REPORT OF THE STATE ENTOMOLOGIST I905 



8l 



pump, as there was some difficulty in operating it. Examination 

 April 15 showed that the tops of most of the trees were skipped, 

 while the lower portions were fairly well covered. There was very 

 little breeding July II, and September 26 young were more abun- 

 dant and on some trees there was considerable breeding, clue 

 probably to the trees not being thoroughly covered. 



Another lot was applied April 4 to 17 peachtrees in the orchard 

 of Mr Shons at Washingtonvillc. The preparation of the wash 

 gave the usual reaction except that a wine-red color was obtained. 

 An examination April T4 showed that tree 1 was fairly though rather 

 thinly covered. There was no evidence of washing. July 13 there 

 was very little or no breeding and the wash was still evident and on 

 September 28 there was very little breeding. 



Formula 2 



This wash, composed of 25 pounds of lime and 20 pounds of 

 sulfur to 50 gallons of water differs only from formula 1 in calling 

 for a larger amount of lime and sulfur. The method of preparation 

 in both instances was identical. The first lot was made with lime 

 from the bottom of a barrel, and as the action was very slow an 

 .additional 2 pounds was added about two minutes later. This 

 increased the chemical action and continued it much longer. The 

 wash was a deep red in 20 minutes and eventually became a deep 

 green. There was less than a quart of sediment. It was applied 

 March 30 to 15 appletrees in the orchard of Mr McCoun at Oyster 

 Bay. An examination April 15 showed that the first four trees 

 were well covered except for a few twigs that were missed and 

 that more were skipped where there was but one application. The 

 former trees were well and the latter thinly covered. July 1 1 the 

 wash was visible to some extent and there was a little more breed- 

 ing on near-by trees treated with formula I. September 26 there 

 was some breeding though none of the trees were in a bad condition. 



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

 seven greening trees in* the apple orchard of Mr Shons at Washing- 

 tonville. This lot was boiled 30 minutes and stood as long, becom- 

 ing at the end of this period a pea-green color. An examination 

 April 14 showed that the application was only fair, limbs being 

 skipped in places even on the first tree. The insecticide adhered 

 well to the twigs and there was no evidence of washing. July 11 

 the wash was easily seen and there was very little or no breeding. 

 September 28 very few young were to be found.
