“…Plant allelopathy has been considered as a herbicide reduction and a labor-saving weed management strategy (compared to hand weeding) in agricultural production systems [ 12 , 13 ]. Viji and Chinnamuthu [ 14 , 15 ] pointed out that the CR tuber dormancy could be induced by phenolics such as vanillic acid. Babu and Kandasamy [ 16 ] found that the tuber sprouting percentage of CR could be inhibited significantly by a water extract of fresh leaves of Eucalyptus globulus Labill.…”

Bidens pilosa L. var. radiata Sch. Bip. (BPr) had been found capable of excluding Cyperus rotundus L. (CR) from its vegetation in fallow fields. Both allelopathy and competition of BPr were able to limit the growth of CR, but this has not been extensively investigated. To verify the two effects of BPr on CR management, density-dependent experiments and interspecies competitions with the application of activated carbon were conducted. The effects of BPr soil and its residues on the reproduction of CR were also evaluated. The results showed that the residues of BPr reduced the growth (54–61% of control) and tuber number (58–71% of control) of CR in the 3 plants pot−1 treatment but not in higher density treatments. In the interspecies competition, BPr exhibited an allelopathic but not competitive effect on CR when activated carbon was absent. CR tuber sprouting was significantly suppressed when sowed in the BPr soil. Likewise, BPr residue mulch inhibited the CR plant density by 87% as compared to natural-occurring CR residue mulch in the field. This study revealed that BPr might have potential for use as a cover plant and allelopathic mulch to control CR in the agroecosystem.

“…Eliminating naturally occurring germination inhibitors in some weeds also improves germination. For instance, due to the breakdown of phenols and other germination-inhibiting biochemical components, the germination of purple nutsedge (Cyperus rotundus L.) tubers is improved when treated with nanoparticles of iron oxide [34] and zinc oxide [35]. When the glycolysis process is inhibited by herbicide-encapsulated nanoparticles, which includes silver nanoparticles in purple nutsedge (Cyperus rotundus L.), they target the receptors of weed roots and starve them by lowering their food supply.…”

The number of effective herbicides available to farmers is steadily decreasing due to increasing herbicide resistance. It seems very important to address and effectively deal with the main weed management challenges (low crop yield and environmental pollution) by investigating the potential of newly introduced materials, such as biocompatible polymer-based nanoparticles. The current review aims to encourage agricultural or environmental researchers to conduct new research on the synthesis and application of modified herbicides, such as nanoherbicides, for application in weed management and to provide a comprehensive foundation on the topic. Such nanosystems could help with the promotion of the controlled release of active ingredients and extend their action time, resulting in a reduction in dose and application number; improve the physical and chemical characteristics of the herbicide to increase foliar adhesion; prevent degradation that results from environmental factors (such as sunlight, temperature, microorganisms, or pH); and decrease herbicide leaching and contamination of the environment. Furthermore, it has been indicated that some polymeric nanocarriers can penetrate biological barriers, including membranes and plant cell walls, and translocate across vascular tissues, resulting in a more efficient delivery of active ingredients. Poly(epsilon-caprolactone) is a biocompatible material that is easily decomposable by enzymes and fungi. PCL nanoparticles could be applied as nanocarriers of herbicides in agriculture due to their low toxicity, their potential for large-scale synthesis from inexpensive materials, their ability to dissolve herbicides, their high loading capacity, and their ability to help minimize the chemical decomposition of herbicides.
