“…An increase in the relative abundance of Solicoccozyma under the influence of pesticides has been previously found [42]; representatives of this genus have been shown to be able to degrade glyphosate [43]. The relative abundance of Humicola decreased under the influence of difenoconazole [44]. A number of genera were also found to be affected by pesticides in the field experiment but not in the laboratory.…”

Pesticide preparations based on benomyl, metribuzin and imidacloprid were used on a potato plot for three years. Every year soil samples were taken at 0, 7, 14, 28, 56 and 84 days after treatment. For all samples, the pesticide residues in the soil were measured. A study of the soil’s bacterial and fungal community structures was preformed using next-generation sequencing. It was found that the rate of decomposition of the pesticides increased every year, while the pesticides affected only certain phylogenetic groups of microorganisms. The most significant effect was the decrease in the proportion of Ascomycota. Additionally, in the field, as well as previously in the laboratory, pesticides have had an impact on the relative abundance of the genera Haliangium, Solicoccozyma and Humicola. It can be assumed that the repeated application of pesticides does not have a significant effect on the microbial communities of soils, provided that they are applied according to the application rate.

“…Due to their ease of use, low cost, and effectiveness, triazole fungicides became the primary means of fungi infection control and has important roles in protecting fruits and vegetables from fungi diseases such as apple anthracnose, cucumber powdery mildew and pear scab, thus improving crop yield (Gao et al 2022;Liu et al 2022;Yeon et al 2022). Misusing these agrochemicals has led to ecological hazards, including terrestrial and aquatic ecosystem health, food, and environmental safety (Marinho et al 2020).…”

Studies have shown that exposure to either fungicide difenoconazole (DIF) or salt (NaCl) alone can cause phytotoxicity in plants, but it remains uncertain whether co-exposure to these two xenobiotics, which often co-occur in the agroecosystem, can also induce phytotoxicity. This research aimed to study the phytotoxicity and underlying mechanisms of co-exposure to DIF (field recommended doses (0.5 L ha− 1) and NaCl (150 mM) in tomato seedlings. The results showed that exposure to DIF and/or NaCl causes phytotoxic effects in tomato seedlings, including a decrease in fresh weight and length of shoots and roots, damage to chlorophyll pigment, and induced oxidative stress in the leaves. Interestingly, combined exposure to DIF and NaCl exhibited synergistic effects on shoot and root biomass inhibition. Antioxidant defense analyses revealed that the DIF and/or NaCl exposure altered the activities of enzymes involved in the H2O2 scavenging (ascorbate peroxidase and catalase), and in xenobiotic detoxification (glutathione-s-transferase and peroxidase) in leaf tissues. Interestingly, combined exposure to DIF and NaCl markedly enhanced detoxifying enzymes, thereby enhancing xenobiotic biotransformation. In addition, DIF and/or NaCl exposure enhanced proline accumulation, and altered the thiols profile (reduced glutathione) content, while stimulating the phenylpropanoid pathway (phenylalanine ammonia-lyase activity) to produce secondary metabolites such as polyphenols and flavonoids. As pioneer research to highlight the phytotoxicity induced by co-exposure to DIF and NaCl in tomato seedlings, these results provide new insights into physio-biochemical responses of non-target plants to DIF and NaCl co-contamination and shedding light on the ecological risks of pesticides and salt exposure in agroecosystems.
