“…It is noteworthy that pyrethrum extract affected growth of lettuce seedlings (Fig. 3), and there are previous reports about allelopathic effects of plant raw material (Ali et al, 2019) including chrysanthemum extract (Kil and Lee 1987;Beninger and Hall 2005;Salim and Abdalbaki 2017). The results of our study and previous report show that this screening method also can be applied to screen candidate materials for weed control.…”

Strategic utilization of organic material for agriculture is important for improve efficiency in organic agriculture. Waste from food processing is a good candidate for compost material, and the first critical step is to choose proper raw material. In this study, we tried to establish a reliable screening method by comparing growth of different plant parts in different crops in combination with serial dilution of raw material extracts. The raw materials compared here are tangerine pomace, herbal medicinal plant waste, bread, spent coffee ground (SCG). We also compared effect of organic fertilizer made of SCG, natural pesticides made of pyrethrum extract and neem oil. The results obtained from different kind of crops and plant parts give insight into growth enhancing or inhibitory effect of tested material which will be useful screening raw material to make organic fertilizer and crop protective materials.

“…Medicinal applications of Boerhavia procumbens include diaphoretic, diuretic, expectorant, emetic, laxative, stomachic, rejuvenates and purgative (Khalil et al, 2017;Wajid et al, 2017;Khan et al, 2020). It is mentioned to be effective against cardiac disorders, asthma, hemorrhoids, edema, eye diseases, insomnia, jaundice, kidney stone, nervous system related disorders, cough, against snake venom, urethritis, skin related diseases, intestinal, anemia, and colic kidney disorders (Hussain et al, 2012;Ali et al, 2019).…”

The goals of the present study were to use silver nitrate (AgNO 3 ) solution to synthesize plant-mediated silver nanoparticles (AgNPs) using Boerhavia procumbens extract, to evaluate the antimicrobial potential of crude B. procumbens extracts as well as the antimicrobial potential of synthesized AgNPs. The antimicrobial activity was tested against ten pathogenic bacterial strains including Klebsiella pneumonia, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Citrobacter braakii, Providentia spp., Salmonella typhi, Salmonella para typhi, Vibrio cholera, and Proteus vulgaris and seven fungal species; Rhizopus stolonifer, Candida albican, Alternaria alternata, Aspergillus flavus, Verticillium chlamydosporium, Penicillium chrysogenum, and Aspergillus oryzae. The methanol extract was fractionated using several solvents and subjected to phytochemical analysis along with FTIR. Phytochemical analyses revealed flavonoids, tannins, saponins, steroids, quinones, and phenols in the crude plant extract. AgNPs were synthesized using B. percumbens extract and characterized by UV-Vis, Fourier-transform infrared spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). Synthesized AgNPs were spherical, with 20-80 nm diameter. The absorption peak of synthesized AgNPs was observed at 392 nm. AgNPs have significant antimicrobial potential against selected pathogenic bacterial and fungal species as compared to different fractions of crude B. procumbens extract. The current study suggests that green synthesis is a useful technique and can be used as an alternative to antimicrobial agents against pathogenic organisms.

“…Morikawa et al (2012) had screened 170 plant species in Peru using sandwich method and found that 50 mg of leaf debris from Aristeguieta ballii, Diplostephium foliosissimum and Spondias mombin resulted in 90% inhibition of root and shoot growth of lettuce seedlings. Similarly, Ali et al (2019) found that the radicle growth of lettuce seedlings were inhibited when treated with 50 mg of leaf debris of 196 medicinal plants species in Pakistan. From this study, it can be concluded that the leaf litter leachate of P. foetida showed the highest allelopathic effect among 100 weed species tested.…”

Aim: This research was conducted to assess the allelopathic potential of 100 plants species, including noxious weeds and medicinal plants of Malaysia as donor plant on the growth of Lactuca sativa (lettuce) as the recipient plant. This study was also carried out to justify common weeds found in Malaysia to act as a natural herbicide for weed management through allelopathy phenomenon. Methodology: Weed and medicinal plant species commonly found in Malaysia were identified according to their morphological characteristics. Sandwich method was carried out to determine the allelopathic potential of weed species through leaf litter leachate mechanism. On the other hand, dish pack method was conducted to discover the allelopathic potential of weed species through volatilization pathway. Results: 100 weed species and medicinal plants commonly found in Malaysia inhibited the radicle and hypocotyl growth of L. sativa by both sandwich method and dish pack method. Among 100 weed species, Passiflora foetida showed the maximum inhibitory effects on L. sativa growth in both sandwich and dish pack method. The highest amount of P. foetida leaf litter (50 mg), completely inhibited the growth of radicle and hypocotyl of L. sativa. Volatilization of weed and medicinal plants leaf litter inhibited the growth of L. sativa with increasing distances of lettuce seed with the weed and medicinal plants leaf litter. Interpretation: The findings of this study provides a base line for identifying plants with allelopathic properties for controlling weed propagation.
