PROVISIONAL SPECIFICATION.
[Communicated from abroad by the firm of A. G. PUMMERER, of Wels, Upper
Austria, in the Empire of Austria.]
An Improved Fluid Insecticide.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co. Patent
Agents, 45 Southampton Buildings in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
The present invention relates to a new fluid insecticide to be used more especially
against parasites injurious to plants, vines and woods particularly the phylloxera
vastatrix and the dispar monacha. It may also be used for destroying the
peronospora and other insects.
The improved insecticide is termed "Berkefeld's Salus Plantarum."
The preparation of the fluid is effected as follows. The fruit of the horse-chesnut
(aesculus) is crushed to the form of a paste and is diluted with several volumes of
water. When the water has dissolved the soluble matter of the horse-chesnut the
resulting solution will constitute one of the ingredients of the salus plantarum.
The second ingredient is formed of resin so dissolved in a solution of carbonate of
soda that it can be diluted with water. A suitable proportion is 3 pounds of resin
with one pound of crystallised carbonate of soda and about one pint of water,
although this proportion may vary according to the quality of the resin and the
amount of water contained in the soda.
The first ingredient (extract of horse-chesnuts) is now mixed with more or less
of the second ingredient (solution of resin) according to the amount of adhesiveness
desired. The action of the insecticide takes place without in any way injuring the
health of the plants.
In using the insecticide it may be diluted with water according to the character
of the insect to be destroyed.
COMPLETE SPECIFICATION.
An Improved Fluid Insecticide.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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:-
The present invention relates to a new fluid insecticide to be used more especially
against parasites injurious to plants, vines and woods particularly the phylloxera
vastatrise and the dispar monacha. It may also be used for destroying the
peronospora and other insects.
The improved insecticide is termed "Berkefeld's Salus Plantarum."
The preparation of the fluid is effected as follows. The fruit of the horse-
chestnut (aesculus) is crushed to the form of a paste and is diluted with several
volumes of water. When the water has dissolved the soluble matter of the horse-
chestnut the resulting solution will constitute one of the ingredients of the salus
plantarum.

resin with one pound of crystallised carbonate of soda and about one pint of water,
although this proportion may vary according to the quality of the resin and the
amount of water contained in the soda.
The first ingredient (extract of horse-chestnuts) is now mixed in the proportion
of about one part of the same to about two parts of the second (solution of resin)
according to the amount of adhesiveness desired. The action of the insecticide
takes place without in any way injuring the health of the plants.
In using the insecticide it may be diluted with water according to the character
of the insect to be destroyed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to me
by my foreign correspondent I declare that what I claim is :-
1. A fluid insecticide consisting of an extract of horse-chestnuts and a solution of
resin, substantially as described.
2. The process of manufacturing the extract of horse-chestnuts and the solution
of resin, substantially as and for the purpose described.
Dated this 27th day of May 1892.
