“…Furthermore, when compared to germination percentage and the coleoptile length, the radicle length of the test species was more sensitive to extracts. As radicles are the first organ to be exposed to phytochemicals and have more permeable tissue than other organs [ 21 , 26 , 27 ], and/or low mitotic division in the root apical meristem [ 28 ], radicle growth is more sensitive to allelopathic plant extract. Furthermore, phytochemicals can inhibit the development of radicle tissues and endoderm by affecting genes involved in cellular characterization [ 29 ].…”

“…At the mature stage of C. iria , the maximum concentration (100 g L −1 ) of P. hysterophorus extract resulted in the greatest decrease. Many researchers from all around the world have demonstrated dose-dependent inhibitory activity [ 21 , 27 , 30 , 31 ]. Only untreated C. iria continued flowering 21 days after spray, indicating that allelochemicals stress may have suppressed the other treated plants.…”

“…Bioassays are generally designed to test the allelopathic properties of a plant species. However, a plant that shows strong phytotoxicity on the target plant species in laboratory conditions might not be so strong in the field condition due to the influence of several environmental factors [ 20 , 21 ]. In this context, two experiments were conducted in both laboratory and glasshouse conditions to evaluate the allelopathic properties of P. hysterophorus with a view to developing natural-product-based bioherbicides.…”

The allelopathic effect of various concentrations (0, 6.25, 12.5, 50 and 100 g L−1) of Parthenium hysterophorus methanol extract on Cyperus iria was investigated under laboratory and glasshouse conditions. No seed germination was recorded in the laboratory when P. hysterophorus extract was applied at 50 g L−1. In the glasshouse, C. iria was mostly injured by P. hysterophorus extract at 100 g L−1. The phytochemical constituents of the methanol extract of P. hysterophorus were analyzed by LC-ESI-QTOF-MS=MS. The results indicated the presence of phenolic compounds, terpenoids, alkaloids, amino acids, fatty acids, piperazines, benzofuran, indole, amines, azoles, sulfonic acid and other unknown compounds in P. hysterophorus methanol extract. A comparative study was also conducted between P. hysterophorus extract (20, 40 and 80 g L−1) with a synthetic herbicide (glyphosate and glufosinate ammonium at 2 L ha−1) as a positive control and no treatment (negative control) on Ageratumconyzoides, Oryzasativa and C. iria. The growth and biomass of test weeds were remarkably inhibited by P. hysterophorus extract. Nevertheless, no significant difference was obtained when P. hysterophorus extract (80 g L−1) and synthetic herbicides (glyphosate and glufosinate ammonium) were applied on A.conyzoides.

“…Additionally, bioassay performance may help the researchers to predict the allelopathic potentials of a plant in glasshouse or field conditions [18]. However, a plant that showed strong allelopathic activity on target plants in s laboratory bioassay, might differ in glasshouse or field conditions due to the influence of several environmental determinants [19]. Plant crude extract with strong allelopathic potential has recently contributed greatly to weed management and controlling weeds [19][20][21][22].…”

Natural product-based herbicides could be the effective alternatives to synthetic chemical herbicides for eco-friendly weed management. This research, therefore, was conducted to identify the phytotoxic properties of Parthenium hysterophorus L., Cleome rutidosperma DC. and Borreria alata (Aubl.) DC. with a view to introducing them as a tool for natural herbicide development. The methanol extracts of these plants were examined on the germination and growth of Zea mays L., Oryza sativa L., Abelmoschus esculentus (L.) Moench and Amaranthus gangeticus L., Oryza sativa f. Spontanea Roshev. (Weedy rice), Echinochloa colona (L.) Link., Euphorbia hirta L., and Ageratum conyzoides L. under laboratory and glasshouse conditions. A complete randomized design (CRD) with five replications and randomized complete block design (RCBD) with four replications were laid out for laboratory and glasshouse experiments, respectively. In the laboratory experiment, three plant extracts of 0, 6.25, 12.5, 50, and 100 g L−1 were tested on survival rate, hypocotyl, and radicle length of eight test plant species. No seed germination of A. conzyoides, E. hirta, and A. gangeticus were recorded when P. hysterophorus extract was applied at 50 g L−1. C. rutidosperma had the same effect on those plants at 100 g L−1. In the glasshouse, similar extracts and concentrations used in thelaboratory experiments were sprayed on at the 2–3 leaf stage for grasses and 4–6 for the broadleaf species. Tested plants were less sensitive to C. rutidosperma and B. alata compared to P. hysterophorus extract. Among the weeds and crops, A. conyzoides, E. hirta, A. esculentus and A. gangeticus were mostly inhibited by P. hysterophorus extract at 100 g L−1. Based on these results, P. hysterophorus was the most phytotoxic among the tested plant extracts and could be used for developing a new natural herbicide for green agriculture.

Herbicides made from natural molecules may be a good environmentally friendly alternative to synthetic chemical herbicides for weed control. As a result, this investigation was carried out to ascertain the phytotoxicity of Parthenium hysterophorus L. as well as to identify its phenolic components. Germination of seeds and devel-opment of seedlings of Vigna subterranea (L.) Verdc, Raphanus sativus (L.) Domin, Cucurbita maxima Duchesne., Cucumis sativus L., Solanum lycopersicum L., Capsicum frutescens L., Zea mays L., Abelmoschus esculentus (L.) Moench, Daucus carota L., Digitaria sanguinalis (L.) Scop and Eleusine indica (L.) Gaertn were investigated using P. hyster-ophorus leaf, stem, and flower methanol extracts. Six concentrations (25, 50, 75, 100, and 150 g L-1) were com-parison to the control (distilled water). The concentration of extracts increased, the rate of the seed sprouting and seedling growth decreased. EC50 values showed that the extraction of leaf of P. hysterophorus (811) was phytotoxic in comparison to the stem (1554) and flower (1109) extract. According to PCA analysis, Raphanus sativus, Solanum lycopersicum, Capsicum frutescens, Abelmoschus esculentus, Daucus carota, Digitaria sanguinalis, and Eleusine indica were all very susceptible to allelochemicals. LC-MS analysis revealed that the P. hysterophorus leaf extract contained 7 phenolic compounds that were responsible for inhibition. These studies also revealed that the leaf of P. hysterophorus is a major source of phytotoxicity, which could be valuable in the future for developing a natural herbicide.
