594 NEW JERSEY STATE AGRICULTURAL. 



5, "Con. Sol," 1 to 40; 6, remainder of orchard, sprayed August 16th with 

 "Con. Sol.," 1 to 40, is much the worst of the lot. 



2. Everything really needs respraying and all the trees except those 

 sprayed August IGth were actually re-sprayed with the "Con. Sol," 1 to 40. 

 In all 164 trees were sprayed and 175 gallons of the mixture were used. 



3. Trees 391 to 463, first sprayed at last visit, have the foliage mottled 

 and show quite a little burning. There were a few dead scales on the 

 trees; but heaps Qf living oneg. Th^re is a general and heavy scattering 

 of white sets and crawling larvae — more of the latter than of the former. 

 Trees 250 to 301, re-sprayed August 16th, have the foliage very distinctly 

 mottled and somewhat scalded. There were a great many dead scales on 

 the trees; but also plenty of living ones. There is a general and rather 

 dense scattering of larvae and recent sets. 



4. The cleanest trees in the orchard are 1, 2, 3, 4, 5 and 10 and group 

 200 to 249 (potassium sulphide) ; but if the scales now on the trees are 

 allowed to continue the trees are sure to be well infested. 



Matters were left then, until I saw the orchard October 2nd, 

 and of a surety it was a case for prompt action if the trees were 

 to be saved. There were differences, of course, end some groups 

 of trees were not so bad as others ; but all were so bad that unless 

 the trees could be relieved from the burden of insects then infest- 

 ing them, they would probably never put out again. I do not 

 wish to suggest that no good had been accomplished by the appli- 

 cations made. On the contrary, I doubt whether any tree would 

 have been alive without them.' Only it demonstrated clearly that 

 so far as peach is concerned, the lime .md sulphur combinations 

 are not to be relied upon for summer work. 



I had a small supply of "Kill-O-Scale," a petroleum prepara- 

 tion elsewhere referred to, and that I sent up at once and had it 

 applied i to 20, October 11 and 13th. The record of the trees 

 then sprayed is missing if one was ever made ; but the report 

 October 21st is clear. 



"Although there are millions of dead scales on these trees there 

 are still quite a good many living females and under a good part 

 of- these are newly bom larvse. There is also a very thin scatter- 

 insf of white sets and more or less dead ones. There are not 

 manv crawling larv?e on the trees and judging from the number 

 under the females there probably were many more which have 

 been washed off by the rain. Fully half and may be more of the 

 older sets are dead; and the foliage is a little mottled. There is 

 no difference between those sprayed on the nth and those 

 sprayed on the 13th." 



October 24th, P. ^I. "There are still a few live females with 

 larvne under them on these trees. There are also a few older sets :
