280 Peach-Growing 



There are numerous commercial brands of concentrated 



lime-sulfur on the market. Many growers prefer to use ', 

 one of them and if only a small amount of spraying is to 



be done it is probably more satisfactory to do so than to ; 



prepare a homemade mixture. Where large operations ! 



are involved, however, considerable expense is doubtless | 



saved by the grower making it himself. \ 



The equipment necessary to prepare the homemade i 



mixture, unless on a large scale, is comparatively simple. ; 

 A 75-gallon kettle and a 50- to 75-gallon water tank so set 



in masonry or brickwork as to provide a fireplace beneath ; 



comprise the essential features. i 



In large scale operations a more elaborate system of tanks i 

 and equipment for cooking the mixture by steam is advis- 

 able. Such an equipment is shown in Plate XXIV, where i 

 the barrels in which the cooking is done appear in the back on ! 

 the upper level of the "spray house. "" Cooking is commonly 

 done by steam, coils of pipe being placed in the barrels ' 

 or tanks and connected with a boiler. The ingredients ; 

 pass by gravity from one container to another when they 

 are brought together. The large containers on the lower j 

 platform to which pieces of hose are attached hold the spray 1 

 mixtures that are ready for use. '

lime-sulfur mixture as given by Quaintance ^ are as follows : :
