636 NEW JERSEY STATE AGRICULTURAL 



Mr. W'ilnion Newell. State Entomologist of Georgia, has 

 moditied both the proportions and the method of making, and 

 his formula is as follows : 



Lime 16 pounds. 



Sulphur 8 pounds. 



Caustic soda — commercial 8 pounds. 



Water 50 gallons. 



''Mix the sulphur into a thick paste with a small amount of 

 boiling hot zcatcr. Then add the caustic soda slowly (do not 

 dissolve the soda in water), keeping the mixture thoroughly 

 stirred. A brick red color will appear almost at once. Con- 

 tinue the addition of the soda, and continue stirring, adding 

 small amounts of hot water as may be necessan- to prevent the 

 mixture getting too thick. The soda should dissolve all the 

 sulphur in a few minutes, producing a clear, deep red liquid. 

 Unless the liquid is entirely clear, with no particles of undis- 

 solved sulphur remaining, the mixture must be heated until all 

 the sulphur is dissolved. // /V absolutely inifrL^^atii'C that all 

 sulphur be dissolved and a clear liquid obtained, before the linw 

 is added. To the clear liquid described, add the stoiie lime, 

 previously weighed out, and while it is slaking keep well stirred. 

 The completed preparation will ha\e the familic'r \ellowish 

 green color characteristic of the lime-sulphur prei)arations. 

 Dilute with cold water to the desired point and spray at 

 once." * * * * * * 



"The effect uptMi the scale by this wash is not as good as the 

 regular lime-sulphur wash, and in the case of badly infested 

 trees therefore, two sprayings should always l>e given, the tirst 

 in December and the second in February before the buds open." 



The essential peculiarities of this wash are : That a chemical 

 combination changing the sulphur and soda into liquid form is 

 produced before any lime is added, and this combination unites 

 readily with the lime; that it contains more caustic soda and 

 less sulphur than any of the other formulas; and that the actual 

 diluted material for spraying there is only one half as much sul- 

 phur and lime as in the original New York fornnila. Ne\erthe- 

 less, Mr. Newell ranks this as one of the best three winter washes, 

 the boiled mixtures being given the precedence. I'each and 

 plum, especiallv the former, seem to luwe been chielly in mind 

 in all the suggestions made. 



I recommended the combination as published in Bulletin No. 

 169. thnmghout the winter of 1903-04. in all cases where only
