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; *4 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 pears, 1 gallon to 50 gallons water. 
Price—1 qt., 35c; Vi gal., 50c; 1 gal., 65c; 5 gals., $2.25; 10 gals., $4.00; 15 gals., $5.45; 25 gals., $6.00; 
50-gal. bbl., $8.50. Post paid—1 qt., 50c; 44 gal., 65c; 1 gal., 85c. 
BLUESTONE-COPPER SULPHATE—(Formula for Making Home Made Bordeaux.) In case you wish 
to use Bluestone and Lime to make your Bordeaux, proceed as follows: Dissolve our Snowform 
(Powdered) Bluestone at the rate of 4 pounds to 50 gallons of water. It will require only a few min¬ 
utes stirring to dissolve Snowform Powdered Bluestone. Then while stirring add 6 pounds hydrated 
lime to the above mixture. If the above directions are correctly followed you will have 50 gallons of 
standard strength 4-4-50 Bordeaux. In case you need a 3-4-50 strength, use only 3 pounds of the 
Snowform Bluestone, and if you wish a 5-4-50 strength, use 5 pounds of the Snowform Bluestone, but 
do not change the other ingredients. By combining the Bluestone and the Lime at different propor¬ 
tions, one can make any strength Bordeaux Mixture desired. Bluestone is used either alone or in 
combination with other material to spray peaches when dormant, and apples, grapes and pecans dur¬ 
ing summer. Bluestone is also used in spraying potato storage houses—use 1 pound to 5 gallons water.

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 mate¬ 
rials 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., 65c; 5 lbs., $1.35; 10 lbs., $2.25; 25 lbs., $5.50. Not

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, Paris Green, and Lime Sulphur and with combinations of these sprays. 
Use 2 heaping tablespoonfuls for each 5 gallons spray; 1 pound for 50 gallons.

ZINC SULPHATE—Peach 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 314 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. 
Full directions with each package. Price—Post paid—1 lb., 25c; 5 lbs., 70c; 
10 lbs., $1.15; 25 lbs., $2.25; 50 lbs., $3.75. Not Prepaid—1 lb., 15c; 5 lbs., 50c; 
10 lbs., 90c; 25 lbs., $1.75; 50 lbs., $3.00; 100 lbs., $5.25. 
DRITOMIC SULPHUR— (Peach Dritomic or Apple Dritomic)—It is a spring and summer spray, safe to apply to fruit and foliage 
where older type materials would develop caustic tendencies. The universality of its use, right through the growing season, is 
ample evidence. Its fineness enables it to go into suspension easily, and without sediment. You have no annoying loss of time to 
clean clogged spray nozzles. Dritomic Sulphur is an excellent preventive for all fungous troubles, bitter, brown rot, scab, etc. 
We can furnish Peach Dritomic or Apple Dritomic. When ordering specify the one desired. 
Post paid—4 lbs., 75c; 8 lbs., $1.40; 24 lbs., $2.90; 48 lbs., $5.50. At Store—4 lbs., 60c; 8 lbs., $1.15; 24 lbs., $2.50; 48 lbs., $4.75; 96 lbs., $9.00
