Satisfying consumer needs through the production of healthy and nutritious agricultural products is a substantial challenge facing modern agriculture. However, agricultural production should be carried out with care for plant health, biological safety of products, and environmental safety while minimizing the risks to human health. Therefore, the implementation of agricultural practices while respecting these principles is very important for improving the quantity and quality of crops. Additionally, ecosystems have altered as a result of human activities and climate change, resulting in the reduction of biodiversity and creation of new niches where pests can thrive. This is of particular importance in 2020, as the United Nations General Assembly declared this year as the International Year of Plant Health (IYPH), with “protecting plants, protecting life” as a leading subject.
This Special Issue will promote the subject of plant health and emphasize the importance of preventing the spread of pests, including weeds, which cause substantial economic losses. Research articles will cover topics related to the biology and harmfulness of weeds, particularly in connection with crop health, segetal weed communities and their biodiversity, and integrated methods of weed control. For this Special Issue, we welcome all types of articles, including original research, opinions, and reviews.

The influence of farming system on weed infestation and productivity of narrow-leaved lupin (Lupinus angustifolius L.)
Abstract: The modern agricultural industry is facing with many challenges. The main is the production of adequate food for an ever-increasing human population according to sustainable agronomy practice. For this reason agricultural policy of the European Union is recommending legumes cultivation as environment-friendly. The role of legumes is very important in crop rotation because of a lot of benefits: improve soil physical conditions, nitrogen fixation, reduction of erosion from water and wind as well as increasing soil organic matter. A real problem in the cultivation of legumes is weed infestation, so it is important from a practical point of view to define a farming system that will allow them to be reduced. Furthermore it is very important to find the way, how to decrease cost produce of legume to encourage farmers to cultivation of those crops.
The aim of the study was to evaluate weed infestation and productivity of narrow-leaved lupin cultivated under different farming systems (low-, medium- and high-input).
A two–factor field experiment in 2011–2015 at the Experimental Station in Gorzyń (52◦33’53 N, 15◦53’42 E; Poland) was conducted. The first factor consisted farming system: low-input (LI; without fertilization and chemical protection), medium-input (MI; medium level of fertilization and chemical protection) and high-input (conventional-CONV; high level of fertilization and chemical protection). The second factor was cultivar of narrow-leaved lupin: determinate cv. Regent and indeterminate cv. Kalif. Sowing dates depended on soil water conditions in each year of study. The sowing depth was 4 cm and the row space was 18 cm. Plots were drilled with a double disk drill (Great Plains, Solid Stand 10’ equipped with a fluted coulter for residue cutting, a double disk for seed placement, and a press wheel, 3 m wide). Lupin was harvested using a 1.5 m wide Wintersteiger Classic Plot Combine annually in July.
Analysis of weed infestation was carried out two weeks before seed harvesting. Weed density was counted in each growing season with sampling areas of 1 m×1 m quadrates placed randomly on each plot. Weeds were sorted according to species. Plant material was oven dried at 80 ◦C for 48 h and dry weights corresponding to the aboveground biomasses were determined. Weed infestation was expressed as the number and dry mass of weeds per unit area (m2).
Farming system significantly modified the weed infestation. The seed yield depended on weather conditions during growing period of lupin and experimental factors. There was also assessed protein yield. The lowest protein yield was found in 2011 and the highest in 2014. Compare to CONV, LI significantly decreased protein yield (by about 200 kg per ha). Determinate cultivar Regent produced lower protein yield by 100 kg per ha compare to indeterminate cultivar Kalif. Experimental factors did not influence on protein content in seeds, which ranged average from 307 g kg-1 in LI to 317 g kg-1 in CONV independent of cultivars.
Biodiversity in Fields of Grain in South-Eastern Poland
Abstract: The aim of this study was to establish the presence and quantity of weed species in fields of grain in the south-eastern part of Poland. The conducted research will enable the categorisation of segetal flora characteristic for the given crop, and the determination of its quantity and species composition, and thus it will be possible to evaluate the degree of weed infestation of crops in commercial farms from this region. The research was conducted in commercial farms in the Strzyżowski District (49°52′ N, 21°48′ E) in 2018. The evaluation of weed infestation of grain crops was based on a quantitative and qualitative (framework) method and an agro-phytosociological method. The biodiversity of weed communities was measured with the Shannon index prior to grain harvest. The evaluation of crop and weed growth stage was based on the BBCH-scale. Moreover, fresh mass of individual plant species was determined with the weight method. The paper presents the species composition of weeds infesting winter and spring grains. Based on the results of spring research involving the framework method, it was determined that the condition and degree of weed infestation in the objects was very diverse before farmers commenced weed control procedures. The research showed that the majority of weed infestation (70%) involved dicot weeds, whereas monocot weeds were a lesser threat to grain crops. The greatest weed infestation was observed in winter wheat, and the least in oat crops. The most frequent weeds at the farms were Brassica napus L. and Cirsium arvense (L.) Scop. The dominating weed species in individual grain species were: in fields of winter wheat: Anthemis arvensis, Cirsium arvense, Equisetum arvense, Polygonum convolvulus, Apera spica-venti; in spring wheat: Cirsium arvense, Equisetum arvense, Sinapis arvensis; in spring barley: Equisetum arvense, Galium aparine, Avena fatua; in corn: Chenopodium album, Elymus repens, Equisetum arvense, Polygonum convolvulus, Cirsium arvense; in spring triticale: Anthemis arvensis, Apera spica-venti, Equisetum arvense, Lamium amplexicaule, Polygonum lapathifolium oraz Vicia sativa, Vicia cracca, Vicia tetrasperma; in fields of rye: Equisetum arvense and Cirsium arvense.

Changes in the Floristic Composition of Weeds in Potato Cultivation under the Influence of Various Methods of Care
Abstract: The results of the study were based on field experiment carried out in 2007-2009 at the IHAR-PIB experimental Station in Jadwisin on fawn soil with loamy sand granulometric composition. The experiment was based on the method of randomized sub-blocks in a dependent, split-plot system, in three replications. The first-order factor were potato varieties: Irga and Fianna, the second-order factor were methods of weed control: 1) Control object - no chemical protection; 2) Extensive mechanical treatments (every 2 weeks) from planting until rows close; 3) Sencor 70 WG – before potato emergence; 4) Sencor 70 WG + Titus 25 WG + Trend 90 EC – before potato emergence; 5) Sencor 70 WG after potato emergence; 6) Sencor 70 WG + Titus 25 WG + Trend 90 EC – after potato emergence; 7) Sencor 70 WG + Fusilade Forte 150 EC after potato emergence; 8) Sencor 70 WG + Apyros 75 WG 26.5 + Atpolan 80 SC after potato emergence. 300 dm ha-1 of water was used to spray plants with herbicides. In order to compare the effectiveness of the examined control methods, weed infestation was assessed by the quantitative and qualitative method, twice: after closing the rows and just before harvesting the tubers. The number and floristic composition of weeds were determined. Before harvesting the crop, fresh and dry weed was additionally determined. The use of herbicides in reducing weeds, and in particular mixtures of preparations, has enabled a larger spectrum of chemical action and resulted in greater destruction efficiency than mechanical weed control.

Biological and Agrotechnical Aspects of Weed Control in the Cultivation of Early Potato Varieties under Covers
Abstract: Problems with weed infestation under covers were the reason to conduct research on the regulation of weed infestation in potato cultivation for early harvest. The field experiment was carried out in 2015-2017 at the Experimental Station for Cultivar Assessment in Uhnin (51°34 'N, 23°02'E). The experiment was carried out using the method of random subblocks, in a dependent system (split-split-plot). The first order factor was edible potato varieties 'Denar' and 'Lord'. The second order factor was cultivation technologies: A) traditional technology – as a standard object, B) technology using polyethylene film cover, C) technology using polypropylene agrotextile. The third order factor were weed management methods: 1) mechanical as a control object, 2) mechanical and chemical care using Afalon Dispersion 450 SC preparation, 3) mechanical and chemical care using Plateen 41.5 WG herbicide, 4) mechanical and chemical care using a mixture of herbicides Afalon Dispersion 450 SC + Command 480 EC. Studies have shown that good thermal conditions in covered soil promote not only the development of potato plants, but also weeds. The degree of soil coverage in objects covered with covers was much higher than in objects without covers. Mechanical and chemical care proved to be more effective than mechanical care. The best effectiveness in limiting both fresh and dry weed mass in potato cultivation under covers was achieved using mechanical and chemical care using a mixture of herbicides Afalon Dispersion 450 SC + Command 480 EC.
