“…Further, safener treatments are associated with detoxifying cytotoxins and stress‐induced reactive oxygen species (ROS), and as a result lead to increased protection from herbicides, pollutants, and abiotic stresses (Dashevskaya et al., 2013; DeRidder et al., 2002; Jablonkai, 2013; Panfili et al., 2017; Panfili et al., 2019; Riechers & Green, 2017; Riechers et al., 2010; Taylor et al., 2013; Ye et al., 2019). Among the many approaches used to enhance abiotic stress tolerance in plants, exogenous application of agrochemicals such as safeners is considered a new strategy (Abu‐Qare & Duncan, 2002; Bianchi et al., 2020; Dashevskaya et al., 2013; Taylor et al., 2013). Another approach of seed priming using chemicals such as salicylic acid, glycinebetaine, KCl, PEG, GA3 and CaCl 2 has been studied in maize (Farooq et al., 2008; Farooq, Aziz, Basra, Wahid, et al., 2008; Farooq et al., 2008; Farooq, Aziz, Hussain, et al., 2008), and sorghum (Zhang et al., 2015; Pinheiro et al, 2018) to induce abiotic stress tolerance, leading to improved seedling vigour.…”

“…Thus, the protective effect of mefenpyr-diethyl on plants that received this treatment is evident; however, it is not as intense at the highest doses of the herbicide. We emphasize that several factors may be involved in the maximization of the effects of safeners, for example, dose, growth stage of the plant, environmental conditions, absorption and translocation, distribution of antioxidant enzymes, among others (Bianchi et al, 2020). Taylor et al (2013) revealed that, for safeners including mefenpyrdiethyl, the effect on wheat varied based on the plant stage and that the accumulation of GST classes was different in the analyzed plant parts.…”

“…The protective action of the mefenpyr-diethyl safener for the herbicides fenoxaprop-P-ethyl and iodosulfuronmethyl has been reported, resulting in significant improvements in the safety of its application in crops, such as white oats, wheat, rye, triticale, and barley (Hacker et al, 2000;Queiroz et al, 2017). In addition, according to Bianchi et al (2020), the use of mefenpyr-diethyl can stimulate action in wheat and soybean plants.…”

Mefenpyr-diethyl is a foliar-acting safener of the pyrazoline chemical group, and after its absorption, the metabolization and detoxification of herbicides occur in treated plants. Studies have demonstrated the protective effect of this safener for the herbicide fenoxaprop-P-ethyl in grass. Thus, this work aimed to evaluate whether a tank mixture of mefenpyr-diethyl has a protective response to haloxyfop-methyl in non-perennial bahiagrass. The experiment had a completely randomized design and was carried out in a greenhouse, using five replications with a 10x2 factorial scheme and ten doses of haloxyfop-methyl (0.00, 0.24, 0.49, 0.97, 1.95, 3.90, 7.79, 15.59, 31.28, and 62.35 g a.i. ha-1) in the presence or absence of a tank mixture of mefenpyr-diethyl (50 g a.i. ha-1). Phytotoxicity and electron transport rate (ETR) were evaluated at 7, 14, 21, and 28 days after application (DAA), in addition to plant height and dry biomass at 28 DAA. In general, phytotoxicity increased due to the higher levels of the herbicide haloxyfop-methyl. The application of mefenpyr-diethyl, in turn, provided lower levels of phytotoxicity, as well as lower reductions in ETR, height, and dry biomass when compared to untreated plants. These results show the safener action of a tank mixture of mefenpyr-diethyl on low doses of haloxyfop-methyl in non-perennial bahiagrass.

“…17 This safeguarding involves upregulation of ALS in wheat treated with mefenpyr-diethyl. 18 Notably, prior research has shown that within a specific concentration range, increasing mefenpyr-diethyl concentration significantly enhances the ALS activity of wheat. 19 However, whether mefenpyr-diethyl improves mesosulfuron-methyl resistance in wheat remains unverified.…”

Mesosulfuron-methyl, an inhibitor of acetolactate synthase (ALS), has been extensively used in wheats. However, it can damage wheat (Triticum aestivum) and even lead to crop death. Herbicide safeners selectively shield crops from such damage without compromising weed control. To mitigate the phytotoxicity of mesosulfuron-methyl in crops, several purine derivatives were developed based on active substructure splicing. The synthesized title compounds underwent thorough characterization using infrared spectroscopy, 1 H nuclear magnetic resonance ( 1 H NMR), 13 C nuclear magnetic resonance ( 13 C NMR), and high-resolution mass spectrometry. We evaluated chlorophyll and glutathione contents as well as various enzyme activities to evaluate the safer activity of these compounds. Compounds III-3 and III-7 exhibited superior activity compared with the safener mefenpyr-diethyl. Molecular structure analysis, along with predictions of absorption, distribution, metabolism, excretion, and toxicity, indicated that compound III-7 shared pharmacokinetic traits with the commercial safener mefenpyr-diethyl. Molecular docking simulations revealed that compound III-7 competitively bound to the ALS active site with mesosulfuron-methyl, elucidating the protective mechanism of the safeners. Overall, this study highlights purine derivatives as potential candidates for novel safener development.
