Report of State Board of Horticulture. 37 



recently in regard to the best methods for wiutcr spraying and 

 it is expected there will be more of such spraying done this 

 Avinter than ever before. Not enough attention, however, is 

 being paid to the apple-tree anthracnose, for I visited several 

 orchards during the summer in which it had done great 

 ■damage. The best method of treatment seems to be to give 

 the trees a thorough spraying with bordeaux mixture early in 

 the fall to prevent the growth of the spores and to cut out new 

 spots which may have started. 



The greatest difficulty in connection with the enforcement of 

 the law in regard to infested orchards, is encountered in securing 

 the proper spraying or destruction of infested trees in small 

 home orchards and city lots. Owners of such trees are often 

 too careless, their spraying being ineffective and the amount 

 of time required to supervise the work on a large number of 

 places renders it almost impossible to secure thorough work 

 by those not interested. A large number of nqtices to spray 

 were sent out or served personally and iu a majority of cases 

 the trees indicated were sprayed, but too often the work was 

 so poorly done as to require treatment again tliis 3''ear, or the 

 destruction of the trees, which plan would probably be best for 

 all interested. In nearly all cases where commercial orchards 

 were found infested with scale insects or other pests, the own- 

 ers have been ready to follow the directions given in the spray 

 bulletin, and will continue to give their attention to any trees 

 that may become infected. The complete eradication of tlie 

 scale iu all districts is doubtful, as it is often found on wild 

 shrubs, but by the co-operation of all fruit growers, whose 

 orchards may become infected, its ravages may be reduced to 

 the minimum. 



The San Jose scale is very destructive to the mountain ash 

 and may be found on these trees in nearly every town in 

 Western Oregon. From these trees it is carried to fruit trees 

 by birds which gather to feed on the red berries. For this 

 reason persons owning mountain ash trees should see that 

 their trees are sprayed each winter with the lime, sulphur and 

 salt spray. In this connection I wish to urge that tlie board 

 should make some special provision for the enforcement of the 

 law in the larger towns and cities, as it is here that the worst 

 infected trees are found. If, however, the commissioner of a 

 district devotes the necessary time to these cases very little 

 other work could be done. 



The soil and climate of the Willamette Valley seem particu-
