SPRAYING . 
Spraying has come to be an established part of fruit growing. With all 
that has been written on the subject, the fruit grower should be competent to 
perform the ordinary spraying of his trees without further advice; but for the 
benefit of those who may not be familiar with the best methods and practice, 
we give the following from the last report of the State Board of Horticulture: 
Requisites for Successful Spraying. 
Materials of standard strength, carefully compounded applied in thorough 
manner at regular intervals. Fruit thinned so that, the spray liquid can reach 
every portion of that remaining on the tree. 
Insecticides. 
Used for codlin moth larvae, caterpillars, slugs, and all biting and chewing 
insects. 
SPRAY NO. 1— ARSENATE OF LEAD. 
For codlin moth and all other chewing insects. The formula for making 
the arsenate is as follows: 
4 ounces arsenate of soda. 
12 ounces acetate of lead. 
Dissolve in water in separte buckets, pour together, and you have suffi- 
cient arsenate of lead for 50 gallons of water, and all you have to do is to 
pour your arsenate into the water and stir well. Its advantages over other 
forms of arsenate are as follows: 
First — It remains in suspension longer than any other arsenical spray, and 
hence requires but little agitation. 
Second — It is very adhesive, but little affected by rains, and therefore 
requires a less number of applications. 
Third — It is more pleasant to handle, and can be used any strength with- 
out injury to the foliage. 
The arsenate of lead has been highly endorsed by the University of Cali- 
fornia, Professor Steadman, entomologist of the State of Missouri, Professor 
Gillette of Colorado, and many other authorities. In Colorado but three spray- 
ings were used, with excellent results. Professor Steadman recommends four: 
(1) when petals fall, (2) two weeks later, (3) 30 days after the second, and 4 
30 days still later. If used with bordeaux, use only one-third of the arsenate. 
The Merrimac Chemical Co. of Boston sends out a paste form of the arsen- 
ate of lead, known as “Swift’s Arsenate of Lead;’’ and the Bowker Insecticide 
Co., of New York, a similar preparation known as “Disparine,’’ and both have 
given excellent results. It might be better to use one of these when only a 
small amount is required, and 2 % pounds of either will be sufficient for 50 
gallons of water, in which they dissolve readily. They sell for about 15 cents 
per pound in 100 pound kegs, and can be had from the local dealers. 
A considerable amount of the arsenate of lead w r as used the past season 
at Hood River and Southern Oregon with most satisfactory results, and its 
use will become quite general the coming season.
