Due to the fine milled sulfur there are far more sulfur particles available to cover and protect the leaf surface by applying Wettable Sulfur Stulln than by using dust formulations. Wettable Sulfur Stulln forms a protective net on the leaves.

Sulfur particles, evenly distributed on the leaf surface act immediately through contact and vapor action against the target fungi. Sulfur vapor easily enters the fungal cell and is enzymatically converted to hydrogen sulfide which is active against the pest. On the leaves sulfur particles can be converted to sulfur dioxide under the influence of humidity, light and oxygen.

The efficacy of sulfur as a plant protection agent depends on the concentration of elemental sulfur in the vapor phase  which is related to the air temperature.
