“…The different specie’s pots were arranged into 5 groups with 3 replicates. L1 L2, L3, L4, and L5 groups ( Figure 4 ) of pots were irrigated with distilled water, 30% shoot extract, 60% shoot extract, 100% shoot extract, and herbicide solution (Metafin Super 28.6% WDG), respectively, after 60 days of sowing seeds in pots [ 47 ].…”

Weed infestation is a prime challenge coupled with lowering crop production owing to their competition with crop plants for available resources such as nutrients, water, space, moisture, and sunlight. Among weed control methods, the implementation of synthetic herbicides offers an instant solution for getting rid of weeds; however, they are a direct source of potential hazards for humans and generate resistance against synthetic weedicides, making them less effective. Allelopathy is something that happens in nature that can be used as a weed control method that increases crop yield and decreases dependency on synthetic chemicals. The mode of action of some phytochemicals corresponds to synthetic herbicides. Due to this feature, allelochemicals are used as bio-herbicides in weed management and prove more environmentally friendly than synthetic weedicides. The present investigation aims to assess the ultra-responses of A. tenuifolius and C. arvensis, while growing them in a pot experiment. Various levels of shoot extract (L2, L3, and L4) of T. portulacastrum along with the L1 (distilled water) and L5 (synthetic herbicide) were applied to the weeds. Results indicated that aqueous extracts of shoot of T. portulacastrum significantly (p ≤ 0.05) affect all the measured traits of weeds and their effects were concentration specific. All morphological parameters were suppressed due to biotic stress with an increase in free amino acids and calcium ions along with a decline in metaxylem cell area and cortical thickness in the root, while the vascular bundle area increased. The shoot extract intrusive with metabolisms corresponded with the synthetic herbicide. It is concluded that Trianthema shoot extract has a powerful phytotoxic impact on weeds (A. tenuifolius and C. arvensis) and can be used in bio-herbicide production.

Weeds are one of the key threats to the natural and agricultural fields. Weeds pose severe losses in agricultural yield by procuring nutrients and releasing secondary metabolites. Therefore, weed management is crucial for securing quantity and quality of yield. Various strategies that are most commonly employed to weed control are mechanical, physical, chemical, and cultural. However, the best method to eradicate weeds is a biological approach. The herbicidal potential of plants that can produce allelochemicals is considered a major source of biological control.In crops, weed control through allelopathy is a beneficial and environment-friendly alternativeto traditional herbicides.The object of this study is to explore the allelopathic impact of Trianthema portulacastrum against the growth of weeds (Asphodelus tenuifolius and Convolvulusarvensis and wheat(Triticum aestivum). The experimentwas performed in the petri-plates to explore the effect of various concentrations (30%, 60%, and 100%) of root and shoot of T. portulacastrum and herbicide (Metafin Super 28.6% WDG) along with control (distilled water)on the seed germination and growth of the weeds and wheat. To meet up the objectives, various parameters (such as seed germination, root length, shoot length, and seedling dry weight)of tested species were estimated. Our results revealed that water extracts of T. portulacastrum significantly reducedthe growth parameterspossibility due to interference with various growth metabolic processes. We conclude thatwater extract of root and shootof T. portulacastrumcould be safer and more beneficial to minimize the weeds competition in the wheat field.

“…One important factor of the highly competitive nature and broad ecological adaptability found in invasive species is allelopathy. Allelochemicals produced by invasive plants can inhibit the growth of competing vegetation by releasing phytotoxic allelochemicals through leaf extracts [6,7], volatile organic compounds [8], and root exudates [9], thereby providing a competitive advantage for the invader [9]. The novel weapon hypothesis (NWH), which was initially based on the study of diffuse knapweed (Centaurea diffusa Lam.)…”

Invasive species have competitive advantages over neighboring native species and decrease the biodiversity of the local community. The novel weapon hypothesis suggests that invasive plants affect local plants and suppress soil-borne pathogens by exuding allelochemicals to facilitate invasion. Therefore, the following study was designed by focusing on the extracts derived from certain parts of plants, and the impact of the collected root exudates of invasive plants on soil-borne pathogens has been documented, but there is still a need to identify its mechanisms. We conducted several experiments to test whether the alien invasive plant species Wedelia trilobata (L.) Hitchc. can suppress soil-borne pathogens through its root exudates. We also attempted to explain the inhibition mechanism of the root exudates on soil-borne pathogens. The results showed that the root exudates of W. trilobata significantly inhibited the growth and activities of soil-borne pathogens under sterile petri dish and sand cultures. Specifically, root exudates decreased the conidial germination, mycotoxin production, and hydrolytic enzyme (pectinase, cellulase, and amylase) activities of soil-borne pathogens in liquid culture, indicating the inhibition mechanism of root exudates of W. trilobata on soil-borne pathogens. Our results provided direct evidence that the root exudates of W. trilobata help it to spread by suppressing resident pathogens and promoting its invasion.
