Trietazine is a chemical compound from the triazine group .


Trietazine is a flammable, difficult to ignite, colorless solid that is practically insoluble in water. It decomposes when heated. The degradation of the compound in the soil (and when exposed to strong bases and acids ) takes place with elimination of chlorine to form the hydroxy compound, dealkylation of the side chains and ring cleavage.


Trietazin is a selective pre-emergence herbicide discovered by Geigy in the late 1950s and introduced by Fisons (now Bayer CropScience ) . It is absorbed through the roots and leaves of the treated plants and intervenes in the photosynthesis of the plants by inhibiting electron transport in photosystem II (inhibition of the Hill reaction ). For weed control, trietazine is mostly used in combination with other active ingredients, for example linuron , especially in potato cultivation. In Japan it is used on chrysanthemums .

Trietazin was approved in Germany from 1975 to 1986.
