Spraying vegetables is simply carry.

Paris Green Spray-Paris green
spray for insects is made as fol
lows: 1 pound quick lime and zoo
gallons of water. Make the Paris
| green into a paste with water before

pound of Paris green is the amount
| to be used.
Paris green is a dust for insects.
One pound Paris green mixed with
S to 20 pounds of flour or air Stacked
| lime may be applied as a dust.
Resin Wash-(Used to make arse
nate of lead adhere to the plant:
2 pounds resin
/ pound crystalized sal-soda
2 quarts water.
Boil until a clear brown solution
is obtained. Use one-siXth of a
pint to so gallons of spray material.
Bordeaux Mixture-This is a
fungicide of exceptional value for
general use, although in late years
it has been supplanted by the sum-
mer strength lime-sulphur solution
for the apple scab and by the self
boiled lime-sulphur for peach spray
ing.
Bluestone copper sulphate, to 5
pounds
Lime, fresh and unslacked, 5 to 6
pounds
Water, SO gallons.
Dissovle the bluestone in 25 gallons
Of water. Since a solution. of blue
stone is heavier than water, the cop
per sulphate should be suspended at
the surface of the water deep enough
to be covered. Slack the lime and
mix with rs gallons Of water. Pour
bluestone solution and the lime solu-
ton at the same time through a
strainer. When a large quantity of
Bordeaux is needed, stock solutions
can be made up, using one pound of
bluestone to a gallon of water and
the same ratio with lime and water.
To improve the spreading and
sticking qualities of Bordeaux mix
ture, it is advisable to dissolve from
two to three cakes Of hard soap in
each SO gallons. rr.
For making small quantities, use
ounce Of bluestone, 2 ounces of
lime and 5 gallons of water.
In a great many instances it may
be more convenient to obtain these
sprays or the material for making
them at a local drug store. If you
wish only a small quantity and if
you are pressed for time, it would
possibly be advisable to buy in this
way. If large quantities are needed
you could obtain them from the
Southern Brokerage company, of
Fort Valley, Ca, or the Graselli
Chemical company, of Birmingham,
Ala.
