Improvements in Compounds for Protecting Vines, Potatoes, and
other Vegetable Growths from Disease.
Communication from ALFRED WILBY TAIT, residing at Oporto, Portugal,
Merchant.
I, ALLAN BUCHANAN, of Princes Square, Glasgow, in the County of Lanark,
North Britain, Merchant, do hereby declare the nature of this invention to be as
follows, that is to say :-
The said invention has for its object the protection or preservation of vines,
potatoes, and other vegetable growths from disease.
In carrying out the invention a compound is formed by slaking caustic lime with
a solution of sulphate of copper and subsequently adding and mixing in flowers of
sulphur. The proportions of the ingredients may be varied but the lime is by
preference in excess in the final compound. The water of the solution of sulphate
of copper is by preference little if at all in excess of what is required to slake the
lime so that the product may be in the form of a dry powder. The copper of the
sulphate of copper, is precipitated in a state of very fine division and is very
uniformly distributed amongst the lime. The copper may be precipitated separately
in any convenient known way: and be afterwards mixed with the lime and sulphur;
and other suitable metallic sulphates may be substituted for the sulphate of copper:
but the process of slaking the lime with solution of sulphate of copper is believed to
be preferable.
The compound, which is in the form of a fine powder, may be applied by dusting
or by blowing, to the leaves or other parts of the plants.

Improvements in Compounds for Protecting Vines, Potatoes, and
other Vegetable Growths from Disease.
Communication from ALFRED WILBY TAIT, residing at Oporto, Portugal,
Merchant.
I, ALLAN BUCHANAN, of Princes Square, Glasgow, in the County of Lanark,
North Britain, Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, that is to say :—
The said invention has for its object the protection or preservation of vines,
potatoes, and other vegetable growths from disease.
In carrying out the invention according to one modification, a compound is formed
by slaking caustic lime with a solution of sulphate of copper, and subsequently
adding and mixing in flowers of sulphur. The proportions of the ingredients may
be varied, but the lime is by preference in excess in the final compound. The
water of the solution of the sulphate of copper is, by preference, little if at all in
excess of what is required to slake the lime, so that the product may be in the form
of a dry powder. The copper of the sulphate of copper is precipitated in a state of
very fine division and is very uniformly distributed amongst the lime. The copper
may be precipitated separately in any convenient known way; and be afterwards
mixed with the lime and sulphur; and other suitable metallic sulphates such as

page_text: sulphate of iron may also be added; but the process of sinking the lime with
solution of sulphate of copper is believed to be preferable.
As hereinbefore stated the proportions of the ingredients may be varied but by way
of example I may state that compounds suitable for horticultural and agricultural
purposes respectively are made with the following proportions.
For the horticultural compound, ten parts by weight of crystallised sulphate of
copper, twenty parts of lime, and seventy parts flowers of sulphur; and for the
agricultural compound, ten parts by weight of "rystallised sulphate of copper,
twenty parts of lime, thirty five parts sulphur and thirty five parts of gypsum,
steatite, china clay or the like.
The compound which is in the form of a fine powder, may be applied by dusting
or by blowing, to the leaves or other parts of the plants.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is:
1-Improved compounds for protecting vines, potatoes, and other vegetable
growths from disease, having as principal ingredients precipitated copper, lime, and
sulphur, substantially as hereinbefore described.
2-Preparing compounds for protecting vines, potatoes, and other vegetable
growths from disease, by slaking lime with solution of copper and adding and
mixing in sulphur, with or without other ingredients, substantially as hereinbefore
described.
