Herbicidal Potential of Some Dry Land Plants Against Lathyrus aphaca (L.), Winter Season Weed

Abstract

Dry land plants owing to their capability to grow under stressful environment have shown higher allelopathic potential as compared to cultivated plants. An experiment was conducted to investigate the herbicidal potential of aqueous extracts of four dry land plants viz. fruit and vine of Citrullus colocynthis, and above ground parts of Rhazya stricta; Crotalaria burhia and Calligonum polygonoides, with four concentrations (25, 50, 75 and 100%) of initially prepared extracts against Lathyrus aphaca, a common weed of wheat in the studied region. These plants were collected from dry land area (30.03° N and 70.38° E, 129 m above sea level, almost desert conditions) of Dera Ghazi Khan, Punjab, Pakistan. All the four plants exhibited pronounced herbicidal potential with 9 to 91% suppression of different parameters in L. aphaca). Maximum inhibition was recorded in germination (36-91%). Significant suppression in leaf count (9-65%), shoot length (12-59%), root length (4-62%), shoot fresh weight (17-71%), root fresh weight (10-60%), shoot dry weight (15-72%), root dry weight (13-64%), and nodule numbers (34-89%) was also observed. The highest inhibition was exhibited by R. stricta followed by C. colocynthis: fruit. However, in case of nodulation maximum suppression was produced by C. burhia extract. Least suppressant activity was observed for the C. polygonides extract. These results encourage the potential use of locally available dry land plants possessing strong allelochemical properties for nonchemical control of weeds ultimately reducing reliance on chemical control.

The Bio-herbicidal potential of some wild plants with allelopathic effects from Tabuk Region on selected local weed species

“…No root elongation was observed at 35 and 50 g/L of Citrullus colocynthis. Also, in accordance with our results, Iqbal et al (2020) examine the herbicidal potential of aqueous extracts of Citrullus colocynthis fruit and vine at four concentrations (25, 50, 75, and 100%) against Lathyrus aphaca, a prevalent weed of wheat in the area under study. They mentioned that fruits and vines demonstrated strong herbicidal potential, suppressing several L. aphaca characteristics such as reduction in the number of leaves, shoot length, root length, shoot weight, root fresh weight, shoot dry weight, root dry weight, and nodule numbers.…”

“…Additionally, the inhibition of the shoot growth of Amaranthus retroflexus was observed at 35 and 50 g/L of Citrullus colocynthis. Also, Iqbal et al (2020) found that Citrullus colocynthis fruit and vine extracts at four concentrations (25, 50, 75, and 100%) had a strong effect in minimizing the growth of Lathyrus aphaca. They mentioned that fruits and vines demonstrated strong herbicidal potential, suppressing many of leaves, shoot length, root length, shoot fresh weight, root fresh weight, shoot dry weight, root dry weight, and nodule numbers.…”

Antifungal and Antibacterial Activity of <em>Lathyrus Aphaca L.</em> Mediated Green Synthesized CdS Nanoparticles and their Characterization

“…Based on the results of the experiment, it was determined that both substances had an allelopathic effect on the development of shoots from Zea mays seeds. Alkaloids, triterpenes, glycosides, tannins, and the volatile bases have all been found in the leaves of Lathyrus Aphaca L. specie [15].…”

Allelopatic effects of Waltheria indica L.: Biocontrol potential in ecological restoration

“…Allelopathy is the process in which a plant produces chemical substances (allelochemicals) that can interfere with the growth and establishment of other plants (Lovett & Ryuntyu, 1992;Li et al, 2011). In this context, biological control by allelopathy, can be an alternative in the control of exotic invasive species, favoring ecological restoration (Lopes, 2017;Iqbal et al, 2020). Allelochemical substances can bring an ecological and sustainable alternative for the control of exotic and invasive species such as bioherbicides (Rosa et al, 2007;Rigon et al, 2013).…”
