Lactic acid bacteria (LAB) are found on the surface of some plants, forming their natural microbiome, and especially common in fermented plant products. They microorganisms capable performing lactic fermentation, during which they utilize carbohydrates produce acid. considered probiotic microorganisms. LAB characterized by strong antagonistic activity against other The mechanism action these is mainly based production substances with antimicrobial activity. Some strains also inhibit...

Abstract Vascular wilt diseases caused by Verticillium dahliae Kleb. are difficult to control and lead increasing losses of many crops worldwide. It can cause disease on not only horticultural but also economically important such vegetables, legumes, forest trees, woody herbaceous plants. Reasons this situation various: (i) the specialization crop production resulted in accumulation pathogen soil, especially monoculture production; (ii) lack an efficient safe soil fumigation method; (iii)...

Abstract Agricultural fungicide pollution poses a significant environmental challenge and causes adverse effects on human health. Therefore, strategies to limit usage are of paramount importance. Trichoderma fungi, due their antagonistic activity against various pathogenic have shown potential as sustainable alternative chemical fungicides. However, bio‐control agents like vulnerable physical stimuli show diminished efficacy during prolonged storage. To address these challenges, mild...

The potential use of volatile compounds released from milled seeds mustard (Brassica juncea cv. Malopolska) obtained three different companies was tested in vitro and vivo experiments for their inhibitory effect on Botrytis cinerea growth agar media its infection vegetable leaves cucumber, bean spinach. In the with spinach, volatiles mustards storage sensory quality fumigated evaluated. antifungal depended source dosage biofumigation time. most efficient inhibition B. mycelium S SHR company....

Root-knot nematodes Meloidogyne spp. are sedentary endoparasites that infest a wide range of plant species; they also widely distributed, making them one the most economically significant pests. Similarly, damage caused by Aphelenchoides fragariae can lead to substantial reductions in both crop yield and quality. This research focused on rhizosphere Helianthus tuberosus L. (variety Albik), grown Polish plantation. The experiment was conducted at National Institute Horticultural Research...

The investigation is devoted to the analysis of impact organic fertilisers, in particular biochar derived from sewage sludge, on productivity energy crop Miscanthus × giganteus and soil health marginal lands. results long-term observations show that among additives, demonstrates most pronounced stabilising effect structure nematode community, although its total number nematodes limited. application increased diversity trophic groups modified network, which was dose-dependent. experiment also...

The aim of the study was to determine presence and concentration indicator microorganisms on leafy green vegetables available in Poland.Microbial analyses 122 samples vegetables: rocket, lamb's lettuce, iceberg chive, spinach, celery, dill parsley, sold Polish supermarkets 2018 2019, were conducted. analyzed for aerobic mesophilic bacteria, yeasts moulds, Enterobacteriaceae, Enterococcus, coliforms Escherichia coli number according standards.The most microbiologically contaminated occurred...

The evaluation of the potentiality lactic acid bacteria (LAB) strains isolated from fermented products to inhibit Botrytis cinerea and Escherichia coli O157:H7 growth on spinach lettuce was conducted. From a total forty LAB tested, three were selected due their high inhibitory effect plant pathogenic fungi. identification these isolates based 16S rRNA gene fragment sequence analysis confirmed genus Levilactobacillus sp. Lactiplantibacillus An effective method coating surface developed....

Abstract Sclerotinia sclerotiorum (Lib.) de Bary is considered as one of the most harmful soilborne pathogens, which reduces productivity horticultural crops. Currently used chemical or biological methods for eradication S. from a soil are not very effective. The aim this study was to evaluate possibility sclerotia using Trichoderma isolates, were multiplied on organic carriers prepared agro-industrial wastes and by-products: WsA (wheat straw + apple pomaces), WsP potato pulp) T-GRAN (dry...

The aim of this study was to develop ready-to-eat vegetable–herb mixes with high nutritional and sensory values as well good storability. In regard, the suitability fresh herbs (peppermint, oregano, green basil, red parsley) tested for their use in fresh-cut iceberg lettuce. Lettuce–herb mixtures were stored 6 days at 5 °C. reason decrease appearance salads browning cut surface lettuce, discoloration on herbs. Comparing storage abilities herbs, basil parsley retained best d A small addition...

Abstract The effect of granulated organic waste material overgrown with Trichoderma atroviride TRS25 on the survival Sclerotinia sclerotiorum and Chalara thielavioides in soil was investigated. Application this into at a dosage 1% (w/v) reduced S. sclerotia to almost zero after 2 months incubation. were parasitized by T. fungus multiplied granulates. detrimental granulates Ch. observed 4 granulates, without fungus, caused decrease pathogen population soil. introduced as conidia suspension...

The Effect of Selected Plant Materials and Extracts on the Development Bacterial Diseases Onion effects Brassicaceae Solanaceae plant residues water extracts from these growth onion ( Allium cepa L.) pathogenic bacteria Pectobacterium carotovorum subsp. carotovorum, Burkholderia cepacia gladioli pv. alliicola were examined. influence materials development bacterial diseases bulbs was also investigated. toxic effect depended kind amount agent used species examined bacteria. extract Brassica...

Specific bacterial disease symptoms were observed on onion bulbs in almost all regions Poland. For the purpose of identification agents causing disease, bacteria isolated from symptomatic plants. Their pathogenicity was confirmed by using test scales. These identified biochemically and molecularly as Serratia plymuthica.

Agricultural fungicide pollution poses a significant environmental challenge and carries adverse consequences for human health. Therefore, strategies to limit usage have gained paramount importance. Trichoderma fungi, owing their antagonistic activity against various pathogenic emerged as prospective candidates enhancing both the effectiveness sustainability of plant protection. Nevertheless, utilization bio-control agents like has unveiled new challenges, notably vulnerability physical...

Abstract The Brassica genotypes selected for the experiments were previously found to be resistant various Plasmodiophora brassicae pathotypes (Pb). Their interaction with Pb2, Pb3 and Pb9 isolated in Poland was studied, using macroscopic observation presence of root galls, microscopic observations P. plasmodia hairs quantitative PCR determination pathogen’s quantity plant roots growing media. Of only B. rapa var. capitata line AABBcc fully all Polish brassicae. Some other...

Abstract In recent years, the use of bio-fertilizers enriched with specially selected microorganisms has been used more and often. The beneficial effects consortia on strawberry plants have reported previously. purpose research was to determine effect containing fungal bacterial strains living in rhizosphere plants. experiments described this paper, synthetic mineral fertilizers were microorganisms. fertilizer urea fungi Aspergillus niger Purpureocillium lilacinum , while Polifoska 6 Super...

The Effectivity of Trichoderma Strains in the Protection Cucumber and Lettuce Against Rhizoctonia Solani Antagonistic properties four isolates against fungal pathogen solani were investigated. addition T. harzianum strain PBG to potground protected cucumber plants root rot caused by R. increased weight growing with 19-26%, compared infested control. All strains ( PBG; longibrachiatum szczep T2; T4 sp. T6) indicated positive effect on lettuce growth greenhouse experiment. They number...
