PROCEEDINGS OF THIRTY-SIXTH FRUIT-GROWERS ' CONVENTION. 



121 



THIRD DAY. 



TYatsoxville. Cal., December 9, 1909. 



The convention was called to order at 9.30 a. m. by President Jeffrey. 



PRESIDENT JEFFREY. Now. Mr. W. H. Volek, one of your 

 honored citizens, will present " Insect Pests and Diseases of the Apple." 

 (Applause.) 



MR. VOLCK. With regard to this subject of "Insect Pests and 

 Diseases of the Apple," it is a very broad one, and a paper to be pre- 

 sented and read before this convention must necessarily be of limited 

 length; so. in order to make the matter in this paper more clear and 

 perhaps take it up more thoroughly for those who are most interested, 

 I have distributed around in the book racks of these seats two bulletins. 

 You will find one in the other, and the outer bulletin, called "Winter 

 Control of Orchard Pests." is just from the press, and this edition of 

 500 copies was made for the benefit of the State Fruit Growers' Con- 

 vention, and we hope that it will take all of these bulletins. There 

 rnay not be enough people in the audience to take them all individually, 

 but you may have friends that you can distribute them to. and we 

 would like to see that these bulletins go out, because they show in a 

 concise manner all the work that has been done here, and they will 

 make the matter in the paper more clear. These bulletins, I may add, 

 are published at the expense of Santa Cruz and Monterey counties, 

 which have heretofore supported this investigation, and in sending out 

 a county publication broadcast over the State we feel that we are not 

 advertising Santa Cruz and Monterey counties as a land of pests, partic- 

 ularly, but as a place where they know something about how to get the 

 better of such troubles. 



INSECT PESTS AND DISEASES OF THE APPLE. 



By W. H. Volck of Watsonville. 



The subject of insect pests and diseases of the apple is rather a 

 broad one, and perhaps the best method of approach is to take a hypo- 

 thetical orchard and carry it through the year. The necessities of this 

 orchard in the way of treatment for diseases will vary with the locality, 

 but there are certain general methods of procedure applying to all. 

 Also, in California the great bulk of the apples are produced in the 

 central and northern coast counties, well within the limits of the ocean 

 influence. The Pajaro Valley is the center of this production, and in 

 point of quantity California apples may be considered as the special 

 crop of this locality. 



Other districts produce apples, but as yet to a quite limited extent. 

 The mountain sections have been developed slightly, and produce a 

 type of fruit quite distinct from the coast. In the higher altitudes, 

 free from fog, the growth of the trees is also different, and there is
