COJ^CENTRATED LiME-SULPHUR SOLUTION. 



The iiicoiiveuienee experienced in preparing- the linic-snlphm- 

 wash by cooking with steam or in open kettles at homo has been 

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

 factnrers have therefore put on the market concentrated solu- 

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

 Avater for "use. These commercial washes have proved to be 

 {iliout as effective in controlling the scale as the well-cooked lime- 

 sulphur wash, «nd, although somewhat more expensive, have 

 been adopted l)y many commercial orchardists in preference to 

 tlie home-prepared spray. They are especially useful for the 

 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 on hand a stock solution, so that the spray may be 

 quickly prepared and advantage taken of favorable weather 

 conditions. These preparations should usually be used at the 

 rate of 1 gallon to 10 gallons of water.
