THE HOME-MADE CONCENTRATED LIME-SULPHUR 
. WASH. | 
In Bulletin 306 of this Station, the attention of our fruit 
growers was called to the formula for a home-made concen- 
trated lime-sulphur wash. The steps required in mixing the 
ingredients and in cooking the wash are similar to those in 
preparing the sulphur wash by the common method. In the 
treatment of the Station orchards and in several rather ex- 
tensive co-operative tests, many barrels of mixture by the new 
formula were used, and whenever the preparations were ap- 
plied at efficient strengths, as indicated by hydrometer tests, 
satisfactory results were obtained on the scale and blister-mite. 
It is a convenient method of preparing a lime-sulphur wash 
and could be employed for several useful’ purposes by fruit 
growers who have had experience in making their own sulphur 
sprays. It should especially meet the needs of farmers owning 
detached orchards at considerable distances from the cooking 
plants. The advantages of this mixture are:—It has no coarse 
sediment to clog nozzels and to cause the rapid wearing out of 
the packing, lining and other parts of the pump, and it may be 
prepared in concentrated solutions to be diluted as needed. 
For the present we advise fruit growers, making their own sul- 
phur sprays for the treatment of the sc ale, to continue to use 
the common boiled wash for the larger portion of their opera- 
tions and to employ the concentrated solution experimentally 
until its effectiveness for this pest under their own conditions 
is thoroughly established. The history of the commercial con- 
centrated lime-sulphur solutions indicates that the average 
fruit grower prefers to use the prepared mixtures.
