EXPERIMENT STATION REPORT. 645 



More than half of it was gone at the beginning of August, and as 

 soon as what remained began to show a tinge of color the rot set in. 

 Eventuallj^ not a fruit ripened, the rot destroying each before it 

 matured. 



Scale larvse were first noted June 25th, but the brood was not heavy 

 and had ceased running July 16th, at which time some of the foliage 

 had a scalded appearance, due to the spray that slopped over when 

 treating tree 18. July 22d, applied fish-oil soap at the rate of one 

 pound in six gallons of water, and this caused serious injury. Many 

 of the leaves were burned at the edges and were browned, while others 

 wilted, turned yellow and dropped. 



Early in October much of the foliage was already off, while more 

 of it was ready to drop at a touch. Some was yellow and discolored, 

 but quite a bit looked green and firm. On the 24th, sprayed thor- 

 oughly with "Scalecide,'^ one part in twenty parts of water. 



Tree 32 — Mountain Rose Peach. This was badly infested and 

 sprayed with "Kill-0-Scale," one part to water twenty parts, October 

 14th, 1904. March 6th, 1905, sprayed with Napthol-Sulphur, one 

 part to water thirty-two parts. The tree started ,normallY in early 

 April and developed as the season advanced. It had no bloom and 

 made a satisfactory growth, all the foliage being still present in late 

 October, when a good set of fruit buds had formed. 



May 27th, spraj^ed with an atomizer, soluble petroleum (sample), 

 one part to water thirty parts, to test the effect on foliage. A little 

 burning and spotting developed during the week following; but not 

 enough to be considered a real injury. 



JSTo live scales were found until July 9th, when a few recent sets 

 were seen and these may have come on from the outside. As the 

 season advanced the infestation increased slightly, and in October 

 there was a scattering set throughout. On the 24th sprayed with 

 "Scalecide," one part to water twenty parts, and covered well. On 

 the 30th the application was duplicated with equal thoroughness. 



Thee 33 — Dwarf Duchesse Pear. Was sprayed with "Kill-0- 

 Scale," one to twenty, October 14th, 1904, and with Napthol-Sulphur, 

 one part to water thirty-two parts, March 6th, 1905. During the 

 winter rabbits got at this tree and girdled one of the lower branches, 

 which died in consequence. For some reason this tree is a favorite 

 resting place for the few wild rabbits that come into the garden, 

 and it is the only one that suffers from them.
