| SUMMARY |
| Hazard alerts |
The following Pesticide Hazard Tricolour (PHT) alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. The alerts for Highly Hazardous Pesticides (HHPs) are based on applying the FAO/WHO (Type 1) and the PAN (Type II) criteria to PPDB data. Further details on the HHP indicators are given in the tables below. Neither the PHT nor the HHP hazard alerts take account of usage patterns or exposure, thus they do not represent risk.

| Chemical structure |
|
Prothioconazole exhibits stereoisomerism due to the presence of a chiral centre in its molecular structure. Specifically, it contains a tetrahedral carbon atom bonded to four different substituents, giving rise to two enantiomers. The technical material is a racemate comprising equal amounts of (R)- and (S)-prothioconazole. | |

The production of prothioconazole involves a six-step chemical synthesis that begins with a chlorination cyclisation reaction to form a key intermediate, followed by a Claisen condensation with another compound. This intermediate then undergoes epoxidation, which is subsequently reacted with hydrazine hydrate to form a hydrazine derivative. The next step involves reacting this compound with formaldehyde and thiocyanate to produce a triazole-thione precursor. Finally, oxidation of this precursor yields prothioconazole. | |||
|
Precise life cycle emissions are unpublished but Audsley et al. (2009) reported that it takes 475 MJ of energy per kg produced. This is equivalent to approximately 32.8 kg CO₂e. There will also be emissions associated with packaging, transport and application. |
