SUMMARY

Hazard alerts

The following 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. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

Formulation and application details

Usually supplied as wettable granules

Commercial production

In industrial settings, the synthesis of tolylfluanid begins with the reaction of 4-methylbenzenesulfonyl chloride with dimethylamine, forming a sulfonamide intermediate. This compound is then reacted with dichlorofluoromethylthio reagents to introduce the active fungicidal moiety. The process requires precise control of temperature, pH, and reaction time to ensure high purity and yield. After synthesis, the product is crystallised, filtered, and dried before being formulated.
