Diseases of Apples and Pears. 

 Apple Scab: Dormant sprays are of 

 no value against scab. In Western Ore- 

 gon with the more susceptible varieties 

 the delayed dormant spray (No. 2) must 

 be given as the first scab spray to pre- 

 vent early infections. At least four 

 scab sprays are required to insure a 

 clean crop where rains continue into 

 June. 



Lime-sulphur will burn through scab 

 spots which are already present on the 

 leaves, and not infrequently also will 

 cause a slight edging and tip burn of 

 healthy leaves; but this is unavoidable. 

 Periods of hot weather, however, are 

 conducive to fruit burn and to more se- 

 vere foliage injury. At such times the 

 use of self-boiled lime-sulphur is sug- 

 gested. 



Pear Scab: This disease, which is 

 similar to apple scab, is controlled in 

 the same way. At least two thorough 

 sprays before blossoming must be given 

 to catch early infections. Some varie- 

 ties, however, are extremely susceptible 

 to lime-sulphur injury and very weak 

 dilutions of this material are suggested. 

 In fast, on the sorts most liable to spray 

 injury, the use of self-boiled lime-sul- 

 phur beginning with the calyx spray- 

 would be advisable. The addition of a 

 spreader to this material will greatly 

 increase its covering power. 



Fire Blight: While scab may destroy 

 an entire crop, fire blight may destroy 

 the entire orchard. It is the most 

 dangerous of all known diseases of the 

 apple and pear, and must be watched 

 for unceasingly. 



In cases of suspected fire blight, send 

 specimens at once to the Agricultural 

 Experiment Station at Corvallis for 

 microscopic examination, and get in 

 touch with your county fruit inspector 

 or Farm Bureau agent. Do not attempt 

 to cut out blight until you have received 

 careful directions from a reliable source. 

 It is highly contagious and may easily 

 be spread by persons who do not under- 

 stand the disinfecting process. 



Do not be duped into using so-called 

 blight cures. Many orchards have been 

 ruined because owners have unwisely 

 put their trust in some reputed "expert" 

 or in some alleged "remedy" backed up 

 by fine testimonials. 



Apple Tree Anthracnose: Infections 

 on fruit and branches start in the fall 

 during the rainy spells. To clean up a 

 badly attacked orchard an application 

 of weak Bordeaux mixture should be 

 given in August or early September, 

 followed by winter strength Bordeaux 

 immediately after picking time. When 

 well under control, a single thorough 

 spraying just after picking season will 

 often be sufficient to keep the disease 

 within bounds. 



Powdery Mildew of Apples: Prune 

 out all affected tips before spring. The 

 ordinary sprays for the control of scab 

 when given according to schedule will 

 keep the mildew down to a practically 

 negligible amount. The special iron 

 sulphide mixture formerly advised is 

 probably not of great advantage under 

 Oregon conditions. 



Moss: Moss is rarely troublesome 

 where a regular spray schedule is main-
