2. The first application of a funpcide should be made early, no 

 later than Immediately after the petals fall; an application made 

 just before the buds oix^n would ])it)l)ably be of value. (Page 365.) 



3. The time for combating the apple-woi-m is inmiediutely after 

 the petals fall, and the treatment should be repeated once or twice 

 until the ap}>los begin to hang down. (Page 303.) 



4. Apple-ti-ees should be pruned so that all parUi may eav<iily 

 be reached by a spray; well pruned trees allow free access of light 

 and air among their branches, which prevents fungi from obtain- 

 ing so strong a foothold. (Page 3(53.) 



5. The injury done by the apple-scab fimgus was decidedly 

 reduced where the Bordeaux mixture was used. (Page 367.) 



6. "VMien Paris green was added to the Bordeaux mixture the 

 fungicidal action of the combination was more marfced than when 

 London pui^ile was u§ed in place of Paris green. (Page 367.) 



7. Paris green has a certain fungicidal value, but in this re«i)ect 

 it does not nearly equal the Bordeaux mixture. (Page 367.) 



8. The value of Paris green a® an insecticide does not appear 

 to be materially affected whether it is applied alone or in combina- 

 tion with the Bordeaux mixture. (Page 3G8.) 



9. The insecticide value of Paris green when used with the 

 Bordeaux mixture was greater than that of London purple when 

 similarly applied. (Page 367.) 



10. Moi-e applications ai-e required during a wet season than 

 during a dry one; during wet weather they should be repeat^ed 

 every seven to ten days. (Page 3(55.) 



11. The results obtained this season from the application of a 

 combination of the Bordeaux mixture and Paris green or London 

 purple show that the use of such a combination is valuable and 

 practicable for the treatment of the apple-scab fungus and the 

 apple-worm, even in a wet season. 



12. The apple scab is found in all regions in the United States 

 from which reports have been obtained. 



13. It is probable that none of our commonly cultivated apples 

 are in all seasons free from scab. 



14. Some varieties are much more subject to the disease than 

 others.
