Activity
Fungicide

Triticonazole has contact and systemic activity with uptake via the seed coats and roots. It is effective against ascomycete and basidiomycete fungi. After sowing, triticonazole diffuses into the rhizosphere from where it can be absorbed by the roots of the germinating seed and translocated throughout the growing plant in the xylem. It controls seed-borne and soil-borne diseases. At higher application rates it also controls stem and foliar diseases until late in the growing season.

Triticonazole does not delay plant emergence as is the case with some other fungal sterol biosynthesis inhibitors and does not affect the same pathway in plants.

It is recommended that fungicides with different modes of action are used in rotation with triticonazole to avoid the build up of disease resistance.

Fate in soil:
Triticonazole is very slightly mobile in soil. The soil half-life is 12-16 weeks. As it will be applied as a seed treatment, there is only a very slight risk of contamination of either ground or surface water.

Fate in aquatic systems:
Under abiotic conditions, triticonazole is stable to hydrolysis.
