SPRAY CALENDAR. 



i6i 



iug use warm water. These are the stock 

 solutions. Each gallon of milk of lime con- 

 tains one pound of lime, and each gallon of 

 bluestone contains one pound of bluestone. 

 When we wish to make up a barrel of Bor- 

 deaux mixture we take out 4 gallons of milk 

 of lime and 4 gallons of bluestone solution, 

 and either dilute each in separate barrels in 

 20 gallons of water before mixing in the bar- 

 rel attached to the spray-pump, or else pour 

 each separately into the barrel in which are 

 already ^2 gallons of water. The first 

 method is the preferable one. 2. Never 

 mix the concentrated stock solutions to- 

 gether. If the milk of lime and bluestone 

 are mixed in the concentrated form, just as 

 they are taken from. the stock solution, a pre- 

 cipitate of a flakey nature will soon settle 

 out, and either fall to the bottom or clog the 

 nozzle. 3. Test the Bordeaux to find out 

 whether sufficient milk of lime has been 

 added. This is most easily done by means 

 of the ferrocyanide test. A saturated solu- 

 tion of this substance can be purchased at 

 any druggist's for a few cents. In testing, 

 place some of the Bordeaux, which has been 

 thoroughly stirred, into a saucer, and add 

 a few drops of the ferrocyanide. If suffi- 

 cient lime has been used, no discoloration 

 will appear, but if insufficient, a deep bark 

 brown color will be produced. 4. Always 

 strain the milk of lime to prevent gritty par- 

 ticles from clogging the nozzles. 5. Use a 

 fine nozzle ; do not soak or drench the tree. 

 6. The stock solutions will keep, but the 

 Bordeaux mixture becomes useless after 

 standing for a day or two. 



2. The Combination Bordeaux and 

 Paris Green Mixture — (For Fungous 

 Diseases and Leaf -Eating Insects). This 

 mixture is prepared like the Bordeaux, but 

 4 ounces of Paris green are added and thor- 

 oughly stirred before spraying. Copper sul- 

 phate (bluestone). 4 lbs. ; quick lime (fresh), 

 4 lbs. ; Paris green, 4 oz. ; water (i barrel), 

 40 gallons. In. small quantities it may be 



made as follows : Bluestone, 4 level table- 

 spoonfuls; quick lime, 4 level tablespoon- 

 fuls ; Paris green, i level tablespoonful ; 

 water, i pail (2 gallons).

 charlock or Herrick in grain fields. Copper 

 sulphate, 9 lbs.; water (i barrel), 45 gal- 

 lons. This quantity is sufficient for an acre. 



4. Ammoniacal Copper Carbonate So- 

 lution. — Copper carbonate, i oz. ; strong 

 ammonia sufficient to dissolve the copper 

 carbonate, usually more than 3^ pint ; water, 

 10 gallons. This solution is not much used, 

 and is recommended only in cases where the 

 fruit is so far advanced that it would be dis- 

 figured by using the Bordeaux mixture.

 phur) . Used to control gooseberry mildew. 

 Dissolve 4 oz. in 8 gallons of water.
