The assumptions of integrated pest management put great emphasis on the development of non-chemical methods which increases the interest in biological methods and the search for microorganisms that would be an alternative to the most frequently used fungicides. The aim of the experiments was the isolation of the compost bacteria, in vitro determination of their fungistatic activity against some pathogenic fungi of the genus Fusarium, Alternaria, Sclerotinia, Botrytis, Rhizoctonia and Pythium and identification of selected isolates. From the backyard compost, 44 bacterial strains were isolated and assessed for the fungistatic properties by the well diffusion method. The obtained results allowed for the selection of 12 isolates of compost bacteria, characterised by the broadest and the strongest fungistatic activity spectrum against tested fungi. Identification of bacterial isolates by: MALDI-TOF mass spectrometry and 16S rRNA gene sequencing methods showed their belonging to the species Bacillus subtilis, Alcaligenes faecalis, Stenotrophomonas maltophilia and Serratia liquefaciens.

The main aim of the study was to become acquainted with the daily and seasonal dynamics of flights of ten economically important aphid species in Johnson’s suction trap in Winna Góra in 2018–2020. In the 2018 a total of 3.584 winged aphid specimens were caught, in 2019 – 5.049, and in 2020 – 9.411. Five aphid species were noticed as the most numerous: Rhopalosiphum padi, Sitobion avenae, Aphis fabae, Myzus persicae and Anoecia corni. Members of bird cherry-oat aphid (R. padi) dominated in all the years of observation. The number of caught aphids depended on the weather conditions in individual decades. Harvest data, in conjunction with the course of temperatures and rainfall in individual years, may constitute the basis for establishing short- and long-term forecasts of the emergence of economically important aphid species.

An effective use of information systems in farm management brings a number of benefits, ranging from the most general, in the form of management of the farm as a whole and improvement of information flow, through measurable benefits reflected in the improvement of economic indicators on the farm. The aim of this study is to present the issue related to the practical use of decision support systems on the example of the Pest Warning System or the emerging decision-making platforms used in agriculture. The subject of the project with the acronym eDWIN will be the creation of a national IT system for plant protection, which will significantly affect the quality and quantity of food produced in Poland. The system will be a work tool for farmers, advisors, support for other food producers and consumers. The project is an answer to the needs related to production efficiency and the quality of plant protection. This article presents the results of two-year research on the implementation of the system in five Voivodeship agricultural advisory centers and connection of knowledge and collected field observations posted on the Platform of Pest Warning System.

The aim of the study was to compare the results of computer simulations carried out using two mathematical models developed for estimating the length of the incubation period of Puccinia recondita f. sp. tritici, the perpetrator of the leaf rust in wheat. Both models were developed using the exponential function based on the results of experiments carried out in 2013–2015. Model 1 determines the length of the incubation period based on average daily air temperatures, while model 2 based on temperature values recorded in an hourly interval. The reliability of the models was assessed by comparing the simulation results with the actual dates of onset of disease symptoms on plants inoculated in the experiments carried out in 2016–2018. The results of computer simulations using the developed models were similar with the actual dates of onset of disease symptoms. Slightly better results were obtained for the model determining the length of the incubation period based on the value of temperature recorded in the hourly interval.

The aim of the conducted study was an evaluation of plant protection products consumption and the cost-effectiveness of their usage in the selected farms in Wielkopolskie Voivodeship. The source material was the results of questionnaire surveys carried out in 2017. The study included farms with an arable land (AL) of over 10 ha. Due to analytical purposes the farms were divided into five groups (I–V) depending on the area of arable land: 10–20, 21–30, 31–50, 51–100 and above 100 ha. The amount of chemical plant protection was varied and depended on the farm size and crop species. The highest consumption of plant protection products, expressed in kg of active substance (a.s.) per area unit, characterised winter wheat cultivation (2.34 kg of a.s./ha), corn and mixed wheat was lower by 12 and 13% (respectively 2.06 and 2.03 kg of a.s./ha), and the lowest was cultivation of winter triticale and spring barley (respectively 1.91 and 1.75 kg of a.s./ha). The cultivation of the analysed species had the highest consumption of herbicides, much smaller of fungicides and the smallest of insecticides. The most favourable value of the cost coverage index was obtained in spring barley cultivation in farms with 21–30 ha of arable land (12.9) and corn cultivation in farms with arable land of 31–50 ha (12.9). The highest yield to cover the costs of chemical protection was allocated to the cultivation of winter triticale (average 11.5%), the lowest in the cultivation of winter wheat (8.6%).
所进行研究的目的是评估大波兰省选定农场的植物保护产品消费及其使用的成本效益。资料来源于2017年开展的问卷调查结果。该研究包括耕地(AL)超过10公顷的农场。由于分析目的，根据耕地面积将农场分为五组(I-V): 10-20、21-30、31-50、51-100和100公顷以上。根据农田规模和作物种类的不同，化学植保的用量也不同。植物保护产品的最高消耗，以每面积单位的活性物质kg (a.s.)表示，冬小麦种植(2.34 kg a.s./ha)，玉米和混合小麦的消耗分别降低了12%和13%(分别为2.06和2.03 kg a.s./ha)，最低的是冬季小黑麦和春大麦的种植(分别为1.91和1.75 kg a.s./ha)。所分析品种的栽培除草剂用量最高，杀菌剂用量少得多，杀虫剂用量最少。耕地面积为21 ~ 30 ha的春大麦种植和耕地面积为31 ~ 50 ha的玉米种植的成本覆盖指数分别为12.9和12.9。与化学防护费用相比，种植冬季小黑麦的产量最高(平均为11.5%)，种植冬小麦的产量最低(8.6%)。

Studies carried out in the years 2012–2018 on Cieszyńskie Foothills fields (26 localities in 7 boroughs) with maize in order to determine weed species and segetal association. Phytosociological relevés were made using Braun-Blanquet method with recommended parameters and coefficients (number of records, abundance, covering). 124 weed species were observed in maize, with a predominance of species from classes not associated with segetal association. Species from Stellerieta mediae class represented 44% of all species. Segetal species occurred with taxa from other phytosociological classes (55%) which were dominated by species belonging to meadow communities from Molinio-Arrhenatheretea and Artemisietea vulgaris class, presenting ruderal species and a few species from other classes, including Agropyro-intermedio repentis, Bidentetea tripartiti, Isoëto-Nanojuncetea, Querco-fagetea, Rhamno-Prunetea, and Trifolio-Geranietea sanguinei.
