Tetraconazole

Tetraconazole controls powdery mildew, brown rust, Septoria and Rhyncosporium on cereals; powdery mildew and scab on apples; powdery mildew on vines and cucumbers; powdery mildew and beet leaf spot on sugar beet and powdery mildew and rust on vegetables.

Tetraconazole is an conazole fungicide used to control pests in apple and strawberries.

Agricultural fungicide.

The production of tetraconazole involves a multi-step synthetic route starting from 2,4-dichlorophenylacetic acid. First, this acid is esterified using methanol and concentrated sulphuric acid under reflux to form the corresponding methyl ester. This intermediate is then reacted with ethyl acrylate and subjected to a series of transformations involving paraformaldehyde, potassium carbonate, and dimethyl sulfoxide at elevated temperatures to build the core side chain. The resulting compound is further modified by introducing the 1,2,4-triazole ring, typically through nucleophilic substitution or condensation reactions, yielding the final active ingredient.

ChEBI: 1-[2-(2,4-dichlorophenyl)-3-(1,1,2,2-tetrafluoroethoxy)propyl]1,2,4-triazole is a member of the class of triazoles that is 1,2,4-triazole substituted at position 1 by a 2-(2,4-dichlorophenyl)-3-(1,1,2,2-tetrafluoroethoxy)propyl group. It is a member of triazoles, a dichlorobenzene, an ether and an organofluorine compound.

Systemic with protectant, eradicant and curative properties. Sterol biosynthesis inhibitor, acts mainly on the vegetative stages of fungi by blocking the mycelial growth either inside or on the surface of the host plant.

There is little published information available.

Tetraconazole decomposes at 240 °C without boiling. It is stable in dilute solutions at pH 5 to 9 and, in water, it is stable to sunlight (PM).
