Sensitivity to demethylation‐inhibiting fungicides and induced expression of CYP51 associated with tebuconazole resistance in Alternaria species on mandarin in Brazil

open access: yesPest Management Science, EarlyView.
Tebuconazole‐resistant isolates overexpress CYP51 and, when tested at field rates, did not reduce ABS severity, whereas difenoconazole and mefentrifluconazole remained effective. Abstract BACKGROUND Alternaria brown spot (ABS), caused by Alternaria spp., is an important disease affecting mandarin production in several citrus‐growing regions worldwide ...

Decreased DMI sensitivity of Plenodomus biglobosus (phoma of oilseed rape) associated with CYP51 substitution G476S

open access: yesPest Management Science, EarlyView.
Here, we report for the first time a target site mutation in the CYP51 gene of the oilseed rape phoma stem canker fungus Plenodomus biglobosus (Leptosphaeria biglobosa) that is associated with decreased sensitivity to sterol demethylation inhibitor fungicides.

Dissipation Kinetics of Tebuconazole Residues in Grape

open access: yesEuropean Journal of Engineering and Technology Research, 2018
Tebuconazole residues were determined on grapes treated with minimal and maximal recommended concentrations. The grapes samples were collected randomly after 1, 5, 10, 15 days after last application, extracted using the ethyl acetate method, and finally analyzed with a gas chromatograph instrument.

Fragments of a Wheat Hevein-Like Antimicrobial Peptide Augment the Inhibitory Effect of a Triazole Fungicide on Spore Germination of Fusarium oxysporum and Alternaria solani

open access: yesAntibiotics, 2020
There are increasing environmental risks associated with extensive use of fungicides for crop protection. Hence, the use of new approaches using natural plant defense mechanisms, including application of plant antimicrobial peptides (AMPs), is of great ...

De Novo Design and Synthesis of Novel Benzoxazinone Derivatives Targeting Dihydroxyacid Dehydratase

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Dihydroxyacid dehydratase (DHAD), a key enzyme in the branched‐chain amino acid (BCAA) synthesis pathway, is a promising herbicide target. Currently, no commercial herbicides target DHAD, and no inhibitors are in development. Structural analysis suggests that coordination with iron–sulfur clusters and hydrophobic interactions with Tyr215 and ...

Efficacy and phytotoxicity of various thiabendazole and tebuconazole ratios in a fungicidal mordant [PDF]

open access: yesBIO Web of Conferences
When developing combined preparations, a possible phytotoxic effect should be considered, depending on the dose of the mordant. Fusarium oxysporum and Pyrenophora graminea strains were cultured in a liquid enrichment culture with the addition of ...

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

open access: yesBiological Reviews, Volume 101, Issue 1, Page 106-127, February 2026.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Degradação fotocatalítica do fungicida tebuconazole em solução aquosa Tebuconazole photocatalytic degradation kinetics

open access: yesQuímica Nova, 2010
The tebuconazole photocatalytic degradation kinetics was studied in a batch reactor using TiO2 (P25-Degussa) as catalyst and a high pressure mercury lamp. The photolysis, adsorption and irradiation effects in the reaction rate were evaluated. Afterward, the suspension catalyst concentration and initial pH to the maximum reaction rate was determined. It
