The Influence of Humic Acids and Nitrophenols on Metabolic Compounds and Pesticide Behavior in Wheat under Biotic Stress

Organic biostimulators support wheat growth in unfavorable conditions; however, to date, multifactorial assessments of their role the plant–pesticide–pathogen system have been poorly investigated. The goal this study was evaluate changes metabolite profile (protein, carbohydrate, phenolic compounds, acid phosphatases, and amino acids) antioxidant potential (antioxidant enzymes) that is infested with F. culmorum exposed humic acids, nitrophenols, six pesticides. Additionally, concentration mycotoxins grain dissipation time pesticides plants were determined. In experiment, we explored differentiated activities acids nitrophenols metabolism during fungal pathogenesis pesticide protection. Nitrophenols decreased oxidative stress through induced catalase activity. contrast, contributed highest enhancement total level carbohydrates (27%) inoculated wheat. Both reduced mycotoxin (DON, 3-AcDON, 15-AcDON, NIV) by 32% increased (13%). Unexpectedly, shortened degradation (DT50) spiroxamine up 60% overall results provide novel information on metabolites, defense, pesticide–biostimulator–pathogen system.
