LIME-SULPHUR PLANTS. 
SIZE OF PLANTS. 
The size of plants depends largely upon requirements and whether 
the owner intends to make the concentrate only for his own use or 
also to sell it to his neighbors. Another factor that influences the 
size of plant is the time when the work will be done. If the concen- 
trate is to be made only as needed, the plant should be large enough 
to turn out concentrate in sufficient quantity to avoid any interference 
with the spraying work in the field. On the other hand, if a large 
storage tank is provided and the solution is properly protected, a 
smaller plant may be installed, batches made up during slack periods, 
and time conserved when spraying operations begin. Then, again, 
there is an advantage in having a stock always on hand for summer 
spraying and to supply neighbors who may wish to purchase small 
quantities at times when other work would have to be stopped in order 
to put the plant in operation. 
Lime-sulphur cooking plants may be grouped under two general 
heads, (1) small orchard plants and (2) large orchard or community 
plants. 
SMALL ORCHARD PLANTS. 
Small orchard plants may have capacities as low as 25 gallons of 
concentrate at a cooking, although 40 to 50 gallons are more usual. 
KETTLE PLANTS. 
The simplest plant consists of an old-fashioned caldron or kettle 
such as was once used for soap making or for scalding hogs. The 
modern form of stock-feed cooker can be adapted to lime-sulphur 
cooking. If used it is well to surround it with a 6-inch wall of re- 
inforced concrete, except where the door openings occur. If this is 
7On foliage of sweet cherry use one-third less of the concentrate than that given in the 
table of dilutions.
