24 Report of State Board of Horticulture . 



In addition, a large amount of blackberries, raspberries, 

 grapes, etc. Total value of commercial crop at a low esti- 

 mate $250,000 ; to them should be added $50,000 for small 

 orchards and a large amount for domestic use, making in all 

 $300,000, the value of crop. Mr. Geer reports that there is 

 a wonderful activity in the sale of fruit lands, and in plant- 

 ing of new orchards in Grand Round Valley and the irrigated 

 portions of Malheur county. 



The Exposition at Charleston, South Carolina, was a repe- 

 tition of our success at Buffalo, our department of horticulture 

 and pomology receiving 34 gold medals, out of a totol of 64, 

 for all Oregon exhibits. 



The edition of Spray Bulletin No. 1 having been exhausted, 

 and the demand constant, I compiled Bulletin No. 2, embody- 

 ing the best experience of our own and other states. The San 

 Jose scale is the most dreaded enemy of our fruit growers and 

 is found on several of our native shrubs as well as in our 

 orchards. ' 



Annual spraying, while trees are dormant, will practically 

 eradicate it unless in vicinity of native shrubbery infested 

 with it. The formula generally used is known as the " lime, 

 sulphur and salt" remedy. The sulphur and the lime are 

 the effective agents in this compound, so far as killing the 

 scale is concerned ; the salt simply rendering the mixture 

 more adhesive. In Bulletin No. 2, formula No. 4, I have 

 reduced the amount of salt one half. Since compiling this 

 bulletin I liave been convinced that it will be better to leave 

 out all the salt and substitute 4 pounds of bluestone (sulphate 

 of copper) to 150 gallons of the spray mixture. This will 

 serve a double purpose (as fungicide as well as insecticide), 

 and I recommend its general use as the most approved remedy 

 for the scale and fungus spores. Professor Foster, entomolo- 

 gist of the State of Illinois, lias made thorough tests as to the 

 relative efficiency of these two sprays. Living scales were 

 counted in several trees, and the two sprays applied on the 

 same day. It was found the spray containing the sulphate 

 of copper not only destroyed a greater percentage of scales, 

 but that it was also less injured by rains, and that its full 

 effects were reached in five days. 



Anthracnose, or as it is more generally known " dead spot " 

 or "apple canker," is a dreaded fungous disease, in many 

 instances destroying entire orchards. Commissioner Carson's
