EXPERIMENT STATION REPORT. 587 



Lime, sidphur and caustic soda has also been used successfully^ 

 bur probably to a limited extent only. Near Madison, Morris^ 

 county, large bearing apple trees Avere seen Avhich wore treated 

 Avitli this combination in 1904, and from which the scales had 

 almost completely disappeared. Some plum trees treated in the? 

 same way showed almost equally good results. Here also good 

 materials iuid thorough application counted heavily toward the 



I'O'^ult. 



Those who have used the lime and sulphur mixtures longest and 

 with greatest benefit now understand their limitations fairly well,, 

 and do not expect to obtain impossibilities. They realize that the- 

 right mixture must be obtained, and that it must strike the scale 

 to kill. They realize also that the mixture goes only where it i» 

 put, iuid that it has no spreading or creeping power. 



I advise this mixture for use on peach trees in preference to any 

 other because of the benefit derived by the trees, irrespective of the- 

 removal of the scale. Peach trees seem to be more easily covered 

 than any other variety of fmit, and the measure of success is pro- 

 portionately very great. With a full understanding of the limita- 

 tions above noted, the peach grower really needs nothing more 

 effective. 



As to the proportion of materials to be used, I still prefer for 

 the boiled mixture equal quantities of lime and sulphur, provided 

 tlio lime is good. If it is of poor grade, more is necessary to get 

 the 'luantity of actual lime that is needed. The consensus of 

 (►pinion, based on results throughout the country, seems to be that 

 the salt is neither Ci^sential to secure an insecticide effect nor ol^ 

 licnefit in forming the combination of lime and sulphuT 



SCALECIDE. 



''Sealecide'' is now made at Ilackonsaekj New Jersey, in a bricfc 

 building, close to the line of the Susquehanna and Western rail- 

 road, a siding from which runs tlie oil cars to a point whence it is 

 drawn directly from them to an underground tank outside the- 

 factory. C^onnected with the main buildings are storage and ship- 

 ping sheds of ample capacity for the prompt and economical hand- 

 ling of the crude and manufactured products. 



Concerning this outfit, which was visited by Mr. Dickerson and
