An Improved Means for the Destruction of all Insects in Greenhouses
or other Horticultural Structures and the like and also in the
Open Air.
WILLIAM WILLIAMSON, Avondale Vale, Guernsey, and 10, Mauldslie Place,
Partick, Scotland, Fruit Grower and Chemist's Assistant, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an improved fumigant, and means, for destroying all
insects, such as, mealy bug; green, white, and black fly; thrip, and such
like insect pests, which attack fruit trees, vines, tomato plants, and all other
plants, susceptible to the ravages of all such like insects, and which are grown
in glass houses, or other horticultural structures, or in the open air, the plants
or trees in the open air, being covered with a tent, canopy, or other suitable
covering, for the purpose of concentrating the fumes, vapour, or gas, from the
fumigant.
According to my invention the desired result will be obtained by vapourising
a quantity of ferrocyanide of potassium or sodium; or ferricyanide of potassium
or sodium; and the acid sulphate of potassium or soda, or any other acid sulphate,
or any preparation, or substance containing, or having absorbed, sulphuric acid, or
any other acid, in the free state.
The vapourising is accomplished by dissolving 4 oz. ferrocyanide of potassium
or sodium or ferricyanide of potassium or sodium in 10 oz. water, and adding
8 oz. of acid sulphate of soda, or potassium, or any preparation as mentioned
above, the solution, being placed in a suitable vessel, heat is applied to it, to
boiling point, by means of a spirit stove, or lamp, or an oil stove, or lamp, or
other suitable contrivance. It must be understood that I do not restrict myself
to the quantities before-mentioned, as it may be found necessary to use more or
less of the ingredients mentioned, in actual working operations, according to the
kind of insect to be dealt with; and according to other circumstances; which
may be connected with the operation.
In the application of my invention for the purpose of vapourising the fumigant,
a suitable vessel or recepticle for holding the fumigant, and a spirit stove or
lamp or an oil stove, or lamp, or any other suitable contrivance may be used.

page_text: 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:-
This invention relates to an improved fumigant, and means for destroying all
insects such as mealy bug; green, white, and black fly, scale, thrip and such
like insect pests which attack fruit trees, vines, tomato plants and all other
plants, susceptible to the ravages of all such like insect pests and which are grown
in glass houses or other horticultural structures, or in the open air, the plants
or trees in the open air being covered with a tent, canopy, or other suitable
covering, for the purpose of concentrating the fumes vapour or gas, from the
fumigant.
According to my invention the desired result will be obtained by vapourising
a quantity of ferrocyanide of potassium or sodium, or ferricyanide of potassium
or sodium; and the acid sulphate of potassium or the acid sulphate of soda or
any other acid sulphate, or any preparation, or substance containing or having
absorbed, sulphuric acid, or any other acid in the free state.
The vapourising is accomplished by dissolving about 4 oz. ferrocyanide of potas-
sium or sodium or 4 oz. ferricyanide of potassium or sodium in 10 oz. water and add-
ing 6 oz. of acid sulphate of soda or potassium or any preparation as mentioned above,
the solution being placed in a suitable vessel, heat is applied to it to boiling
point by means of a spirit stove or lamp or other suitable contrivance.
It must be understood that I do not restrict myself to the quantities above
mentioned as it may be found necessary to use more or less of the ingredients
mentioned in actual working operations, according to the kind of insects, inicrobes,
and such like, which are to be dealt with, and according to other circumstances,
which may be connected with the operation.
The ingredients being in the form of dry powders can be distributed for sale
in a very suitable and useful form and obviates the necessity of the handling
and transit of sulphuric acid.
In the application of my invention for the purpose of vapourising the fumigant,
a suitable vessel, or receptacle for holding the fumigant, and a spirit stove, or
lamp, or any other suitable contrivance, may be used.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. For the purpose of destroying insects and such like pests in greenhouses,
and wherever such may be found, a combination of potassium ferrocyanide or
ferricyanide, and acid sulphates in the form of powders, substantially as described.
2. A new method of producing hydrocyanic acid gas, substantially
described.
as
3. The improved means for destroying insects, microbes, and all such pests,
in greenhouses and wherever they may be found, substantially as described.
