RETORT OF THE STATE ENTOMOLOGIST I905

containing the lime, adding at once enough to make 9 gallons of 

 boiling water. It was found necessary to add 2 gallons more or 

 the material would have been dry before the reaction stopped. The 

 latter was very violent, and after being covered and standing 30 

 minutes was a bright orange. There was about I quart of sedi- 

 ment. This wash was applied March 31 to 18 appletrees in the 

 orchard of Mr McCoun at Oyster Bay. April 15 it was seen 

 that the first two trees were well covered except in the case of a 

 few twigs. The spray was moderately thick on these and on those 

 treated with only one application the color was lead-gray, the 

 application being thin and more twigs missed. There was no 

 appreciable washing. July 11 the wash was still apparent on the 

 first tree and there was very little breeding in spite of the scale 

 being so abundant the previous season as to kill many limbs. Sep- 

 tember 26 there was a limited amount of breeding. 



Another lot of this wash was prepared April 7 and applied to 

 17 appletrees in the orchard of Mr Shons at Washingtonville. 

 The reaction was very violent and over in seven minutes. There 

 was a large amount of sediment, probably 4 quarts. The wash did 

 not spray well. An examination April 14 showed that the first 

 tree was well covered in places, only one limb apparently escaping 

 treatment. There were no signs of washing. July 13 very 

 little breeding was evident except on the third tree where there was 

 considerable on a badly infested limb which was probably skipped 

 in part. September 28 there was very little breeding as a rule. 



Formula 6 



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

 sulfur to 50 gallons of water differs only from formulas 1 and 2 

 in calling for equal amounts of lime and sulfur. One lot was 

 prepared April 7 and applied to six Ben Davis trees in the apple 

 orchard of Mr Shons at Washingtonville. It was boiled 30 

 minutes, at the end of which time it was an orange-red color. An 

 examination April 14 showed that the first tree was well covered 

 and the others moderately so, with some twigs skipped. The wash 

 adheres very well even on the twigs. July 13 there was very little 

 or no breeding and the wash was quite evident. September 28 

 there was very little breeding and the results were generally very 

 satisfactory. 



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

 23 Bartlett pcartrees in the orchard of Mr McCoun at Oyster Bay.
