Insecticides for Plants

Two formulas for insecticides with especial reference to vermin which attack plants:

1. – Kerosene………………...…..    2 gallons
Common soap……………....…...    ½ pound
Water…………………………...…     1 gallon

Heat the solution of soap, add it boiling hot to the kerosene and churn until it forms a perfect emulsion. For use upon scale
insects it is diluted with 9 parts of water; upon other ordinary insects with 15 parts of water, and upon soft insects, like
plant lice, with from 20 to 25 parts of water.

For lice, etc., which attacks the roots of vines and trees the following, is recommended:

2. – Caustic soda………….…..      5 pounds
Rosin………………………....…    40 pounds
Water, a sufficient quantity.

Dissolve the soda in 4 gallons of water, by the aid of heat, add the rosin and after it is dissolved and while boiling add, slowly,
enough water to make 50 gallons. For use, 1 part of this mixture is diluted with 10 parts of water and about 5 gallons of the
product poured into a depression near the root of the vine or tree.

Peppermint oil, 16 parts; ammonia water, 60 parts; calomel, 30 parts; and linseed oil, 1,000 parts.
