The field research were carried out in 2021–2022, in Mariza sugar beet cultivar. The aim of the study was to develop an alternative weed control program without lenacil. The tested mixtures containing metamitron, ethofumesate, triflusulfuron-methyl, clopyralid, dimethanamid-P and quinomerac, used in various combinations together with the Atpolan BIO 80 EC Premium adjuvant, effectively controlled Chenopodium album up to phase 1 of the true leaf pair (BBCH 11). The absence of ethofumesate in the composition of mixtures or the use of metamitron (1050 g/ha) with triflusulfuron-methyl (15 g/ha) results in a deterioration in the effectiveness of combating Ch. album indencisive results. The addition of dimethanamide-P and quinomerac to the mixture of metamitron, ethofumesate and clopyralid gave inconclusive results. Depending on the year of the study, comparable control efficiency was obtained, oscillating in the range of the mixture of metamitron with ethofumesate, or a negligible improvement. The conducted research proved that the withdrawal of lenacil affect the deterioration of the effectiveness of combating Ch. album.
田间研究于2021-2022年在Mariza甜菜品种上进行。这项研究的目的是开发一种不使用lenacil的替代杂草控制方案。所测试的混合物含有异氰胺、乙氧呋喃酯、三氟呋喃-甲基、氯吡喃、二甲酰胺- p和喹美拉酸,与Atpolan BIO 80 EC高级佐剂一起以不同的组合使用,有效地控制了Chenopodium album,直到真叶对(BBCH 11)的第1期。混合物成分中不含乙硫醚,或将异氰胺(1050克/公顷)与三氟呋喃-甲基(15克/公顷)混合使用,会导致防治甲烷的效力下降。将二甲酰胺- p和喹美酸加入到偏氨氮、乙氧膦酸酯和氯吡啉的混合物中,结果不确定。根据研究年份的不同,获得了相当的控制效率,在偏氨氮与乙氧膦酸盐混合物的范围内振荡,或者可以忽略不计的改善。经研究证实,lenacil的停药会影响抗胆碱的疗效恶化。

The aim of the study was to assess the impact of the use of plant protection products on the freshwater ecosystem in the production of maize for grain in different soil tillage systems. The analyzes were performed on the basis of data on chemical protection of maize in conventional tillage, reduced tillage and direct sowing. The data were obtained from 15 selected farms located in the Wielkopolskie Voivodeship. The studies were conducted in accordance with the life cycle assessment methodology. Using the PestLCI 2.08 model, emissions to the environment from the use of plant protection products were determined. The calculated emissions were used to assess the freshwater ecotoxicity potential using the USEtox 2.02 model. It was found that in all soil tillage systems, the largest stream of emissions of active substances to the environment was the amount of substances available for leaching and surface runoff, followed by emissions to air and emissions to groundwater. Herbicides were the main source of emissions from plant protection products used. A greater threat of toxic effects on the freshwater ecosystem was observed on farms producing maize for grain in direct sowing due to the greater use of herbicides than on farms with conventional and reduced tillage.

The aim of this study was to compare the production-economic results of three edible potato cultivars (Eurostar, Jurek and Mazur) taking into account two different ways of plantation care against weeds. The first way of protection included only mechanical treatments – weeding was performed three times: twice weeding before emergence and once weeding combined with harrowing. The second method of plantation care included double dunging and application of a plant protection product – herbicide, the active substance of which is clomazone (60 g/l) and metribuzin (233 g/l). Before emergence, weeding was applied twice and immediately after the last weeding – about 7 days before the appearance of the first potato plant emergence (BBCH 00–08) a chemical treatment with the herbicide at a dose of 1.5 l/ha was performed. The research material consisted of tubers of three edible potato cultivars from a two-year field experiment (2021–2022). Production value, cultivation costs and gross margin were calculated for the three tested edible potato varieties (Eurostar, Jurek and Mazur) on average for the two years of the study (2021–2022). Mechanical and chemical treatments provided both higher yields of all cultivars and a level of gross margin.

Black locust (Robinia pseudoacacia L.) is characterized by fast growth, low environmental requirements and aesthetic values and therefore it has become a very popular tree planted in forest and urban areas. In recent years, altered shape trees with virus-like symptoms on their leaves have been observed. Therefore, the aim of this work was to identify the virus species potentially causing visible symptoms. During the surveys carried out in 2016–2019, 683 black locust samples were collected. Out of 223 identified virus isolates peanut stunt virus (PSV) (58.7%) was predominant, followed by strawberry latent ringspot virus (SLRSV) (27.8%) and tomato black ring virus (TBRV) (13.5%). The occurrence of mixed infection was also recorded. Annual observation of infected trees confirms the negative impact of viruses on their growth and general condition, leading in many cases to dieback and felling of trees.

The aim of the study was to determine the effect of copper application in combination with organic materials on the genus composition and the intensification of the occurrence of entomopathogenic fungi in the soil. The three-year pot experiment was carried out in greenhouse conditions. The experiment was set up in a completely random design, taking into account two factors: copper dose and organic fertilization. Soil samples for the tests were collected in the third year of the experiment, in spring (before the beginning of vegetation) and in autumn (after harvesting the last crop). The experimental plant was cocksfoot, Amera cultivar. Entomopathogenic fungi from individual research objects were isolated by sowing on a selective substrate. The results were expressed as the number of CFUs of each genus of entomopathogenic fungus in 1 g of soil. The presence of entomopathogenic fungi of the genus Beauveria, Metarhizium, Cordyceps and Lecanicillium was found in the soils collected from the experimental sites, where the dominant genus was Metarhizium spp. In the spring period of conducting the research, the level of copper application affected the number of CFU in a different way, while in the autumn the application of copper at a dose of 200 mg/kg of soil was a level that did not show any toxic effects, and even stimulated the growth of fungal colonies of the genus Beauveria, Metarhizium, Cordyceps in relation to a copper dose of 100 mg/kg.

Entomopathogenic nematodes in the family Steinernematidae (Filipjev, 1934) and Heterorhabditidae (Poinar, 1976) include more than 90 species and are symbiotically related to bacteria in the genera Xenorhabdus (Poinar, 1979) and Photorhabdus (Boemare, 1993). These nematodes are recognized as promising agents for biological control of many insect pest species in crops. The nematodes act as vectors, allowing the bacteria to enter the insect’s body, while the bacteria, after killing the insect, provide the nematodes with continued access to food and an environment for reproduction. Xenorhabdus and Photorhabdus bacteria are closely related phylogenetically, but differ in their host specificity and production of different antibiotics and insecticidal toxins. Due to this symbiosis, they have been successfully implemented in integrated pest management programs around the world due to their strong insecticidal properties and wide range of action. This work presents a review of the symbiosis between bacteria and nematodes and their relationship in biological plant protection.

Climate changes observed for many years adversely affect the development of crops, but also create conditions for the development of individual diseases or their complexes, which so far have not found favorable conditions fot their development. One of such complexes is potato early dying (PED). The fungus Verticillium dahliae is considered to be the main culprit of this disease, but other culprits of PED include Colletotrichum coccodes (Wallr.) Hughes, Verticillium albo-atrum Reinke & Berthold and Fusarium spp. and pectynolytic bacteria Pectobacterium carotovorum subsp. carotovorum. Nematodes Paratylenchus penetrans (Cobb) Sher and Allen play an important role in stimulating the disease and increasing losses. The disease is common in potato-growing areas, causing losses of up to 50%. Due to large amount of infectious material and the possibility of long-term survival in the soil and the wide range of hosts, combating its harmfulness requires the use of all available methods.

The microplot experiment was carried out on two soils (clay and sandy) with spring wheat and fodder pea. In the experiment, the effect of a granular product made of basalt dust and elemental sulphur with a sulphur content of 1.5% was tested. Fertilization of wheat with sulphur in the dose of 30 kg/ha S and pea in the dose of 20 kg/ha S in the form of basalt-sulphur granulate resulted in a significant increase in the content of methionine, cystine and protein in wheat grain on sandy soil. However, no increase in the content of these amino acids and protein in pea seeds was observed. Moreover, an increase in the content of sulphur in wheat grain and straw as well as in pea straw was noted. The use of sulphur in combination with basalt dust did not lower the pH of any of the experimental soils.

The aim of the study was to evaluate the effect of the cultivation system on the rate of degradation and movement of terbuthylazine in the soil. Model experiments were carried out on soil taken from the field, parts of which were differentiated for 3 years in terms of the cultivation system: conventional (with pre-winter ploughing), reduced (disk harrow + tillage unit) and zero tillage (no tillage – application of glyphosate-containing herbicide + direct sowing). The soil was collected with a Van der Horst core sampler into the columns. In a stationary spray chamber, a herbicide containing terbuthylazine was applied at the recommended dose of 500 g/ha. On the basis of the conducted research, it was found that terbuthylazine is a substance with medium persistence in soil (DT50 = 27–34 days). This substance shows the slowest degradation in soil with a zero tillage system. On the other hand, the lack of disturbing the soil structure has a positive effect on the mobility of the herbicide, allowing it to move faster outside the plant root zone.

For the preservation of biological diversity of soil microorganisms, including entomopathogenic fungi which are natural enemies of pests, areas that are subject to anthropogenic transformation as little as possible are of great importance. River valleys may be such areas. The aim of the study was to identification of types of entomopathogenic fungi, as well as to investigate the intensity of their occurrence in the upper genetic levels of meadow muck-glial soils located in the Liwiec river valley. The material for the research was soil samples collected in October 2018 and May 2019, in the upper reaches of the Liwiec river. Insecticidal fungi were isolated from individual genetic levels of the soils under study using the selective substrate isolation method. In the course of the research, insecticidal fungi of the genus were isolated: Beauveria spp., Metarhizium spp., Isaria spp. and Lecanicillium spp., with only Beauveria spp. and Lecanicillium spp. being found in the autumn. The greatest number of infection units was formed by the fungus Beauveria spp. and the greatest intensity of its occurrence was found in the turf level of the soils studied.
