6 Report of State Board of Horticulture. 



inspectors. It is only necessary for you to visit the fruit 

 markets of Portland to be convinced of the salutary effects 

 of this legislation. The scaly, worm-eaten, fungus-covered 

 fruit, much of it not grown in Oregon, has disappeared, and 

 in its place you will find the clean, sound, healthy product. 

 Prices have advanced greatly to the satisfaction of the careful 

 orchardist, while the slovenly grower has been taught the 

 lesson that he must raise clean fruit or seek some other 

 calling. , 



It is a matter of the greatest importance that you recom- 

 mend for appointment for county inspectors experienced fruit 

 growers of conservative judgment, and that the expenses of 

 such inspectors in their respective counties are limited to the 

 lowest amount consistent with efficiency, in order that the 

 county inspectors law may meet with popular approval. 



INSECT ENEMIES. 



The codling moth and San Jose, or pernicious, scale, con- 

 tinue to ravage our orchards, causing in the aggregate im- 

 mense loss. At a meeting of the Hood River fruit growers last 

 spring, I recommended the arsenate of lead for codlin moth 

 and all insects that chew leaf or fruit, in lieu of other arseni- 

 cal poisons. Over 2,000 pounds of Swift's arsenate of lead 

 was used at Hood River, at the rate of two and one-half 

 pounds of the poison to fifty gallons of water, with most sat- 

 isfactory results. In some instances there were not more 

 than 1 per cent of wormy apples with five sprayings. Its ad- 

 vantages over any combination of lime and arsenic are indeed 

 many, and I do not hesitate to recommend its use to the fruit 

 growers of our State. So numerous were the inquiries in 

 regard to this insecticide that I prepared a circular letter^ 

 which I beg leave to incorporate herewith. 



Hood River, Oregon, , 1905. 



Dear Sir: — I am in receipt of your inquiry relative to the use of 

 arsenate of lead as a spraying material for the codlin moth, and other 

 chewing insects. The formula for making the arsenate is as follows : 

 4 oz. arsenate of soda, 

 12 oz. acetate of lead. 



Dissolve in water in separate buckets, pour together, and you have 

 sufficient arsenate of lead for fifty gallons of watex-, and all you need
