Formula For Lime-sulphur
Categories: Pests and Diseases of PlantsTo make lime-sulphur take quick-lime, 20 pounds; ground sulphur, 15
pounds and water 30 gallons. Slake the lime with hot water in a large
kettle, add the sulphur and stir well together. After the violent
slaking subsides add more water and boil the mixture over a fire for at
least one hour. After boiling sufficiently strain into the spray tank
and dilute with water to the proper strength. If a steam boiler is
available, this mixture may be prepared more easily on a large scale by
cooking in barrels into which steam pipes are introduced. This mixture
cannot be applied safely except during the winter when the trees are
dormant. A large proportion of the lime-sulphur used in the State is
purchased already prepared in more concentrated form.
