Another lot of this wash was prepared April 5 and applied to 

 nine Ben Davis appletrees in the orchard of Mr Shons at Washing- 

 tonville. The water in this case was not boiling hot and there was 

 consequently very little reaction, so slight that it was not regarded 

 as having been sufficiently cooked. Steam was therefore turned 

 on and the preparation boiled for 10 minutes, at the end of which 

 time it was orange-red. Rain interfered with the application and 

 continued all night. The sprayed trees showed some signs of 

 washing though the insecticide was visible upon all. April 14 a 

 close examination showed that there was a little even on apparently 

 bare spots. The wash adheres well to the twigs. July 13 the wash 

 was evident and there was as a rule very little breeding. Some 

 of the fruit was slightly spotted, due probably to portions of twigs 

 being skipped. September 28 there was not much breeding though 

 there was a little more than on the adjacent row in this orchard, 

 sprayed with formula 1. 



Another lot of this wash was made up March 30 -and applied to 

 22 Bartlett peartrees in the orchard of Mr McCoun at Oyster Bay. 

 The reaction was very satisfactory, it being necessary to add some 

 cold water in order to prevent the wash from boiling over. The 

 color was very satisfactory, ranging from orange to orange-red. 

 An examination April 15 showed that the lower branches of the 

 first three trees were fairly well sprayed. The application was 

 thick and there were no signs of washing. July 11 breeding was 

 rather abundant and it was continued September 26. The abund- 

 ance of young in this instance may be accounted for largely by the 

 untreated upper portions of the trees. 



Another lot was prepared April 5 and applied to 17 peachtrees 

 in the orchard of Mr Shons at Washingtonville. The reaction was 

 very active and lasted but five minutes, producing an orange-red 

 color. An examination April 14 showed that many portions of 

 the limbs were skipped and that the wash adhered well even on the 

 twigs. There was very little breeding evident July 13 and the same 

 was true September 28. 



Formula 5 



This wash, composed of 30 pounds of lime and 15 pounds of 

 sulfur to 50 gallons of water depends upon the heat generated by 

 the slaking lime to bring about a combination between the lime 

 and sulfur. The latter was first made up with about 2 gallons of 

 boiling hot water in a barrel and this was then stirred into the barrel
