“…Similarly, the multiple omics analysis revealed that MT (100 μM) foliar application regulated the phenylpropanoid pathway and antioxidant system in Chinese hickory plants under drought stress . The current research demonstrated that MT could promote the degradation of pesticides by regulating glutathione cycling and increasing the activities of detoxification and antioxidant enzymes. − MT enhanced plant abiotic tolerance, although herbicide stress reduction is uncertain. Se elements boost the antioxidant system, repair cell structures, and regulate plant metabolisms, protecting plants from environmental stress .…”

“…. 20 MT could reduce carbendazim on tomato plants by stimulating the ascorbateglutathione cycle and participating in glutathione S-transferasemediated pesticide decontamination. 21 MT application similarly expedited the degradation of chlorothalonil, malathion, and glyphosate in jujube fruit by promoting glutathione synthesis and increasing the activities of detoxification enzymes.…”

“…Additionally, MT is essential for pesticide detoxification. Fathi et al found that MT (150 μM) decreased the damages of paraquat through the improvement in photosynthetic properties ( Chla , Chlb , and carotenoid) and antioxidant capacity (enhanced in SOD, CAT, APX, POD, decreased in MDA and H 2 O 2 ) . MT could reduce carbendazim on tomato plants by stimulating the ascorbate-glutathione cycle and participating in glutathione S-transferase-mediated pesticide decontamination .…”

Nanoselenium (nano-Se) or melatonin (MT) foliar spray reduces pesticide stress by stimulating plant secondary metabolism and antioxidant capacity. However, the effects of nano-Se and MT biofortification on the interaction between plant secondary metabolic pathways and rhizosphere microbes in mitigating 2,4-D butyrate stress remain unknown. Compared to nano-Se or MT treatment alone, nano-Se and MT combined application increased the antioxidant enzyme activities and decreased the MDA (25.0%) and H 2 O 2 (39.3%) contents with 2,4-D butylate exposure. Importantly, they enhance the soil enzymes (S-FDA by 53.1%), allelochemicals (luteolin by 164.1% and tricin by 147.3%), as well as plant secondary metabolites (JA by 63.3% and 193.3% in leaves and roots) levels. It also improved the beneficial microbial abundance of Comamonadaceae, Sphingomonadaceae, and Rhodobacteraceae in the rhizosphere soil. In conclusion, nano-Se and MT alleviate 2,4-D butylate stress in wheat plants by enabling the interaction between rhizosphere microorganisms, allelopathic substances, and secondary metabolites.

“…The pre-treatment of MT in Bermuda grass may reduce the production of H 2 O 2 and modulate plant growth, and alleviate ROS accumulation by modulating ROS synthesis and accumulation [ 101 ]. Furthermore, MT mitigates paraquat-induced oxidative stress in Zea mays [ 102 ], Arabidopsis [ 51 ], and Pisum sativum [ 103 ]. In Arabidopsis , MT inhibits cadmium accumulation by modulating various heavy metal transporter genes, such as ABC transporters and PLANT CADMIUM RESISTANCE 2 ( PCR2 ), and downregulating the miR398 ; a micro RNA that negatively regulates the Cu/Zn Superoxide Dismutase genes ( CSD1 and CSD2 ).…”

“…Their results showed that this specific plant-based biostimulant was able to prevent excess herbicidal stress to barley's dry biomass 21 days after the seed treatment, with the application rates being insignificant. Melatonin has also been used to prevent herbicidal stress induced by paraquat application on maize, which interacts with the electron transfer components associated with Photosystem I [53]. Seed priming with melatonin proved that it could demonstrate tolerance to paraquat in sweet corn by increasing the activity of the antioxidant enzymes.…”

Over the last decades, biostimulants have been the center of discussion as a sustainable cultivation practice to promote plant growth and protect crops from abiotic stress. Agrochemical products are abundantly used for this purpose, which has resulted in raised international concern. Biostimulants, when used in combination with herbicides in some cases, could act as safeners, reducing the harmful and stressful effects of herbicides, and as a result, this combination can be considered a relatively new agricultural technique. However, they can also have adverse or non-significant effects, something that is strongly affected by the operating mechanisms of their components. In practice, there is a need to identify plant species-biostimulant-herbicide working systems from all the stakeholders of agricultural production. While research is still in its early stages, several studies have been conducted to evaluate various biostimulant and herbicide combinations to contribute to this goal. In this review, studies of their combination in sequential or mixed tank applications have been gathered to see how and if each specific combination can have a potential use in agricultural practice. The results indicated that there are various effects on crops, some of which were positive and others negative or non-significant. The fact that there is a countless number of possible plant species-biostimulant-herbicide combinations to be evaluated is a challenging task. Nevertheless, this review could serve as a foundation for the upcoming research. The aim of this review is to summarize the knowledge of some successful working examples of these three factors that could facilitate the incorporation of biostimulant and herbicide application, either sequentially or in a tank mixture, as a part of the agricultural practice for field crops.
