For over 5 years, in the countries of north-western Europe, there has been a growing threat of a new pest, which does not yet have a Polish name, and whose presence has been confirmed from production facilities in Poland in the last 3 years. Nesidiocoris tenuis is a true bug that pierces the plant and sucks the sap from the phloem. In places of feeding, tissue necrosis occurs, leading to deformations, brown rings and, consequently, inhibition of the growth of punctured plant parts. Paradoxically, in the Mediterranean countries, this insect has been treated as a useful predator for years and, as part of biological protection, used to fight the tomato moth Tuta absoluta.

The aim of the study was a multidimensional analysis of the occurrence of pesticide residues in fruit samples (87) within the framework of official control (68, WIORiN) and cross-compliance control (19, ARiMR). There was an assessment of the frequency of detection of chemical groups and individual active substances (a.s.), the level of concentrations and estimation of the magnitude of exceedances of permissible standards (MRLs), as well as diagnosis of multi-residue samples. The practical purpose of the studies conducted was to assess compliance by producers with the regulations for the application of the pesticide residues. In 45% (WIORiN) and 9% (ARiMR) of the samples, residues of pesticides were found. MRL exceedances were recorded in 1% of the samples tested. Samples with a non-recommended a.s. accounted for 5% of samples. Of the 516 labeled pesticides, 26 a.s. were detected, mainly fungicides. The highest level was recorded for boscalid (1.6 mg/kg) in the blueberry sample. Residues of pesticides were most often detected in strawberries (18%). The highest number of compounds was detected in cherries, where nine a.s. were determined. The presence of multi-residue samples was noted (44%), of which samples with two residues were the most numerous (11%). The results obtained from the study show the importance of controlling residues of pesticides in fruits, which require frequent use of chemical pesticides due to attack from agrophages, in order to guarantee food quality and safety.

Common wheat is an economically important crop, cultivated mainly for food purposes. During the growing season, wheat crops are exposed to feeding by numerous animal pests: insects, snails and plant parasitic nematodes. Among phytophagous nematodes, cystforming nematodes of the genus Heterodera and root-knot nematodes of Pratylenchus are recognized as pests of the crop. Spring observations of cultivation of common wheat in the winter form showed clusters of plants with symptoms of growth inhibition. Tylenchorhynchus dubius (Bütschli, 1873), Geocenamus microdorus (Geraert, 1966), Paratylenchus projectus Jenkins, 1956, Trichodorus primitivus (De Man, 1880) and Trichodorus viruliferus Hooper, 1963 were isolated from the soil of wheat root zone, pointing to them as a potential threat to the proper vegetation of the crop. Therefore, there is a message to start monitoring winter wheat crops for the presence of plant-parasitic nematodes, especially in the face of ongoing climate change.

Dry rot of tubers is one of the dozens of soil-borne diseases that cause severe yield losses of economic importance. The disease is caused by fungi of the Fusarium genus, which commonly live in the soil, and feed on organic matter as saprotrophs. Their widespread occurrence means they also inhabit other economically important crops: wheat, rye, oats, barley, triticale, and maize. Fusarium fungi are currently among the world’s most pathogenic and phytotoxic microorganisms. They cause numerous potato crop losses, and the disease’s course includes field and storage.

Urban greenery is defined by the high density and species diversity of plants. As such, it is a habitat for various groups of insects, including pests and insectivores. This study aims to determine the species composition and abundance of parasitoids of the subfamily Pimplinae in urban green spaces. The study was conducted between 2009 and 2016 in Gdynia. Sweep-net sampling and collecting dead insects from the beach were used. A total of 442 specimens belonging to 45 species of Pimplinae were collected. They represented 66.18% of the species listed in this habitat and 32.61% of the species found in Poland. The dominant species included Tromatobia lineatoria (14.26%), Scambus inanis (10.41%), Zaglyptus varipes (7.92%), Tromatobia ovivora (7.70%), Acropimpla pictipes (6.57%), Scambus calobatus (5.43%) and Gregopimpla inquisitor (5.21%). Three trophic groups were distinguished among the parasitoids, including parasitoids of phytophagous insects, i.e. Arachnida and Aculeata. Parasitoids of phytophagous insects were the most abundant [34 species (75.55%)].

The results of a three-year field experiment in the cultivation of the edible potato of the Oberon cultivar with the use of five methods of weed control and nutrition with biostimulators were presented: control object – mechanical care, Avatar 293 ZC (chlomazone + metribuzin), Avatar 293 ZC and PlonoStart, Avatar 293 ZC and Aminoplant and Avatar 293 ZC and Agro-Sorb Folium in a split-plot system, two-factor in three repetitions. The aim of the study was to analyze the economic effectiveness of five methods of care and nutrition with biostimulators in combating weed infestation on a potato plantation of the Oberon cultivar carried out on medium soil, which was determined on the basis of indicators adopted in plant protection, such as: cost coverage index Wpk, which was on average 3.75 and profitability ratios E1 and E2, which averaged 20.34 and 5.68%. Profitability ratios showed that the mechanical and chemical protection of potatoes of the Oberon variety with the use of herbicide and biostimulators was profitable.

Biofertilizers, including biofertilizers, seem to be one of the best ways to increase or maintain the current rate of food production, while ensuring the stability of the natural environment. The aim of the study was to determine the effect of selected biofertilizers containing humic substances on the in vitro growth of entomopathogenic fungi of the genus Beauveria and Metarhizium in the context of their combined use in plant cultivation and protection. The effect of biofertilizers Rosahumus, Liqhumus 18 and BNB on the growth of colonies of four selected species of entomopathogenic fungi Beauveria bassiana, Beauveria brongniartii, Metarhizium anisopliae and Metarhizium flavoviride was tested in laboratory conditions. Biofertilizers were added to the Sabourauda (SDA) culture medium at the recommended field dose. Colony growth observations were made every 5 days until day 20th by measuring colony diameters in mm. The conducted research showed that the biofertilizers containing humic substances used in the experiment acted in a different way on the growth of insecticidal fungi of the genus Beauveria and Metarhizium. Among the tested biofertilizers, only the BNB preparation showed an inhibitory effect on all the tested isolates. The greatest stimulating effect of the tested preparations was found in relation to the fungi B. bassiana and M. flavoviride, while the most sensitive species turned out to be M. anisopliae.

Leaf spot of oat caused by the fungus Pyrenophora chaetomioides Speg. (Drechslera avenae anamorph) (Eidam) (Scharif) is one of the most harmful and widespread diseases of oat. Field experiments were carried out in 2012–2016 in breeding fields in Kopaszewo. The aim of the study was to assess the susceptibility of oat cultivars to the infestation of D. avenae and to determine its influence on the yield. The incidence of the disease was dependent on the variety and varied between the study years, indicating the effect of a variation × year interaction. However, no statistical differences were found between the varieties of a given form. The cultivar least infested by the fungus D. avenae was the naked cultivar Nagus. In the group of hulled varieties Bingo and Zuch showed the highest resistant. The highest yield value was obtained in cultivation of the Arden hulled variety.

The paper presents the most important issues concerning the breeding of apple trees resistant to fire blight, which creates great opportunities to increase the efficiency of apple fruit production without the use of other protection methods, including the chemical treatment. The phenotypic assessment of susceptibility of apple genotypes to the disease is based on observations on the occurrence of symptoms in field and/or closed facilities, e.g. in the greenhouse. Molecular biology methods, including identification of resistance markers, and biotechnology are valuable tools to accelerate the breeding process. Breeding programs conducted in various research centers around the world use wild species of the genus Malus and commercial cultivars of apple. Apple rootstocks with very high resistance to fire blight (USA) and a number of scab-resistant cultivars, also showing high resistance to the disease (Germany, Switzerland) have already been bred. In recent years cultivar Early Szampion and clone No. 69 (J-2003-05) have been bred in Poland. Both genotypes are characterized by a very high resistance, and produce attractive tasty fruit. They have the prospect of being used in breeding programs and commercial plantings.

Since Poland has joined the structures of the European Union (EU), legal regulations at the EU level allow marketing of plant varieties registered in any country of the community. As part of the Post Registration Variety Trials (PRVT) in the Wielkopolska (Greater Poland) voivodeship, the analysis of the interaction of winter triticale cultivars for: height, lodging, diseases, yield and thousand kernel weight in growing seasons 2017–2019 was performed. For farmers, the most important and valuable effect of the research conducted in the PRVT system is the annual “List of varieties recommended for cultivation in the voivodeship”. The main purpose of PRVT research is to help farmers in accurate selection/choice of the most valuable varieties for cultivation, adapted to local conditions. This type of research provides users with continuous information about the variety value for cultivation and use, including their reaction to various agrotechnical factors.
