BUCHANAN’S INSECTICIDES 
Insecticides are for controlling insects and diseases of fruits 
and vegetables and should be handled with care. When not 
in use put out of the reach of children and pets. 
Post Paid Prices on This Page Through Third Zone Only. 
An Emulsion can be made of any oil from coal oil up to the extremely heavy oils, but Oil Emul- 
sion 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. D. A. Formula, using heavy 
oil. 

INTERNAL USE 
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 at the rate of 1 gallon Oil Emulsion to 24 gallons 
water, slightly more if scale infestation is heavy. If your water is extremely hard, 4 pounds Bor- 
deaux 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 
under Bluestone below. 
Price—1 qt., 35c; 1%4 gal., 50c; 1 gal., 65c; 5 gals., $2.25; 10 gals., $4.00; 15 gals., $5.25; 30 gals., $7.80;

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 quan- 
tities, 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. For early spring and summer spraying. To control scab, leaf spot and sim- 
ilar fungus diseases on apples and pears, 1 gallon to 50 gallons water.

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 Snow- 
form (Powdered) Bluestone at the rate of 4 pounds to 50 reas of water. It will require only 
a few minutes 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 proportions, one can make any strength Bordeaux Mixture desired. 
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 materials 
as Lead Arsenate and other arsenicals, with Bordeaux Mixture, Sulphur 
Mixture, and Lime-Sulphur. 
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. Use at the rate of 1% pound to 50 
gallons of water. g

SOY BEAN FLOUR SPREADER—A most excellent spreader and sticker 
produced by the farmer. Compatible with all summer sprays. Being a 
vegetable product it does not change the spray material chemically in the 
least. The most economical spreader and sticker developed to date and has 
no superior. Orchardists have not used a spreader consistently in the past, 
but now there is no reason to leave out this valuable asset to the spray 
program. It prevents excessive run off of the material you want to remain 
on the fruit and leaves, giving a uniform, even, heavy film of the fungicides 
and insecticides at almost no cost. Use % pound per 50 gallons of spray.
