Therefore, there are two general classes of sprays, insec- 
ticides and fungicides, and the insecticides being divided into 
two classes known as poison and contact insecticides. Ar- 
‘senate of Lead is a good example of the poison insecticide, 
while Lime-Sulphur Solution is a good example of the contact 
insecticide, with Bordeau Mixture being the old stand-by as a 
funaicide. 
ae SPRAY FORMULAS 
Arsenate of Lead. One of the most common and most | 
valuable poison sprays; may be prepared at home, using 
either powder or paste, it being easily procured in either 
form. Use at the rate of 2'/ pounds of the paste or 2 
pounds of powder to 50 gallons of water. Use for the 
control of flea beetle on grape, caterpillar on pecan, biting 
and chewing insects on shade trees, shrubs, etc., and for 
tent caterpillar on evergreens. Also use as spray for cur- 
culio and codling moth on fruit trees. 
Nicotine Solution. This may be bought in concentrated 
form at almost any drugstore, usually under the name of 
"Black Leaf 40."". In large quantities, use approximately 34 
pint to 100 gallons of water, or in small quantities, use about 
| ounce to 8 gallons of water. In making the spray mix 
the nicotine with very heavy suds, using lye soap or strong 
laundry soap for the suds, as this will cause the spray to 
adhere and spread much better. This is very easily pre- 
pared at home and is an excellent spray for control of aphis — 
on apple, plum, roses, etc., and for use in ridding plants of 
red spider. ie ie . 
Lime-Sulphur Solution. One of the most important con- 
tact sprays we have, being one of the most effective for 
treatment for San Jose scale while trees are dormant. If 
commercial Lime-Sulphur is used, it should be used 2 pounds 
to 8 to. 10 gallons of water for the winter spraying, while 
for summer the dilution should be approximately | pound 
to 8 or 10 gallons of water. This spray is excellent for use 
while trees are dormant as it helps to keep them in healthy - 
state and is particularly beneficial in the control of scale. 
Bordeau Mixture. This is easily secured in prepared form 
at almost any drugstore, and usually directions for prepara- 
tion and dilution are given. This is particularly useful in 
control of mildew and all fungus diseases, such as brown rot 
on peach and apple, black rot in grape, or mildew on roses, 
etc. 
All of these sprays may be used by the homeowner, ap- 
_ plying with large sprayer in orchard or vineyard where neces- 
sary, or knapsack sprayer for use where only a few trees 
need treatment, or even a small hand sprayer for use on 
small plants around the home. A small investment in equip- 
ment and materials may mean many dollars to you in your 
orchard or beauty to you in your home grounds.
