g of acid equivalent − a.e. · ha−1). Assessments were performed for crop injury, SPAD index and variables related to agronomic performance and seed quality. A complementary trial with the same cultivar and treatments in a greenhouse was conducted in a completely randomized design with four replications. Data analysis indicated no significant effect of glyphosate on V4 on agronomic performance and physiological quality of seeds, for two growing seasons. The soybean cultivar NS 6700 IPRO (GT2), with cp4-EPSPs and cry1Ac genes, was tolerant to glyphosate up to the maximum rate applied (4,320 g a.e. · ha−1) at post-emergence (V4). The quality of soybean seeds was not affected by glyphosate up to the maximum rate applied (4,320 g a.e. · ha−1) at post-emergence (V4).

Opis:: The purpose of the studies conducted in the years 1996-1998 was to determine the quantitative and qualitative composition of bacterial and fungal communities in rhizosphere of soybean cultivated in monoculture and non-rhizosphere soil. Besides, the proportion of bacteria and fungi, which were distinguished by their antagonistic effect towards soil-borne pathogens was established. A microbiological analysis of 1g of dry weight of soil from rhizosphere of soybean resulted in 3.21 x 10⁶ to 8.70 x 10⁶ bacterial colonies and from 70.51 x 10³ to 123.74 x 10³ fungal colonies. In the case of non-rhizosphere soil, 3.50 x 10⁶ to 4.75 x 10⁶ bacterial colonies and 16.16 x 10³ to 51.38 x 10³ fungal colonies were obtained. Besides, soybean cultivation in monoculture had a negative effect on the number of antagonistic isolates of bacteria (Bacillus spp., Pseudomonas spp.) and fungi (Gliocladium spp., Penicillium spp., Trichoderma spp.). Smaller numbers of antagonistic bacteria and fungi in rhizosphere soil of soybean cultivated in monoculture as compared to non-rhizosphere soil, can prove little biological activity, which results in a worse phytosanitaty condition of the soil.
Przedmiotem badań przeprowadzonych w latach 1996-1998 była gleba ryzosferowa soi uprawianej w monokulturze oraz gleba pozaryzosferowa. Analiza mikrobiologiczna wykazała, że w 1 g s.m. gleby ryzosferowej średnia liczebność bakterii oraz grzybów była większa, aniżeli w glebie pozaryzosferowej. W próbach badanych gleb liczebność bakterii z rodzaju Bacillus była zbliżona. W przypadku bakterii z rodzaju Pseudomonas ogólna ich liczebność była prawie trzykrotnie większa w ryzosferze soi, aniżeli w glebie pozaryzosferowej. Badania laboratoryjne wykazały, że znacznie więcej antagonistycznych Bacillus spp., Pseudomonas spp., Gliocladium spp., Penicillium spp. i Trichoderma spp. wystąpiło w glebie pozaryzosferowej, aniżeli w ryzosferze soi. Mniejsza liczebność antagonistycznych bakterii i grzybów w ryzosferze soi uprawianej w monokulturze może świadczyć o małej aktywności biologicznej mikroorganizmów, co przyczynia się do pogorszenia fitosanitarnego stanu gleby.

Opis:: The aim of the present work was to evaluate the selectivity of nicosulfuron, alone and in combinations, applied in post-emergence (V4) of glyphosate and sulfonylurea tolerant (RR/STS) soybean. The experiments were conducted in 2015/16 and 2016/17, in Piracicaba – state of São Paulo (SP). In 2016/17, the experiment was also conducted in Palotina – state of Paraná (PR). The experiment was a randomized block design, with four repetitions and 16 treatments, with combinations of nicosulfuron, glyphosate, chlorimuron, sulfometuron and cloransulam, applied alone or in tank mixture. Crop injury and variables related to agronomic performance were evaluated. Data were subjected to analysis of variance and treatment means were compared by the Tukey test. The results obtained are significant in the positioning of herbicides in RR/STS soybean, since in the five experiments, all the treatments were selective, except for glyphosate + sulfometuron which reduced the yield of a cultivar (CD 2630 RR/STS) in the 2015/16 season.

In group A (n=11) the mixtures were supplemented with soybean selenium proteinate, in group B (n=11) with sodium selenite and in group C (n=11) with Se-enriched yeast (0.3 mg Se per kg in all groups). The use of soybean selenium proteinate resulted in lower retention of Se in tissues (liver, heart, muscle) compared to Se-enriched yeast. Selenium concentrations in tissues achieved by soybean selenium proteinate and sodium selenite were comparable. No differences in serum Se, serum GSH-Px and meat quality traits were found among the groups.

Opis:: Vegetable oils belong to a large group of substances consumed on a daily basis. World vegetable oil production is soaring, reducing the popularity of animal fats. Heavy metals pose a threat to human health. It is estimated that about 80% of the daily dose of heavy metals enters the human body through the consumption of food. Hence, it is necessary to monitor their concentrations in food products. Besides, the presence of heavy metals is thought to have possible negative influence on the quality of oils, especially on their taste and smell. Heavy metals may also accelerate the process of the rancidifiction of oils. Rapeseeds, soybean seeds and linseeds were selected for the analysis because they are one of the most popular oilseeds and at the same time they differ in terms of growing conditions. The analyses of different fractions and the ready-made product were also performed. The aim of the study was to determine the variation in concentrations of heavy metals, iron and manganese in different fractions during production. The significant concentrations of iron, manganese and zinc were observed in oilseeds. It was also shown that during different stages of oil refining the concentrations of metals decrease. The concentrations of metals are compared with those reported in literature.
Oleje roślinne stanowią szeroką grupę produktów stosowanych w codziennej konsumpcji. Ich produkcja i spożycie rosną kosztem bardziej szkodliwych tłuszczów zwierzęcych. Metale ciężkie stanowią zagrożenie dla zdrowia i życia ludzkiego. Przyjmuje się, że około 80% codziennej dawki dostaje się do organizmu człowiek wraz z żywnością. Stąd istnieje konieczność monitorowania ich stężeń w produktach spożywczych. Ponadto uważa się, że obecność metali ma wpływ na właściwości smakowo-zapachowe olejów, a także może przyspieszyć procesy ich jełczenia. Do analizy wybrano ziarna lnu, rzepaku i soi, są to jedne z najpopularniejszych roślin oleistych, a zarazem różnią się warunkami uprawy. Analizie poddano także ich frakcje produkcyjne i gotowy do konsumpcji produkt. Celem pracy było poznanie zmian stężeń metali ciężkich, żelaza i manganu w toku produkcyjnym. Zaobserwowano znaczące stężenia żelaza, manganu i cynku w ziarnach roślin oleistych. Stwierdzono, że proces produkcji skutecznie obniża stężenia metali do bezpiecznego poziomu w ilościach śladowych. Poziom stężeń jest zbliżony do doniesień literaturowych.

Opis:: The purpose of the studies conducted in the years 1996-1998 was to determine the quantitative composition of bacteria and fungi populations in the rhizosphere of spring wheat, winter wheat, potato and soybean, and in non-rhizosphere soil. Besides, the effect of root exudates of these plants on the formation of antagonistic microorganisms is presented. A microbiological analysis found out that 1 g of rhizosphere soil dry weight of the examined plants and non-rhizosphere soil contained from 4.24 x 10⁶ to 5.97 x 10⁶ bacteria colonies on average. The lowest number of bacteria was found in non-rhizosphere soil (4.24 x 10⁶ on average), and the highest in rhizosphere of potato (5.97 x 10⁶ on average). The fewest fungi colonies (28.59 x 10³ on average) were isolated from 1 g of dry weight of winter wheat rhizosphere, and the most (93.41 x 10³) from soybean rhizosphere. Antagonistic bacteria of genera Bacillus and Pseudomonas, and fungi of Gliocladium, Penicillium and Trichoderma genera dominated in winter wheat rhizosphere. Soybean roots exuded the greatest number of aminoacids (1.088 mg/ml of the solution), while spring wheat roots exuded the smallest amount (0.148 mg/ml of the solution). The percentage of aromatic and alkaline aminoacids was the lowest in potato root exudates, whilc the highest was found out in the exudates of winter wheat.
Celem badań przeprowadzonych w latach 1996-1998 było określenie składu ilościowego zbiorowisk bakterii i grzybów w ryzosferze pszenicy jarej, pszenicy ozimej, ziemniaka, soi oraz w glebie pozaryzosferowej. Ponadto starano się wyjaśnić, jaki wpływ na kształtowanie się mikroorganizmów antagonistycznych dla grzybów patogenicznych mogły mieć wydzieliny korzeniowe tych roślin. W wyniku przeprowadzonej analizy mikrobiologicznej stwierdzono, że w 1g s. m. gleby średnia liczebność bakterii i grzybów w glebie ryzosferowej badanych gatunków roślin była z reguły większa, aniżeli w glebie pozaryzosferowej. Antagonistyczne Bacillus spp., Pseudomonas spp., Gliocladium spp., Penicillium spp. i Trichoderma spp. dominowały w glebie ryzosferowej pszenicy ozimej. Najwięcej ogółem aminokwasów wydzielały korzenie soi, a najmniej korzenie pszenicy jarej. Wydaje się, że wydzieliny korzeniowe pszenicy ozimej wykazywały najbardziej stymulujący wpływ na wzrost jednostek propagacyjnych bakterii i grzybów antagonistycznych. Natomiast w ryzosferze soi wystąpiło najmniej antagonistów, co może sugerować hamujące oddziaływanie związków wydzielanych przez korzenie tej rośliny. Wydzieliny korzeniowe pszenicy jarej wpłynęły korzystniej na liczebność antagonistycznych bakterii i grzybów aniżeli wydzieliny korzeniowe ziemniaka.

Opis:: Throughout the world, charcoal rot, caused by Macrophomina phaseolina, is one of the most destructive and widespread diseases of crop plants such as soybean. In this study, the biological control capability of 11 Trichoderma spp. isolates against M. phaseolina was investigated using screening tests. Among all the tested Trichoderma spp. isolates, inhibition varied from 20.22 to 58.67% in dual culture tests. Dual culture, volatile and non-volatile tests revealed that two isolates of Trichoderma harzianum (including the isolates T7 and T14) best inhibited the growth of M. phaseolina in vitro. Therefore, these isolates were selected for biocontrol of M. phaseolina in vivo. The results of greenhouse experiments revealed that disease severity in the seed treatment with T. harzianum isolates was significantly lower than that of the soil treatment. In most of the cases, though, soil treatment with T. harzianum resulted in higher plant growth parameters, such as root and shoot weight. The effects of T. harzianum isolates on the activity of peroxidase enzyme and phenolic contents of the soybean root in the presence and absence of M. phaseolina were determined in greenhouse conditions. Our results suggested that a part of the inhibitory effect of T. harzianum isolates on soybean charcoal rot might be related to the indirect influence on M. phaseolina. Plant defense responses were activated as an elicitor in addition to the direct effect on the pathogen growth.
