CONCENTKATEU LlMK-SULPlIUK SoLUTIOJ^f. 



The iiicoiiveiiieuce exj^ericnced in preparing the linic-sn][»liiir 

 Avash \)y cooking with steam or in open kettles at home has been 

 one of the principal objections to this spray. Certain manu- 

 facturers have therefore put on the market concentrated solu- 

 tions of lime-sulphur wash which have only to be diluted with 

 water for use. These commerci:il washes have ])roved to be- 

 about as effective in controlling the scale as the well-cooked lime- 

 sul])hur wash, and. although somew'hat more expensive, have 

 been adopted by many commercial orchardists in preference to 

 the home-pre])ared spray. They are especially useful for tlie 

 smaller orchardist, whose interests do not warrant the construc- 

 tion of a cooking plant. In other ways, too, they possess ad- 

 vantages; for instance, those using the commercial washes may 

 always have <)n hand a stock solution, so that the spray luay ])e 

 quickly prepared and advantage taken of favorable weather 

 conditions. These ]n'eparations should usually be used at the 

 rate of 1 gallon to 10 gallous of water.
