Diniconazole is a systemic and broad-spectrum triazole fungicide, that has been used widely in cereals, fruit trees, vegetables, and economically important crops to control a wide variety of diseases like scab, septoria, brown rust, powdery mildew, and Rhynchosporium. It controls basidiomycetes and ascomycetes by suppressing 14α-demethylation, which plays an important role in ergosterol biosynthesis.

Diniconazole has to be monitored in the Multiannual Control Programme for Pesticides Residues (MACP), run within the EU and EFTA in/on products of plant origin.

As per Regulation (EC) No 1107/2009 diniconazole is not approved in European Union. The maximum residue limit (MRL) for diniconazole as a sum of isomers has been set from 0.01 to 0.05 mg/kg for various products of plant and animal origin following Regulation (EU) No 1317/2013.
Application
It is intended to be used as a certified reference material (CRM) for calibration in chromatography and other analytical techniques. Diniconazole CRM may also find its use as described below:¹H NMR-based metabolomics and histopathological examination to evaluate the toxicological effects of diniconazole in zebrafish
Ultrasensitive determination of diniconazole in environmental water samples using copper indium sulfide quantum dots (CuInS₂ QDs) as a chemiluminescence probe
Enantioselective determination of diniconazole enantiomers residues in apple, grape, and tea samples using supercritical fluid chromatography coupled with quadrupole-time-of-flight mass spectrometry (SFC-Q-TOF/MS)
Investigation of diniconzole and triadimefon as chemical corrosion inhibitors for freshly polished copper in synthetic seawater
Ratiometric fluorescence detection of diniconazole using a molecularly imprinted mesoporous structured probe
