“…Allopathic substances from weeds can have inhibitory effects on the seed germination of other weed species. Therefore, they can be used as bioherbicides (Kostina-Bednarz et al, 2023) or for improving the phytosanitary state of agrophytocenoses (Erez & Battal, 2022). It should be noted that different varieties of crop plants may have a different reaction to phytotoxic weed extracts.…”

Segetal vegetation should be controlled both during crop growing season and after harvesting. The reason is that undesirable vegetation accumulates a significant mass, one that will later become a threat to the following crop in crop rotation. Mixtures of substances of biogenic origin, called allopathic, are constantly changing subject to abiotic factors and environmental conditions. Therefore, their effects on organisms are characterized by significant variability. According to the biotesting results, we found that allopathically active substances of all experimental weed species had a negative effect on pea seed germination. In the control variant, all seeds germinated in 4 days, but in some experimental variants 2–3% of the seeds were in the phase of swelling. Water extracts from different species and parts of weeds had significant inhibitory effect on the germination of pea seeds and further growth. The water-soluble extracts from the underground organs of perennial weeds such as Elytrigia repens L. and Cirsium arvense L. were particularly strong, leading to 58.2% and 53.1% reduction in the length of the embryonic root. Water-soluble extracts from the leaves of these weeds had slightly lower effects on pea germination, and the lags in root growth were 33.5% and 31.4%, respectively. Extracts from weed stems also inhibited pea germination and had an intermediate effect between the effect of water-soluble extracts from the underground part and leaf blades. The effect of extracts from roots of annual weeds on the length of the germinal root ranged 36.6% in common stork’s-bill (Erodium cicutarium L.) to 13.9% in chickweed (Stellaria media L.). The allopathic effect of the substances from the leaves of chickweed (Stellaria media L.) and potato weed (Galinsoga parviflora Cav.) had the lowest effect on the growth of pea root. The lag of the indicator in the control was 7.2% and 12.9% for the variants.

“…Naturally grown plants contain compounds that possess potential biological effects, with these components being produced in greater quantities under stressful conditions and released into the environment. Secondary metabolites, in particular, have been linked to allelopathy and have been the focus of research in various elds, including differentologists, herbologists, ecologists, and physiologists (Li et al, 2020;Erez and Battal, 2022). These secondary compounds, which are also involved in allelopathy, are referred to as allelochemicals.…”

This study aims to investigate the composition of essential oils, antioxidant activity, total phenolic and flavonoid content, as well as antifungal and herbicidal activities of the methanol extract of Vaccinium myrtillus collected from two different locations. Using GC/MS analysis, the plant essential oils from Muğla and Mersin locations were found to contain 20 and 19 components, respectively. The main components identified in the essential oils from Muğla and Mersin were α-Pinene (29.16%-15.75%), Eucalyptol (22.19%-26.46%), and Linalool(12.66%-25.27%). The methanol extracts of plant collected from two different areas were tested for antifungal activity against Sclerotinia sclerotiorum (SS), Fusarium oxysporum f sp. melonis (FOM), Fusarium oxysporum f sp. cucumerinum (FOC), and Rhizoctonia solani (RS). At a dose of 3000 ppm, the extracts inhibited mycelium growth by 78.00%, 73.31%, 46.33%, and 31.43% for SS, FOM, FOC, and RS, respectively. In allelopathy tests, the methanol extract of blueberry at a dose of 3000 ppm completely suppressed root-shoot development of Taraxacum officinale, while it significantly inhibited root-shoot development of Rumex crispus seed germination compared to the control. In addition, the plant exhibited significant antioxidant activity.These findings are significant as they provide insights for the development of new natural antifungal agents with potential applications in agriculture.
