EXPERIMENT STATION REPOET. 641 



no injury was apparent, and while the leaves showed a coating of 

 resin, the scales did not appear to have been much checked. August 

 31st, sprayed thoroughly with emulsion No. 3, at the rate of one 

 part to water thirty parts. The wind was rather high and I could 

 spray only from one side and quartering — enough to reach all foliage, 

 but not all the wood. 



September 13th, more than half the foliage was gone and the 

 rest had numerous shot-holes, but crawling larvse were few and there 

 seemed to be less scale than at the date of spraying. October 1st, the 

 situation was not much worse in any direction, and the remnants of 

 the foliage hung on well and of good color until October 24th, when 

 the tree was sprayed with "Scalecide," one part to twenty parts of 

 water, but rather imperfecta, owing to a high wind. On the 30th 

 the application was duplicated and much more thoroughly, the foliage 

 yet as before. 



Teee 25 — Apricot. The tree started early in April and on the 

 12th was one mass of pink buds, just about ready to open. On the 

 21st was coming-out rapidly, and on the 22d was a mass of beautiful 

 flowers. Was out of bloom and growing well May 10th, and that 

 record continued until late in June, when, probably owing to drought, 

 the shoots stopped growing and the foliage lost its bright, vigorous 

 appearance. During the first days of July a heavy brood of young 

 scales was produced, and on the rather close esamination then made 

 it was found that there were several well-developed fruits present — 

 two of them already attacked by the rot. As this tree had never set 

 fruit before, none was looked for and thus it escaped earlier discovery. 

 None ripened, though some became fully colored, and all of it was 

 off by August 3d. 



July oth, sprayed thoroughly with "Anti- Scale," a petroleum 

 preparation, at the rate of one part to thirty parts of water. The 

 result was disastrous, the tree being almost defoliated July 9th, and 

 the remaining leaves wilted. Even the now exposed fruits were 

 spotted and suffered as much in their way as the leaves. As to the 

 scale, it was present in all stages, and while some were undoubtedly 

 killed, more than enough remained. 



August 19th, the second brood of larvse developed in goodly num- 

 ber, and the tree did not seem to stand defoliation or injury at all 

 well.
