“…Further, all the treatments, especially combined exudates, caused a reduction in root growth (root length and biomass), indicating root inhibition ( Figure 2 ), whereas Bromus sterilis exhibited an increased root growth under all the treatments, which once again suggests the potential hormesis. Other studies also found differential root growth effects of allelopathy contingent upon the invader species [ 78 ]. Varying shoot and root growth responses of Veronica persica and Bromus sterilis reveal the different allelochemical sensitivities of these invasive species.…”

Root exudates of the invasive Solidago canadensis and the cereal crop Sorghum bicolor (L.) Moench cv. ‘Hybridsorgo’ were tested for allelopathic interactions against native and invasive plant species in a controlled environment. After the surface was sterilized, the seeds of two invasive species (Bromus sterilis and Veronica persica) and two native species (Youngia japonica and Rumex acetosa) were germinated and transplanted into the soil (1:1 mixture of coco peat and sand) that had been conditioned for one month by the cultivation of Solidago canadensis and Sorghum bicolor, both in combination or as unplanted controls. After an additional eight weeks of growth, morphometric measurements of the shoot and root, including foliar characteristics and above- and below-ground biomass accumulation, were performed. The results revealed significant inhibitory effects of root exudates released by Sorghum bicolor and Solidago canadensis on native species’ productivity and physiology. The invasive species exhibited variable growth responses, with Veronica persica showing reduced shoot and root expansion, but Bromus sterilis revealed increased shoot and root biomass allocation and nutrition under the exudate treatments. Exudates from Solidago canadensis and Sorghum bicolor together showed synergistic negative effects on native species, while they promoted growth and nutrition in Veronica persica. Taken together, the differential species responses indicate that the tested native species were more sensitive to the allelopathic compounds than the invasive species, which is in line with the theory of novel weapons. The legacy effects of root exudates of both Sorghum bicolor and Solidago canadensis could promote invasive establishment through imposing allelochemical interference competition against native plant species. Understanding the specific allelopathic mechanisms may help with the development of integrated strategies for managing invasive species.

“…Previous studies indicated that these compounds were also present in concentrated extracts of other Artemisia spp. [15] and in different solvent extracts of Artemisia dubia [5,16]. The presence of these secondary metabolites as bioactive components that were identified during the qualitative phytochemical tests may be responsible for the molluscicidal activity of wormwood EE.…”

Material and methods Collection of wormwood leavesThe plants were collected from Barangay Gabas, Baybay City, Leyte, Philippines during the growth stage between in April and May and were identified by a botanist, Dr. Beatriz S. Belonias of the Department of Biological Sciences, College of Arts and Sciences, Visayas State University. The identification of plants was based on morphological keys as formerly described by previous studies [6,7]. The dirt and debris from the leaves were washed with running tap water. After washing, the leaves were air-dried at room temperature for 3 days [8]. Dried leaves were chopped finely into manageable pieces, ground finely, and airdried again at room temperature for 7 days to remove the remaining moisture content of the leaves [9]. Extraction of bioactive compoundsGround dried leaves were completely submerged with ethanol for infusion for 48 h. After infusion, the preparation was filtered using a funnel topped with filter paper. The filtrate was placed in a beaker and the plant leaf residue was discarded. The filtrate was concentrated in a rotary evaporator at 40 °C and recovered 1/3 of its original volume. The recovered concentrated extract of wormwood

“…The biological activity of plants with allelochemicals depends on the concentration. Characteristic responses include stimulation at low concentrations of allelochemicals but inhibition as concentrations increase [33]. Therefore, it is concluded that its bio-stimulant effect on crops and herbicidal effect on weeds can make it an ideal solution in an integrated crop protection program.…”

The Green Deal strategy has the very ambitious goal of transforming the European Union into the first climate-neutral continent by 2050. For the agricultural sector, one of the main challenges is to reduce the use of synthetic fertilizers and pesticides. Crop protection measures aim to maintain and ensure certain standards of yield and quality, which are generally achieved by the control of pests, diseases, and weeds. One of the possibilities to reduce the use of pesticides could be allelopathic plants, which are not only potential sources of allelochemicals but also renewable biomass sources. The aim of this study was to analyze the productivity of Artemisia dubia Wall and evaluate the allelopathic effects of biomass on crops and weeds. It was determined that the biomass productivity of A. dubia varied from 2 to 18 t ha−1, depending on how many times it is cut during the growing season and the fertilizer rate. A. dubia has allelopathic properties, which were verified using an aqueous extract and can completely suppress the germination of Taraxacum officinale seeds. Young plants harvested in the middle of summer were characterized by the highest number of phenolic compounds. This shows the strong allelopathic effect of A. dubia biomass on other plants.
