PREPARATION OF INSECTICIDES AND FUNGICIDES 
INSECTICIDES 
(To destroy insects that feed on plant tissue) 
Arsenate of Lead. Use 3 Ibs. to 50 gals. of water. 
(To destroy insects that suck the sap of plants) 
Kerosene Emulsion. Dissolve '/% Ib. hard soap in 1 gal. of water 
(preferably soft water) and while still boiling hot, remove 
from the fire and add 2 gals. of kerosene. Stir the mixture 
violently by driving it through a force pump back into the 
vessel, until it becomes a creamy mass that will not separate. 
This requires from 5 to 10 minutes. It is ready to be diluted 
with water and applied. For hard-bodied insects, like the 
chinch bug, use | part emulsion to 8 or 10 parts water. For 
plant lice, etc., 1 part emulsion to 15 parts water. 
Whale Oil Soap. On foliage use at the rate of | Ib. to 4 gals. 
of water; in winter 2 Ibs. to 1 gal. of water. 
Lime and Sulfur Wash. (For San Jose scale and other scale 
insects). Winter treatment: slack 50 Ibs. stone lime in a 
little hot water, gradually add 50 Ibs. of ground sulfur and 
stir vigorously; boil 1 hour, strain, dilute with water to make 
150 gals. of wash and apply. It corrodes brass and copper 
and if a pump with brass fittings is used, care should be 
taken to run clear water through it after each day’s spraying. 
Never boil the wash in a copper kettle. 
FUNGICIDES 
(To destroy spores of plant diseases) 
Bordeaux Mixture. Slack 4 Ibs. of stone lime in a small quan- 
tity of water and when completely slackened add more water 
and mix thoroughly. Dissolve 5 Ibs. of copper sulfate by 
placing it in a coarse bag suspended in water. Dilute each 
with water and pour them into the spray tank simultaneously, 
taking care to strain the lime solution before doing so. Add 
water to make 50 gals., stir vigorously and use to spray. 
Ammoniacal Carbonate of Copper. Dissolve 6 ozs. of copper 
carbonate in 3 parts of ammonia and add water to make 
50 gals. As the ammonia is of variable strength, only enough 
should be used to dissolve all the copper carbonate.
