ANNUAL REPORT OF THE 



Off. Doc. 



Ou the stone fruits we used only one quart of strong lime-sulfur 

 solution in forty gallons of water, adding the arsenate in the pro- 

 portion mentioned above. For suctorial insects, such as the Red 

 bug, young scale insects, plant lice, leaf hoppers and other suctorial 

 insects, we used one ounce of commercial tobacco decoction, and one- 

 quarter pound of soap in five gallons of water. We found also that 

 by spraying apple trees just after the green tips of the leaves com- 

 mence to show on the buds, using the strong lime-sulfur solution, 

 we killed the apple aphids which had then hatched. For the very best 

 possible results we recommend an extra fungicidal spraying, espec- 

 ially for apple scab, about the time the blossom clusters are separat- 

 ing, but before the petals open, and another about the latter part of 

 July, which is about time for spraying for the second brood of the 

 Codling moth. 



There has been no one feature contributing so greatly to the speedy 

 improvement and quality of Pennsylvania fruit as the work in the 

 Demonstration Orchards. Buyers of fruit sought these orchards 

 for fruit which was properly treated, and hence they knew it was 

 good. In some places they bought only the sprayed fruits, and 

 would not even look at the fruits in unsprayed orchards. 



(3) SUPERVISION ORCHARDS 



The call for service in the Demonstration Orchards was so great 

 that it was quite impossible to reach all of them; hence, to give in- 

 dividual service we found it necessary to maintain a supervision 

 system of orchard management by which we went to the premises 

 and spent at least a day with the owner showing him how to pro- 

 ceed, and going over the entire subject of his orchard, writing out a 

 plan of management for the year, leaving a copy of the same with 

 him and sending another copy to this office for filing and observation. 

 During the year service was given in 1051 Supervision Orchards dis- 

 tributed in different counties in Pennsylvania, as follows:
