“…The effect of allelopathic substances from weed leaves on peas was weaker than the effect of underground plant parts in variants with perennial weeds. Obviously, this is because the chemical composition of the leaves of most weed species includes organic acids and vitamins having a positive effect on seed germination and they mitigate the inhibition of crop growth by phytotoxic compounds (Georgieva et al, 2021;Zareen et al, 2022).…”

“…Early adaptative nature, rapid growth, and fast spread of weeds make them able to inhibit growth of desired crops and reduce the final estimated yields. (Morderer et al, 2018;Shah et al, 2022;Zareen et al, 2022). Weeds that invade crops contest for environmental resources alongside releasing certain chemicals into the soil, thereby lowering yield potential (Lalbiakdika et al, 2022).…”

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.

“…An increase in weeds during agricultural production can trigger yield losses in crops and can depend on the type of weeds, crops, climate, weed density, weed emergence time, and others [ 4 ]. Additionally, these weeds might release a type of chemical substance called an allelopathic substance, which could negatively affect crops [ 5 ]. Despite the reduction management of weeds being a focus during the employment of synthetic herbicide, serious damage to the environment is produced due to its negative effects which include the acceleration of soil erosion, herbicide-resistant weeds, and contamination in vegetables and/or foods [ 2 ].…”

Petroselinum crispum (Mill) Fuss is an aromatic plant belonging to the Apiaceae family and used in gastronomy as a spice. Several studies have been developed in leaves but studies are limited in seeds, especially the essential oils obtained from seeds. The aim of this study was to determine the phytochemical profile of the volatile compounds of this essential oil by gas-chromatography–mass spectrometry (GC-MS) in order to evaluate its phytotoxic activity on Lactuca sativa seeds and to carry out an in silico analysis on the target enzyme of the herbicide glyphosate 5-enolpyruvylshikimate 3-phosphate synthase (EPSP). The essential oil was obtained by steam distillation for two hours and then was injected into a GC-MS, the phytotoxic assay was carried out on Lactuca seeds and the in silico evaluation on the EPSP synthase focused on the volatile compounds similar to glyphosate, docking analysis, and molecular dynamics to establish the protein–ligand stability of the most active molecule. The chromatographic analysis revealed 47 compounds, predominated by three compounds with the most abundant percentage in the total content (1,3,8-ρ-menthatriene (22.59%); apiole (22.41%); and β-phellandrene (15.02%)). The phytotoxic activity demonstrated that the essential oil had a high activity at 5% against L. sativa seed germination, inhibition of root length, and hypocotyl length, which is comparable to 2% glyphosate. The molecular docking on EPSP synthase revealed that trans-p-menth-6-en-2,8-diol had a high affinity with the enzyme EPSP synthase and a better stability during the molecular dynamic. According to the results, the essential oil of P. crispum seeds presented a phytotoxic activity and might be useful as a bioherbicide agent against weeds.

“…The presence of weeds in cultivated plants causes a decrease in the quality and quantity of crop yields. Weeds reduce crop yields directly through competition for nutrients and allelopathy, thereby inhibiting plant development (Jabran et al, 2015;Zareen et al, 2022). Weed control is mostly done by mechanical means and the use of synthetic chemical herbicides.…”

Weed pathogenic fungi play an important role in biological control of weeds. Weeds grow a lot among cultivated plants, the role of weed pathogenic fungi to cultivated plants is not yet known. This research aimed to determine the effect of weed pathogenic fungi on bok choy. The research was carried out in Tambaksogra Village, Sumbang District, Banyumas Regency at an altitude of 100 m above sea level. Randomized block design was used with treatments of weed pathogenic fungi (Fusarium sp., Curvularia sp., Chaetomium sp., Fusarium sp. + Curvularia sp., Fusarium sp. + Chaetomium sp., Curvularia sp. + Chaetomium sp., and Fusarium sp. + Curvularia sp. + Chaetomium sp.) repeated four times. The observed variables included symptoms, incubation period, disease intensity, disease incidence, infection rate, AUDPC, number of leaves, plant height, and plant fresh and dry weight. Results showed that Curvularia sp., Chaetomium sp., and Curvularia sp. + Chaetomium sp. did not affect on bok choy, while Fusarium sp., Fusarium sp. + Curvularia sp., Fusarium sp. + Chaetomium sp., and Fusarium sp. x Curvularia sp. + Chaetomium sp. caused disease intensity of 2.7, 2.7, 3.55, and 4.4%, respectively, and affected plant dry weight by 113.35, 82.36, 77, and 74.07 %, respectively, from control. Curvularia sp., Chaetomium sp., and Curvularia sp. + Chaetomium sp. could be used as a bioherbicide in bok choy cultivation.
