Tridemorph is a systemic fungicide that first gained commercial clearance in 1969. An evaluation document to be published later in the year by the UK's Pesticide Safety Directorate (PSD) will report concern over its potential reproductive effects on spray operators. Until recently there has been very little human health and environmental information in the public domain on this active ingredient, yet it is used widely over numerous crops in many countries around the world. Since the common name was approved, it has become known that the active ingredient in the commercial product is a reaction mixture of C11-C14 homologues containing 60-70% of the 4-tridecyl isomer; the Registry Number of the reaction mixture is [81412-43-3].
It is used to control the fungus Erysiphe graminis in cereals, Mycosphaerella species in bananas, and Caticum solmonicolor in tea. Tridemorph is formulated with the fungicide carbendazim, to extend its spectrum of use in cereal disease control. It is also used with a number of other fungicides including: cyproconazole, fenbuconazole, fenpropi-morph, flusilazole, propiconazole, tebucon-azole, triadimenol.

Tridemorph is applied onto many crops across the world, but very little data on usage and production is in the public domain. It was developed in the 1960s by the German multinational BASF who sell tridemorph under the trade name Calixin. In Europe, it is used in Austria, Belgium, Finland, Germany, Greece, Italy, Ireland, Luxembourg, Netherlands, Spain and UK. It is applied widely on banana plantations Latin America, especially Costa Rica and Ecuador.

Applications: controls wide range of diseases (yellow and black sigatoka, pink disease, powdery mildew, etc.), of economic importance to plantation (rubber, tea, etc.), field (barley, wheat, etc.), fruit (bananas, mango, etc.), vegetables (cucurbits).
