Abstract

The present study was specifically designed to develop bio-fungicides that may help mitigate reliance on hazardous synthetic chemicals which give rise to environmental safety concerns. A survey (2021–2022) of local fruit markets in Islamabad, Pakistan included morpho-molecular disease identification. It revealed Penicillium chrysogenum as a major phytopathogenic fungi causing fruit rot. The fungicidal action of plant essential oils might be boosted by the technique of application therefore, nanoencapsulation of essential oil and chitosan was performed. To attain the objective of antimicrobial packaging, essential oil and chitosan tablets were encapsulated in spun bond sachets against P. chrysogenum using a sachet volatile phase technique. In vitro screening of nano encapsulated eucalyptus essential oil showed significant inhibition of radial growth of P. chrysogenum colonies at 1.6 mg · ml–1 followed by 1.4, 1.2 and 1.0 mg · ml –1. Results of Gas Chromatography and Mass Spectrometry revealed the presence of eucalyptol in eucalyptus EO as a major antifungal component. An in vivo experiment analyzing the efficacy of essential oil tablets against pre-inoculated peach fruit with P. chrysogenum at ambient temperatures (7–37°C) showed significant reduction in lesion diameter, disease severity and prolonged shelf-life of peaches of more than 2 weeks. The natural ripening process of peach was not affected by the presence of antifungal sachets as no significant alteration in weight loss of fruit was recorded. The suppressiveness of fungal mycelial growth of P. chrysogenum was directly proportional to increases in E. globulus oil concentration. This research may have a significant impact on prolonging the shelf-life of peach fruit.

Abstract

Seed endophytes are potential bioagents for plant protection and growth promoters. The question of the specifics of their isolation in cultural environments is not clear. The purpose of this study was to establish the nature of the interaction of endophytic fungi of wheat seeds with different levels of aggressiveness and presence in the mycobiota. Dual cultivation was carried out at potato-glucose agar (PGA), comparing with single fungal cultivation. The mutual influence of fungi during joint cultivation was established. Alternaria arborescens, which dominated in the mycobiota of wheat seeds from northeastern Ukraine, suppressed the development of only P enicillium. Nigrospora oryzae, Bipolaris sorokiniana, and Phoma developed faster than A. arborescens. Fusarium poae, and F. sporotrichioides competed for agar medium with N. oryzae. Known bioagents from wheat seeds showed unexpectedly low results. Trichothecium roseum formed a rejection zone during co-cultivation with F. graminearum. Trichoderma sp. Max18 (resistant to fludioxonil) on the 7th day inhibited the development of Penicillium, F. graminearum, and A. arborescens by 55, 48 and 26%, respectively. N. oryzae developed faster than the mycoparasitic fungus, but the latter began to parasitize it only from the 13th day.

Abstract

Tea mosquito bugs (TMB; Helopeltis bradyi, Hemiptera, Miridae) are a main pest in tea and cacao plantations worldwide. Pheromone-mediated mating disruption (MD) is a promising strategy to manage TMB populations. Experiments were conducted to evaluate the simultaneous effect of TMB female delayed mating (1, 3 and 5 days delayed mating) and pairing duration (1 day, 5 days, and entire lifespan) on several reproductive parameters. Results showed that female delayed mating obviously affected egg number, egg viability, and offspring number, but male delayed mating did not show such effects. Shortened pairing durations had a significant effect on egg viability and offspring number but not on egg number. Increased delayed mating and pairing duration negatively affected adult longevity. In general, we noted that TMB reproductive performance is vulnerable to delayed mating and shortened pairing durations, thus providing essential guidance for the implementation of MD strategies of TMB in the field.

Abstract

The world population is projected to reach 9.8 billion in 2050, and 11.2 billion in 2100 (United Nations) and people will need food, and decrease the farming land. Thus, the importance of Internet of Things (IoT) and Computer Science (CS) in plant disease management are increasing now-a-days. Mobile apps, remote sensing, spectral signature analysis, artificial neural networks (ANN), and deep learning monitors are commonly used in plant disease and pest management. IoT improves crop yield by fostering new farming methods along with the improvement of monitoring and management through cloud computing. In the quest for effective plant disease control, the future lies in cutting-edge technologies. The integration of IoT, artificial intelligence, and data analytics revolutionizes monitoring and diagnosis, enabling timely and precise interventions. Cloud computing facilitates real-time data sharing and analysis empower farmers to combat diseases with unprecedented efficiency. By harnessing these innovations, agriculture can embrace sustainable practices and safeguard crop health, ensuring a bountiful and secure future for the global food supply.

Abstract

The population dynamics of Tetranychus urticae (two-spotted spider mite – TSSM) are influenced by environmental factors, which were investigated to identify methods limiting the development and harmfulness of this pest. This paper presents findings from a laboratory study on the effect of spraying with water-based extracts of Mentha piperita and Tagetes patula plants on the growth rate of TSSM larvae and nymphs. The time required for the transformation of the larvae into protonymphs was longer for T. patula water- based extracts than extracts from M. piperita. Differences in the time of transformation from the nymphal stage to adult TSSM were also observed depending on the plant waterbased extracts, their concentration, and the host plant on which nymphs were developing. The use of 100 g ∙ l-1 French marigold extract was associated with longer transformation time of nymphs on discs of pea leaves than all tested concentrations of French marigold extract applied to sugar beet leaves. Ten percent of the extracts from peppermint plants had a stronger limiting effect on TSSM nymphs on pea leaves than on bean or sugar beet leaves.

Abstract

Lasiodiplodia theobromae and Pseudofusicoccum kimberleyense are pathogens causing trunk canker in Carya illioniensis and there are still no reports of effective forms of control. However, biological control is a promising measure. The objective of this work was to isolate, identify and evaluate the action of Trichoderma spp. in the in vitro control of L. theobromae and P. kimberleyense and to identify the compounds produced by the antagonist. Trichoderma spp. was identified by molecular technique and morphologically characterized. The antagonistic action of T. asperellum isolates (obtained from the rhizospheric soil, and of an isolate obtained from a commercial formulation) was evaluated by pairing cultures and volatile metabolites on L. theobromae and P. kimberleyense. Optimization of the cultivation method of T. asperellum was carried out and the compounds produced by the antagonist were identified by gas chromatography. Isolates obtained from the soil were identified as T. asperellum and decreased mycelial growth of L. theobromae and P. kimberleyense in the crop pairing test (48.98% S6 x Qt), as well as by volatile metabolites (29.85% SM21 x TR4). The cultivation conditions that generated the filtrates with the greatest antifungal action used 20 g · l –1 of corn maceration water, yeast extract 7.5 g · l –1, pH 5, agitation 100 rpm, sucrose 50 g · l –1, inoculum concentration 105 spores /ml. Among the identified compounds, some stood out for having bioactive action, such as pyran derivatives, celidoniol, deoxy, pentadecanoicacid, 2,3-dihydro-3,5-dihydroxy-6-methyl, propanoicacid, 1-methylethyl ester and 9-octadecenoic acid. The T. asperellum isolates showed potential for biocontrol in vitro, acting by different mechanisms.

Abstract

This study is aimed to report and analyze the modern plants use in the historical rural localities of Chernihiv Polesie (Ukraine). The research materials were collected in two stages. At the first stage the main useful of the local natural flora were identified. At the second stage a sociological survey of adult local inhabitants on the plants use was conducted. The main groups of useful plants of the historical localities were established. The modern use of plants was analyzed. It was found that most plants were used by the local inhabitants for their own needs. However, certain edible, fodder and techniacal plants are a source of income for the local inhabitants. In the historical localities of Chernihiv Polesie all the traditional for the region ways of using the natural flora plants have been preserved (but to varying degrees). The degree of modern use of plants is primarily determined by the peculiarities of the vegetation (in particular, the predominance of pine, mixed forests and floodplain meadows) and financial incentives. This primarily applies to Vaccinium myrtillus gathering and laying hay in for the own use and sale. The local inhabitants use the plant resources lesser than the existining resource potential.

Abstract

The article summarizes results of the studies of the Coastal Clean Index (CCI) on selected Polish beaches. In 2022, an attempt was made to estimate the amount of litter on the beach in Ustka. Debris on the beach was collected during a peak season in July and August. An attempt was also made to estimate the daily increase in garbage on the beach. The main part of the research was based on the quality and quantity of litter in beach sediments to the east and west of Ustka. Litter was divided according to a type of material, use, size and origin. The collected material was dominated by a plastic waste. The largest amount of marine litter was collected on the beach, on the eastern side of the Słupia River.

Abstract

Water quality is an important factor to determine a development of living organisms, including the presence of amphibians. It this article we compared the water quality of both, natural infield reservoirs in areas with intensive cultivation of cereals and the recently created reservoirs in the gravel pits in Central Pomerania, northern Poland. We tested all the physico-chemical properties that may impact species richness and reproductive success of amphibians. We observed that gravel ponds were better oxygenated, with higher pH and conductivity, and were less fertile in nutrients. In Pomerania, the water reservoirs in gravel pits had better breeding conditions than in-field ponds with higher total nitrogen and total phosphorus concentrations. There are many scientific papers identifying a negative role of sand and gravel mines, including a release of heavy metals from sediments, a high non-metalic minerals concentration, a destruction of native species of vegetation and occurrence of alien species. Therefore, we should be careful in assessing the role of newly emerging reservoirs in sand and gravel mines. The purpose of our research is to show that sand/gravel mines can be used to protect nature and that they can have also a positive impact. Few previous studies indicate that they may be a favorable place for creating new breeding sites for amphibians, which may ultimately help to preserve species in the face of environmental pollution and climate change.

Abstract

This paper presents details of 37 storm surges that occurred on the Polish southern Baltic Sea coast in the autumn/winter 2021–2022 season. They emerged during the passage of a larger number of low-pressure systems than usual from the SW-W direction over the Baltic Sea. Based on an assessment of meteorological and hydrological conditions during the storms, the relationship between the wind parameters, the sea level increase, and its maximum elevation was ascertained. The relationship between the sea level and the run-up elevation was ascertained. The elevation of the sea level and run-up on the onshore were compared with the beach height. Sections with a lower beach were affected by dune erosion already at a lower sea level. The dependence of dune erosion on the sea level elevation was presented. The value of the dune base retreat depended on the beach elevation and the sea level expressed by the onshore flow called run-up. The most significant erosion occurred during the storm Nadine with a sea level of 1.0–1.28 m AMSL. The average erosion varied between 1.0 and 4.5 m. The maximum erosion values reached 8–13 m.

Abstract

Basing on the analysis of 440 vegetation plots (relevés) a classification scheme of sand biotopes of Chernihiv Polesie (Northern Ukraine) of levels IV–VI was compiled. Biotopes, protected by the Resolution 4 of the Bern Convention and Annexes II and IV of the Habitat Directive, were identified. The comparative characteristics of biotopes and syntaxa of vegetation according to floristic classification were given. Characteristics of the represented biotopes were described. The biotopes R1Q, R1P, R1M (EUNIS, 2021) appeared to be the most represented for the sands of Northern Ukraine. Fourteen biotopes of Chernihiv Polesie sands, protected by Council Directive 92/43/EEC of 21 May 1992, were revealed.

Abstract

The paper was focused on the reconstruction of past-environmental conditions dynamics based on the geochemical characteristics of sediments filling kettle-hole located in the western part of the Kashubian Lakeland, North Poland). Stratigraphic variability of lithogeochemical constituents and a set of 13 elements (TOC, N, P, Na, Ca, Mg, K, Al, Fe, Mn, Cu, Ni, Zn) were applied for Holocene reconstruction of certain processes and conditions in the studied kettle-hole. The detailed geochemical analysis allowed us to identify 6 phases in its development: Masz-1 stage covering sedimentation of sedge-moss peat over melting dead ice at the turn of the Preboreal and Boreal periods; Masz-2 stage of the initial phase of lake development with deep-water sedimentation; Late Boreal and Atlantic stage Masz-3 related to sedimentation of lacustrine chalk; Subboreal stage Masz-4 representing the beginning of lake terrestrialization; Subatlantic stage Masz-5 of lowland bog, and Masz-6 stage covering final phase of peatland evolution due to human activity. Principle component analysis highlighted the importance of two major factors controlling the geochemical variability of the studied sediments. These are the varied origin of supplying water reflected in the sedimentation of organic-calcareous sediments (PC1), and oxidative-reduction conditions determined by water level fluctuations (PC2).
