Propiconazole is a triazole fungicide, also known as a DMI, or demethylation inhibiting fungicide due to its binding with and inhibiting the 14-alpha demethylase enzyme from demethylating a precursor to ergosterol. Without this demethylation step, the ergosterols are not incorporated into the growing fungal cell membranes, and cellular growth ...

This is a list of fungicides.These are chemical compounds which have been registered as agricultural fungicides.The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [1]
A triazole is a heterocyclic compound featuring a five-membered ring of two carbon atoms and three nitrogen atoms with molecular formula C 2 H 3 N 3.Triazoles exhibit substantial isomerism, depending on the positioning of the nitrogen atoms within the ring.
Research with chlorothalonil and tebuconazole in the 1990s showed that 4–5 applications of the fungicides on a two-week schedule when vegetative buds are breaking dormancy is ideal for control of EFB. [106] The state of Oregon has estimated that if left uncontrolled EFB could eliminate half of the state's hazelnuts within ten years. [107]
The dermal LD 50 amounted to more than 2000 mg/kg bw, whereas a 4-hour inhalation LC 50 was determined to be over 4.9 mg/L. Short term studies assessed adverse hepatic effects, an increase in liver weight, increased activity of liver enzymes and microscopic lesions. Prothioconazole was reported to be irritating to rabbit eyes but not skin.
For wood preservation, other azoles such as propiconazole, tebuconazole and cyproconazole, are used as antifungal agents in several wood products or structures, with or without the addition of copper-containing compounds.
The first synthesis of azoxystrobin was disclosed in patents filed by the ICI group. [13] The sequence of the two substitution reactions allows for the synthesis of a diverse range of structural analogs via an Ullmann-type etherification between the aryl chloride of the first intermediate and a substituted phenol, thus introducing a range of structural diversity while maintaining the central ...
