“…These results agree with those observed for CB2011‐509 and VR808 with respect to the number of tubers, but there were much lower values in terms of the highest biomass values recorded in our experiment, indicating the greater size and weight of the tubers in our study. Regarding the use of fungicides, research has focused on the efficacy of these compounds to improve yields, which are strongly affected by pathogenic fungi such as Phytophthora infestans , Rhizoctonia solani or Fusarium proliferatum in wheat and potato crops; 37‐39 however, there is no information about interactions with individual AMF isolates. Therefore, it is not possible to corroborate whether the decrease in performance due to the fungicide observed in some cases is related to AM characteristics, such as the percentage of colonization or the density of other fungal structures.…”

Metabolic and antioxidant effects of inoculation with arbuscular mycorrhizal fungi in crops of flesh‐coloured Solanum tuberosum treated with fungicides

BACKGROUND: Solanum tuberosum tubers have higher content of phenolic compounds such as hydroxycinnamic acid derivatives (HCAD) and anthocyanins in coloured genotypes. The use of fungicides for crops is common, but there are few studies regarding the interaction of fungicides and arbuscular mycorrhizal fungi (AMF). Here, the AMF-plant interactions and the metabolic responses of three potato genotypes with different tuber colorations (VR808, CB2011-509 and CB2011-104) inoculated with Claroideoglomus claroideum (CC), Claroideoglomus lamellosum (HMC26) or Funneliformis mosseae (HMC7) were studied together with the use of the fungicides MONCUT (M) and ReflectXtra (R). Mycorrhizal traits, phenolic compound profiles and antioxidant activity (AA) were evaluated.RESULTS: Despite only two HCADs being identified, with 5-caffeolquinic acid the most abundant, four anthocyanins were detected only in purple potato genotypes. The anthocyanin and HCAD profiles, as well as AA, showed that the CB2011-104 genotype had better characteristics than the other genotypes, while VR808 and CB509 showed similar responses. The responses were dependent on the specific combinations of genotype, fungicide and the AMF strain, and generally showed better responses when colonized by AMFs.CONCLUSION: The three potato genotypes had differential responses depending on the inoculated AMFs and the fungicide applied before sowing, where the optimal combinations for antioxidant response, mycorrhization degree and performance were HMC26/R for VR808, HMC7/M for CB2011-509 and HMC26/M for CB2011-104. Our results suggest the existence of functional compatibility that can be registered as beneficial effects even at the genotypic level of the host regarding a specific AMF strain.

“…However, under the long-term application of chemical fungicides in agriculture, microorganisms have gradually developed antimicrobial resistance, which largely reduces the effectiveness of fungicides [ 12 ]. In this case, fungicides are excessively and repeatedly used to control the diseases, causing a series of problems such as chemical residue, environmental pollution and some undesirable effects on non–target organisms [ 13 , 14 , 15 ]. Thus, the development of alternative strategies to improve the efficacy of fungicides and, at the same time, minimize their side effects has been an important research topic in both agricultural and environmental chemistry.…”

Synergistic Antifungal Activity of Graphene Oxide and Fungicides against Fusarium Head Blight In Vitro and In Vivo

et al. 2021

Plant pathogens constantly develop resistance to antimicrobial agents, and this poses great challenges to plant protection. Therefore, there is a pressing need to search for new antimicrobials. The combined use of antimicrobial agents with different antifungal mechanisms has been recognized as a promising approach to manage plant diseases. Graphene oxide (GO) is a newly emerging and highly promising antimicrobial agent against various plant pathogens in agricultural science. In this study, the inhibitory activity of GO combined with fungicides (Mancozeb, Cyproconazol and Difenoconazole) against Fusarium graminearum was investigated in vivo and in vitro. The results revealed that the combination of GO and fungicides has significant synergistic inhibitory effects on the mycelial growth, mycelial biomass and spore germination of F. graminearum relative to single fungicides. The magnitude of synergy was found to depend on the ratio of GO and fungicide in the composite. In field tests, GO–fungicides could significantly reduce the disease incidence and disease severity, exhibiting a significantly improved control efficacy on F. graminearum. The strong synergistic activity of GO with existing fungicides demonstrates the great application potential of GO in pest management.

“… 28,29 The MIC value of tebuconazole fungicide on F. proliferatum was greater than 10 mg mL −1 . 7,30 Compared with tebuconazole, we found that the inhibition effect depends on the concentration of MNQ. F. proliferatum was completely killed by MNQ at the concentration of 8 mg L −1 , which may be more effective and safer.…”

“… 6 At present, industrial fungicides are used to manage Fusarium as agricultural techniques and biological methods only give little alleviation from the disease. 7 Fusarium is only controlled with a few industrial fungicides. However, these widely used chemical fungicides are limited by several serious problems, 8 such as serious residual toxicity, the development of drug resistance, environmental pollution, and health hazards.…”
