Stock Solution 
Pulverized resin 5 pounds 
Concentrated lye i pound 
Fish oil, or any animal oil except tallow . . i pint 
Water 5 gallons 
Place the resin, oil, and a gallon of hot water in an iron kettle 
and heat until the resin is softened, after which the lye should be 
added to the heated mixture and the whole thoroly stirred. Then 
add the remaining four gallons of water and boil for about two 
hours, or until it will unite with cold water and make a clear, amber- 
colored liquid. If there is less than five gallons of the preparation, 
add water enough to make that quantity. This stock solution will 
keep indefinitely, and the quantity needed for the whole season may 
be made up at one time. 
Preparation for Use 
Stock solution i gallon 
Water 16 gallons 
Milk of lime* 3 gallons 
Paris green 54 pound 
First add the water to the stock solution, mixing thoroly ; then 
add the milk of lime; and, finally, add the Paris green, previously 
stirred up with water to form a thin paste. The whole mixture must 
then be thoroly stirred. This preparation should be made up as 
needed, for if allowed to stand any considerable time it will settle, 
and will also gum up the pump valves and the nozzles. 
Bordeaux Mixture and Paris Green 
Bordeaux mixture is primarily a fungicide: but it is also useful 
as a repellent against some insects, and with Paris green or arsenate 
of lead it makes an excellent combination spray to be used when both 
fungi and leaf-eating insects are to be dealt with on the same crop. 
Various strengths of the Bordeaux are used by the vegetable gar- 
dener according to the plants to be sprayed. Those in commonest use 
are often conveniently designated as 4-4-50, and 6-6-50. The sig- 
nificance of the figures is evident from the following 4-4-50 
formula : 
Copper sulphate 4 pounds 
Quicklime 4 pounds 
Water 50 gallons 
For such plants as asparagus, tomatoes, and melons, the 4-4-.SO 
strength is used ; and for the potato and related plants, the 6-6-50. 
*Milk of lime is made by slaking stone lime and adding sufficient water to 
make a thin whitewash.
