Lime Sulphur - the inside story

How to make Lime Sulphur

 - Eugenio Gras' method


Lime sulphur is used to control and prevent infestations including fungal attacks, in crops. It can be made, outside, and with due care, by anyone, see video of Eugenio Gras demonstraing the process to some of his students at:


For convenient reference, the process and materials are detailed below.



10 litres water – non chlorinated

1 kilo builder's lime (not agricultural lime): also called calcium hydroxide or hydrated lime

2 kilos sulphur


Mix dry ingredients whilst bringing water to the boil in suitable large container (outside over open fire).

When mixed, add dry ingredients to the pot of boiling water and stir well with a long stick (so you don't have to bend low over the pot). Continue simmering and stirring for 35-45 minutes till colour changes to red, indicating that the sulphur and lime have chemically combined.  During the process, sprinkle with cold water from time to time to prevent contents boiling over.


Do not allow the sulphur to get into the fire when adding to the pot (it is flammable).

When cooled, the red liquid suspension is poured off into nother vessel.  It can be used to spray crops such as fruit trees to prevent and treat fungal diseases. The green paste residue can be used to seal the wounds left on trees from pruning to prevent fungal and other diseases.
