A few years ago, when the U. S. Department of Agriculture developed the formula for Oil 
Emulsion and made certain claims for it, many good orchardists accepted their recommendations 
and have continued using it, to their entire satisfaction. Most of the more skeptical orchardists have 
since been convinced of its merits, and the use of Oil Emulsion has steadily grown. An Emulsion 
can be made of any oil from coal oil up to the extremely heavy oils, but Oil Emulsion made of the 
light and low grade oils will not control scale and will frequently injure fruit trees. Buchanan’s Oil 
Emulsion is made exactly according to U. S. Government Formula. 
BUCHANAN’S OIL EMULSION — For a dormant spray, Buchanan’s Oil Emulsion provides the 
cheapest, most effective and complete control of scale insects, aphis and thrips that winter over on 
trees. For scale control on all fruit trees, use 1 gallon Oil Emulsion to 24 gallons water, or 2 gallons 
to 48 gallons water for a 50-gallon mixture. If your water is extremely hard, 4 pounds Bordeaux 
added to each 50 gallons of water, before adding the oil, will prevent oil from curdling. To get best 
results, every part of the tree must be completely covered. Spray in fall, after leaves and fruit 
are off, or in spring before buds swell. To control peach leaf curl and scale, combine Buchanan’s 
Oil Emulsion with prepared Bordeaux Mixture or home-made Bordeaux, directions below. 
Price—1 qt., 35c; y 2 gal., 50c; 1 gal., 65c; 5 gals., $2.25; 10 gals., $4.00; 15 gals., $5.45; 25 gals., $7.00; 
50-gal. bbl., $10.00. Post paid—1 qt., 50c; % gal., 65c; 1 gal., 85c. 
LIME SULPHUR SOLUTION—Is an insecticide as well as a fungicide, free from sediment and 
works through the nozzle easily. Used as an insecticide to control San Jose scale, blister mite and 
similar sucking or scale insects, at a dilution of 1 gallon to 8 gallons of water and applied either 
after the leaves drop in the fall or before the buds open in the spring. For small quantities, use 
1 pint Lime Sulphur Solution to 1 gallon of water. Never use at this strength when trees are in 
foliage. The spring application, just before the buds swell, will assist in controlling leaf blister mite, 
plant lice and peach leaf curl and is advisable in orchards when the scale is already under control. 
To control scab, leaf spot and similar fungus diseases on apples and 1 gallon to 50 gallons water. 
Price—1 qt., 35c; % gal.. 50c; 1 gal., 65c; 5 gals., $2.25; 10 gals., $4.00; 15 gals., $5.45; 25 gals., $6.50; 
50-gal. bbl., $9.50. Post paid—1 qt., 50c; V 2 gal., 65c; 1 gal., 85c. 
BLUESTONE - COPPER SULPHATE—(Formula for making Home Made Bordeaux.) By 
proceeding according to the following directions, one can make their Bordeaux Mixture at home 
very cheaply: Dissolve Bluestone at the rate of one pound to each gallon of water. The only way 
Bluestone can be dissolved is by suspending it over a period of hours in a bag so that the bottom of 
the bag extends about 3 inches below the surface of the water. Using any kind of a container, dis¬ 
solve Hydrated Lime at the rate of 1% pounds to each gallon of water. To each 42 gallons of water 
add 4 gallons of the concentrated Bluestone solution. Then, while stirring vigorously, add 4 gallons 
of the concentrated Lime solution. This makes 50 gallons of 4-4-50 strength Bordeaux Mixture. In 
case you need a 3-4-50 strength, use only 3 gallons of the Bluestone solution, and if you wish a 5-4-50 
strength, use 5 gallons of the Bluestone solution, but do not change the other ingredients. By com¬ 
bining the Bluestone and the Lime Water solutions at different proportions, one can make any 
strength Bordeaux Mixture desired. Bordeaux Mixture at the proper strength, in combination with 
Arsenate of Lead, is used to spray grapes and pecans during the entire season. In case you wish to 
avoid the delay of dissolving the Bluestone crystals, you can use the Snowform Bluestone, priced 
below, which will go into solution instantly. Bluestone is also used in spraying potato storage houses 
—use 1 pound to 5 gallons of water.

ORTHO DRY SPREADER (A Spray Depositor) 
ORTHO DRY SPREADER (A Spray Depositor)—During the past several years there has been developed a new type of spreader 
and spray depositor, known as a non-casein, colloidal spreader. By using small amounts of this spreader, an even, heavy protective 
covering is obtained with such materials as Lead Arsenate and other arsenicals, with Bordeaux Mixture, Sulphur Mixture, and 
Lime-Sulphur. It prevents also blotched coloring of fruit at harvest, so common where sprays are applied which give a splotched 
or spotted coverage on the fruit. 
This new type spreader and spray depositor has entirely replaced casein 
spreaders in the Northwest for the past several years, and has decidedly “made 
good” in Eastern fruit districts. Ortho Dry Spreader should be used at the rate 
of % pound to 50 gallons of water. 
Post paid—1 lb., 35c; 2 lbs., 70c; 5 lbs., $1.50; 10 lbs., $2.50; 25 lbs., $5.75. Not 
Prepaid—1 lb., 25c; 5 lbs., $1.25; 10 lbs., $2.20; 25 lbs., $5.00; 50 lbs., $10.00. 
CASEIN SPREADER—Makes the spray spread, makes it stick and makes it 
cover a greater surface. It can be used with Bordeaux Mixture, Arsenate of 
Lead, Faris Green, and Lime Sulphur and with combinations of these sprays. 
Use 2 heaping tablespoonfuls for each 5 gallons of spray, or 1 pound for each 
50 gallons. 
Price—Post paid—1 lb., 35c; 2 lbs., 65c; 5 lbs., $1.40; 10 lbs., $2.25. Not Prepaid— 
1 lb., 25c; 2 lbs., 50c; 5 lbs., $1.15; 10 lbs., $2.00; 25 lbs., $4.60: 50 lbs., $8.50; 100 
lbs., $16.00. 
ZINC SULPHATE—Feach Bacterial Spot has become destructive in practically 
all sections of the South. Zinc Sulphate is the complete control for this disease. 
Use it in each of the summer sprays on peaches, beginning with the petal fall 
spray. Combine our Zinc Sulphate with whatever summer spray you are using 
on your peaches, at the rate of 3 Vz pounds to each 50 gallons. If you are using 
as much as 4 pounds lime to 50 gallons water in your regular material, addi¬ 
tional lime is not necessary; otherwise add 4 pounds lime to each 50 gallons.
